Fast charger
Style: Qi2 Charging Mount
Simple to install. Holds tightly and has enough adjustment flexibility to get your phone positioned the way you want it. Fast charger and mag holds tightly. Only downside is where to plug in the charging cord. But that would be a problem with any external charger.

charger works, not the adhesive on the ring.
Style: Qi2 Charging Mount
The metal ring adhesive was destroyed by the unit's heat in a few weeks. Do not buy it if you need the adhesive ring to hold the phone. The blinking light ring is annoying - why is it needed.

LOVE this Charger!
Style: Qi2 Charging Mount
This is one of the best chargers I have ever had! My phone stopped charging via the cord and this was my solution and what a awesome one it is! It charges very fast! I also LOVE the way it looks attached to my Tesla screen. Its like having a second screen. I can do Waze on one screen and Tesla navigation on the main screen. I can also control Sirius XM without having to subscribe to it separately for my tesla - which by the way is ridiculous if you already have a subscription…just make sure you done have Allstate DriveWise or other haptics that track weather you’re using your iphone while driving.
