Car phone holders typically offer wireless Qi charging and wired charging. Wired options include USB-C and USB-A ports and sometimes integrated or retractable cables; some models provide both wireless and wired charging options.
Common connections are USB-C and USB-A. Some models also include Micro-USB or built-in/retractable USB-C cables for direct device charging.
Common certifications shown in product listings include UL, CE, and RoHS. Many chargers also advertise protective features such as temperature monitoring and power-management circuitry to help prevent overheating and overloading.
Charging phone holders typically come in several mount styles: air-vent mounts, CD-slot adapters, and suction-cup mounts for dashboard or windshield installation.
Wireless charging mounts commonly deliver around 10 watts. Wired adapters are often in the 17–30 watt range, while multi-port adapters can total up to about 67 watts; some individual USB-C ports are listed at up to 35 watts on certain units.
