Gikfun 20W Qi Charger Module Coil Car Fast Charging DIY Charger Parts Universal Type-C Interface EK1984

Let me start by saying that this was one of the only chargers I could find that accepted just plain power and ground, and claimed it could fast charge, so that's a win right off the bat. So far, it's working great! Works off of 12- 15V, so no need for a buck converter when installed in a car, and fast wireless charges my S23 Ultra. I will update the review with pictures of my setup once it is finalized and 3D printed. This is going into my car in a tight space, so I will see how long it can last in an enclosed, relatively hot space

These actually work on all wireless charging devices so far. I had gotten another charger design/listing that was faster but less compatible. I have encased this one in electronic sealing glue in the garage and it's been good for a couple months. The size is also significantly smaller than the less compatible competing product I mentioned

I'm making custom 3D printer chargers for family and friends. And despite making several modifications to my design, I could never get this to work when it was behind a 2mm sheet of 3D printer PLA. It would do most phones without a cover, but almost none with a cover. Just not enough power or surface. I ended up going with a dual coil charger and it has yet to NOT charge any phone.

it works with my pixel 6 pro. It has 2 leds red for standby and green for charging they are a little too bright but it works well on my 3d printed phone holder

Measurements were accurate, working as hoped. Be aware, tolerance between phone and disk is VRRY small/tight but charging fine.

This is not "Fast Charging" as the listing claims. It is quite slow charging, and it takes my phone hours to recharge. The coil is not powerful enough to wireless charge with anything covering the coil. I wanted to place it behind a thin plastic 2mm to hide it, but it only works if your phone is directly on the coil.

It’s important to understand that this is not a finished product. This product arrives carefully packaged, but with no instructions. You must know what to do with it. Please understand that the second you modify it, no warranty applies. It was perfect for my project. No complaints! This is a power conversion unit. It can light your house on fire if you have no idea what you’re doing. Please don’t blame Amazon.com if you make a mistake.

Installed in car with direct 12V supply connection and the circuit mounted on a heatsink. Charges my phone at about 14W. Zero problems.

I'm impressed by the efficiency at over 15 mm distance from the phone. I am planning on using it as a custom DIY charger on the car, so it will be powered by the car battery at 12-15V

My boss 3d prints charger stands for all are various phones using these as the guts. Newer phones are incompatible with store-bought chargers.

I have 3 different versions of wireless charging coil and this is the only model that will not charge through 1.5mm of light plastic. I used a high power USB carrier with high output cables in all cases and found this charger to not work at all in all cases. Bought a few and it wasn't only one that didn't work as intended. Would buy from Mouser or Digi-Key next time to get higher output, higher quality chargers.

I built this into a custom charge pad. Been working well while the control board is completely closed up.
