This one works the other way round from the step-down converters: it takes your 12V system and makes 24V, up to 7 amps. The reason you would want that is a piece of 24V equipment on a 12V vehicle — a winch, a pump, some marine and commercial gear, certain radios and antennas.

The 9 to 18 volt input window is the useful detail. A vehicle's 12V system is never actually 12V: it sags under cranking load and sits near 14.4V with the alternator working. This converter holds a steady 24V across that whole range, so the 24V device sees clean power whether the engine is running or not.
