Black Car Charger/ iPod/ iPhone 4G/ iPhone 3G/ iPhone 3GS

Black Car Charger/ iPod/ iPhone 4G/ iPhone 3G/ iPhone 3GSProduct broke within 2 days of purchase. Wires came right out of charger base. Would not recommend to anyone

This charger is a little more cheaply made than I thought it would be. I have to continually check the connection to my phone because it seems like it keeps slipping. I use my phone a lot, so I require a car charger to keep it from dying on the way home from work. I may eventually replace this one with a more durable model.

I only used this product two times. Although, it was two times over a period of two months. When I received it, I thought it looked a bit cheap but it worked perfectly fine when I plugged it in my 3G. I had no problems with it while it was working. Then suddenly, when I tried using it a third time, it had stopped working. Probably a connection problem because the red light indicator showing it was receiving power from the cigarette lighter was on.

Equus 3721 Battery and Charging System Monitor

Equus 3721 Battery and Charging System Monitor
  • Displays the condition of the battery and charging system
  • Designed for 12-volt negative ground systems
  • Protects the engine computer and 12-volt accessories from surges
  • Easily plugs into a cigarette lighter or power receptacle
  • Head pivots for easy viewing and angle adjustment

The picture on Amazon site is not correct. This battery monitor shows the voltage value with .01 precision (or two digits after decimal point). That is far more then enought to tell the battery status. I put it in the car, it automatically switches between "battery status monitoring" and "charging status monitoring". When the engine is stopped, it is in "battery status monitoring mode", when engine is running, it will be in "charging status monitoring" mode. Amazon's price is even bettern then Walmart. Definitely a great value buy. Will recommend this item to my friends.

Seemingly just another auto gadget fortunately the Equus 3721 is more sophisticated than its ponderous description. A breeze to connect to any car's 12 Volt electrical system. Simply push into the lighter socket or an auxiliary power outlet now found in many newer vehicles.

With the engine running the instrument constantly displays battery condition with an LED light; amber when marginal, red if the battery is discharging. A green light indicates a correctly functioning electrical system. All is well with both battery and, most importantly, the alternator.

The Equus is also an accurate voltmeter. Digital read-outs give exact voltage in the electrical system. Potential alternator problems or a failing battery will be indicated by below normal voltages, plus an amber or red light. Extra information is a battery icon graphically showing total battery charge. Tending towards erratic read-outs, and therefore unreliability, it is not the unit's best feature.

Equus's instruction card is easy to understand. The unit is well made, sturdy, easy to connect and to transfer to any 12 volt system not having its own voltmeter. Also, as a supplemental monitor in an RV, or a bigger boat with a remote 12 Volt outlet in a sleeping area far from the main instrument panel, overall battery condition condition can be monitored while camping or at anchor.

Good value for money; very useful. From personal use, recommended.

The Honda 2005 civic has a marginal charging system. This meter is ideal for determining when it is time to turn off the radio to reduce load on the alternator. Voltage reading is very accurate, much better than 1% as measured against a small Beckman pocket meter, which in turn has been checked against a Powerex Wizard aa cell charger. Warning lights function well.

Some things to note when using this tester: Standard voltage of a 12 volt battery is 12.6 volts. Some deep cycle absorbed glass mat batteries will read 12.8. This is after loading the battery by turning on the headlights for 10 seconds, to remove surface charge. Note that while the lights are on, the voltage drops quickly at first, then the voltage stabilizes. Turning off the lights causes the voltage to rise again gradually. After a few minutes the voltage will stop rising. If the voltage settles at 12.6 (or 12.8 for AGM battery) battery is charged, assuming that the battery is near 68 degrees F. Lower temps raise the voltage, higher temps lower the voltage. For a standard battery figure about 12.66 volts at 32 F and 12.54 volts at 104 F battery temperature, not air temperature.

After a car has been running for awhile with no lights, radio, wipers, AC, heat or window defroster, the alternator may cycle letting the battery voltage drop for a while before kicking in. This is OK provided the charging is steady shortly after turning on the lights. An intermittant alternator will cause the red light to turn on and off when headlights are on.

