Stop juggling spare battery packs and slow hand-pump grease guns. The Groz Rechargeable Battery Grease Gun (47380, model RGG/12L) keeps the power source inside the tool — a 2000mAh lithium-ion battery built into the handle, recharged through a standard USB-C cable. One tool, one cable, no separate battery slide-pack to lose or replace.A 12V motor drives output up to 3 oz (87 g) per minute and develops 8000 PSI (550 bar), giving you steady delivery for chassis fittings, pivot pins, U-joints, bushings, mower spindles, trailer hubs, and other zerks across automotive, agricultural, and shop equipment. The aluminum die-cast head includes an air release valve to purge trapped air, and the powder-coated barrel resists scuffs and shop wear.A full charge runs through about seven 14 oz (400 g) cartridges, and recharge time is roughly 1.5 hours. The grease gun ships complete with a 30 in (750 mm) high-pressure hose with spring guard, a 3-jaw hydraulic coupler, and the USB-C charging cable. Filling options include 14 oz cartridges or 500 cm3 bulk loading, making the 47380 a practical fit for everyday maintenance in garages, fleet shops, farms, and home workshops.
