Go Power! GP-SW150-12 150-Watt Pure Sine Wave Inverter

• 150 watt continuous pure sine wave inverter 12 volt input
• 260 watt surge
• 2 AC outlets to plug into
• Over voltage, under voltage and overload protections
• 2 Year warranty

Pros: This is a very good looking inverter! I really like the sleek design and clean look. Has a pretty decent manual too. I like that the 12-volt accessory port plug (like you'd plug into the cigarette lighter outlet in your car) and wires are attached. The sine wave is PURE as measured by my instruments. (I also read a frequency of 59.9hz which my same instruments also read my commercial power at.)

Cons: This thing can't handle a load! Using a 12 volt, 35 amp hour battery pack, I hooked a 75 watt load up to it. I had a Kill-A-Watt plugged into the back of the inverter and had the load plugged into the Kill-A-Watt. The voltage level with no load attached and with using a fully charged battery pack (battery pack voltage level 13.21v DC), the Kill-A-Watt showed the inverter's output voltage to be fluctuating between 113.3v and 113.8v AC. When a 15 watt load was attached, the output voltage dropped to 112.5v AC. Bumping the load up a little caused more drop:

Load in watts with its respective Go Power! inverter voltage

0w 113.3v AC

5w 112.8v AC

15w 112.5v AC

24w 112.0v AC

43w 111.1v AC

73w < 104.0v AC (attached devices powered themselves off due to low voltage)

Is my Go Power! defective?

Additional con is the location of the on/off/remote switch. There are two AC outlets on the back of the unit. They are on the Go Power sideways! The power switch is located to the immediate right of the outlet on the right. If your plug is a bigger than the outlet, you cannot turn the switch on or off. You will have to use an extension cord. (An extension cord was NOT used in my test as I was able to plug the Kill-A-Watt into the outlet on the left side -which covered most of the right-side outlet too.)

I replaced the Go Power inverter with a Xantrex XPower pocket inverter (175 watt with a modified sine wave). Using the same battery pack, I was able to run the same load for over 5 hours! The voltage stayed between 114.0v and 116.6v the entire time the load was applied. The Xantrex was only a fraction of the cost of this Go Power inverter.

I intend to return this Go Power inverter and will try a different brand for my pure sine wave inverter needs.

This company makes a great product. We have it running in fairly harsh conditions, protected in a NEMA cabinet. It runs an irrigation controller (as part of a solar setup), that is too far from any power source to run power from the grid. Of course, it is one component in the system, several other items are also needed, so do your homework regarding load, protection, etc.

I bought this inverter over a year ago to run my laptop in my truck. I do a lot of traveling and I am on the local ferry quite a bit. I like to watch movies on my laptop and do not want to kill the battery. I have used the Go Power! inverter for hours on end without an issue off of my car battery without issue. I also use this inverter when camping. I just hook it up to my cigarette lighter in my RV and it can run my LCD TV with built in DVD player and I also run my BOSE ipod dock seperatly. I have run the BOSE player for 3 days (about 8 hours a day) straight off of the inverter and not once did I have an issue. This has been a very reliable inverter and I do recomend it to anyone that needs pure sine power for sensitive loads such as laptops tv's or stereo systems. I had used modified sine wave inverters in the past because they are so cheap, but they had static on my stereo and really heated up the cord on my laptop.

Bought this for a 143watt application based of the specifications of the device I was using and worked for a while until it kept overloading. Would have to turn it off, reset, and try again but same result. Buy only if your application is definitely under 150watts. Mine did not come with a cigarette lighter plug just soldered 10 gauge wire ends that hook up to the inverter via anderson power connectors, so be prepared when planning for your own situation. Also it is quite large and heavy for a 150watt inverter, though it is remarkably quite. Most of the cheaper modified sine wave inverter are incredibly noisy and always on. This one only came on under heavy loads.

Family uses it on long trips in the minivan running the laptop and other stuff. I even used it during a blackout for lights in the house. Came in handy.
