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

Perfect size. Used to power or charge my laptop, printer, mobile from my cars 12v jack.

Fast charging but its loud

Its so quiet havent had no problems with it.

works great--Im running two small fans off of a 12v battery connection. ran 4 hours today with no problems.

This thing has worked over and over!! We use this to blow up our air mattress. It works every time. Im glad I got it!

Powered a 40 LED TV and a few phone chargers on a power strip at a tailgate with this for 2-3 hours. (Truck has 2 batteries, wouldnt recommend using this too long on a standard car battery)

Nothing bad to say. This was well worth its money in gold

I use this in my work truck to charge a zebra printer, an ipad, and my iphone, it will charge all 3 of them very fast at the same time, it almost feels faster than a wall charger. My truck has a usb port in the dash it takes 15 minutes for the ipad to turn on if it dies, if im plugged into this it almost instantly turns on. I also should note ive had this for 2 years and its still going strong hasnt had any ports stop work and still works as good as the day I got it. This is also relatively quite when its on and doesnt create a lot of heat.

Still working and no problems. Love it
