with the awesome features of the HTC One such as the front facing stereo speakers, you probably would ran out of juice a little too soon and that’s why there’s the Mophie Juice Pack for HTC One. available in either black or silver for $99.95 each, the Mophie Juice Pack for HTC One’s slim profile packs a 2,500 mAh rechargeable lithium polymer battery which effectively doubles your HTC One usage time. other features include a sleek construction that doesn’t sacrifice the handset’s “zero-gap unibody design”, toggle between charging and standby with a flip of a switch, a set of LED battery indicator to keep you in know of the amount of charge available, and a pass-through USB allows you to charge and sync the HTC One and the juice pack, simultaneously. of course, with the battery case on, you will still have full access to the buttons and ports. you can grab yours off the Mophie web store now.
