Taidacent24V Transmitting Voltage 12V 3A Output High Power Wireless Inductive Coil Wireless Inductive Modules Wireless Transmitter and Reveiver Power Supply Module (12V3A)

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.

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.

I purchased the 12V 2A long range version. I placed the loops 2 inches apart (I placed the top loop on top of two 2" wide masking tape rolls) as I read on some of these long range ones that you can''t get them too close. So I made sure they were separated.I connected the transmitter to my power supply, and the receiver to a digital variable load. First I thought you feed it 12V so I connected 12V up to it and got almost nothing out. Then saw the description says it will take 48V input. and went up to 30V which was the max of the power supply. I was able to get 12V at about 1.5A out of it at 2" distance. I switched power supplies to one that will go over 30V.. I slowly started ramping up the voltage and got up to about 36V and I heard a pop. The IC on the receiver blew up way before I got anywhere near 40V, never mind 48v. Waste of $40.

It worked even better that advertised. Truly high power and transmitted further than stated. It's great for projects and experiments.

The only thing not permitting me to give it more stars is the fact that it squeals for the first 15 minutes or so of continuous use. I read that either a component on board is not receiving enough power or the power filtering is inadequate. Either way would totally buy more if this slight thing was fixed. Otherwise this thing delivers an unbelievable 3 Ampere over the air! Science magic!

I have an electronic project built in a PVC pipe for waterproofing and needed a method to recharge the batteries ever 6mos. without cutting the unit apart. This wireless charger was perfect. It fits within a flat end cap about a 1/4' thick and couples power just fine.
