5 and 2 Watt solar panels to charge a USB power bank
 
Use the solar panel (5 Watt -16 x 21 cm & 2 Watt - 9.5 x 16 cm) to charge a USB power bank when the sun is shining. The power bank is always topped up and ready to charge a phone when required.
 
The 5 watt solar panel can charge power banks at a rate of 500 mAh when placed in full sunshine. For example, charging a 5000 mAh power bank will take approximately 10 hours. The 2 Watt solar will take more than double this time to charge the power pack.
 
The solar panel can also be used to charge other USB devices like LED and bicycle lights.
