Charging cellphone is no big deal if you're in a place with steady supply of electricity. But there are places on this planet where it is of serious concern given the scarcity of electricity.

You might remember Karaj, a small village in India where its residents have to walk about 20 kilometers just to charge their mobile phones.

The good news is that there are a number of solar chargers developed specifically to answer this concern. One such product comes from G24 Innovations and its lightweight G24i Solar Charger Series, family of solar chargers that work using the power of light (indoors or outdoors) and is initially available in 1/2 watt and 1 watt configurations.

Its product called G5 is created for developing markets and claims to extend talk time up to 15 minutes after an hour of charging. The G10, on the other hand, can double talk time after one hour of charging. Both can also charge other gadgets like MP3 players and digital cameras.

Though I haven't personally tried these products, it simply shows there are now alternatives to electricity that might further extend the use of mobile technology in the far-flung areas.
