1. Safety Warnings
- Please use a 5V/2A charger. Fast charging is not supported and may damage the device.
- Do not look directly into the light beam or shine it into the eyes of others, as this may cause temporary vision impairment.
- When the internal temperature of the bicycle lamp reaches 65 ℃, the lumen output will automatically decrease. This is a normal protective mechanism to prevent battery damage from high temperatures.
- The device is IPX5 waterproof, meaning it is protected against low-pressure water jets from any direction. However, it is not 100% waterproof. Do not submerge it in water or use it for extended periods in heavy rain.
