Compatible power kit for Canon VIXIA camcorders

This Kastar kit supplies two 7.4 V lithium-ion batteries rated at 16.3 Wh and a quadruple charger that can replenish four packs at once. The charger accepts Micro-USB or USB-C input and shows individual capacity status on a built-in display. It replaces the original Canon CG-800 charger and BP-809, BP-819 or BP-827 cells for a wide range of VIXIA HF, HF G, HF M, HF S and HG models.

Upgrade from single-bay chargers and OEM cells

If you currently rely on a one-battery charger or a single spare cell, the four-bay design cuts total charging time for a full set. The 2200 mAh packs match the voltage and chemistry of the Canon originals, so runtime per battery stays the same while the extra bay lets you rotate cells during long shoots. The jump is worth it when you regularly drain more than two batteries in a day.

Suits event videographers and multi-camera operators

Videographers who need several charged spares ready at once will benefit from the simultaneous four-slot charging and dual USB inputs. Users who only ever carry one camera and a single spare will not use the extra bays, and buyers needing higher-capacity cells for extended recording sessions should look at larger-capacity alternatives.

Questions about this item

What are the physical dimensions of the included BP-819 batteries?

Each BP-819 battery measures 3.5 by 2 by 2.5 inches and weighs approximately 100 grams, fitting the standard Canon BP-819 battery compartment used in VIXIA HF M300, HF M301 and HF M306 camcorders.

How do I power the quadruple charger and what is the most common setup mistake?

Connect the charger via its Micro-USB or USB-C input to a 5 V 2–3 A (15 W) source; the error users make is plugging into a 1 A phone adapter, which limits the charger to 500 mA per slot instead of the 800 mA single-bay rate.

When should I replace the two 2200 mAh Li-Ion packs and how can I tell?

Replace them when the charger’s capacity indicator shows a noticeable drop from the original 16.3 Wh or when run-time in a VIXIA HF G30 or HF S200 falls well below the initial full-charge duration.
