"The Redarc BCDC dual-input battery charger allows for easy charging of a DC battery while you're on the move. Most battery chargers require that you plug into an AC outlet, but this DC-to-DC charger pulls power from your vehicle's start battery instead"
Talk about unclear on the concept...
If it works as is described it would help to nullify the ridiculous ECU controlled charging systems.
BUT, it would have to be ignition controlled to neuter effects when the alternator is not charging the chassis battery.
As far as TT is concerned, this device cannot manufacture watts.
