User Tips
- **First Use Charging:** Always perform a full initial charge for 2-4 hours to ensure the battery is properly conditioned and the flashlight functions optimally.
- **Avoid Fast Chargers:** Stick to a standard 5V=1A charger. Using high-power fast chargers designed for mobile phones can damage the flashlight's internal circuitry and battery.
- **Battery Longevity:** To maximize battery life, avoid completely draining the battery frequently. Recharge when the red indicator light appears.
- **Side Light for Close Work:** Utilize the side light for reading, repairs, or other close-range tasks. This conserves battery life compared to the main beam and provides a softer, more diffused light that is easier on the eyes.
- **Do Not Disassemble:** The battery is built-in and not user-replaceable. Attempting to disassemble the flashlight can void the warranty and cause damage.
