With these solar smartphone chargers, you don't have to worry about your phone running out of power. Crafted out of 100% natural bamboo, the 'iSolar' is energy efficient and eco-friendly.
The iSolar acts as portable battery power and uses solar energy or a computer to charge up to 40% of your iPhone or most other USB-powered devices, such as iPods, androids, tablets and even digital cameras.
When you use the sunlight to charge the iSolar, you simply turn the panel so it is facing the sun. An LED light will show a red charging light and turn green when charging is finished. Charging times vary on sunlight strength, but the device is worth the wait if you are in a bind.
