Dash cam battery packs prevent your vehicle’s battery from being drained during parking mode by taking over as the dedicated power source when the engine is off. Instead of pulling power from your car overnight—or for long periods in hot or cold weather—the battery pack supplies clean, isolated energy to the dash cam so your vehicle’s main battery stays healthy and protected.
The Energywell P8 takes that protection even further with massive 12,000mAh capacity, durable LiFePO4 cells (lithium iron phosphate, not lithium ion or lithium polymer) that delivers steady power for up to 96 hours of extended surveillance. LiFePO4 offers superior safety, longer lifespan (more cycles), wider temperature tolerance, and better environmental profile compared to other battery types. Whether you hardwire it to the fuse box or use the cigarette-lighter adapter, installation is simple and built for daily reliability.
A clear front display shows voltage, battery level, and timer settings so you always know how much recording time remains. Dual USB ports plus a 45W Type-C input/output add flexible charging options, and its low-profile design tucks neatly under most seats for a hidden, dependable power setup.
The P8 is expandable! Daisy-chain a second P8 via the optional P8 expansion cable for twice the parking mode duration!
Charge your P8 indoors! Purchase the optional P8 AC adapter to plug in your battery pack at home. This way, if your drive isn't long enough to fully re-charge the P8, you can still achieve maximum charge and protection.
Installation Option #1: Connect the direct-wire cable (included) to the fuse box:
Installation Option #2: Connect the plug-in power cable (included) to the 12v power outlet:
