The UGREEN 150W 4-Port GaN Fast Car Charger is designed to charge multiple devices simultaneously in a vehicle. To ensure fast and safe charging, always use a charging cable that matches the rated charging power of your device. The charger features built-in over-temperature protection, which will automatically reduce output power if the internal temperature exceeds the preset safety limit.
Product Overview
The charger consists of a main unit with a back clip and a connector plug. The main unit features three USB-C ports (USB-C1, USB-C2, USB-C3) and one USB-A port. The connector plug includes an LED indicator, a negative pole, and a positive pole for connection to the vehicle's power socket.

How It Works
To use the charger, insert the connector plug into the vehicle's power outlet. Connect your devices (tablets, phones, or laptops) to the appropriate USB ports using compatible charging cables. The charger supports simultaneous charging for multiple devices, with power distribution varying based on the number of devices connected and the specific ports used.
Power Distribution
The total output power of the charger is 150W Max. The power distribution changes dynamically depending on how many ports are in use. For example, single-port charging on USB-C2 can provide up to 140W, while using multiple ports will split the power output between them (e.g., 30W, 90W, 24W configurations). Refer to the power distribution table in the manual for specific wattage outputs per port combination.
