Review on POTEK 500W Power Inverter/Car Inverter | DC 12V to AC 110V | Dual AC Charging Port & 2A USB Ports | Laptop & Smart Phone Compatible by Mike Ken

<del>According to the reviews there may be some quality control issues. However, without knowing how many of these they're building per day, it's hard to tell if this is really a problem or if the people who burned it out just caused that 1% to fail. Although I also wonder how many people try to use a power supply that shouldn't even be on. I didn't expect such a job at all. That's what I expected from a small 150W (300W peak power) inverter. You can use the included cable). I will be using it for a TV and a Nintendo Switch laptop/switch this summer and have tested it for many hours with this setup and a 105A deep cycle battery. I let the battery go below 40% and it still worked without any problems, although the voltage dropped to 12.1V. No smoke, the laptop battery never went to 100%, the TV had no power issues, and the unit never overheated. . The only bad thing I have to say is that the fan is pretty loud. The store page boasts that the fan only turns on when it's needed, but it seems to be needed even under the lightest load. The device feels cold and the fan runs at a decent speed. It doesn't matter for my intended use, though, and I'd rather let the device supercool than supercool, even if it costs me a few minutes of overall battery life. This fan doesn't seem to use much power and if I find out that it's dying I can easily install a new fan. </del> Edit: died after almost every use. Most of the work he saw was around 200 watts. It was a very rainy day in the cabin of the boat so it was very humid. I have a feeling it was the cause of death, but it was just moisture, no water ingress. A little disappointed, but for $40 I shouldn't have expected much. So keep dry. Also make sure you have a switch in the supply lines. Before my switch trips, my amp usage meter goes off the charts, but none of the fuses on the inverter actually blow. Curious to see what happens if I just connect it to a battery. The breaker can trip before the fuses blow, but the breaker is 30A and the fuses are 20A.
