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

Used every weekend at an off-grid cabin for 1.5 years, worked great at first, could easily start up and run a 100w fan plus 50w TV, but now cuts out on an 80w load. Fan never kicked on, not sure if that shortened the lifespan. Still not bad for the price.

This converter is great! It will charge 2 wall plugs as well as 2 USB plus. I have charged my cell phone, iPad, camera battery, and laptop all at the same time with no problems. Make sure to keep the unit well ventilated if you are charging 4 devices as it may get hot. Yes, it is loud when it is powered on, but it does not bother me.

Its great, I just wish the cord was a bit longer.

So far so good. Working great , fast shipping. Im a happy camper

Needed this for my spectra breast pump to pump on the go. Works great !

The USB ports on mine stopped working after a couple of years.

Works great.

Great all around so far.

Work well for a 3.5 hours up and 7 hours back, road trip. It was very quiet and hardly noticed it. Then again I was in a softtop Jeep Wrangler. It kept the MacBook charged the entire time and occasionally ran an iPad off it also.

The power inverter works great since I work outside of an office and need tokeep my tablet plugged in, in- between clients, its not loud like my previous one of a different brand. I love it. !!!!!!
