Belkin jumped on the iPod battery extender bandwagon on Monday with the release of its TunePower for third and fourth generation iPod and iPod mini players.
Priced at $79.99, the rechargeable battery pack allows for 8-10 hours of additional play time and is available at major retailers.
The add-on features a 2-cell lithium ion battery that fits in one of three sleeves--10/15/20GB iPod; 30/40GB iPod; or iPod mini.
You can charge your iPod with the TunePower add-on simultaneously with the Apple AC wall charger included with your iPod or through a FireWire port from your PC.
There is also a power-level indicator so you can monitor when batteries are low.
The gadget comes in white or silver and features a protective case to prevent dirt, dust, or impact from damaging the connector.
