Dewalt Compatible 18V to 12V Step Down Power Supply
PRODUCT DETAILS
Note: We do not recommend using dual battery adaptors for longer run time as they can damage your battery. You should never combine two batteries at different charge levels.
The JMM Solutions Volt Step Down Power Supply effortlessly converts your 18-20V tool battery into a versatile 5V-13V via an anderson connector with up to 10 amps of power.
Perfect for powering a variety of 12V devices like car fridges, LED lights, fans, phone chargers, water pumps, and other camping or vehicle accessories. It’s an essential companion for off-grid adventures or worksites.
Featuring a clear voltage display and built-in protections against low voltage, overcurrent, and short circuits, it ensures reliable and safe operation.
Fridge Runtime
On average, a fridge draws around 1 amp per hour. Using a 12Ah battery, you can expect approximately 12 hours of runtime under typical conditions.
Actual runtime will vary, with ambient air temperature being the biggest factor—hotter conditions cause the fridge to cycle more often, reducing overall runtime.
