The iPhone isn’t ideal for watching videos for a long period, it drains battery and is uncomfortable. The iKit Nu Charge’s built-in battery and kickstand fix that.
It gives you 1400 mAh of power that can be switched on when needed. LED lights on the front show you how much power is left too.
The Nu Charge ships in March for $US65 for both Verizon and AT&T iPhone 4. [iKit via Cult of Mac]
