A discussion about coil alignment on IDT's WP3W-RK wireless power reference kit. There is a positional flexibility that does not require the coils to be perfectly aligned at their center. However, the efficiency of the power transfer will go down as the alignment is offset. At some point, the transmitter will stop transferring power.
