Operating Guidelines and Best Practices

SAFETY NOTICE: Do not exceed the continuous 300W load limit. Avoid exposing the unit to direct water, excessive moisture, or temperatures exceeding 40°C.

• First-Time Charge: Fully charge the power bank to 100% before initial deployment to calibrate the internal battery management algorithm.

• Solar Panel Pairing: For solar charging, select a portable solar panel rated between 60W and 100W with an output voltage of 18V–24V DC.

• Storage Care: Store in a cool, dry place and recharge the battery to 60–80% every 3 months during prolonged periods of inactivity to prolong battery cell life.
