Battery Charging
Mini can be charged by any 5 V compatible source such as a computer, power bank or charging adapter from a smartphone. Charging follows the standard Li-Po charge cycle that takes approximately 2.5 hours to charge fully. However, after two hours, the device is charged to about 90%. When the device is on the USB and fully charged, the LEDs will turn off.

If you don't want to remove the Mini 4G from your drone, you can connect the Mini to the drone's internal power source and charge it while flying – meaning there is no need to ever detach the device from your drone. If this is your preferred way, please:
Guidelines
- Input: 5 V over USB-C.
- Use a quality USB-A→USB-C or USB-C→USB-C cable.
tip
- Avoid non-compliant or “exotic” fast-charging bricks that don’t provide a normal 5 V fallback. If in doubt, use a basic 5 V charger.
- Don’t use damaged cables or adapters.
