Product Description

The PowerMate DeWalt 20V to 12V Battery Adapter (PMC2001-D) is a portable power supply that converts DeWalt 20V MAX and FLEXVOLT battery power into regulated 12V DC for fuel transfer pumps, sprayers, lighting, and other 12V equipment. Built on a powder-coated steel bracket with a weather shield lip, it's made for truck owners, farmers, contractors, and outdoorsmen who need 12V power in the field without a hardwired install.

The converter delivers a regulated 12V output with 30 amps of peak power and 20 amps continuous, with a built-in on/off switch and integrated fuse for safe, controlled operation. Low battery protection prevents over-discharging your DeWalt battery, and built-in circuit protections guard against overload, over-voltage, overheating, and short circuit conditions. Lever-style quick-connect terminals make hooking up your equipment fast and secure.

Four 130 lb pull-force magnets mount the unit to truck beds, transfer tanks, trailers, and other metal surfaces in seconds, then move it wherever the work goes next. No truck wiring needed — drop in a charged DeWalt battery, flip the switch, and run your equipment anywhere.

Compatible with DeWalt 20V MAX and FLEXVOLT batteries. Battery sold separately. Backed by a 1-year no-questions-asked warranty and a money back guarantee.
