I wired my own up using a 3 amp fuse, I think hooked up a amp clamp and the draw for 2 was around 1 amp when running. Not hard to open these up and make your own with a new battery. Is the fuse in the power supply or internalize can't remember seing one on the one I cut apart. But mine is ran off 2 car batteries could run them for days.
