This is a demo test of the pair of wireless power charger, five LEDs connected paralleled on the receiver end, output more than 200~300 mA (over range of display) current. There are some more notes:
- We use a very thin plastic bag to separated the receiver and transmitter, the thickness of the plastic bag is probably only 0.1mm.
- The magnetic ring of transmitter and receiver get the best transmission performance when the fully matched in round shape, and the power transfer lost very very fast when distance increase.
- The board can transfer on receiver 5V/200-300mA power, check this on the current meter.
- Power bench on the transmitter end is 0.3A and 6V (1.8W).
Update: Get a high power transfer pair, can transfer up to 1.3A current on very close distance. Easily drive small motors, or similar items!
