Setup
Initial Charge
Before first use, it is recommended to fully charge the lantern's internal battery. You have two primary charging methods:
- USB Charging: Connect the provided USB cable to the lantern's USB input interface and to a standard USB power source (e.g., wall adapter, computer USB port, power bank). The charging indicator light will illuminate.
- Solar Charging: Place the lantern with the solar panel facing direct sunlight. The solar panel is located on the top of the lantern. Solar charging is slower and best for maintaining charge or for emergency charging when no USB source is available.
Battery Installation (if applicable)
The lantern comes with a removable 18650 lithium battery. If the battery is not pre-installed or needs replacement, follow these steps:
- Open the lid of the battery compartment, typically located at the top or bottom of the lantern.
- Insert the 18650 lithium battery (3.7V / 1200mAh) into the compartment, ensuring correct polarity (+/-).
- Close the lid securely.
