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

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.

This charging coil came well packaged with the brittle bits wrapped in thick foam. I had a work colleague help me resolder it as I needed to pass the wires through a hole in the base for my project. He said it was probably silver solder as it had a much higher melt point, if that's worth anything to anyone. I will be encasing this in epoxy as part of my DIY monitor riser for my office. I don't know if the epoxy will hinder the signal at all, but with nothing but air between the phone and the coil, it picks up power about a half an inch away. Lights all work. The only possible concern is that it initially made a high pitched noise when I plugged it in. It hasn't done it again, so maybe it was a faulty cord? Anyway, it works great. Recommended.

I’m currently using this to wirelessly charge my keyboard that has a wireless charging acceptor taped to the bottom. I carved it into some foam and put a mat on top of it and it is able to charge through all of this with no issues. It gets slightly hot but not hot enough to be concerning or start a fire. It’s a good cheap option for DIY projects and works reliably

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.

This thing almost burned my house down. I 3D printed a housing for this to sit on my nightstand, I came home one day and the entire thing was melted into a puddle and smoking. Nothing was charging during this time, or was even CLOSE to the coil. Stay away from this product, unless you want conflagration on your hands.
