The Dometic PLB40 Ah Lithium Iron Phosphate battery delivers high levels of mobile power - up to 40 hours of Dometic CFX 40W cooling on a single charge. Designed for powering powered coolers and other 12 V appliances while being off-grid. Thanks to its lightweight and compact design you can enjoy true independence and travel off-grid for longer.

From smartphones to powered coolers - and anything in between: The power of the Dometic PLB40 is supplied by integrated lithium iron phosphate (LiFePO4) battery cells. Engineered for use in harsh outdoor environments, its rugged design will keep your gear charged and ready even on the harshest expeditions. Lightweight, with a ergonomically designed stainless steel handle, the PLB40 is easy to carry, while an integrated DC-DC charger offers three convenient ways to charge via: the vehicle 12 V DC socket, solar panel or AC home power. The user-friendly, integrated LCD display provides important information on performance including: the battery capacity, charging/discharging status and output status.

Tough design marked with IP44 rating: Popular Dometic products like the CFX3 35 and 75DZ compressor coolers and the PLB 40 battery pack are marked with an IP44 rating. IP stands for Ingress Protection, which considers the extent to which a product is protected against penetration by solid and liquid particles. An IP44 rating verifies that the product has been tested and proved to have effective protection against solid objects larger than 1 mm, such as tools and small wires, as well as against splash water from any angle. In other words, your Dometic CFX3 compressor cooler, and the PLB 40 portable power pack, are splash-proof and therefore fit for the rigors of outdoor use.
