HTC 10 USB Type-C Cable
The HTC 10 features a brand new charging port on the bottom unlike any other HTC smartphone. Rather than the old traditional micro-USB port on bottom, it features a new USB Type-C port. It's reversible and can be plugged in either direction like an Apple cable, supports extremely fast charging, quick data transfer speeds, and owners can actually recharge other devices with the HTC 10 using a Type-C cable.
It's the port that will be on most smartphones, tablets and other devices in the near future, so get an extra cable for charging in other rooms or the car. All your old micro-USB cables won't work with the HTC 10.
We'd highly recommend getting quality USB Type-C cables, not cheap ones from eBay, Amazon, or gas stations.
