VFENE QI Fast DIY 5W/ 7.5W/ 10W Wireless Charging Transmitter, Wireless Charging Module, Wireless Charging PCBA (Micro USB)

I've tried several different bare chargers and they all have similar issues, namely they have to be positioned very precisely to work and have to be very close to the phone (i.e. no thick cases). What makes the problem worse is that they all have a wire running over the top of the coil, which creates more distance between the coil and the phone. So when I saw this one with the wire routed behind the coil, it was worth paying twice the price for that extra millimeter.Unfortunately, this is not what they shipped me. The one I got is like all the others, with the wire on top of the coil. And even worse, this one is the most finicky I've tried yet. It takes much more effort to get it positioned to start charging than any other charger I've used.It's totally pointless to have a wireless charger that's harder to use than a regular wired charger.

I have been working with this charger for just over a month.....too bad that I did not react sooner as I could have returned the product. I agree with the others that the alignment has to be very exact for it to work. Even when you get everything aligned as it should, charging begins, and then sometime during the charger cycle causes it to stop charging. The alignment has not changed, but it is no longer charging. Very frustrating when you charge your devices at night for the next day only to wake up and find your day is not starting off right. If you can babysit this device, this may work for you. If you need a device you can have confidence in, this is not it.

The advertise show 5/7.5/10w but It charge Samsung S9 the same that a 5w charger..
