Title: Got a 24V vehicle and want to run 13.8V stuff - this is it!
Review: My humvee is a 24V system (2 ea 12V batteries in series under the passenger (machine gunner) seat.) This makes for smaller wire diameter and easier starting of the diesel engine, but lets face it - everything for cars is 12V!. With this unit, I connect to the 24V battery box, and get 23 amps at 13.8 VDC just like a normal car to run a cigarette lighter socket, 12V - 110 VAC inverter (200W) and other nice things like a stereo.If you have a 24V diesel truck, get this and you will be happy to not screw up your first battery which is the other alternative. If you take 12V from battery #1, then extra current must pass through battery #2 to make up for it, which overcharges #2 and shortens its life, not to mention the power you take from #1 lowers your overall system voltage.It's not that waterproof, so I'd mount it inside the battery box where things stay dry if you ford deep water.
