Sharing is caring, folks, and that’s why Samsung has created something that’ll help you share your phone or tablet’s battery life. The company has introduced the power sharing cable, a two-way micro-USB cable that can use power from select Galaxy smartphones and tablets to charge any other device with a microSD charging port. Samsung’s obvious primary use case is charging your Gear S smart watch using your Galaxy S5’s battery, but it should be able to work with any device.
The accessory pairs with an app that will allow you to dictate how much juice is being sent over, so if you only want 25% of your power to be dedicated to charging another device you can make that change quite easily.
The accessory costs a cool $20. That’s a bit much for what’s essentially a male-to-male microUSB cable, but finding a cable with the exact current flow needed for something like this can be hard and the appp is a bonus — some might find that price tag just as fair as any. You can head to Samsung’s site right now to order the cable in white if you’re interested.
