When not in the sun, the battery can be charged using the AC travel charger or DC car charger.

These great solar backpacks are a great way to solar power all your personal electronics in an environmentally friendly way! Each type of solar powered backpack or solar carry case has multiple options for keeping you running! iPods can be added to the mix with the optional adapter. The three solar panels are tough, light weight, waterproof, and generate up to 4 watts of power. Just plug your standard 12V car lighter cord from your device into the solar backpack and recharge most small electronics including: cell phones, cameras, two way radios, iPods, GPS, PDA's, and MP3s. Note: The Voltaic solar packs are not designed to charge laptops (they require more power). If you don't have a 12V car cord for your device, these solar bags and solar backpacks come with a set of 11 standard adaptors for common cell phones and other devices. Embedded in the outside of the bags are three lightweight, tough, waterproof solar panels which generate up to 4 watts of power. This means quicker charge times! Inside each bag is a Li Ion battery pack which stores any surplus power generated, so it is available when you need it- not just when the sun is up. The battery pack can also be charged using an AC travel charger or car charger (both included). This makes the Voltaic™ solar backpacks and solar bags just as useful on the grid as off. This high quality solar product is ideal for emergencies, travelers, backpackers. Makes a great gift! **Rated as the top Solar Backpack by Wired Magazine (Nov 2005 issue).
