Ready-to-shoot kit for Canon camcorders

This Kastar kit supplies two 7.4 V lithium-ion batteries rated at 15.2 Wh and a quadruple charger that powers up to four cells at once. It fits Canon XA, VIXIA HF G and XF models that accept BP-820 or BP-828 packs. Videographers who need reliable spare power for long recording sessions will find the set matches the original voltage and chemistry exactly.

15.2 Wh capacity per battery

Each cell delivers 2050 mAh at 7.4 V, giving 15.2 Wh of energy — the single figure that determines how long a compatible camcorder can run between swaps. The charger accepts 5 V input via Micro-USB or Type-C and outputs 8.4 V at up to 800 mA per slot, with an intelligent display that shows charge status and remaining capacity for every bay.

Charges four cells from any 5 V USB source

The compact charger needs only a standard 5 V 2–3 A USB supply and frees you from carrying the original CG-800 brick. Swappable plates let the same unit handle other battery types, so a single charger covers multiple kits. Buyers who need more than two spare packs or who rely on AC-only charging will need additional hardware.

Questions about this item

How long will the 2050mAh capacity last during a typical shoot?

The 7.4V 2050mAh lithium-ion cells store 15.2 Wh each, giving roughly the same run-time as the original Canon BP-820/BP-828 in XA60, XA70 or VIXIA HF G70 bodies.

What does the 8.4V 800mA output mean when I charge four batteries at once?

The charger delivers 800mA per slot for one or two batteries, then drops to 500mA each when three or four are inserted, so a full quad charge takes longer than a single or dual charge.

Will the 3.5×2×2.5 inch charger block adjacent outlets on a power strip?

The compact brick measures 3.5 by 2 by 2.5 inches and plugs directly into a USB-A or Type-C source, so it sits flat without covering neighbouring sockets.
