To fully charge your SWEETFULL S2 Rechargeable Portable Fan, expect a charging time of approximately 2.5 hours. Charging is straightforward: simply plug the included USB Type-C cable into the fan and connect the other end to a power source. This can be a wall adapter, laptop, or power bank. While charging, you'll see a green lightning bolt icon illuminated on the display. When the fan is completely charged, this green lightning bolt will turn off. For optimal performance, we recommend charging your SWEETFULL S2 fan fully before its first use.
