Four batteries and a wall charger

The pack supplies four lithium-ion cells rated at 1900 mAh and 3.85 V each, plus a single AC wall charger with a foldable flat plug. It is intended for owners of GoPro HERO 9, 10, 11 or 12 Black cameras who want spare power for long shoots. The charger accepts 100 to 240 V at 50 or 60 Hz and delivers 4.2 V at 600 mA. An LED shows red while charging and green when the cell is full or on standby.

AC input limits charging speed

The wall adapter draws from standard mains power worldwide but its 600 mA output caps the recharge rate for each 7.3 Wh battery. Users cannot accelerate charging by connecting a higher-current source because the charger has no USB-C or DC-input alternative. The fixed 4.2 V output also means the unit cannot charge other chemistries or larger packs.

Simple swap but no simultaneous slots

Each battery slides into the camera exactly like the original GoPro ADDBD-001, ADBAT-001 or ADDBD-211 cells, so installation requires no tools. The charger holds only one cell at a time, so replenishing all four packs takes several hours in sequence. The foldable plug eases storage but the single bay is the main practical bottleneck.

Not for users needing parallel charging

Photographers who must recharge multiple batteries at once will find the single-slot design too slow. The kit also lacks a car adapter or power-bank input, limiting off-grid flexibility.

Questions about this item

Should I buy the 4-battery pack or a smaller set for my HERO 12 Black?

The pack includes four 1900 mAh batteries and one AC charger, giving you three full spares so you can keep shooting while others recharge.

What does the 7.3 Wh rating mean for actual recording time on a HERO 11?

Each 3.85 V, 1900 mAh cell delivers 7.3 Wh, typically powering a HERO 11 Black for roughly one to two hours depending on resolution and settings.

How fast does the AC wall charger replenish a flat battery?

The charger outputs 4.2 V at 600 mA, so a depleted 1900 mAh pack takes about three to four hours to reach the green-light full-charge indication.
