Very good little power supply
Excellent. I use it to power a ground station for my UAS. I didn't realize how advantageous the safety features are. I use it with a 3s LiPo battery and it warns me when voltage drops below 11.5v and shuts off when below 10.8. This is important for me, because discharging the batteries too far will destroy them.

NOT a pure sine wave unit
Other local brands with 50% more power for roughly the same price ! ... Plus, this unit is a "step-wave", NOT "pure sine wave" ! ... Wouldn't have bought it, if that fact had been made plain !

BESTEK 300 Watt Power Inverter - excellent design + usefulness
I purchased this power inverter for my son's family to use for camping or in their home - supply power to blow up their air mattress. They tested it and said it works fine. They are very pleased with its size and versatility. The USB ports can be very useful too. Roger Rybarczyk Kalamazoo, Michigan

Works great, easy to use
The product came much early than I expected. It works great! Just plug it into your car adapter spot and plug up your computer or cell phones.

good product
It did what it said it would do. We used it on our 6 hour trip to New York city for our grandsons to watch their video players. And it kept them occupied.
