Three-battery pack with four-bay charger

The Kastar BP-820 kit supplies three 7.4 V lithium-ion cells rated at 2050 mAh and a single charger that can replenish four packs simultaneously. It targets videographers using Canon XA and VIXIA camcorders who need extended run-time for long-form shoots.

Fits Canon XA and VIXIA workflows

Each cell replaces the Canon BP-820 or BP-828 and works with the original CG-800 charger, so existing power management stays unchanged. The quadruple dock accepts Micro-USB or USB-C input and includes a Type-C cable, freeing wall outlets and letting operators top up spare batteries while two others power the camera.

Thermals, noise and power draw

The charger draws 5 V at 2–3 A (15 W) and delivers 8.4 V at 800 mA for one or two slots, dropping to 500 mA when three or four cells are seated. An intelligent display shows real-time status and capacity. No active cooling is fitted, so operation stays silent during typical indoor or location use.

Questions about this item

How long can the BP-820 battery run a Canon XA50 before it needs recharging?

Each battery stores 15.2 Wh at 7.4 V and 2050 mAh, so runtime depends on the camcorder's power draw and recording settings.

Does the quadruple charger get loud or hot when all four slots are used continuously?

The charger outputs 8.4 V at 800 mA per slot for one or two batteries and 500 mA for three or four, with no fan mentioned in the specifications.

Which cable or power adapter must I already have to run the charger?

The charger accepts 5 V at 2–3 A via Micro-USB or USB-C; a USB-C cable is included, but the USB power adapter is not supplied.
