Taidacent 12V 3A High Power Long Distance Inductive Charging Wireless Charging Module Wireless Power Supply Module (12V3A Long Distance)

I love it thanks

I have an antique secretary desk that we use as an accent piece for the sitting room. We display some small art pieces and knick-knacks in it so I wanted to add an LED light source but didn’t want to drill holes to run power through it. These let me send power through the cabinet to operate some low power LEDs without permanently altering this beautiful antique. Would also be perfect for applications where air or water tightness are important.

2 out of 4 are not working. Try to contact the seller but no reply.

This will transfer power wirelessly over a small distance. How much power depends on the distance. How much voltage is distance dependent too. As can be seen in the video, the power level changes with respect to the distance. The LED bulb brightens and dims depending on how far the coils are apart. This is not a conclusive test as the LED globe is low wattage 12V and runs down to about 3 Volts. It will transfer full power over about 7mm air gap, but you also need to factor a case that protects the coils. If you only need a few volts and a few watts, this will transmit over a good distance. Well over an inch with usable power for small projects. That is however physics. Applications for this abound. Waterproof electronics behind a bulkhead on a boat come to mind for me. My sample was well made, professional looking and had good layout. It is caseless so you can install it. I'm worried about the heatsink. They really need to have that mounted on the board and not rely on the component leads for mechanical support. I know they were thinking give as much flexibility as possible to the user, but this imho is an oversight. Too easy to damage and novice users will mess it up easily.

This product works exactly the way it was made. But, I had to go to YouTube, to figure out how to hook it up, and properly use it. It does a good job in what I use it for.
