4. Setup
4.1. Battery Installation
The LT1 Q8 is powered by four 18650 Li-Ion button top batteries. For optimal performance and to avoid drawing very high current from a single battery, it is highly recommended to use all four batteries. The lantern can operate with fewer batteries, but this is not recommended for sustained use.
- Unscrew the tail cap of the lantern.
- Insert the 18650 batteries with the positive (+) terminal facing towards the head of the lantern.
- Carefully screw the tail cap back on, ensuring a tight seal to maintain water resistance.
Proper battery installation for the LT1 Q8. Using all four batteries is highly recommended.
4.2. Charging
The LT1 Q8 features a convenient USB-C charging port. It supports 5V 2A fast charging.
- Connect the provided USBA to USBC charging cable to the lantern's USB-C port.
- Connect the other end of the cable to a compatible USB-A power source (e.g., cellphone charger, laptop, power bank, car charger). A 5V adapter is NOT included.
- While charging, the button LED on the lantern will glow red.
- The LED will turn green once the batteries are fully charged.
The lantern can also be operated without batteries directly attached to a USB power adapter, though this is not its primary mode of operation.

7. Troubleshooting

8. User Tips
