1500W? At 12V that's 125A - That is fucking dangerous! Most sockets are rated at 20A. Most inverters that are >300W use crocodile clips, or preferably screw-down terminal rings. The cable looks way too thin too. That's a fire waiting to happen....
Haha! I reported it to ebay. Man that was a faff, there's no category to report dangerous / lying listings. The chat system was crap too. I had to say "I want to speak to a human", and it put me through.
