When a smartphone is placed on the charging plate of the wireless power bank, aA current is induced by the power bank into the phone through the process of electromagnetic induction as explained above. This inductive current is what charges the smartphone.

Qi wireless charging uses the inductive style of charging with the help of charging pads. This is the technology used by Apple as well.

The Lithium-ion battery used in the wireless power bank can y charge quickly with short bursts of energy produced by the placing and lifting of the smartphone on the charging pad.

This makes the wireless power bank a very user-friendly and handy device for all smartphone users.
