Features:S1050 solar charger uses the power of the sun to charge two triple AAA NIMH rechargeable batteries, in just 6 hour on a sunny day. The thin portable chargers just need a sunny or shady spot to go to work!Sleek and slim, the S1050 solar charger fits on a window sill. Once the batteries are charged, the S1050 will work anywhere to charge your devices. The unit is glass free and durable.Temperature doesn't affect the charger. Solar chargers do not lose performance when the temperature exceeds 77°F (25° C) as under actual outdoor operating conditions. In sunny situations, it will charge a MP3 player in 2.5 hours (See chart for additional charging times).The solar conductor is constructed by depositing extremely thin layers on flexible stainless steel substrate. Typically the panel is 1 millimeter thick.The charger is exceptionally durable and is strengthened by being encapsulated in UV stabilized polymers. Glass-Free solar chargers protect solar cells by DuPont polymer films instead of fragile glass.Utilizing thin film triple junction high voltage technology, this solar charger has 3 times higher shadow tolerance than conventional solar technology to help the unit charge in cloudy or shady conditionsShipping & cost:Will ship UPS GND, FDX GND, FDX Home delivery, postal service.
