Maintenance
Charging
Regularly charge the device to maintain optimal performance. Use only the provided Micro-USB cable or a compatible alternative. Avoid over-discharging the battery completely, as this can reduce its lifespan.
Cleaning
Wipe the exterior of the flashlight with a soft, damp cloth as needed. Do not use abrasive cleaners or solvents, as these may damage the finish or internal components. Ensure the charging port cover is securely closed to maintain water resistance.
Storage
Store the NEBO Mycro in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, charge the battery to approximately 50% capacity every few months to prevent deep discharge.
