Description

A power bank for wireless charging of portable devices

technical field

The utility model relates to the technical field of charging equipment, in particular to a power bank for wireless charging of portable equipment.

Background technique

Wireless charging technology (Wireless charging technology; Wireless charge technology), originated from wireless power transmission technology. Wireless charging, also known as inductive charging, non-contact inductive charging, uses near-field induction, that is, inductive coupling, to transmit energy from a power supply device (charger) to a device that uses electricity, and the device uses the received energy to The battery is charged and simultaneously used for its own operation. Since energy is transmitted between the charger and the power-consuming device through inductive coupling, there is no need for wires to connect the two, so that both the charger and the power-consuming device can have no exposed conductive contacts.

However, most of the current wireless charging devices are too expensive, and some are slightly lower in price but of poor quality. This problem needs to be solved urgently.
