Key Features:
- Lightweight and Ultra-Thin: Weighs only 17lb (7.5kg) and is 1.1 inches (2.8cm) thick when folded, making it highly portable.
- Versatile Compatibility: Suitable for most power stations (e.g., Jackery, Goal Zero, Ecoflow) and 12-volt batteries (AGM, LiFePo4, Deep cycle).
- Complete Kit: Includes a smart PWM charging controller with integrated 5V 2A USB ports and various connection cables.
- High Conversion Efficiency: Monocrystalline solar cells maximize power output even in smaller panel sizes.
- Durable Design: Water-resistant construction with a roomy pocket for accessories and a convenient handle for transport.
Setup
Setting up your DOKIO solar panel is a straightforward process. Follow these steps to begin generating power:
- Unfold the Solar Panel: Carefully unfold the solar panel sections on a flat surface in direct sunlight.
- Connect the Charge Controller: The kit includes a detachable PWM charge controller. Connect the solar panel's output cable to the designated input on the controller.
- Connect to Battery or Power Station:
- For 12V Batteries: Use the provided XT60 to Alligator clip cable to connect the controller to your 12V battery terminals (red to positive, black to negative).
- For Power Stations: Use the appropriate DC conversion adapter (8mm, 5.5x2.1mm, 5.5x2.5mm, 3.5x1.35mm, 5.5/6.4) to connect the controller to your power station's input port. If your power station has a built-in MPPT controller, you may not need to use the included PWM controller.
- Position for Optimal Sunlight: Angle the solar panel directly towards the sun for maximum efficiency.

Operating
To maximize the power output from your DOKIO solar panel, consider the following operational guidelines:
- Peak Sunlight: Solar panels perform best when angled directly towards the sun, especially during peak sunlight hours (around noon).
- Uncovered and Shadow-Free: Ensure the panel surface is completely uncovered and free from any shadows, which can significantly reduce efficiency.
- Power Station Input: Be aware that some power stations have a maximum input wattage, which may limit the actual power drawn from the solar panel regardless of the panel's rated output.

Maintenance
Proper maintenance ensures the longevity and efficiency of your solar panel:
- Cleaning: Regularly wipe the solar panel surface with a damp cloth to remove dust, dirt, and debris. Avoid abrasive cleaners or harsh chemicals.
- Storage: When not in use, fold the panel and store it in a dry, cool place away from direct sunlight and extreme temperatures.
- Inspection: Periodically inspect cables and connectors for any signs of wear, damage, or corrosion.

Troubleshooting
If you encounter issues with your DOKIO solar panel, consider the following common problems and solutions:
- Low Power Output:
- Ensure the panel is in direct, unobstructed sunlight.
- Check for dirt or debris on the panel surface and clean it.
- Verify the panel is angled correctly towards the sun.
- Confirm that your power station's input wattage limit is not restricting the power draw.
- No Power Output:
- Check all cable connections to ensure they are secure and correctly plugged in.
- Inspect cables for any visible damage or breaks.
- Ensure the charge controller is functioning correctly (if used).
- Controller Malfunction:
- If the controller is not displaying information or seems unresponsive, ensure it is properly connected to both the solar panel and the battery/power station.
- Check for any signs of physical damage or overheating.