The bar graph for battery condition is not very useful as the meter has only voltage information.

The instructions do not state that this tester is for negative ground cars only, a small quibble as positive ground is not common.

Had I bought this device six months ago I could have avoided killing a brand new battery in six months.

UPDATE: Still working fine as of Aug 2, 2012

Want Equus 3721 Battery and Charging System Monitor Discount?

I purchasted this unit to use in a small aircraft that has no built in battery monitor.

The unit failed within one hour of use.

It was too cheap to bother to send back so I took it apart.

I found two loose screws holding the circuit board and display in place and a bad solder joint.

I repaired the solder joint and tightened the screws and the unit has been working fine ever since.

Unless you are an Electronic Engineer like me I would not recomend this unit.

Strangely enough, the internal components appeared to be high guality.

It was not assembled correctly.

It's OK if it works.

just got the monitor from amazon based on the reviews here. the actual device is slightly different from it looks in the picture, with rounder edges. i guess the new product has been revised. also the protective plastic film is extremeply easy to peel off, a bit too easy i would say. or it might have something to do with the weather. here in singapore it's 30C all the time. the device has good build quality. the monitor can show two different tiny icons above voltage reading, under the battery and charging modes. the LCD is clear with bright blue backlight. basically it doesnt cost arm or leg but does all i expected. i will leave it plug in all the time in my car. i am sure i will be alerted by the unusual low voltage one day to realise the time to replace my battery. that will be the time i can recover the cost of this product by saving the expensive recovery service.

Arkon TT221-USB 12V Lighter Socket Mount with Integrated Mini USB Power for TomTom GPS

Arkon TT221-USB 12V Lighter Socket Mount with Integrated Mini USB Power for TomTom GPS
  • Includes custom fit adapter plates for ALL TomTom GPS Devices except TomTom GO2405 and 2505
  • Plugs into all vehicle 12V power socket and installs easily with no tools required
  • Provides Power to TomTom GPS Device without the need for power chordNOT compatible with Traffic enabled GPS
  • Swivel and Tilt adjustments for the perfect viewing angle

works fine for my Tomtom. However, the actual part that plugs into the cigarette lighter could be more tight. It is a little wiggly and the GPS shifts in sharp turns. Also, would be nice if the arm that holds the GPS would be longer or extendable. Unfortunately it is so short, that it interferes with the shift stick. When putting the car from D to P I need to move the GPS a bit because its in the way. Other than that I prefer it to the suction cup holder on the window.

PAC Ground Loop Isolator for 3.5 MM Applications

PAC Ground Loop Isolator for 3.5 MM Applications
  • Great For Portable Xm/Sirius Radios That Have Noise When Plugged Into The Vehicle
  • Use with sat radio, mp3 players
  • 3.5" noise filter

I don't normally write reviews, but I didn't see any for this product and took a chance on buying it, and it worked out well, so I thought I should write one.

I have an iPhone that I use to play music via the aux-in port in my Prius and there was a lot of noise in the signal, especially if the headlights were on, and this was particularly problematic if I turned the volume way up for soft music (e.g. Renaissance lute music).

With this noise filter, that problem is gone.

Buy PAC Ground Loop Isolator for 3.5 MM Applications Now

I have a car stereo with an AUX-in port. Unfortunately, when my car is running and I have my iPod plugged in, I get a very obnoxious electronic whine (more noticeable during the summer at night, with the headlights on and the ac running...the more electrics running in your car, the louder the whine). It would get so bad that it would make listening to music more of an annoyance than anything.

Searching on Amazon for an auxiliary charger for my iTouch, I came across this in a "Buy these two devices together and save" item. And I am happy to say it completely eliminated all electronic whine/feedback. It could not be simpler to install...plug one end of the isolator into your AUX port, and the other end into your iPod/mp3 player/auxiliary accessory(Griffin AutoPilot FM Transmitter for iPod, Kensington LiquidAUX Auxiliary Car Kit with Remote for iPod; iPhone 1G, 3G, etc.) It works like a charm. The way it works is its circuitry isolates any ground loops in your stereo (depending upon how it was installed, you may have a bad ground and that can cause an annoying whine).

