Backpack batteries continue to get smaller and less expensive; iKit’s new offering, the NuCharge battery case, is $65 and comes with a handy flip-down kickstand for propping up your iPhone. That they’ve managed to stuff 1400 mAh (which iKit says will double the battery life of the iPhone 4) into the case’s svelte-looking body is pretty impressive.
The case ships in March, but it’s available for pre-order.
