You may recall we covered the iLuv i604 iPod battery recently. Well, here's another option if you need a battery boost when you're out and about - the TunePower rechargeable battery pack from Belkin.
The TunePower is effectively an extra power source for your player, offering between 8-10 hours of additional playing time, with a power indicator showing his much charge is remaining. The pack comes with three slim-fit protective sleeves, so it'll fit whatever iPod model you have and not cause too much added bulk.
The pack also includes a detachable DC/FireWire cable - used with the Apple AC wall charger or any FireWire port and you can chanrge both player and TunePower simultaneously.
It's available now for around £50.