HIGHLY recommended for anyone who wants to listen to their music and charge at the same time.

I have an old school 15gig iPod which is great in the car because the buttons aren't on the click wheel. Well, the battery doesn't last anymore and everytime I played it with the battery adapter on, you could hear the whine from the alternator on acceleration. After plugging through the PAC, silence. I dare say, the music actually sounds better! Very, very satisfied.

I don't know what this thing really does, but it is magic. Without it, plugging my NookColor into my decent quality portable speakers created awful static noise. The noise was so bad that I almost returned the NookColor as defective (my ipod and cell phone work fine with the same speakers). A friend recommended this PAC device, which he bought for $20 at a local car stereo store, but I bought for $13 here at Amazon. It is magic. Music played from my NookColor now sounds wonderfully clear.

The PAC device uses no batteries; just plug it in like a headphone cable. My friend says it matches the impedence from a music player and incompatible speaker systems. I don't know what that means, the Amazon description is not helpful, and the device comes with no useful documentation, but it really does work.

I hooked my PC up to my TV and my home theater system and was getting some terrible humming in the line between the PC and the sound system. I put this ground loop isolator on the line and like that, no more unwanted noise. Highly recommend this if you have a hum from an AUX cord.

  • Belkin F8Z361Tt06-P Iphone/Ipod Av Cable

The Belkin web site and the box implies the iPhone 4 isn't supported so I passed the first time around. Since the return would be easy at a local store I tried the 2nd time. Never used one of these before and it didn't seem to work on any of my devices. None of the devices listed on the box or web site match what I have.

But, you have to know that (apparently) the iPhone/iPod doesn't send any A/V signals out the dock connector unless you start playing something music/video. Once I figured that out, ALL my devices work just fine.

Plus, it's a nicely made assembly.

I purchased this for my iPad2.

The description does not mention iPad, but it works just fine. I can see AirVideo output just fine with sound and charges the iPad2 at the same time.

I do however have one HUGE gripe. The connector dislodges from the iPad VERY easily, which of course keeps it from charging and disrupts the external display. Very annoying.

I managed to mitigate that occuring however by simply attaching this 15' extension cable SF Cable, 3 RCA Male to 3 RCA Female Audio Video Extension Cable-15 Feet, so now I can watch my living room Win7 MCE recordings (wtv files) on the bedroom TV upstairs and keep the iPad within easy reach on my nightstand.

Also, I find that I need to use the 2amp charger that came with the iPad because the video would just not show up using my HTC 1amp charger.

Tripp Lite APS750 Inverter / Charger 750W 12V DC to 120V AC 20A 5-15R 2 Outlet

Tripp Lite APS750 Inverter / Charger 750W 12V DC to 120V AC 20A 5-15R 2 Outlet
  • 750 watts continuous output power; up to 1500 watts instantaneous power
  • Extended peak surge power handles heavy connected loads
  • Auto-transfer switching option for battery backup (UPS) operation
  • 2 AC outlets; rugged moisture-resistant polycarbonate housing
  • 1-year warranty

I have an off-road trailer that I use for research. I purchased the APS750 and coupled it with a 105 AH AGM battery in the nose box of the trailer. Away from mains power, it provides excellent run time for several laptops and communications equipment. I keep the battery charged with solar panels off-road and take advantage of the 20A charging capacity of the APS750 when mains power is available. It's a 750W sine wave inverter, transfer switch, and battery charger in a rugged package perfect for my needs. I highly recommend the APS750 for mobile applications where high quality and reliable power is important. I can see where it might make a good emergency power system too.

