Review on QI Wireless Car Charger for Mercedes-Benz C Series: Fast Charging for Smart Phones with Wireless Charging. Includes 2 USB Ports and 1 Type-C USB. by Robert Hole

Installed a charger in our C300 this afternoon. It fits perfectly and has a small 3M sticky pad on the bottom to keep it in place despite being a snug fit. It works as advertised. Yes, the charging pad is slow like most, but it works. The USB-C port will be our port of choice as it is much faster. Just place your phone on the stand and plug in the USB-C connector. It is placed under the console cover. Haven't tried regular USB port yet, but it should work. The small on/off button is easy to miss but works perfectly. Nice addition to a car owned by two non smokers.
