Emission coil and receive coil distance for 1 ~ 20 mm, if small current work can be appropriately increase receiving coil turns to increase transmission distance

Test data, for reference: Emission coil: copper wire diameter φ 0.6 mm, coil diameter 40 mm, around 20 turns. Receiving coil is same. Emission coil grafted in 12V power supply: standby working current300 ma, load is 4.2V 800mAH polymer lithium battery

If receiving distance increase it's need to add the coil turns. In ractical application, it can change the turns of coil to adjust the power.

Many possible apllications.
