You can charge older Android smartphones and devices like e-readers and headphones with the BlueBuilt USB-A to Micro USB Cable 1.5m Nylon Black. The cable has an angular micro USB port. New Android smartphones and tablets have an oval USB-C port. You'll only still find a micro USB port on older and more affordable devices. With the 1.5m long cable, you can charge your device near a socket. Choose a longer cable if you want more freedom of movement. This cable is made of nylon and lasts longer than a plastic cable.