[Edit Sept. 21, 2011: In my original review I stated that the Tripp Lite APS750 was a pure sine wave inverter. I removed that statement from my review as I learned through investigation that the output is pure sine wave when running on mains power (as expected) and PWM (pulse width modulated) sine wave when running on battery. PWM sine wave should not be confused with the fixed square wave output of cheaper inverters. PWM provides tight voltage regulation (+/5%) and eliminates harmonic noise the static hum you might hear with sensitive equipment if run on a cheaper square wave inverter. PWM sine wave is suitable for sensitive electronic equipment and motors. Anyway, I've been running sensitive radio communications equipment and computers on my APS750 with no problems.]

I use this as a backup power source for my pellet stove. If the power goes out when the stove is on, you get a smoky mess since it relies on a fan for combustion and exhaust. I chose to go the APC route instead of the stove-branded unit I feel more comfortable with a company that knows this business well. I could not be happier with it fast switching, charges the battery fast after the outage too. Ultimately simple as well the switch is either off, or automatic or charge-only. Set it and forget it!

Here in South Florida, we have what would be described as unpredictable weather... which leads to unpredictable power ;-). Since I work at home on the computer, I need to be able to work through our unexpected power outtages which can last several hours at a time. My UPS just wouldn't cut it for power outtages lasting more than an hour or so.

Enter the king of UPS's, the APS 750! I bought a marine battery at Walmart for under $70 and connected it to the unit. Just the one battery gives me about 5 to 6 hours of run-time for both my desktop and my LCD monitor. If I need more run-time, I can simply connect more batteries in parallel.

Like a regular UPS, the unit charges when it has power, and switches to battery during a surge or blackout. Though the transfer time is a bit higher than a typical UPS, it doesn't seem to matter.

OK. This is VERY important. This unit does NOT output a real sine-wave when on DC power. The output is a chopped up "sine-wave" which drops to zero volts many times over a single wavelength. This unit does NOT play nicely with most furnace or pellet stove blowers, certainly not my 1/6 HP blower on my Lennox furnace. NOWHERE IN THE ABOVE DESCRIPTION does it say that the output on DC power is a "PWM sine wave output". However, if you go to the Tripp Lite website, find this product and go to the specifications tab, this is what you will find:

LINE POWER (AC): Maintains 120V nominal sine wave output from line power source. INVERTER POWER (AC): Maintains PWM sine wave output voltage of 120 V AC (+/-5%).

Freaking great. So much for "clean, computer grade power". That is a load of B.S., honestly. If I had known, for even a second, that this unit didn't output a real sine wave, I would have purchased something else. Apparently, you have to get the TRIPP LITE APS1012SW 1000 Watt 12 Volt Inverter / Charger Pure Sine Wave 120 Volt 4A/40A Hardwire at approximately TRIPLE the cost to get a real sine wave output on DC power. So now I'm stuck with this thing, as I bought this thing, then researched batteries, then got that, then tested the setup out on stuff besides my furnace, then had to modify the wiring to/from my furnace by cutting it and putting an outlet in one box, and a power cord in another, so I could insert this setup in between furnace and mains power, and thus it's been more than 30 days. Nor will Tripp Lite help me, as it "clearly" says in the specifications that this is a PWM output on DC power. They will allow me to trade up to the 1012SW if I pay the difference in RETAIL prices.

So, yippee. Just dandy. If you buy this, make sure that you test it out within the return time on the actual equipment you want to backup power. And if you have a pellet stove, chances are it won't work according to what the Tripp Lite representative told me.

[EDIT]***FIVE STARS TO AMAZON CUSTOMER SERVICE!!!***

So I called Amazon mainly to tell them that they should add the PWM output on DC info to the product page, but also with the slim hope that they might be able to do something for me. And they WERE able to do something for me! I couldn't be more pleased with Amazon. This is precisely why I always try to buy from Amazon when I can![/EDIT]

