Review on Samlex SSW-600-12A: High-Quality 600-watt 12V Pure Sine Wave Inverter by Marty Drury

I deducted a star because they ship cables with this unit that are not rated according to their own instructions. Also because you have to install your own built-in fuse, which is not easy to find. Finally found one the right size (60 amps, but according to the instructions it should be 80 amps) in a radio store hanging on the wall among some other objects (no fuses). I was distracted. I have this plugged in in my car and use it to start my Xbox computer and Q180 via the on screen lockpick. None of the cables overheat, which I believe means there is enough power to meet demand without being overloaded. Be that as it may, so far this little device has performed flawlessly. Pure sine wave is the only option for sensitive electronics. This still has an efficiency of about 85-89 percent. I'd go with a 95 or so, but for the price I'll see how the electronics can handle the unusual performance.
