Two BP-820 batteries and a quadruple charger

This pack supplies two lithium-ion BP-820 batteries rated at 7.4 volts and 15.2 watt-hours each, plus a compact charger that can replenish up to four batteries simultaneously. It is aimed at videographers using compatible Canon XA, VIXIA and XF camcorders who need reliable spare power for long shooting days.

Charger fits a USB workflow

The charger accepts 5-volt input through either Micro-USB or USB-C, drawing up to 15 watts, and ships with a USB-C cable. It delivers 8.4 volts at 800 milliamps for one or two cells and 500 milliamps when three or four are mounted, so it can run from common power banks or wall adapters without a dedicated AC brick. Swappable plates let the same unit handle other Canon battery types if required.

Sustained output across multiple cells

Under continuous load the charger maintains its rated current per slot, displaying real-time capacity and status for each battery on its built-in screen. The lithium-ion chemistry supports repeated full cycles without memory effect, keeping output stable during extended recording sessions where all four cells are rotated in sequence.

Questions about this item

How long can one BP-820 battery run a Canon XA30 before it needs recharging?

Each BP-820 cell stores 15.2 Wh at 7.4 V and 2050 mAh; actual runtime depends on the camera's power draw, so plan on carrying a spare for extended shoots.

Does the quadruple charger get hot or noisy when all four bays are active?

The charger delivers 8.4 V at 800 mA per bay for one or two batteries and 500 mA each for three or four; it has no fan, so it runs silently and stays warm rather than hot.

What cables or power bricks must I already own to use the charger out of the box?

A Type-C cable is included; you only need any 5 V USB source that can supply 2–3 A (15 W) such as a standard phone charger or laptop port.
