Rated 5.0 out of 5.0 by True world test's performed! I picked the inverter up to test a few things and see what I could run and for how long. Let me first say this is a great inverter for the money. I have had it hooked to a 12v car battery for over 4 hours without recharge and did many things with it and it never dipped below 12v. I had a 360watt peek radio hooked to it the whole time at a good level so I say about 200watts is what it was pulling. I charged my cell phone from dead to full. I charged 2 Ryobi 18v batteries from dead to full 80 watts. A stream light flash light and extra battery 10watts and my laptop from dead to full it pulls around 100watts. The inverter fan has been running to keep it cool and the battery is still over 12v after 4 hours of straight use. This was a real world test and this product passed!! July 12, 2013
Rated 5.0 out of 5.0 by It does what it was made to do I have owned this inverter for almost a year now, and it has worked great. I have used it to charge and run electronics on long family trips. I ran a large fan while watching fireworks in a heat wave. It also runs my string trimmer when hooked directly to the car battery. The inverters fan only runs when the unit it connected to the car battery, not when using the lighter plug. Some electronics don't like a modified square wave and some do- you have to test them out. This is a handy, compact unit that does what is was designed to do, and I recommend it highly. July 27, 2012
Rated 5.0 out of 5.0 by Use it for my solar setup, hasn't had a single issue! I was very suspicious about how well this would preform for the first few days, as it looks kind of cheap in my opinion. Once I got used to it, I started trying heavier loads, and could run whatever I want that was under 500 watts. This is a great, cheap option for me as I am using this as an off-grid application. It powers anything I need it to besides a standard electric heater. It's also pretty water-resistant. I left it out where it can get wet one night and it worked fine the next day. I can even run a 750 watt wet/dry vac for about a minute to pick up some junk before it shuts off on me. Don't do this much, or it will burn out the inverter, I can guarantee you that. Many nights, I forget to turn off the inverter, and it doesn't waste but up to 0.1 volts of my battery bank, if that! This is designed to minimize radio interference, so it won't interfere with radio/TV stations you're enjoying as much at all. To calculate watts, multiply amps by volts. For example, 120V AC * 0.1 amps is 12 watts. If your thing is over 95 watts, switch to the 500 watt option. The fan only runs when there is a big load on it and it needs to run, to the people who think it is broken! It works fine and doesn't present any issues until you start getting into the big things, like a fridge, washer/dryer, or heater. An A/C works fine on it if you get a really good, efficient one, though. Good luck to you all, and I hope this review helped! December 20, 2013
Rated 1.0 out of 5.0 by Did Not Work I bought this for camping and the first time we put it to work when we was at camp it started working good for about 1 hour the cooling fan would turn on and work fine. but after that for about 5 minutes into being powered on it would shut down, not after awhile into trying to make it work we noticed that the fan did not turn on at all anymore and that would cause it to heat up and shut down.

Rated 5.0 out of 5.0 by Works just fine! I purchased this unit, hooked it up directly to my car battery and plugged in a fan turned on high speed... worked like it's supposed to. ( Vornado fan rated at 120V & 1.4 Amps.) If your car battery is below a certain level the inverter will kick out automatically so as not to run your battery down below a safe level for starting!

Rated 4.0 out of 5.0 by works well for what i use it for really works good, after a couple years I will give another review on durability September 22, 2015
Rated 5.0 out of 5.0 by Road Trip Life Saver With a 7 year old and an iPad in the back seat, I needed something to keep him charged up and entertained on long drives. I bought this and bolted it under the front seat. I have had no issues to date, and my son's battery never dies! #dadwins January 29, 2015
Rated 4.0 out of 5.0 by Good buy for the price So far, so good. I bought this to take with the family on a camping trip. I like the fact that you can plug it in inside the car for small needs, and to the battery for larger needs. I've used it on two trips, both times to blow up an air mattress for the tent. First time, it did it just attached inside to the outlet, but the second time, it would not do it until I attached it to the battery. Then it worked like a charm and much faster with the greater power than before. Wish it wasn't made in China, but for the price, was an excellent deal, as long as it keeps working. September 6, 2013
