  • Monitor vehicle battery health via built-in LED voltage display on screen
  • Compact 1.5 x 2.4 inch design weighs only 30g for minimal space
  • Comprehensive safety suite includes short-circuit, over-voltage and over-temperature protection
  • Compatible with 12V and 24V systems for cars, trucks and electric vehicles

Four-port car charger with PD and QC

The RUOCLRIS adapter plugs into a 12 V socket and provides four simultaneous charging ports. It delivers up to 20 W through Power Delivery, 18 W through Quick Charge 3.0 and 12 W through a standard USB 2.4 A port. Phones and tablets can be charged together on a single journey.

LED voltage display and safety protections

A built-in screen shows the vehicle battery voltage in real time for cars, trucks and electric vehicles. The unit includes short-circuit, over-voltage, over-temperature, over-current and under-voltage protection. At 30 g it adds negligible load to the socket.

Total 50 W shared across all ports

The charger’s combined output is limited to 50 W, so four devices drawing maximum power will share that budget. Buyers who need more than 50 W total or dedicated high-wattage ports for multiple laptops should consider a higher-capacity solution.

Questions about this item

How do I install the 4-port car charger and what step do people often miss?

Plug the adapter into the 12 V cigarette-lighter socket until it seats firmly; the step many miss is verifying the LED voltmeter lights up, confirming the vehicle electrical system is live before connecting devices.

What maintenance or replacement will the charger need later?

No user-serviceable parts are inside; keep the ports free of debris and replace the unit only if the LED voltmeter stops displaying voltage or the safety protections trip repeatedly.

What limit appears first when all four ports run at full load for a long time?

The 50 W total power budget caps combined output, so sustained simultaneous charging at 20 W PD, 18 W QC3.0 and 12 W USB will trigger over-temperature protection before individual port limits are reached.
