Inverter, best "deal" i've found

Junk.

Typical cheapo Chinese import.

That is a MSW inverter, side of the pix says 220V and 1500W and it is supposed to be 3000W at 120V..

Most likely it is a bunch of misleading typos and I think that it is 300W at 120V, not 3000W..

I think you will sorely be disappointed..

All that unit will be good for is to waste your money.

Instead of trying to find the "best" price for the most watts, perhaps think QUALITY MANUFACTURER first..

Cheap price does not equal quality..

Otherwise if you want returnable cheap, at least go to Harbor Freight, with them at least you know that if it burns up you can get another..

Just going by looks, the cables are similar to what i have for a 300 watt inverter. So probably 10 gauge at best.

The dc cable supplied doesn't look as if it could do 300 amps, at least not without a LOT of voltage drop.

Inexpensive modified sine wave inverters are not difficult to find.
I choose not to use modified sine wave inverters. Your choice...is your’s.
