Purchased this for running a few low power items when the utility power is out. Very impressed with the build quality of this unit. It does provide the rated 300 watts without overheating or shutting down as long as adequate ventilation is provided, these do generate heat that must be dissipated. No complaints here considering the cost.

I purchased this inverter thinking it would be at least ok compared to the true sine wave model. Truth is it's not even close. It did, however meet my needs as a backup unit.
It was able to deal with a 200W light load, but anything over that and it struggled. It will also run a very small motor, like a coffee grinder.
It is also much smaller than described. I was pretty surprised when I opened the box. Actual size is 5.75 x 1.75 x 3.5"
In conclusion, it's adequate for light tasks and worth it's bargain price. If you need a real and clean 300W, go for the true sine wave unit

Bought this to run a 27 inch TV in our travel trailer and it works perfectly! I have it hooked into the 12V plug in and no problems powering basic electronics. I expected the fan to be louder, but truly it isn't bad. I would highly recommend this product and you can't beat the cost!

I have only had it for a week, but so far I am very impressed. I use it to power my 2.1 computer speakers (200 watts) and it is beautiful. Also since it has 2 outlets, I can charge my phone in my car at the same time! Great product, great price. Cig lighter hook up is MONEY!

Worked for a week and then shorted on the input side. Blows fuse when OFF.
Threw away the paperwork and it's easy to see why the unit only has mailing address and phone number (NO email address) on it. I'm pretty sure I could mail it back to British Columbia, Canada (for about what it costs) and they'd send me another one but it would be less hassle to just order another one... and that's how they getcha.

I purchased this inverter to power a 200 watt 2.1 Klipsch desktop speaker set.
I didn't have high hopes that it would eliminate the interference "buzz" from my old inverter but it actually silenced it 100%.
The fan in the unit is a little loud but nothing compared to the old buzz.
I'm very happy with it.

It loses a star for the POS/NEG hookups in the back - your only options are to have them come out to the side or have them facing the middle covering the fan.

Must have item for converting 12 volt power to 120 for appliance use. Well may, not too big, and good for camping.

This inverter seems to put out a very nice waveform. My "wall worts" are all quiet running off it. It also seems to be compatable with a Kill-a-Watt meter. this is very handy. I found the fan to be very loud and I don't think that you would want to have this in the cockpit of you car. It would likely be OK in the trunk when the car is running.

I was very happy with this thing until I broke it. I did something silly; I used it to run a gas stove. After about 5 kicks of the igniter there was a rather bad smell. I opened it up and the fuse was gone (a good thing) and a Mos-FET was in pieces (a bad thing). I have looked around and can't find out what the power draw is for the igniter on a kitchen range, so I don't know just how much I over loaded the poor thing. With the price of these things you can afford to blow up quite a few of them though.
