The Mophie Juice Pack for the HTC One manages to be an external battery pack and a protective case – and a surprisingly form-fitting one, at that. There’s a slight bulge at the back for the battery, of course, but it’s nothing that’s going to take up too much pocket space. That battery is 2500 mAh, and will double the current battery life of the HTC One. There’s an LED indicator on the case for the life of the external battery, and the case lets NFC and Bluetooth signals pass through it.
The case only adds 5.05 ounces in weight to the HTC One. External charging can be turned on or off with the flick of a switch. If you’re a new HTC One owner, and need your phone to actually last the day, the Mophie Juice Pack looks like a pretty good deal. You can get one now for about $100. It comes in black and silver.