I brought one of these down to Costa Rica to deal with the unexpected power outages that happen on a semi regular basis. I hooked it up to two 100 amp hour deep cycle batteries. This will run my lights, electronics, wifi, computer, and short use of tools for a day or more (maybe much longer/ never tested). I separate & leave equipment with higher energy draws (like the refrig, pumps, washer, dryer, air conditioner) off the same power out electrical line. When set to operate automatically, this inverter takes over and supplies the 120 volts of electricity from the batteries via inverter when your grid electricity goes off. This unit will also regulate the grid voltage when voltage drops low or spikes high. The batteries are automatically recharged when the grid electricity comes back on. Great product for good competitive price. In my opinion: This is the BEST DEAL on the market. I believe Tripp Lite knows what they are doing when I study their full line of products. I see they also make auto power supplies for medical use. 2012 Update: My Tripp Lite APS has been working flawlessly for 4 years in Costa Rica's humid beach climate. Another Plus: Any electric powered burglar deterrent hooked up to this system will work 24/7 including when the grid is off line.

  • Measures 12.5 feet long
  • Can be used with Battery Tender Junior Plus 4, 5 or 10 bank units
  • Sold as pack of 4

I'm a Battery Tender fanatic. I honestly think I need help. Maybe it's all in the deviously subliminal master plan to someday transition to an electric car? Anyway it's winter in the Northeast and the boat is in storage (three batteries) along with the waverunners (two batteries) and the motorcycle (except for a few warm winter days), not to mention the non daily driver car that sits. So everything is on chargers since I hate hitting the start button and getting nothing, having to wait, go get a battery, install, and miss an opportunity. Anyway, these chargers never had long connector lines. I had to move the box close to the battery and not too far from the outlets... Enough!....and then I found these extensions which solved my problems. Now I'm tucking (heavy) batteries away in corners where I don't need 'em for a while, and the ones leading into the car and motorcycle aren't getting tripped over knocking Tenders onto the floor. Love them. They work perfectly as long as I lable which ones were going where. These things are great and they work perfectly.

MACALLY External Battery for all iPods

MACALLY External Battery for all iPods
  • Ideal for long flights, outdoor activities, anytime anywhere iPod devices might run out of power
  • High capacity Li-ion battery cell increases iPod play time approximately 6-8 hours
  • Compact and sleek design
  • Standard USB port
  • Plug iPod shuffle directly, and use existing 30-pin USB sync cable (not included) for other iPod devices

****This review is mainly for those who has iPhone 3G or similar gadgets that have a battery capacity of 1,200mAh or more. If you have a device with less, this review may still be suitable for you but you can also consider other external battery chargers.****

I did tons of research trying to find the best external battery charger for my new iPhone 3G. I got say this, I love the Macally JBox. Seriously! I believe it is the best external battery charger on the market right now for it's size, weight, design, output, capacity and ability to check battery status.

I'm a power user because I spend most of my day browsing safari, listening to music and watching movies but 75~85% of the time making phone calls. Since voice call drains the most amount of juice, extra battery(ies) is a must for a business person like me. I had a Samsung Blackjack i607 before the iPhone 3G and I had 4 extra batteries in order to keep the phone running by the end of the day. Now the battery in the iPhone cannot be replaced easily so that's where external battery charger comes in handy.

Now which battery should I buy? I was wondering. Definitely not big or heavy ones that might give me a burden. I need something small and light so I can carry it in my pocket and charge my iPhone 3G at the same time on the go. Anything 2.5"x4"x0.6" and 10 oz or less would be perfect. How about let's try eBay since most stuff are cheap? *BUZZ* That's a big NO NO!! Most of eBay external battery chargers that have 9,600~20,000mAh are fake due to their small size and light weight. I did a little research by contacting at least 25+ people who purchased those products on eBay and most of their answers are the same. Those batteries are fake and have at most 1,200mAh. Cheap quality for cheap product.

