Gikfun Qi 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.

Installed it on my phone that I broke to retreat retrieve the data that was on it it worked fine unfortunately the screen on the phone was smashed so bad that the phone wasn't of use. Bought the product just to retrieve the information worked great for my purposes.

Same as others have reported I used this in a wireless bento box (3d printer project) it worked great for a couple weeks, started to intermittently charge, then died completely after about a month. It has a flashing blue light but won't charge anything at 3-4mm.

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.

Nicely packaged, very basic setup, and works well. The backplate on the coil is very fragile, so handle it with care. And how long will it last? Nobody knows for sure, but mine is still going strong. It sits on my bedside table, plugged in full time, and charges my iPhone every night. I had some issues with it dropping in and out, but it turned out to be a USB power adapter that wasn't up to snuff. Be sure to use a properly-rated USB adapter! This thing also gets pretty hot while charging (thus the four stars), but so far it hasn't caused a problem.

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……

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.

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.
