Supplied with blown fuses. Sending an electric shock through anything associated with spare fuses! What's more, it only lasted a day before not even being able to handle a 200-watt load. Garbage and the potentially life-threatening electrical current it sends through devices. So weird and out of place. I immediately replaced my tried and tested inverter. There is no electric shock, the noise in the speaker has disappeared. I order another brand 1200w with remote switch. Worth the money for this junk.
