Volta fully compatible with new iPod Videos
The 30G has been replaced with a new 30G in the same size case, and the 60G with an 80G again in the same size case. The spacer for the 30G fits the new 30G too, and the 60G and 80G fit Volta without the spacer. The new 30G/80G has a new lower-power video chip that provides for longer video play which is increased from 2 to 3.5 hours, and 3 to 6 hours in the smaller and larger iPods, respectively. The audio play time for the smaller and larger models are unchanged at 14 and 20 hours, respectively.
| Video iPod | Audio play | Audio play w/Volta | Video play | Video play w/Volta |
| 30GB | 14 hours | 64 hours | 2 hours | 9 hours |
| 30GB (new) | 14 hours | 64 hours | 3.5 hours | 16 hours |
| 60GB | 20 hours | 80 hours | 3 hours | 12 hours |
| 80GB (new) | 20 hours | 84 hours | 6 hours | 24 hours |
THE ABOVE NUMBERS ARE AN ESTIMATE.
- Combined with a charged 60GB or 30GB iPod with video, Volta increases the total video play time up to 16 hours.
- Sonnet's Volta rechargeable battery provides an elegant and powerful booster battery solution for iPod with video.
Featuring a slim and sleek design, Volta's case is made from rugged aluminium with a glossy black finish. The iPod simply docks to Volta, which clips to the back of the iPod (a spacer pad is included for the 30GB model). A fully-charged Volta will power the iPod as though connected to a computer or AC adapter. The combined unit stands for easy viewing.
As a complete booster battery solution, Volta includes a charging cable that can be used with any computer, AC adapter, or car charger with a USB port. Additionally, it comes with a detachable belt clip for easy portability. Unlike some other booster battery solutions, Volta is rechargeable. Other highlights of Volta include four LEDs on the front to indicate charging status and remaining charge level.
