Charging devices

You can charge your devices using two primary methods depending on the available sunlight:

Charging options: Direct (A) vs Powerbank (B)
Charging options: Direct (A) vs Powerbank (B)
  • Option A (Direct Charging): Connect up to 2 devices directly to the USB ports on the solar charger. This method works best in direct, strong sunlight.
  • Option B (Powerbank Charging): If sunlight is weak or inconsistent, connect a powerbank to the charger. This helps stabilize the charging process. Note: The powerbank must support simultaneous power in/out functionality.
