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

The SONRU 7-in-1 cigarette lighter splitter is a multi-port 180W car power hub that lets you run three lighter sockets plus four USB outputs (including dual PD and QC fast-charge ports) while monitoring vehicle voltage.

Take control of power in any 12V or 24V vehicle with a compact, metal-reinforced adapter that splits a single cigarette lighter into three high-power sockets and four smart USB ports. Designed for road trips, work trucks, and daily commutes, this unit balances simultaneous loads, warns you when battery voltage drops, and lets you switch individual lighter sockets on or off without unplugging devices.

How can this splitter power multiple devices at once?

The SONRU adapter combines three cigarette-lighter sockets and four USB ports into a single unit with a 180W total output (max 192W momentary). Its onboard power-management distributes current to prevent any single socket from exceeding safe limits, so cams, refrigerators, and vacuums can all run together.

• Three independent 12V/24V lighter sockets for high-draw accessories (single socket limited).
• Two USB‑C PD ports (36W each) for tablets and laptops.
• Two USB‑A ports including QC3.0 support for fast-phone charging.
• Smart chip balances simultaneous charging across ports.

What fast-charging options does it offer for phones and laptops?

This splitter integrates modern USB standards: dual USB-C PD ports rated up to 36W and a QC3.0‑capable USB‑A port. The system detects device needs and allocates current so phones, tablets, and small laptops receive optimized voltage and speed when possible.

• Dual USB‑C PD outputs (each up to 36W) for rapid PD charging.
• USB‑A with Quick Charge 3.0 when used alone; shared chip adjusts output when ports are combined.
• Automatic device recognition for safer, faster charge delivery.

How does the LED voltage display and switching improve safety?

SONRU includes an LED panel that continually shows vehicle voltage and flashes a warning if levels drop below safe thresholds. Three dedicated on/off switches let you isolate each lighter socket, preventing unnecessary drain and avoiding repeated unplugging of bulky accessories.

• Real-time LED voltage readout to monitor battery health while running accessories.
• Digital warning flash when voltage falls under 12V to prompt attention.
• Independent mechanical switches for each lighter socket to reduce wear and conserve power.

What protections and build quality does it provide?

The adapter is constructed from aluminum alloy and fire-rated ABS, with replaceable 15A fuses and a suite of internal protections. It’s certified to common safety standards and includes spare fuses and mounting accessories for secure installation.

• Replaceable 15A fuses (two spares included) for overcurrent protection.
• Overheat, overload, overvoltage and short-circuit safeguards built in.
• UL, CE, FCC and RoHS certifications and a metal-reinforced housing for durability.

Who is this for? The SONRU 7-in-1 lighter splitter is made for drivers who need reliable, simultaneous power in vehicles — from contractors and RV travelers to families on road trips. If you run dash cams, portable fridges, inflators, laptops, or multiple phones in a 12V/24V vehicle and want easy switching, voltage monitoring, and fast USB charging without constant plugging and unplugging, this unit simplifies power management while helping protect your vehicle’s electrical system.
