Review: Saving money saving money - 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.
Review: Works great - 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.

### ⭐ Lights things on fire.
*by A***R on October 23, 2025*

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.
