Abstract

A charging device is provided. The charging device includes a charging box and a power bank. The charging box includes a first battery, a first control module, a wireless charging transmission module, and a first wired charging connection module. The power bank includes a second battery, a second control module, a wireless charging receiving module, and a second wired charging connection module. When the first wired charging connection module is electrically decoupled from the second wired charging connection module, the wireless charging transmission module is capable of delivering power to the wireless charging receiving module.

Claims
