Mophie, purveyor of popular Juice Pack cases, today announced its offering for the acclaimed HTC One. The case maker is offering the One-specific 2500mAh case for $99.95 in Black at first, with a Silver version to come in "mid-May."

For those who aren't familiar, Mophie manufactures cases that are just a little more special than your average shell – besides protecting your device, they also charge its battery. The cases do this using a special "pass through" port that can be used for data transfer, or charging the case and the device inside (simultaneously, if you're into that).

Though Mophie's claims of the case being "lightweight and low-profile" may be a bit of a stretch, the shell does look quite elegant, if a little puffy surrounding the svelte physique of HTC's all-metal One.

The case also features four small lights indicating its charge level, and a switch that will begin the flow of energy to your dying device. At nearly one hundred dollars, the case isn't a cheap accessory, but if you find yourself going for long periods of time without access to an outlet, it may be a wise investment.
