You've got a 24V system in the truck or bus and a load of 12V gear that won't run off it. This converter handles 7A continuous output using switchmode tech, so it's light and compact enough to mount under a seat or in a panel. Plug in from the lighter socket, plug out to your 12V device — no wiring harness rewrite. Input range is 20-30VDC. Jaycar MP3352, RRP $119
