Blackvue B-130A Ultra Battery - Fast Charging Dash Cam Pack

In this review of the Blackvue B-130A Ultra Battery the bottom line is simple: this is a purpose-built backup power solution for owners of compatible BlackVue dash cams who need long, independent Parking Mode operation without draining their vehicle battery. The reviewer found the unit notable for its fast charging and substantial capacity, delivering up to 30 hours of single-channel Parking Mode runtime and solid protection against vehicle battery depletion. It is aimed squarely at users who want a reliable, dedicated power source for daily drivers or fleet vehicles that remain parked for extended periods.

Key Features

• Exclusive compatibility: Designed specifically for BlackVue dash cams so it integrates cleanly with BlackVue power management and app monitoring.
• High capacity: The 12.8V, 7,500mAh (96Wh) pack supports up to 30 hours of single-channel Parking Mode, which reduces worry during long parking intervals.
• Fast charging: The battery can fully charge in about 50 minutes when hardwired or about 90 minutes via a cigarette lighter, so turnaround between uses is quick.
• Vehicle battery protection: The pack supplies the dash cam independently, preventing the vehicle battery from being drained during Parking Mode or prolonged surveillance.
• Thermal and voltage safeguards: Built-in overheat protection pauses charging and issues audible and visual alerts for over-temperature, high-voltage, low-voltage, and reverse polarity situations.
• Durable construction: LiFePO4 cells and a full aluminum casing improve thermal stability and heat dissipation for lasting, safe performance.

Who It's For

The B-130A is best for BlackVue owners who need dependable Parking Mode recording without hardwiring to the vehicle battery, including owners of two-channel setups who want extended coverage and fleet operators who need predictable, isolated power. It is also useful for people who value quick recharge times so their dash cam is ready between shifts or outings.

Those who should look elsewhere include users with non-BlackVue dash cams, since the pack is designed exclusively for BlackVue compatibility, and buyers who prioritize the absolute lowest cost over integrated features; some customers also found the price and perceived battery life to be drawbacks.
