What this kit powers

This set supplies two 7.4 V lithium-ion batteries rated at 15.2 Wh and 2050 mAh each, plus a dual-slot USB charger. It matches the Canon BP-820 and BP-828 cells used across the XA and VIXIA camcorder lines listed in the compatibility data.

Deciding specification

The charger accepts 5 V 2-3 A input through either Micro-USB or Type-C and delivers 8.4 V at 800 mA per slot, allowing both batteries to charge simultaneously from any standard USB power source.

Thermals noise and power

The charger draws up to 15 W from the USB supply while charging two packs at once. No active cooling is fitted, so operation is silent and the unit stays cool during normal indoor use.
