Mophie Power Capsule | $20 | Amazon

While truly wireless earbuds are relatively limited in terms of battery life, their accompanying wireless charging cases have, perhaps accidentally, become one of their best features. Mophie’s Power Capsule brings those powers to your not-so-truly wireless bluetooth earbuds.

The Power Capsule is a compact, hardshell wireless headphone case with a built-in charging cable and 1,400mAh battery. The case has its charging port and battery indicator lights on the outside, and the case can recharge your earbuds while being charged itself.

Mophie typically sits on the premium end of the external battery spectrum, but today’s $20 deal is a solid $10 less than usual, an all-time low, and beats the hell out of carrying around a case, micro USB cable, and external battery pack.
