It discharges the battery without being overloaded and if you connect a 200w battery charger, it burns the fuse in the adapter. Terrible product.

Useless thing, it can't even handle a 280-watt resistance. The most useless purchase I've made, if it had a negative star rating, I would give it 1000, and that's saying something..

Unfortunately, after 3 months it broke down, with only a 15W load, while its features and the ones it provides are excellent. What a pity.

I use it on an olive harvester generator mainly for a 12v sheep shearing machine. It doesn't output the watts it claims, but it is satisfactory. It cannot power a refrigerator, maybe it behaves differently with a 12-volt battery. It has many automations and protections. It also comes with a small wheel and a separate drill.

I come back, it's not worth the money, it stopped working, it burned out and I threw it away. What a waste of money... If you see the internal wires that come out of the sockets, they can't handle more than 10 watts. After a few days, I come back on 30-05-2020... this specific inverter was repaired by me because I am an electronics expert. For anyone interested, the damage was caused by a burned diode 1N4148 next to the MT-3205 transistor. You replace it and everything is fine... but if you don't know, don't bother.

Very good, I have worked with it quite a bit and with both sockets at the same time.. it makes a little noise compared to another one I had but it doesn't bother me.. everything is ok.
