Backup power that goes with you

Keep a little extra charge close at hand. Key Capsule attaches to your keys or bag, making it easy to bring backup power along for your commute, errands, and everyday plans.

Plug in. Keep going.

Unfold the built-in USB-C connector and plug directly into a compatible phone for a power boost without a loose cable. A separate built-in Lightning cable gives you another connection option. Check your device’s charging port to choose the right fit.

  • Charlie M. ★★★★★

    "This little guy is so convenient to carry and throw in my purse. Cute design and quality materials. I have larger ones that have greater capacity but they are so heavy! This one is definitely better for on the go. The ports fit and work great, and it has a quick recharge time. Great quality and value."

  • TheDigital ★★★★★

    "I really like this Portable Charger for iPhone 15 16 Power Bank. It is small and lightweight which makes it very easy to use and carry around. I really like that it has a key change ring attached to it so I can just clip it to anything I'm carrying around. It's fantastic that it comes with both USB-C and lightning cable cords so I can charge any of my devices. It's even better that those cords are built in to it, so I never have to search for a cable. The batter recharges quickly and charges my devices quickly too. It's well made and looks like it will last a long time. I also like that you can the percentage of battery remaining."

With 5000mAh capacity, fast charging, and dual USB-C and Lightning ports, it's a game-changer for my iPhone and other devices. Highly recommend for its convenience, reliability, and portability - a must-have for anyone who's always on the move!"

    "This is the perfect extra charger to take with you. It’s very compact and lightweight. It’ll keep you going until you get somewhere to fully charge. I like that the cables are built in. Also like the ring on top. I got for my granddaughter and she’ll be able to easily attach to her backpack."

FAQ

Which phone models are compatible?

Because of our dual outputs, our power bank will be compatible with most phones! iPhone 15 or newer, as well as other smartphones with USB-C can use the foldable USB-C output. iPhone 14 and older will utilize the lightning output cable.

Why is my power bank providing fewer charges than expected?

There is a 30-40% Energy conversion loss for all power banks when charging. This is normal. Therefore, a 5000 mAh power bank offers ~3500 mAh to power devices.
