Product details
The Mi 37W Dual-Port Car Charger provides two USB-A connections in a compact black body for charging compatible devices during a journey. Its two ports have different capabilities: the red port supports up to 27W, while the standard port supplies 5V at 2A. Together, they provide a stated maximum output of 37W, allowing a driver and passenger to connect separate devices.
Xiaomi describes the red port as suitable for 27W charging on compatible models such as Mi 9 and Redmi K20 Pro. Other devices may charge at a lower rate depending on their supported protocol, battery state and cable. The output rating is a limit rather than a promise that every phone will receive the same power. Select the port and cable that suit the device you want to charge.
The specified input is 12–24V DC at 4A. Check that the vehicle socket provides an appropriate supply and that the charger fits securely. The body measures 74.7 × 30.8 × 30.8mm. Its flexible metal contacts are designed for commonly used vehicle power sockets, while the compact shape helps limit the space taken up beside dashboard or console controls.
A white LED indicates the location of the charging ports, making them easier to find in low light. The body has a frosted surface, with anti-slip side contacts and nickel-plated elements described by Xiaomi. Multiple protective features address overcurrent, short circuits, overvoltage and high temperature, alongside low-EMI technology intended to reduce interference. These features support normal use with a sound socket and suitable charging cables.
The package includes one Mi 37W Dual-Port Car Charger and a user manual. USB charging cables are not listed as included, so use your own suitable USB-A cable for each device. This is a wired charger with no USB-C socket or built-in wireless charging function. Read the supplied guidance, check the connections while parked and keep cables away from controls, pedals and moving parts. Charging performance can vary with the vehicle supply and the devices connected.
