  • TypeAutomobile Chargers
  • 30 W total output charges two devices at once
  • USB-C Power Delivery 3.0 fast-charges compatible phones
  • USB-A Quick Charge 3.0 fast-charges compatible phones
  • LED display shows car-battery voltage within ±0.2 V

Dual-port car charger with voltage display

This 30W adapter plugs into a cigarette-lighter socket and provides one USB-C port with Power Delivery 3.0 and one USB-A port with Quick Charge 3.0. It charges two devices simultaneously and shows the vehicle battery voltage on a bright LED readout accurate to within 0.2V. The compact housing fits flush in most 12V outlets for a clean installation.

30W shared output and real-time battery monitoring

The combined 30W budget handles a phone and a tablet at the same time, with the USB-C port delivering up to the full 30W when used alone. Voltage monitoring lets you spot a weak alternator or ageing battery before it leaves you stranded. Protection circuits guard against over-heat, over-current and over-charging on both ports.

PD 3.0 and QC 3.0 limits in a 12V system

Power Delivery 3.0 and Quick Charge 3.0 negotiate the highest voltage each device accepts, but the 12V vehicle supply caps the total at 30W. Devices that require higher wattage profiles will fall back to standard charging speeds. The LED display draws negligible current and remains readable in daylight without distracting the driver.
