I’m assuming this is wired into the vehicles electrical system via the battery. If so some explanation would be helpful. I guess it comes with instructions, but I think knowing more about how the item works would help others with deciding to purchase it. Like if it is wired to the battery are those connections included, is a fuse included or integrated with the unit, is there an auto off function. The provided information really is very limited. I’d wire it through the acc system myself so it would be regulated with the dash and I only posted this to point out that there isn’t enough detail provided to encourage a purchase.
This item comes with the battery clamps connectors and the cigarette lighter adapter.
