After introducing Mophie’s juice pack air iPhone 4 case, we found out another similar battery pack case called iPhone 4 juice pack.
Same as the most iPhone battery case, the iPhone 4 case also comes with a rechargeable battery that features 1900mAh capacity. Just as we see, four-LED status indicator is placed on the backing. At the bottom there is a 30-pin connector that allows you to charge or sync your iPhone 4 without removing the case. And the virtual speaker box can simply redirect the sound from the bottom of iPhone 4 to the front.
The iPhone 4 juice pack is priced at $27 USD. Apparently it has an attractive price tag. If you’re interested, jump to USBGeek for more details.