Now how about ? The TY460 has an impressive 4,600mAh capacity, which is 1,200mAh more than Macally JBox. However, I don't trust the capacity of the iMaxPower due to it's identical size and weight as the JBox. Does eBay chargers ring a bell? Their small size and light weight yet mislabeled capacity? Now, let's just assume the capacity is 4,600mAh since I don't have one so I can't confirm it but take look at the output, 600mA. 600mA? That will take more than double the time to charge a cellphone/PDA than JBox. The phone controls the current delivery to the battery. If the battery can take the current the phone will allow what ever the charger can deliver. Anything lower and the phone will limit the supply to the battery. If the charger can't deliver the battery requirements then the worst that can happen is that it takes longer to charge! This is only valid for Li-Ion batteries. Because the current delivery is variable depending on the battery's state so a 600mAh charger won't take 2 hours to charge a 1200mAh battery. It WILL take approximately 3 hours!! My iPhone 3G has 1400mAh battery. iMaxPower TY460 will take more than 2 hours to charge the phone while JBox will take a little over an hour. The TY460 has identity size and weight as JBox but the design, color and quality did not catch my eye. In another word it's ugly and cheap. Also the "To Device" port is on the side as oppose to from the top of JBox. For those people like me who charges the phone on the go(I'm not talking about sitting on an airplane or train but walking around mostly) The "To Device" port has to be on top of the charger or your pants pocket will be tight and bulky unless you have a big pocket. Don't even think about the TY250, it's 350mA will take 4 hours to charge my iPhone 3G and probably will not even be able to sustain the phone if I make a long phone call.

Now how about ? Let's take look at the model 33396. Not the one that sticks into bottom of the iPhone but the one that's identical to the JBox. It has the same slick design as JBox. The output of 1.50A or 1,500mAh is impressive. It will fully charge my iPhone 3G in less than an hour. However, the unimpressive capacity of only 1800mAh really turned me down. A little over an hour charging the iPhone 3G it will be dead. Not to mention the price is $69.99 as oppose to $39.99 for the JBox.

Now, finally, here comes the biggest competitor(s), JAVOedge/Lenmar. I'm not sure which one is the original manufacture and which one is the reseller since they both have the exact same design, weight, size, capacity and output except the logo. Anyway, JAVOedge/Lenmar and JBox has the identical size(3.9"x2.4"x0.6" for JAVOedge/Lenmar and 4"x2.4"x0.6" for JBox), weight(4.2oz. for both) and capacity(3,400mAh for both) but outputs are different. JAVOedge/Lenmar has 700mA while JBox has 1,000mA. I bought the JAVOedge before I saw JBox. Everything worked fine on JAVOedge, the output and capacity were tested and showed satisfying result. Though it does not have battery status light but as least it shows green light when fully charged as oppose to the non-existence status of fully charge on JBox. Then I found out the biggest flaw on JAVOedge! It IS UNABLE TO CHARGE MY DEAD iPhone 3G!! When I say dead I mean the phone is completely out of juice. I sent an email to the company to report this problem and they have taken the product off their iPhone 3G category ever since and offered me a full refund including original shipping and return shipping if I were to return the product. Macally JBox, on the other hand, has no problem to charge my dead iPhone 3G. That's my biggest concern since I cannot afford to have a dead phone in the middle of the day and many times I find myself too busy to keep tracking the battery status. I do hope the JBox can have a little more capacity tho. Additional 400~600mAh would be perfect since I came home with a 10% battery on iPhone 3G and a dead JBox last night. Maybe I'll considering getting a JBoxmini but I dislike the idea to carry too much stuff in my pocket. I guess I'll have to find a space in my already packed suitcase for it.

All the good talks are done. Now let's move onto some imperfections JBox has. The battery status of JBox showed full 3 bars after only 30 minutes of charge from empty juice. However, if I stop charging the JBox after 30 minutes and use it to charge my iPhone the battery status immediately changed from 3 lights to 1 light. So I conclude the battery status does not show the right level while the JBox is being charged unless you calibrate it by charging it with something else. Another imperfection is the lack of ability to show whether if it's fully charged or not. Unlike JAVOedge which will show steady green light when the battery is fully charged and red when it's low, JBox however will always show green light as soon as it's been charged. The only time it will show red is when the battery is low. This creates a problem because we can't tell when the battery is fully charged or not. After several email to tech support Tom from Macally, he explained the green light will flash for 2 seconds once fully charged but how can one tell unless he keeps staring at the light for hours? Once you miss it it won't flash again. Then he explained further saying that after 2 seconds of flashing green the light will be turned off. I find that's not the case for my JBox. Either my JBox is defective on that small part or that information is simply not true.

