Why it is in the selection

One less separate cable to pack.

A built-in cable can reduce loose items, while making the cable mechanism part of the product you depend on. The 45W figure is a supported-device maximum for USB-C; output is shared when charging multiple devices. Nominal capacity does not equal energy delivered to a phone.

Before choosing

  • Check connector and charging compatibility with your particular devices.
  • Consider the retractable cable’s service options and consult Anker’s current model and recall information before buying.
