2. Setup and Charging
2.1 Initial Charge
Before first use, it is recommended to fully charge the lantern using the USB cable. This ensures the internal rechargeable battery is at optimal capacity.
2.2 Powering Options
The LETMY X2500 lantern offers three distinct methods for power supply:
- Solar Charging: Place the lantern with the solar panel facing direct sunlight. The integrated solar panel will convert solar energy into electrical energy to charge the internal battery.
- USB Rechargeable: Connect the included USB cable to the lantern's charging port and to a standard USB power source (e.g., wall adapter, power bank, computer USB port).
- AA Battery Powered: For extended use or when other charging methods are unavailable, the lantern can be powered by 3x AA batteries. Open the battery compartment located at the bottom of the lantern and insert the batteries according to the polarity indicators. The internal rechargeable battery is used first, followed by the AA batteries.

4. Maintenance and Care
4.1 Cleaning
To clean the lantern, wipe it with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the surface or internal components.
4.2 Storage
When not in use, store the lantern in a cool, dry place. Ensure the lantern is fully collapsed to protect the light-emitting components. If storing for an extended period, it is advisable to fully charge the internal battery every few months to maintain its lifespan.
4.3 Water Resistance
The lantern is water-resistant, making it suitable for outdoor use in various weather conditions. However, it is not designed to be submerged in water. Avoid immersing the lantern to prevent damage.
