Keychain allows shared charging

The PWR Mate from Pwrwrks allows users to get charge from each other's gadgets.

The creators behind the PWR Mate offer a convenient option for users who are constantly running out of batteries on their mobile devices.

Instead of carrying around a power bank, which most people also tend to forget, the PWR Mate allows the user to supply his electronic gadgets with battery from other people's devices. While chargers are only useful as long as there are outlets nearby, the product can be used anywhere there is a compatible OTG (on-the-go) device.

An OTG function enables USB devices to allow other gadgets to pair with them.

The key ring can be attached to a bag or a water bottle. The hub is encased in high-quality PVC, and the devices can be used simultaneously while charging.
