How to charge your batteries safelyUpdated 2 years ago

Some devices offer on-board charging meaning you can charge the batteries within the device itself. Check to see if your device offers this as some devices have USB inputs purely for firmware updates only, not charging. Attempting to charge through firmware update ports can damage your device. We highly recommend purchasing an external battery charger regardless of whether your device can be charged internally. A dedicated battery charge is not only safer and more convenient but it also extends the life of both your batteries and your device by putting less stress on them.
