With the existing technology at night, before sleeping, the average user puts his mobile device (phone, GPS, PDA) in charge . This happens every night, in every corner of the world. The average night of sleep is about 8 hours but in the meanwhile the mobile phone(as any other modern mobile device, be it PDA, GPS, hand-held console), will be fully charged in less than one hour.
