mophie juice pack reserve micro

Both charging cables tuck neatly into the casing.

Don't be that guy frantically searching for an outlet at the airport so he can recharge his smartphone's battery — or the guy who found one, and now has to huddle close to the outlet, cradling his portable as it slowly recharges. With the mophie juice pack reserve micro, you can have the extra power your smartphone needs always at hand.

The ultra-compact reserve micro is made for on-the-go use. Its USB charging cable folds into the smooth casing, as does the micro USB cable. Just slip the reserve micro into your pocket, handbag, or backpack, and you're ready to go. A built-in LED indicator lets you know the battery's charge status.

Note: Not recommended for use with tablets
