BESTEK 300W Power Inverter DC 12V to 110V AC Car Inverter with 4.2A Dual USB Car Adapter

Worked Great with a 12V Car Battery. This is a good solution for a power outage.

I had my first one of these for about a year before it was stolen when my car got towed. I just went online and bought another one because theyre extremely useful and when it arrived, I noticed several improvements even though I thought I was buying the exact same model for the same price. This unit is robust and durable and build entirely of metal. Its sturdy and had high quality switches and cable. Both USB outlets are higher powered now while one can be lower powered if needed. This is a fantastic buy and I would recommend to everyone.

The inverter is great ,the power plug is slightly over sized and is very difficult to get into the outlet far enough to make contact

Cord left much to be sidereal everything else works awesome....

Purchased in May 2020. Used few times to charge laptop in car. October 2020, inverter stopped working.

Didn’t work for what I needed.

Working good

As expected

The fan runs fairly consistently in my car. The noise is slightly less than when the air is turned on to a medium fan speed in the car. You may only be able to get one transformer into the two outlets because of the size of the transformer. Tried to charge my Nook HD+ directly off the 2.1A port and it didnt work, but it did with the Nook charger off the outlets. Not sure why.

A typical cheap modified sine wave inverter. It doesnt run electric fans very well (they make a lot of noise), nor does it power LED lightbulbs well. The LED lights come on but noticeably dimmer than wall power. The fan runs on high speed all the time regardless of load. It sounds like a Shop Vac. Mine died after 18 months powering a HEPA filter (70W) in my car. One day it just stopped working.
