To use a wireless pump to charge your phone, first make sure your phone supports wireless charging. Then, connect the wireless pump to the power supply and make sure the pump is fully charged.
Next, place the phone inside the charging area of the inflator pump, usually a flat surface. Make sure there are no obstacles between the phone and the pump. The pump transmits electricity to the phone through electromagnetic induction to start charging the phone. Wait a while, the phone will be fully charged. Note that wireless charging may be slower than wired charging, so be patient.
