Otterbox’s new 2-in-1 Power Bank is yet another device that can be used to charge the Apple Watch should you find yourself without access to a power outlet before it dies, but with a more useful design than other solutions we’ve seen.

It features a magnetic charging mount for the Apple Watch, and with the power bank standing on its end, it can turn the wearable into a bedside alarm clock, using watchOS’ Nightstand Mode for the effect.

Inside is a 3,000 mAh battery that can recharge an Apple Watch up to four full times—more than enough to keep it running during a long weekend excursion—but the power bank can also be used to charge other devices by using its USB-C connection that’s accessible even when the power bank is standing on its end.
