Made from recycled bottles the Voltaic solar bags are mobile solar power generators designed to charge virtually all handheld electronics.
The Voltaic Backpack is built tough for use as a weekend hike bag or as a large daypack. There are pockets and wire channels for multiple electronic devices and 1,850 cubic inches of storage space.
MADE FROM RECYCLED BOTTLES
Voltaic bags use fabrics made from recycled PET i.e. soda bottles. We worked extensively with suppliers to develop these fabrics, since they were not previously available. Recycled PET fabric is light weight, extremely durable, UV resistant and water resistant. It even looks better than the nylon it replaced. Most importantly, it uses significantly less energy to produce and creates demand for recycled materials.
Note: It is not designed to charge laptops, it will however charge cell phones, sat phones, PDAs, GPSs, iPods, cameras and most other handheld electronics
How long does it take to charge a device?
If the battery pack is already full, a typical cell phone will charge in about the same time it takes using a car charger (roughly 2 hours, although it varies by phone). The ideal way to use this product is to keep the battery pack charged, so that the charge is available when needed.
The actual time in the sun required to fully charge a typical cell phone is 4-6 hours. This will increase in cloudy weather, or if the panels are not angled towards the sun. The following table shows the typical time in the sun required to charge different devices. These are estimates and will vary based on the battery power of those devices.
| Approximate Charging Times | |
| Item | Hours Direct Sunlight * |
| Voltaic Battery Pack | 8-10 |
| Cell Phone | 4-6 |
| Digital Camera | 4-8 |
| GPS | 4-6 |
| iPod | 5-6 |
| * Charge times may be increased in cloudy weather, high temperatures, or where panels are not angled towards the sun. | |
