The 70mai Dual USB Car Charger provides a reliable way to keep your mobile devices powered while on the road. It features two USB Type-A ports, one of which utilizes Qualcomm Quick Charge 3.0 technology to significantly speed up charging for compatible smartphones by delivering outputs of 5V-3A, 9V-2A, or 12V-1.5A. The second port serves as a standard charger with a 1A output, allowing you to power a secondary accessory simultaneously. Housed in a silver aluminum case, the charger is built for durability and efficient heat dissipation. It operates across a wide input voltage range of 12V-24V, making it suitable for both standard cars and larger vehicles. To ensure your electronics remain safe during use, the device incorporates five integrated protections against common electrical issues such as overcurrent, overvoltage, and short circuits.
