Ramsond 10 Watt Solar Panel 10w W Monocrystalline Photovoltaic PV Solar Panel Module 12V Battery Tri

Ramsond 10 Watt Solar Panel 10w W Monocrystalline Photovoltaic PV Solar Panel Module 12V Battery Trickle Charging Charger RVI hooked up five 10W Ramsond panels and a SunRay 1500-3000W inverter the other day out back. My wife and I wanted to do a little experiment to eventually supplement our energy costs and see if having a backup system was feasible for our home use. So far so good. Initially we only hooked up two of the panels and eventually all five into a small array through the inverter/generator. As of right now, the system is running quite well and provides enough power to serve as a test once we invest in a larger system. The construction of the panels is more than adequate. We did have some issues getting it all set up, but that was partly our fault for not checking how to hook everything up beforehand. We'll probably upgrade to a 100W panel or ten later on, but as a test it seems like several 10W panels & one SunRay are an efficient beginner's kit. I'm sure I'll be posting an update once we upgrade to a heftier system.

Fantastic 10W panel and only 12" x 13"! Connected the panel to a Yuasa 7 A-Hr 12V battery through a home-brew solar power battery charger. Very happy with the panel and its ability to maintain a charge to the battery and run the low-power equipment attached. It is truly a 10W panel and I can easily draw 0.8 Amps without any reduction in voltage at 12.5 Volts. (10W = 12.5V x 0.80A)

This is a very well made product. Strong aluminum frame. Verified output is higher than the 10watt panel from instapark. I would definitely recommend this panel to anyone. It does NOT come with any pre-wired cables, which is why I took off one star.

Yuasa YUA1200901 Smart Shot Battery Charger

Yuasa YUA1200901 Smart Shot Battery Charger
  • Fully charges and maintains conventional and sealed maintenance free batteries
  • Fully automatic three level charge cycle for effective charging
  • Reaches 14.4 Volts peak charge, then automatically switches to float charging
  • Reverse polarity protection, spark free operation, durable construction and 6 foot leads
  • 3-year limited warranty

This charger has worked well for me, and I was amazed at how fast it was delivered. I ordered it on a Sunday night, and it arrived Tuesday afternoon. Gotta love that.

I was looking for a small charger for charging mid-sized sealed lead acid batteries that I have in some lawn and garden equipment, a motorcycle, and a gate opener.

These are your typical batteries about the size of a small brick. These batteries typically have small plug-in connectors, rather than large automotive terminals, and so typical auto chargers don't work as they have clips that are way too large.

This is a three-level charger, so it can both charge up batteries that are low, and can maintain a battery (float charge) without overcharging it. Lead acid batteries need to be topped up every few months even if they aren't used, and this charger is good for that purpose. Failure to maintain batteries will cause early failure.

The charger also has pluggable ends, and comes with alligator clips and ring terminals, so the one charger can be used with different battery styles.

This charger is too small for charging dead automotive batteries, at least within a reasonable amount of time. It provides up to 0.9 amps of charging power. That's ideal for these mid-size batteries, but auto size batteries need larger 4 to 20 amp chargers.

A friend told me that this was the charger he most often saw used at kart races, and thought very highly of them.

The charger is also pretty small, so it doesn't take up much space on the shelf, or in the tool box.

I received the charger today and couldn't wait to try it out on my deep cycle batteries. It works just great. The only thing I wish I had realized before I purchased it was that it plugs directly into the AC outlet....no cord. Other then that it seems to work. Went into charging mode when first plugged in then after batteries were up to full charge 13.4 volts it went into float mode. The instruction sheet says it would charge battery to 14.4 volts and then go into float mode but mine was 1 volt less then stated. 13.4 volts is about normal anyhow. In a nut shell I am very pleased with this unit so far, only time will tell how well it holds up. I would recommend this to a friend.

Bought this charger before Christmas to winterize my Yuasa motorcycle battery. So far so good, does exactly what it says and hook up is simple. Just plug to the wall and connect to battery terminals with clips or rings. Three led lights on the charger tells you the status of the charge. Pretty simple and idiot proof...

I purchased 3 of these units, 2 for my motorcycles and 1 for the cars.

They work well and even charge the car battery up pretty quickly. My son was working in the garage and had the car radio on for most of the day and ran the battery down.

