The Dometic PLB40 Portable Lithium Battery is a rugged, 40ah battery pack designed to power portable coolboxes, 12v appliances and USB devices when off grid in a drive-away awning or campervan without leisure battery. The PLB 40 Battery is a great alternative for those who do not have a leisure battery fitted in their vehicle or access to 240V hook-up. Provides up to 53 hours of cooling time for a Dometic CFX3 45 Coolbox on a single charge.

Charging status and performance information can be checked via the integrated LCD screen with three convenient recharging options: via the vehicle 12V socket, AC plug socket or via solar panel if you are completely off grid.  

The PLB has an IP44 rating which protects against splashed water from any angle and has protection from under-voltage, over-voltage, short circuiting and overheating for optimum charge time, performance, and storage.
