CHARGEKEY – http://goo.gl/zk0NGP
Always have a cable on you.
Chargekey is your Micro USB cable, now the shape of a house key. It’s designed to fit onto your keychain so you’ll always have a Samsung Galaxy cable on you. Use ChargeKey to charge/sync your smartphone from any USB port.
Didn't know Samsung Galaxy phones had a proprietary micro USB connection
Well its a USB3 but you can use just the micro to charge…
No I just find it amusing that they highlight the Samsung Galaxy, I understand its a popular phone but at the same time there are many devices, many that aren't even phones that charge via a micro usb connection.
