SONRU 7-in-1 Cigarette Lighter Splitter — 3-Socket Car Adapter with Dual 36W PD & QC3.0 Fast Charging, LED Voltage Display

SONRU 7-in-1 Cigarette Lighter Splitter is a seven-device car power hub that delivers up to 180W total with three 12V sockets, four fast USB ports including dual PD 36W and QC3.0, independent switches, and an LED voltage monitor.

Designed for drivers who need reliable multi-device power on the road, this adapter converts a single vehicle socket into three cigarette lighter outlets plus four USB ports. It supports both 12V and 24V systems, provides built-in safety features and replaceable fuses, and shows real-time voltage so you can spot low-battery conditions before they cause trouble.

How many devices can I run at the same time and what are the limits?

You can power up to seven devices simultaneously: three devices via full-size cigarette lighter sockets and four via USB. The unit supplies up to 180W total, with single lighter sockets limited to 120W each to protect vehicle circuits.

• 3 cigarette lighter sockets for high-power accessories (maximum 120W per socket)
• 2 USB-C ports: PD up to 36W (one port can reach 45W when conditions allow)
• 2 USB-A ports including one with QC3.0 fast charge support
• Total adapter capacity: 180W (max 192W peak under specified conditions)

What fast-charging options are available and how do they behave together?

The splitter combines USB-C PD and QC3.0 USB-A ports for rapid charging of phones, tablets, laptops, and accessories. Built-in smart chips negotiate power so devices receive optimal current when multiple ports are in use.

• Dual USB-C: each supports PD up to 36W (one port can reach higher peak under single-port use)
• USB-A port supports QC3.0 18W when used alone; USB-A and USB-C share charging limits when used together
• Automatic current distribution for simultaneous fast charging across rear and front passengers

How does the voltage display and independent switching improve safety and convenience?

Three independent switches let you power each cigarette lighter socket on or off without unplugging devices, reducing wear and saving time. The LED digital voltage readout monitors your vehicle battery and flashes a warning when voltage drops below safe thresholds.

• Three rocker switches control each lighter socket separately
• Digital voltage display helps detect low battery before it becomes an issue
• Replaceable 15A spare fuses included for quick protection swaps

What safety features and build quality can I expect?

The adapter uses aluminum alloy and fire-retardant ABS housing with multiple electrical protections. It includes overcurrent, overload, overheating, overvoltage and short-circuit safeguards and is certified by major safety bodies.

• Durable aluminum + ABS construction for heat dissipation and fire resistance
• Built-in and replaceable 15A fuses, plus two spare fuses in the box
• Certifications: UL, CE, FCC and RoHS for peace of mind

Who is this for: drivers who routinely run multiple devices—road-tripping families, rideshare and delivery drivers, RV and truck owners, and anyone who needs fast charging and several high-power outlets in a single compact module. It’s especially useful when you need to power dash cams, portable refrigerators, air pumps, GPS, phones, tablets, and laptops without swapping plugs or overloading a single socket.
