4
4. Low Battery Indication
When the remaining runtime is less than 30 minutes no matter in which output, the
flashlight will flash 3 times every 5 minutes until it is powered off.
5. Charging
When the light is off, open the rubber cap to expose the Micro-USB charging port, plug
the charging cable according to the correct direction, and connect to power source to
charge. It takes about 4 hours to fully charge the device (5V/1A).
Only use batteries with protection circuits.
Make sure the rubber cap is covered well after the charging is finished to not
compromise the IP68 waterproof level.
