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

Very convenient and easy to use in the concealed compartment arm rest

I hate going camping with an air mattress that requires a pump because it never fails that it dies or fails to work. But with this gadget, you can take an air mattress that inflates by being plugged in. It worked perfectly. I keep it in the car for everything. Inflated a queen air mattress with no problems.

I have only used this product 4 times in the 2 months ive had it, but its already broken. When it arrived, a screw was missing on the housing but i didnt think anything of it. Today, i went to use it and there is a very loud rattling sound when the fan turns on. it spins, but its loose and hitting things on the inside. Im afraid to leave it running without supervision, it now runs a good chance of overheating because the fan broke. I had high hopes for this and the device worked very well up until the 4th attempted use when i discovered the fan was broken. It sucks because the device was easy to use and i liked the addition of the on/off button and the extra length of the cord. I would have bought another one had the customer service extended their return time past 1 month, but i dont want to buy another one just to have it break again. I have never dropped or done anything to compromise the function of the converter so i have to chalk it up to cheap materials/poor quality control.

Product does what I needed

Excellent power inverter! Holds up and does the job. Its a nice, compact design. I like that it also has USB ports for charging smaller devices at the same time as using a laptop, or something else.

Worked great right out of the box and charged my laptop with no issues.

Excellent product

This power inverter has so many uses. I have a boat with a cigarette lighter, so this gives me the ability to use electronic devices that require a plug, like a tube inflator, phone charger, Bluetooth speaker and so on. I was also thinking that it would be helpful for women on long trips for breast pumps. I would think they would have to either use a manual device or pull over at a rest area and do the pumping in an area that is not so private. The USB drives will come in handy for my kids (and for me). We have 2 USB drives in my car in the front seat that my wife and I use, but the kids are constantly bickering because they want to use those two ports. Now we can plug in the inverter into the cigarette lighter and give them the device in the back seat.

Plugged this into my car’s outlet and turned the switch on. Everything was fine and the green LED lit up. All was well until I plugged in my 87w MacBook charger and the inverter shut off and would not turn back on. Turns out it blew the fuse on my 2013 Honda Civic’s outlet and now I have to replace the fuse. Be careful what you plug into this thing.

The inverter work well but the fan is on all the time so it is a little noisy because I use it in my house
