EKYLIN DC 12v Step up to 24v Converter Regulator 5A 120W Power Supply Adapter for Motor Car Truck Vehicle Boat Solar System etc.(Accept DC9-20V Inputs)

It looks nice.

Installed on a gas Golf Cart (single 12V battery), to power a set of 24V led underglow lights. Easy to install, and works exactly as expected. Quality piece of kit!

I use this to power a 200 Watt load from a 12 VDC supply and this converter doesn't heat up at all, meaning the conversion efficiency is high. This high conversion efficiency should also enable the converter to be mounted inside an enclosure, instead of putting it on the outside as shown in the pictures. The only negative I found it that the leads (wires) are about 4 inches shorter than I needed them to be in putting together my small project. Overall this product at $22 offers good value for your money.

Item arrived quickly and works as advertised

converted 12 volts DC to 24 volts DC for only 1 day, was only to a power a single LED now only output is 12 volts, light does not work with 12 volts
