A:Answer This can be used with ALL DEVICES, phones, tablets, watches, headphones and speakers too. The cord that this Charging Tank comes with, "has a USB END" obviously, and the other end fits specifically into The Charger's Tank. So, when you're ready to charge your "specific device", you will "NOT NEED" the Charging Tank Cord at all. You only need "THE CORD FOR YOUR SPECIFIC DEVICE". Since this device has a USB Port, take YOUR DEVICE'S CORD, and plug the USB end into the Charging Tank, and then plug the "specifically designed charging end" of YOUR CORD, into "Your Device" and charge away! The only time the cord for the Charging Tank is needed, is to actually charge the tank itself. This tank has 2 USB Ports so you can actually charge 2 Devices at once! Technology is a beautiful thing. Hope this helps in some way to make your decision. It's a great product with excellent features!