Some additional information and misc. I collected from Tech Support Tom. The JBox will take 2.5 hours to be fully charged from empty and it has a protection circuitry inside to prevent overcharge. Some information on the box or specification sheet in the package is incorrect. The correct specification is listed below:

Macally Jbox IP-A481

Capacity: 3400mAh ( does not show the capacity but the package does)

Output Current: 1000mA max. (1200mA max. in the package label is wrong) Unit Weight: 4.2oz (JBox weights 4.2oz, entire package weights 5.0oz, the 11.3oz on the product info page is wrong, maybe they calculated the shipping box in?)

Buy MACALLY External Battery for all iPods Now

This is a great product. I used it on my trip to Germany with my kids and our new iPod touch. They were using it for a lot of video and I used it for web browsing in wi fi hotspots along the way. Unlike some of the less expensive options this actually charges your device. I did recharge the backup battery when I could, but I think I could have gone all week just using this to recharge. It has 3 lights that tell you the status of the battery life just by pushing a button which is really nice. It comes with a cord to plug into a USB port or USB wall charger to recharge the battery, even a simple case to hold the battery and cord. Very light and does not get hot when you use it. Simple to use, but powerful where it counts, battery life. Well worth it.

I bought this to use with my iPod touch. And it works great. It completely recharges the Touch from a single charge. I can charge the device by using the standard USB brick from Apple or the USB port of my computer. I just took a long flight 6 hours of flight time plus two hours between flights. I watched a two hour plus movie and two TV shows in addition to an hour or so of music and an hour or so of Internet browsing. Plugged into the charger when the touch got to 20% warning. Now it's fully charged again. Never had to fumble with the power cords or computer. Its small too, not much bigger than the Touch itself. Definately worth it and no batteries to throw away like those other chargers. Now we just need to see how long it lasts.

Love it! So nice to throw it in my brief case before a trip and not have to worry about how long my iPhone or iPod Nano is going to last. Easy to use, nice construction....I wouldn't hesitate to suggest it to others.

I bought this to have on hand in case my iPhone battery ran out while I was traveling. It works perfectly with iPhones as well as with iPods. I was even able to continue taking pictures using the battery. I plugged it in as soon as my iPhone warned me that the battery was in the "very low" range and it switched to the battery without a problem. The battery also has an "on/off" switch so you can avoid draining the battery when not in use. Also has a USB cord for charging and a small carry pouch. I just leave it in my purse now for those times when I run out of time . . .

The PBT 200 had no product description for operating ranges. This only tests up to 900 CCA which many batteries exceed. For only $20 more, the PBT 300 has a much wider testing range. No fault of Amazon, the test specs are not even on the Midtronics website. This is an ok product, but the PBT 300 is an all around better product because of its wider testing capabilities.

This is by far the best one! I bought the The sCharger-5 to charge it.... what a pair! They work great together if your looking for a power pack to store your solar power or just as a power source. Highly recommend this unit 5 Stars!

This product is OK

comes in a soft case just a little to big to fit in your pocket

Battery pack appears nice came 70% charge but it features an ON switch which turns on power to devices for 30 sec then based on power draw stays on or shuts off. WILL NOT RUN A PASS THROUGH E CIG

Came with a retractable cord charger, all the tips, nice blue case

Good construction on the battery (4 screws hold side metal plates on) would work well as a backup battery say camping

Battery is LARGE (physically) and rectangular

Company is terrible however I asked a question (like does this have a 30 sec ON switch? if so please refund my money BEFORE shipment) NO ANSWER and the product was still shipped

