GikfunQi Wireless Charger PCBA Circuit Board Coil Wireless Charging Micro USB Port DIY EK1854

I purchased this charger to use in a phone mount I was making for my vehicle. It was very slim and fit very well inside my design.CAUTION: The alignment of the device you are charging is crucial. On my galaxy s20 ultra there was little margin for error with the alignment. It's just the nature of a small single coil charger like this one.It works great and I intend to buy a few more to make chargers for my other car and desk at work.

The media could not be loaded. I bought this with the intention of sticking it to the phone holder in my car. It starts out with a small current draw, then increases to about an amp. It won’t be the fastest charger I have, but the convenience factor of making my preferred holder wireless……

Needed this to build something for my son. It is quite s all which is good, I can hide it in the build nicely. Wanted to make sure it worked before building in. Plugged the thing into a working port (it does NOT come with a cable) and the red and blue LED's flashed alternately for a moment and settled to a steady red. Put my phone (Galaxy S22) and nothing; would have expected the lights to switch from red to blue. Phone didn't indicate power flow. There was nothing between the coil and the phone! Gave it one star because the lights worked.Think I'll just stick to Chinese food but where are the decent alternatives

Functionally, the charger works well. The circuit is exposed, so you can actually use it to study how a Qi transmitter works, use an oscilloscope to see how the inductor is switched.There should be a stiff flat plate in the package that is slightly wider than the ferrite sheet, otherwise it is inevitable that the ferrite sheet will break. Mine was broken through the middle. It matters very little in terms of electrical performance, but it’s so easy and cheap to fix, I hope the seller reads this and fixes the problem.Do not enclose the little circuit board, it will eventually overheat if you do.

The media could not be loaded. I got two of these to power up a tablet stand I made on the engraver. 1/8" walnut plywood with one of these on the back worked very well.

UPDATE: Product seller sent me a replacement component. Several hours of use in and it seems to be much sturdier than the first one I received. The circuit board is a different design. I would guess a different production company was used for the second component. Changing my review from 1 to 3 stars.The product worked fairly well for about an hour. I knew from the reviews that product durability was a concern and that turned out to be true.Issues:1)The plate the coil sits on looks like a piece of sturdy metal, but it was very brittle and cracked when I attempted to install it into a frame.2) chip set will recognize a charging pad is nearby and connect to it, but will disconnect a few seconds later. It repeats this pattern a few times then stays disconnected but the charging light stays on.3) chip set gets quite warm while charging, could be part of what caused it to fail. It may require a cooling fan to keep from burning out, can't say for sure.It's too bad the transmitter failed, the chip set was easy to design a mount for and fit well into my project.I'd have to recommend against purchasing it, durability just isn't there.

The Gikfun Qi charger matches the picture and description supplied. Specifically the measurements of the charging coil assembly is exactly as described, thus in my case fits as a replacement into another product.Overall the charging assembly (CCA and coil) does work, though I am not planning to use the circuit card.

Surprisingly easy to use. Powers with any USB AC adapter and a micro USB cable. I used it in a wood project I made that can hold my cell phone and now charges it. Just routed out a shallow recess and the placed some thin felt over it to hide it. Did not get hit while charging my phone.
