6. Litaelo tsa Ts'ebetso
Ho pepesehela Letsatsi ka ho Fetisisa:
The performance of the solar panel is directly dependent on the intensity and angle of sunlight. For best results:
- Place the panel in direct, unobstructed sunlight.
- Adjust the angle of the panel periodically to follow the sun's movement throughout the day.
- Cloudy conditions or indirect sunlight will significantly reduce charging efficiency.
iSolar Technology (for USB Output):
The USB output port features iSolar Technology, which automatically detects the input current of your connected device to provide the fastest possible charging speed. This technology ensures compatibility and efficient charging for a wide range of USB devices.
Laptop Charging (18V DC Output):
The 18V DC output is specifically designed for laptops that require a DC input below 18V/2A. Use the provided DC-to-DC cable and select the correct adapter tip for your laptop model.