Rather than pull out the bigger charger, I connected this one up and within an hour the battery was charged enough to start the car. I left it on overnight for added measure, but it did the job in short order. There are two ways to connect the charger. On the motorcycles, I used the quick-connect connector which bolts onto the battery posts for a semi permanent connection, allowing me to just plug up to the charger via a small plastic capped connector when the bike is parked for days. This connector on the bike tucks away in the frame of the bike when not in use. The other are two clips which clamp onto the battery posts. This one I used for the car. Both come with the charger.

MorningStar ProStar PS-30M PWM Solar Battery Charge Controller, 30 Amp 12/24 Volts

MorningStar ProStar PS-30M PWM Solar Battery Charge Controller, 30 Amp 12/24 Volts
  • PWM series battery charging (not shunt)
  • 3-position battery select: gel, sealed or flooded
  • Very accurate control and measurement
  • Parallel for up to 300 amps
  • Temperature compensated charging

I decided to put together a system with two 100-Watt solar panels, a couple of deep cycle batteries and a good quality solar charge controller, instead of the simple on/off type. I'm an electronics engineer and I used to design battery chargers for sealed lead acid batteries. I know how important it is for longevity and charge density to properly charge and maintain the batteries. Even in the best of all possible worlds any sealed lead acid battery is going to be down to about 60% capacity after 5 years, so these devices that maintain the batteries are important.

This product is well-built and appears to be of high quality. Initial setup and programming was very easy and the instructions go beyond instructing you to the point of adding a little education. I tested my system with volt and current meters and this device worked very well. It does exactly what it's supposed to do, it's nicely packaged and easy to use. It just works.

Black & Decker FL3WBD 3W Waterproof Spot Light

Black & Decker FL3WBD 3W Waterproof Spot Light
  • Rechargeable waterproof spotlight, Submersible up to 6 feet
  • Floats in the water pointing upward
  • Up to 10 hour runtime
  • Up to 192 lumens
  • 50 percent smaller than typical spotlight

The battery on this spot light lasts a long time. I recently had it on High for 140 minutes just to test how long long it would last. That is not bad at all for a rechargable spotlight.

This spotlight is a point object spotlight. Meaning it has a very narrow focused beam that travels a long distance. It is not good for illuminating a large area like a wide beam flashlight will do.

Flashlight tech has come a long way. This rechargeable pistol-grip 3 watt LED flashlight is amazing. I use it for boating and keep it at the bedside for protection--it is a blinding source of light.

I purchased it for $21 on sale and almost a year later, that feels like a bargain. Good job, Black and Decker.

I am a retired police officer . . we LOVE light sources and are constantly assessing them. We prefer an intense light that has great distance as opposed to one that throws out a weak, lateral flood light (just move the spot around, and besides, you'll have about a 30 foot diameter of lateral light in front of you) . . plus that intense spot. This is the most effective, powerful and intense hand held, portable light source I have EVER held and used. . . it is comparable to the spot lights mounted on our police vehicles . . I have NEVER been so impressed with any hand held light. The ONLY drawback is the "on/off" design, in that you need to use both hands to turn it off and on . . but considering the highly unusual capability of the light . . the switch's inconvenience is a small price to pay. I just purchased a second B&D light (same model) to keep in my truck (it has a vehicle power source adapter cord available . . call the 800 B&D number in the directions). It only charges when the ignition is "on", however, considering the time the light holds a charge, with normal use of your vehicle, it will stay charged. It's so small, it easily slips into the console. I have never had a flashlight in my vehicle in which I had so much confidence. It's an intricate part of my vehicle's standard emergency equipment . . fire extinguisher, traffic vest, glass punch, first aid kit, etc.

