The USB Car Charger is a high-efficiency step-down voltage converter (buck converter) designed to charge and reliably power up to four devices simultaneously, delivering a total combined current of up to 4 A.
This charger is highly beneficial for family road trips, rideshare and taxi drivers, and anyone who needs to reliably power a large number of portable devices on the go.
Key Features:
- Highly stable output voltage regardless of load fluctuations;
- Uncompromising safety ensured by multiple protective circuits, including thermal shutdown (overheat protection) and overcurrent protection. Certain configurations are also equipped with a built-in fuse and reverse polarity protection;
- Simultaneous charging for up to four devices.
Connection and Usage
The device connects directly to the vehicle’s standard 12V/24V accessory power outlet using a heavy-duty cigarette lighter plug. Devices (such as smartphones, tablets, and GPS navigators) are connected via the four available standard USB Type-A ports. The total combined current draw of all connected devices should not exceed 4 A for continuous operation.
