An unexpected bonus was that this included a very heavy duty 12v socket with battery clamps. I was concerned that this 90 amp converter might stress existing 12v lighter sockets with small gauge wiring. But with this bonus I need not worry about that. I know this will handle the load without setting me on fire.