This light is an IDEAL gift . . they may not appreciate it at first . . but wait until they take it out and light up a tree 100 yards away . . you'll hear from them the next day. As we know, it's water proof . . and I can now attest, it's shock proof too. I inadvertently dropped it 15 feet to the unforgiving cement below . . no damage! I have had and used extensively, Stream Lights, Kel Lights, Mag Lights, Sure Fire lights and many others. NOTHING compares . . I'll never purchase another model light source. If you don't like it . . send it back (it will NEVER happen)! Everyone stay safe, Jim

Nextar NXBT-002 Solar Powered Bluetooth Cellular Hands Free Kit

Nextar NXBT-002 Solar Powered Bluetooth Cellular Hands Free Kit
  • Bluetooth Handsfree connection
  • Solar Charging
  • Caller name and ID displayed
  • Auto connect
  • Connects to your bluetooth enabled cell phone

I got this unit at another store,the reg price there was $99. We got it on sale (Black Friday) for a mere $21. Once I got it home and did the initial charge via the included dc charger-make sure plug is in and the oval ring around the big multifunction button turns "red", I've been using it. I had never heard of this type of bluetooth, I thought they were all the stupid looking earpiece things. One of my friends daughter had recently gotten a ticket for talking on cell while driving and had bought one of theses.

This comes with the window/visor mount. I use on visor since my window is a distance from me. When not using, I simply place on dash on a non-slip pad and it recharges in the sun...My friend who's daughter bought an LG model from AT&T for $78 says I sound MUCH better than she does on hers (she mounts to window). I also like the lcd display that I haven't seen on any other models. The volume on this is more than sufficient when all windows are up, down and I'm sure it would'nt sound well to both parties. One other thing, my wife was talking to my friend from passenger seat while we were driving and he could her her just as well and she was speaking in normal voice.

The build to this is very cheap (made in China-what a surprise). I read the others reviews and I'm sure there are some bad ones out there giving its cheap feel, but mine is working like a champ!!! I would NOT pay anywhere near the $99 reg price.

This speakerphone has the potential for being a very neat little unit, but it fails in its ultimate purpose: being a CAR speakerphone. While it may have good sound quality to the person you are calling if there is no background noise (in other words, if you're NOT DRIVING IN A CAR), once you introduce the whoosh of a moving car, you are rendered incomprehensible to the person listening to you.

_________

PROS:

Solar powered how incredibly awesome it is to not need to plug it in! No wires hanging from visors or windshields.

On/Off switch unlike bluetooth headsets where it is questionable whether it is on or off, this has a slider switch on the side where you can quickly and easily turn it on/off without holding buttons, etc...

Windshield or visor mount lets you choose where you want it.

Text display most bluetooth devices don't show you who is calling or what the status of the device is. This one displays it right in front of you!

_________

CONS:

Made in China apparently Nextar is a Chinese company. Kinda shows in the quality and feel.

Text display very hard to read if you're wearing polarized sunglasses. The kind you would wear WHILE DRIVING. Also, it only flashes information on the screen rather than keeping it there (to conserve power?), so it's easy to miss what it says.

Speaker at max volume (the kind you need on the highway) makes the holster vibrate (buzz) when the other person is speaking. The package comes with a scrap of sticky foam rubber that I think you are supposed to wedge into the holster somehow to dampen the vibrations.

Status LED the phone button is lighted from behind when the unit is on. Red for charging, blue for active. But it is VERY dim, so basically not viewable during the daytime.

Microphone With highway noise, although you may be able to hear the person you're calling, they can barely understand you. My wife said "You sound like you're in a tunnel and I can barely understand you", even if I tried to talk loudly.

------------

So, sadly, I had to return this because my main use is on the highway during my commute.

For such a small device, this thing is amazing. I had another solar charger mounted on the top right of my windscreen in my vehicle and it broke (because it got to hot... go figure). I found this one on another site (not amazon) and was able to grab 2, one for each of my vehicles.

Display This is the most inexpensive display bluetooth speaker (solar or not) that I have found. The display tells you when there is a call coming in, and will let you know when the call was disconnected. It also displays a little battery when it is charging via solar or the USB charger.

Speaker/Range Even with my low-end phone, the speaker works great. I do not have to take my phone out of my pocket for it to connect, but if I want to have a conversation, the phone has to come out. Once out, people can only tell I am on a cell phone, and not on a speaker or a bluetooth device. I can hear people even at high speeds with the windows cracked, very powerful speaker.

(The people complaining about the quality should check their phones against other bluetooth speakers before blaming this device for their call quality)

Usability Unlike most bluetooth devices, this one has a toggle switch that will let you turn the device on and off quickly and easily. The center button is used to make calls, disconnect calls and ant to ignore incoming calls (if pushed twice). On the side there are 2 volume buttons, up and down. The display tells you how loud or quiet the volume is (similar to that of a phone).

