The VIOFO BP100 is a 98Wh LiFePO4 battery pack that charges while you drive and powers a compatible dash cam when parked. It includes hardwire and cigarette-lighter charging cables plus a Type-C camera cable for supported VIOFO models. Bluetooth lets you check its status from your phone, and you can add EP100 expansion batteries for longer parking runtime. It suits drivers who want a separate parking-power reserve instead of draining the car battery, though quoted runtime depends on the camera and recording mode.

Rated 4.5 out of 5 from 54 ratings, owners generally report the BP100 does what it promises for parking power. Complaints center on real-world runtime falling short of the headline figure and on installation effort.
The VIOFO BP100 is a dash cam battery pack that stores power while you drive and supplies a compatible dash cam while the car is parked. It uses a 98Wh LiFePO4 battery and gives the camera a separate power reserve for parking recording. Bluetooth battery monitoring is available through the VIOFO app, and EP100 expansion batteries can be added.
Runtime depends on the camera and recording mode. VIOFO rates the pack at approximately 32 hours with a single dash cam drawing 3W. Additional camera channels, different recording settings and a device charging from USB change the load and runtime. The camera still needs a suitable parking mode, memory card and settings.
The pack charges through the fuse box with the hardwire cable or through a vehicle socket with the cigarette-lighter cable. A full charge takes approximately 70 minutes by hardwire, or around 100 minutes through the cigarette-lighter input. The ACC signal tells the pack when the vehicle is off, and a socket that stays live can continue supplying power. Follow the BP100 manual for the constant-power, ACC and ground connections.
