- Wide Compatibility: Equipped with multiple output ports including 1x standard USB, 1x QC3.0 fast-charging USB (18W max), 1x DC port, and 1x 60W Type-C Power Delivery (PD) port. This makes it ideal for charging power stations, smartphones, tablets, and other USB-powered devices in emergencies or remote locations.
- Smart Charging and High Conversion Efficiency: Features smart chip technology to ensure a safe energy flow through the USB ports, compensating for voltage loss. It also provides overcharge, overheat, and short-circuit protection. The high-efficiency solar cells offer a conversion rate of up to 22%.
- Adjustable Battery Types: Allows setting different charging modes for various battery types: 12.6V for Li-battery, 13.8V for PbAc-battery, and 14.4V for LFP-battery, ensuring optimal and safe charging.
- Portable and Foldable Design: The 120W solar charger is foldable and includes a TPE rubber handle for easy transport. Integrated kickstands allow for a 45° angle setup to maximize energy efficiency. Constructed from durable fabric, robust zippers, and PET material, it is water-resistant and features four eyelets for secure placement.
Setup Instructions
- Unfold the Solar Panel: Carefully unfold the BigBlue 120W solar charger completely.
- Position for Sunlight: Place the solar panel in direct sunlight. Utilize the integrated kickstands to angle the panel at approximately 45 degrees towards the sun for optimal energy capture. Ensure no shadows are cast on the panels.
- Connect Your Device: Locate the control box on the solar panel. Connect your device (power station, smartphone, tablet, etc.) to the appropriate output port (DC, USB, or Type-C PD) using the correct cable.

Maintenance
- Cleaning: Regularly wipe the solar panels with a soft, damp cloth to remove dust, dirt, or debris. Avoid using abrasive materials or harsh chemicals that could scratch the surface.
- Storage: When not in use, fold the solar panel and store it in a dry, cool place away from direct sunlight and extreme temperatures.
- Inspection: Periodically check cables and connectors for any signs of wear, damage, or corrosion. Replace any damaged components immediately.
- Water Resistance: The panel is water-resistant (IPX5), meaning it can withstand splashes of water. However, avoid submerging it in water or exposing it to heavy rain for extended periods. Ensure all ports are dry before connecting devices.
Troubleshooting
- No Charging Output:
- Ensure the solar panel is in direct sunlight and not shaded.
- Check all cable connections to ensure they are secure and correctly inserted.
- Verify that the connected device is compatible with the charger's output specifications.
- If charging a battery, ensure the correct battery type is selected using the Mode Key.
- Check the LED indicators for any abnormal status (all flashing).
- Slow Charging:
- Adjust the panel's angle to face the sun directly (ideally 45 degrees).
- Clean the solar panel surface if it's dirty.
- Cloudy weather or low light conditions will significantly reduce charging speed.
- Ensure the connected device is not drawing more power than the panel can supply under current conditions.
- Device Not Recognized:
- Try a different cable or port.
- Ensure the device is powered on or in a state that allows charging.
