In the past mophie was a name that many associated with the iPhone. While mophie has some external battery packs available, a big attraction coming from them are the battery cases and up until a few months back — those were only available for those with an Apple device. That being said, mophie had previously released a battery case for the Galaxy S III and as of today they have announced another for the HTC One.

The HTC One battery case is your standard mophie juice pack. That is to say it is a case with a built-in battery. In the case of the HTC One, that means a 2500 mAh battery. This case is priced at $99.95 and will be available in two colors — black and silver. The one catch here, the silver case is not yet shipping. You can move forward with an order, however the mophie website notes the silver juice pack as being ready to ship in mid-May. Otherwise, the black juice pack is available and will ship out in one to two business days.

Aside from providing an extra 2500 mAh battery for your handset, the juice pack is sporting an LED indicator and a pass-through USB. That basically means you will be able to still sync and charge your HTC One without removing the case. Plus, the juice pack is designed so you can still use the features of the handset which means the speaker, microphone, camera and other features remain accessible.

The juice pack will however add a little extra size and bulk to your handset. In this case, the HTC One juice pack measures in at 2.88 x 6.06 x 0.67 inches and weighs in at 5.05 ounces. For comparison sake, the HTC One by itself measures in at 2.68 x 5.4 x 0.36 inches and weighs in at 5.04 ounces. Simply put, you will be trading the slim design for some extra battery life.
