Portable devices like mobile phones and music players are not totally portable as you would routinely need to connect to a wall outlet to recharge its battery. Regardless of how much charge your device can hold, there is no escaping the need to go home and hook it up to a wall outlet.
There has been a few attempts at creating other devices that can provide power to your portable devices while you are away from home. One of these is the solar charger, which can convert the power of the sun into electricity. This is a really good method of charging a device, especially when you are camping or trekking out in the open. A common problem with most solar chargers is when you run out of juice at night. Since there is no sun, you can’t charge your device and would have to wait till morning to charge.
