Durable Aluminum Alloy Frame -- The bottom bracket and clamping arms of our car mount wireless charger are made of sturdy aluminum alloy for long-lasting reliability. Auto-Align Smart Charging Cradle -- The Auto-Alignment charging function makes using this car wireless charger a breeze. When it senses your phone, it will automatically lock your phone and adjust to align the charging coil according to your phone size, eliminating the need for manual configuration. Charge Faster with Dual-Coil Technology -- Charge your phone quickly and efficiently with the Dual-Coil 15W Fast Charging wireless car charger mount. With built-in double coils, this charger is more effective than one coil chargers.

We recommend using the ZEEHOO 45W car charger (sold separately) for best results.
