POTEK 500W Car Power Inverter DC 12V to AC 110V with 2AC outlets and 2A USB Port

I installed it directly onto my center console, and I love having 120v on hand. I load tested it at 450 continuous watts for an hour and it was hot but not as much as I would have thought. My regular use is closer to 200W and it works great at that. Although it is not a true sine wave inverter, it charges/runs things that other inverters don't. Even with the only airflow coming from the built in fan it doesn't get too hot, with a USB fan on it it stays ambient temp. My only complaint is that the manual mentions hardware and a bolt on the unit for a ground but there isn't an easy point to wire in a ground or the hardware to do it.

What a great powerful power inverter. My daughter charged her laptop to finish all of her homework while we were stuck in traffic for 2 hours. What an amazing product. I suggest every get one just in case you need and A/C outlet.

three years later and it's still working fine. using it on a 300 watt fridge, solar setup and its working great

We needed this product for a trip we were taking so that I could sleep in the car, when hubby was driving. I need a CPAP machine while sleeping. It worked perfectly! Make sure you check your individual CPAP machine requirements, but this met our needs.

Priced right for small applications - which is what I was after. I'm only powering two strings of LED lights which draw next to nothing, so this fit the bill perfectly. I am using this in a marine application, mounted in engine room, wired directly to my house battery. The inverter has input fuses (and spares) so I didn't bother adding another fuse or circuit breaker inline. Also of note, this model has 4 cut out tabs which allow you to mount this to a wall, etc. with screws...which is another reason I liked it. I didn't use the provided cables as they were too short for my application, so made up a set of 12ga wires with appropriate ring terminals instead to custom length.

Used for 2 week camping trip and I was able to use all the electronics and more while out in the boonies. It is silent quiet and didnt draw down batteries. I used it for tv and fans and was awesome. When I had to much going it had a clear audible beep to let me know I forgot to turn off water pump or bathroom lights. It made my camping trip 100% better than before I bought it. I am pleased and recommend this for sure. It's the quietest inverter I ever owned, I checked to make sure fan was actually working and it was working because it makes no noise .

I'm using it in my car to power a home theater subwoofer (PL 200ii) it's a 250watt sub/amp. I have it hooked through the cigarette outlet and it sounds great only using 150-180 watts through lighter. You will need longer battery cables to have a permanent setup through battery to get the full power of inverter. You should never use a inverter with your car off. Anything running off the car battery without alternator turning will kill your battery. I cant tell if fan is noisy since its powering a 12inch sub.

Attempted to us it about 2 months after my purchase. Never worked. All 3 fuses we functional (not popped). I tested my cigarette lighter with other gadgets and it worked fine. Plugged this product in... No power...no power light. Disappointed.
