The PowerCell 5 is a dash cam battery pack that keeps a camera recording while the car is parked. It stores 51.2Wh of LiFePO4 energy, recharges while you drive, and adds an LCD, a configurable shutdown timer and USB ports for charging devices. It is small and light at 87 x 160 x 38mm and 0.75kg, so it fits where space is tight. Against the PowerCell 8 it gives up capacity, Bluetooth monitoring and battery expansion, but it keeps onboard controls and USB-C.

Owners rate it well, at 4.6 out of 5 from 34 ratings. They value the steady parked-mode power and the small size, and the main complaints are about capacity and the lack of app monitoring.
The PowerCell 5 is a LiFePO4 battery pack that powers a dash cam while the vehicle is parked. It stores 51.2Wh, recharges while you drive, and has an LCD, a configurable shutdown timer and USB ports for charging compatible devices. It measures 87 × 160 × 38mm and weighs 0.75kg.
The 4,000mAh battery is rated at 12.8V. At a 1.7W camera load it runs about 30 hours, and at 3.2W about 16 hours. These are reference loads, and actual parking time depends on the camera. Extra cameras, cloud connections and devices drawing USB power reduce the time.
The LCD and buttons show battery status and change settings without a phone. The shutdown timer can be set from 1 to 24 hours, and "--" disables it. The timer controls only the dash cam input/output connector, not the USB ports or the whole battery. There is no Bluetooth app.
