Welcome to this comprehensive guide on how to fix charging issues with your H30i headphones. Encountering a problem when charging your device can be frustrating, but rest assured, this guide is here to help. 

One potential reason is that your charger has insufficient power or damage.

The charging current of the over-ear headphones is quite large, reaching 800mA. The output power of a substandard or broken charger is too low, and the output voltage drops when the charger is connected to a high-current device, keeping the headphones from charging.

Please replace the charger with one that provides sufficient power. We recommend using a quality charger of 5V1A or above.
