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

I used this product to blow up an air mattress while on a camping trip. Worked like a charm!

good product fast shipping

Never worked! I bought this to take with my to utilize for charging use and it never decided to turn on or work when I plugged it into my car outlet. Just save your money and look elsewhere

Its small works well so far. I like the switch to turn on/off. I have a small tv and fan and havent overloaded it. Looks well made.

if you use while your engine is not running it might drain your battery in a few hours ,sounds powerful when its on, so you might want to turn off when not in use..its worth it in an emergency...Im able to hook up my boom box when I tail gate ,saves my van speakers from damage..

After reading some of the other reviews about noise level, I was a tad nervous to buy this product, but I decided for the price it was worth the chance. I use a deep cycle battery to provide power to my CPAP machine when we are off the grid. I was looking for something compact and quiet, but powerful enough to run my CPAP machine. This fit the bill perfectly! The only sound I hear is the white noise created by my machine. When testing it with out my machine the noise level was minimal. Great product would buy again!

Great little device to have in your vehicle. You never know when you might need one

Has been working great, however a heat sink made of metal came loose and shorted it out. I took it apart and removed it, been fine since. My son uses it to keep his tablet charged in the back seat and it works well.

excellent product arrived just at the indicated time

Works well. No overheating. It runs a laptop and charges and iPad just fine.
