Save Up to 30% on These Keychain Phone Accessories

Whether you’re a student or a professional, relying on multiple smart devices may also mean you have to carry around different gear to back them up. Chargers and external storage can be frustrating to cart around, but now there's a piece of everyday carry tech gear that makes it easy. The WonderCube Pro is a small keychain with a built-in charger, access for flash storage, and a lot more. You can get one of these all-in-one mobile keyrings on sale for $48.99 (reg. $70), or get two for $84.99 (reg. $118).

This versatile tool packs a lot of essential gadgets into one cubic inch. Forbes called it "Clean, Minimalist, and Timeless," and it's not hard to see why. Keep one on your keys, hanging from the zipper on a bag, or leave one in your car as a backup. Wherever it is, these compact devices are useful for transferring data, refilling your battery, and saving files without an internet connection. Each WonderCube comes with a pair of adapters for Lightning and USB-C devices.

Connect one of the adapters to the foldout Micro-USB to connect your phone, laptop, or tablet. That's one way to transfer data between devices, but you can also connect a microSD card up to 128GB to the WonderCube for fast flash storage.

The WonderCube could even help during a power outage. If you need to charge your phone without an outlet, connect a 9V battery to the top of the WonderCube for up to three hours of talk time. If you need to find your way in the dark, activate the built-in LED flashlight.

You can also use a WonderCube as a phone stand to comfortably stream or join virtual meetings. Attach the micro-suction cups to your phone, prop it up, and enjoy.

Put all your essential iPhone and Android accessories into a cube you can hang on your keys. For a limited time, get the best price online:
