I received the dc to dc converter today and it works fantastically for my purpose. I have 5 one foot sections of LED transit coach overhead lighting that runs requires 24 volt input. I want to use these LED's in my camping trailer and that has 12 volts. The converter works perfectly and at 21V output the battery draw is .6 amps and there's no sign of any heat in the leds, the led driver board or the converter. So I'm a happy camper!

OEM Battery Chargers Inexpensive switchmode DC DC converter stabilizes voltage in automotive applications.

OEM Battery Chargers Also can be used to provide regulated voltage in other applications requiring 12 to 24 volt output from 12 to 15 volt input.

OEM Power Supplies Efficiency >50-80%, depending on input, output, and power.


F.Y.I. The converter works just fine with my Canon SELPHY CP900 Black Wireless Color Photo Printer using one of the standard connectors included with your converter and setting the output for 24V. Sincerely, Lewis
