Mophie Powerstation Keychain Portable Battery REVIEW


The Powerstation Keychain is a miniature power bank that connects to your keychain, belt loop, or bag with a carabiner. It’s a 1200mAh battery that can give your mobile device hours of power in an emergency situation. This power bank is designed for USB-C devices and has a built-in USB-C cable. The cable is hidden beneath the keychain attachment, which saves space on the device. The charger has priority+ charging to provide power to a connected device before the Powerstation recharges itself when it’s connected to a power source. There is a four-light LED indicator that shows how much life is left on the Powerstation. The power bank is available in one color (black) and retails for $39.95 (MSRP).

  • DIMENSIONS: 3.15 x 1.5 x 0.6in (80 x 39 x 15mm)
  • WEIGHT: 2.1oz (60g)
  • WARRANTY: 2-year Warranty
  • IN THE BOX: powerstation keychain / carabiner / quick start guide


The Mophie Powerstation Keychain comes in simple packaging with Mophie branding and an image of the product on the front. It’s noted on the front that there are 4 hours of battery included in the battery and that it’s a USB-C connector. The 4 hours of battery time is estimated for the Samsung Galaxy S9 (3 hours for the Google Pixel 3, 8 hours for the Palm). While I love that it is utilizing USB-C as its main charging method, I do wish that maybe it came with adapters for Lightning charging devices, too. I just think that would make it more versatile for those who use multiple devices.


I really enjoy having a solid, reliable emergency power bank to carry with me everywhere. I do want to stress that this particular power bank is designed to be strictly for emergency use only. It’s not meant to be able to recharge a smartphone 100% so if you need that, you should get a higher capacity portable battery. I really love the size of this power bank and how easy it is to carry around. I would recommend it to anyone looking for a good emergency battery.
