I am 99% certain I have charged one in the canon charger that came with the camera. However I normally use the Patona yellow and black charger since it takes just about any power source AC/DC/USB-C and the Patona charger has a digital display rather than blinking LEDs

The chargers work

The Canon charger works perfectly well, I have the 2 types of battery and the Canon charger.

Hello,
The Canon charger works perfectly with this battery, and vice versa.