Initial Setup/Pairing This took maybe 30-45 seconds. Holding the main oval button on the device, I told my phone to look for devices. It found it, and paired it without any code or password. The display even gave a confirmation that it had paired with my device, and displayed both the name of my device and the model (i.e. BOBS-MOBILE LG VX10000)

Battery Life Its solar... as long as you are not in the North Pole in the Winter, you will be fine. Even so, they do supply a universal USB car charger (that will work with ANY USB cable...yes even iPod/Pad/Phone so you can charge it on the go. I haven't had any problems with battery life or talk time.

All in all this is an excellent product... and at around $20 dollars, I don't see why anyone would not buy this over those silly bugs that hang off the ear.

Want Nextar NXBT-002 Solar Powered Bluetooth Cellular Hands Free Kit Discount?

I have been using this device for 2 months now and it works great. The display is really handy for knowing whose calling and remaining battery life. For those having problems hearing from this device, try turning up the volume on the cell phone and the NXBT-002. If the volume is low on your cell phone so will the volume on the NXBT-002. Trust me when I say, this is a very good device and for $20 you just can't go wrong.

This unit is great for hearing aid wearing people. The only bad part is that the solar does not keep up with my usage (over 5 hours a day) but with the plug in adapter it just keeps on going. Great price , I have purchased devises which cost over $ 80.00 which do not work as good as this unit.

RoadPro RP-203EC 12V 12' Extension Cord with Cigarette Lighter Plug

RoadPro RP-203EC 12V 12' Extension Cord with Cigarette Lighter Plug
  • Plugs directly into cigarette lighter socket
  • Extends your 12-volt power source
  • 12 foot heavy-duty cord
  • One male plug to one female socket

Use only for low current applications.

My cable was marked 0.75MM (squared). A web search showed this to be somewhere in between 20 and 22 AWG.

The wire size should be given in the Amazon listing. This cable would probably be fine to charge an iPhone or iPod, but I would not use it with any tools, larger lights, air compressors, etc. (I could find no fuse.)

The AMP rating is not on the wire, nor on the packaging, so do your own careful research before using.

Other than the low current carrying capacity the quality of construction looks good (made in Taiwan not China).

I bought this so I could charge my cordless tool batteries in the cargo area of my van, and keep the clutter out of the cab. It did not work out so good, the wire is too thin to use on a battery charger that only draws 5 amps DC. The batteries would not correctly charge due to a low voltage condition the thin wiring caused. So I am not sure what kind of accessory this thing is good for?

I had one of these that got daily use for about a year before the socket portion cracked and I had to replace it. Even so, I'd definitely say that I got my money's worth and it worked fine up until that point. I bought it again as a replacement. The cord is pretty long, so you if don't really need 12 feet, you might want to use to twist ties to keep a portion of it wrapped up.

The VERY first time I used it the solder broke when I pulled it out of the cigarette lighter. I gave it 3 stars just because of that. They did not have anything to hold the wire in place with the male plug except for the 2 very small amounts of solder used to connect the wire to the male plug. I got out my soldering iron and re-soldered it back in place, put it all back together and wrapped the whole thing in electrical tape. So far this seems to be working. If it snaps again I'll buy a better male plug. My advice would be to wrap the plug with electrical tape and down a couple of inches on the wire to hold the thing together before you use it the first time. Come on RoadPro, there are better plugs out there than that POS. Other than that it worked perfectly with my Coleman air pump I use for my inflatible raft and bed.

Actron CP7612 Battery Load Tester

  • Chrome-plated steel housing with rubber grip handle and side test clamp holders
  • Features heavy-duty momentary test switch
  • Extra heavy 12 leads with strain relief and color-coded, insulated, copper plated steel clamps
  • Battery load tester accurately tests the condition of the battery and charging systems

I have two Hondas with their original OEM batteries and I was getting concerned about the batteries' health. It's a pain to get two cars down to the auto parts store for testing (by folks who may not be neutral about the results) so I invested in a Actron CP7612 tester. It's simple to use to test a vehicle's battery and charging system.

As other reviewers have noted, the tester can get very hot if the spring-loaded test switch is held in the "on" position for too long but my unit only got warm during the 10-15 second test specified in the instructions. The product is robust enough for the DIYer, with heavy connecting cables and an acceptably rigid sheet metal enclosure for the test element (heating coil) and meter.

