83W Dual-Port Car Charger

The YOUHUA 12V USB charger delivers a maximum combined output of 83W through a 65W Power Delivery USB-C port and an 18W Quick Charge 3.0 USB-A port. It is designed for drivers who need to fast-charge laptops, tablets and phones simultaneously in cars, RVs, boats or motorcycles. An integrated digital voltmeter and button switch provide real-time battery monitoring and power control.

Vehicle Voltage and Port Compatibility

Confirm your vehicle supplies a 12V DC socket before installation. The USB-C port negotiates 15V or 20V for laptops and adjusts to 30W for tablets or 20W for phones automatically. The USB-A port supports Quick Charge 3.0 at 18W. Samsung Galaxy S-series phones are limited to 20W on the USB-C port.

Thermals Noise and Power Draw

The aluminium housing dissipates heat during high-load charging without active cooling, so operation is silent. The intelligent boosting chip manages power conversion from the 12V source up to the 65W peak efficiently. The digital voltmeter displays battery voltage only when the charger is idle or the USB-A port is active, switching to show charging parameters when the USB-C port is in use.

Questions about this item

Does the charger come with any charging cables?

The charger provides a 65W USB-C PD port and an 18W USB-A QC3.0 port for connecting your own cables.

When should I use the 65W USB-C port versus the 18W USB-A port?

Use the USB-C port for laptops needing up to 65W, tablets up to 30W, or phones up to 20W; use the USB-A port for devices compatible with QC3.0 fast charging.

What does the voltmeter show while my laptop is charging from the USB-C port?

While the USB-C port is actively charging a device, the display shows the charging voltage such as 15V or 20V rather than the vehicle battery voltage.