Schumacher IPD-1800 Instant Power Jump-Starter with Docking Station

Schumacher IPD-1800 Instant Power Jump-Starter with Docking Station
  • Portable, 12-volt instant power charger
  • Built-in halogen light for emergency or work zone lighting
  • 18 amp-hour maintenance-free lead acid battery
  • Integrated docking station provides power to start the car or truck
  • LED display indicates battery charge

The reasons that I bought this charger is because it has a docking stations which can be used to charge and store the unit when not in use. After the charging is completed, the docking station will enter a "floating charge" mode to prevent overcharging. Some other charger need to be monitored carefully since overcharging can damage the battery. With this unit, I can just leave it and forget it... Also, this unit is small enough that my wife can use it to jumpstart her minivan. Some other multifunction charger are so heavy, you'd have to be a weightlifter to carry the thing.

** UPDATE ** I originally wrote the glowing review below. This was a great product, while it lasted. Unfortunately, about 1 week after the 1-year warranty period ran out, the unit stopped accepting a charge. That is, I could not charge it either using the cradle or directly from the wall adapter. I called Schumacher and they could not offer me any help. A shame, but I can no longer recommend this device and I will be looking for a replacement.

UPDATE: I paid $88 for this when I purchased it in February, 2008. I see the price has increased, so I just wanted to note this difference so you take my comment about 'heck of a deal for the price' and 'comparison shopping' in the appropriate context. I am still very pleased with the unit but wanted to make clear that I am no longer completely certain that it's the best deal on the market. I have not recently done any comparison shopping to figure out if other units prices have changed.

Original review: Let me begin by saying that this is a sturdy, well-built piece of machinery. It also clearly can get the job done, period. My V6 Toyota Land Cruiser had a _completely_ flat battery, with a totally crudded-over positive terminal. I hooked this puppy up, and my engine ROARED back to life within 10 seconds of the connection being made. I haven't ever heard my engine start like that before, even when jumped from other jumper packs. Now, to comment on some other aspects of this equipment: It comes with a charging cradle, but you don't need to use it, because the AC adapter that plugs in to the cradle can also be plugged directly in to the jumper pack itself. So you can just stash the AC adapter in the car with the jumper pack, for mobile use. Also, this _can_ be used to power small appliances, but you'll need a cigarette-lighter adapter, because this doesn't have a regular outlet, only a cigarette-lighter outlet. Anyway, this is a heck of a deal for the price. I did a lot of comparison shopping to get the best value, and I'm very, very pleased.

I purchased this unit based on all the positive reviews, but unfortunately, I cannot say the same. I guess I must have received a defective unit. The main battery would not charge through the dock and the LED's on the dock were not in synch, as it showed full charge whether the main unit was attached or not, even before charging. The battery charged fine on its own and I concluded that either the dock itself or the battery contacts must be faulty. I could have done without the dock, but the idea of unprotected contacts being bare makes no sense. What made me decide to return it however was the unpleasant experience with Schumacher. After 3 days of calling, each time I was given the run around and they had no records of my issue (Like I was calling for the first time). Finally they decided I had to ship the entire unit (at my cost) so they can "test it". So much for customer service and warranty on a brand new unit out of the box. I decided to return it to Amazon and they paid for the return shipping. The 3 stars is a balance of 1-2 stars for the product, 0star for Schumacher, and 5+ stars for Amazon.

I use this as an alternate 12V power source to power a 12V

air compressor and it is a great product! It can power a

Spot Light(15 watts/12V) for 12 hours. So it doesn't have a problem at all when I blow up tires, floats etc.

I am very impressed with this product as far as it's dependability and ease of use. I had a problem with a battery drain on my vehicle in which the battery would be dead every morning when I would go to start it. I used this product every day for a few weeks to jump off the car until we could find the source of the drain. It worked flawlessly every time I needed it. I had always been scared to jump start a battery, but with this product, it is so easy I didn't have any worries. I could even throw it in the trunk and take it with me when I thought I might need it.

I have had it about 6 months now and I love it! The peace of mind is well worth it!
