  • Don't buy! Only worked TWICE then nothing
Size: 12V-2000W
Worked great TWICE. After that it wouldn't do anything. Terrible qulaity. Terrible durability. I'm an electrician. I'm VERY careful with connections. I make sure the inverter is turned OFF before connecting cables. I connect the negative first and then the positive. My wires are color coded so I'm CERTAIN to connect them with the right polarity. I will "attempt" to get a refund. We'll see how that goes. ... show more
