Go Power! GP-300 300-Watt Modified Sine Wave Inverter

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

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!

The sine wave was not good enough to run electronics without serious interference. Additionally, the maximum wattage output for this device was 40w, rather than 300w. I am surprised that this product received any positive reviews. I suppose that some of these products are far less faulty then others.