I bought this today at a local auto supply house at a cost of $60.00 plus $3.00 state sales tax. Obviously Amazons' price is much better, but I wanted it NOW to test a battery that had been drawn down to 2 volts. I had charged the battery and brought in back to a steady 12.75 which is where it should be, but I wanted to determine if it would hold a charge. The Actron took just 10 seconds to verify I should be able to trust the battery OK. And not have to buy a new one. So in the end, it saved me $52.00, as the new battery costs $115.00. expensive I know, it is a Harley Davidson motorcycle battery.

In all four previous reviews and in the product description there is no mention on how long these cables are!

I bought this to use with a Vivair air compressor that draws about 15A. It will work off some accessory sockets, my bimmer works for instance, but not for very long without the engine running. In my truck, the amp draw is high for the accessory socket and it is only active with the engine running. This is a bit of a pain when you want to check and air up your tires. So I clip this to the battery terminals and I am good to go. The clips are not huge but work fine for me and the construction overall is fine. It is nothing very fancy but it is well worth the modest price IMHO.

Works as advertised. The little clamps should be much bigger the same size as what you have on light duty jumper cables. This way they would connect securely. Also, the short wire supplied should be a tad thicker. Main concern and 4 stars is b/c of the clamps being small and not very secure on battery terminals.

I bought this cable to go along with the viair 85P portable air compressor, that way I didn't blow fuses.

As soon as I opened the cable, I noticed it was only a couple feet long, which is not very long, but I was happy anyway.. The clamps also don't open up far enough to connect to a battery terminal securely.

I took it outside and plugged it up to my compressor, popped the hood of my car and as soon as I opened the clamp the positive wire fell out of the clamp.

Once I inspected the wire and the clamp, you could clearly see there was almost NO solder on the wire, and what little bit was on it was a "cold joint". The cable was also not crimped to the clamp like it was suppose to be (it looks like someone forgot to crimp it) , which is another reason it came apart.

I went ahead and pulled the sleeve off the negative clamp and noticed it WAS crimped (unlike the positive clamp), but the solder was also very little and cold-jointed.

Both clamps were also forming rust around the solder connections where the wire goes.

LUCKY FOR ME, I own a soldering station, so I disassembled both clamps, cleaned up the rust, re-soldered them on PROPERLY and THEN crimped them. They work perfect now and should never come loose again.

This is the first time I've ever rated a product 1 star, but when it literally falls apart as soon as you remove it from the box , it deserves 1 star.

I'm just glad I wasn't stuck somewhere on the road with a flat when it fell apart on me. Luckily I ALWAYS test my equipment before I rely on it for emergency use.

I wouldn't recommend this product unless you own a soldering iron and want to take the gamble of fixing it yourself or returning it to amazon.

EDIT: I bought another set of these cables, and they were properly crimped and soldered, I will upgrade my rating from 1 star to 2 stars, but RoadPro needs to improve their Quality Control.

Very handy to toss in the trunk. Using this will protect your ciggy lighter socket that could get overloaded. Every car should have one. I use it for an air pump and a very powerful camp light.

Note, most lighter plugs are limited to around 10 amps by fuse or circuit breaker in addition they have long run of small (higher resistance) wire to the jack which 'may' cause a voltage drop to your equipment.

Short of 'hard wiring directly' this is the next best thing.

This has none of that and of course it's the same as hooking directly to the battery so know what you are doing (sparks, load, polarity, fingers)...

I installed the previous version of this unit to provide solar power to my electric garden fence on 06/04/2011. It remained in continuous use without problems for 270 days then failed. My garden is in SW Oregon, so we do get a lot of rain. The maximum temperature range during the service time was from 85F to 20F. The led tube display is completely obscured by condensation inside the unit which would tend to make me think that it was not properly sealed and in fact was not waterproof as advertised.

My advice to purchasers would be to make sure you protect the unit from rain as much as you can without impairing the necessary ventilation around the product. If you do decide to buy this product, you should probably look for a way to protect it from the rain so long as you allow proper ventilation.

I do feel that the controller I purchased was in fact faulty and should have been replaced by the supplier. They did not want to do that and their warranty is in fact 200 days.

Just be aware if you buy this controller with the intent of installing it directly exposed to the elements you should plan on replacing it in 9 months.
