Customer Questions & Answers

Customer Reviews

The fan in the unit is a little loud but nothing compared to the old buzz.
dstumpf
An external fuse would not be a bad idea, as changing the internal one could be a pain.
Chris Thompson
Also since it has 2 outlets, I can charge my phone in my car at the same time!

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.
