It has become a fact now that your smartphone battery will hardly even make it through one day, which has made it necessary to keep either an extra battery or a charger with you at all times. The inCharge hopes to make the solution even simpler – all you need with you is your keychain. The inCharge is a small charger with a USB connector on one end that is connected to a microUSB or Lightning connector on the other with an inch-long flat ribbon. When not in use, the two USB connectors can stick to each other due to the embedded magnets, allowing you to add the inCharge to your keychain.
Its price tag is $9, check it out here.
