SONRU 7-in-1 Cigarette Lighter Splitter — 3 Sockets + 4 USB, 120W LED Voltage Display

SONRU 7-in-1 Cigarette Lighter Splitter combines three independent 12V/24V cigarette sockets, four fast USB charging ports, independent switches and an LED voltage monitor in a single compact unit for powering multiple car devices safely.

This compact car power hub turns one vehicle cigarette lighter port into a multi-outlet station designed for family trips, rideshare drivers and professionals who need to run or charge several devices at once. It supports 12V and 24V systems, offers built-in safety circuits and a long 2 ft extension cable so passengers can reach ports comfortably. The unit balances convenience with protective features like integrated fuses, temperature-resistant housing and automatic smart charging for USB devices.

How many devices can I run at the same time?

You can connect up to seven devices simultaneously: three via cigarette lighter sockets and four through USB ports. Total limits apply to protect the vehicle electrical system and the splitter.

• Three lighter sockets: each socket supports up to 100W, with a combined maximum of 120W for all sockets.
• Four USB ports: each port supplies up to 2.4A (5V), combined USB output up to 3.6A.
• Use cases: GPS, dash cams, portable vacuum, seat heaters, phones, tablets and small accessories together within rated limits.

How does the voltage display and switches protect my car devices?

The built-in LED voltage display shows the vehicle’s real-time voltage and warns you if voltage drops below safe thresholds. Three independent rocker switches let you turn each lighter socket on or off without unplugging devices, reducing wear and preventing unnecessary draw.

• Digital voltage readout: monitors battery voltage in real time and flashes when below 12V.
• Independent power switches: control each socket individually to stop idle power drains.
• Integrated PPTC 10A fuses and protection circuits for overcurrent, overload and overvoltage defense.

What safety features and build materials does it include?

Safety is addressed through multiple layers: protection circuits, resettable polyfuse elements (PPTC), and a high-temperature-resistant outer shell. These reduce risks of overheating, short circuits and overcharging while maximizing component lifespan.

• Overheat-resistant housing: minimizes temperature-related damage and deformation.
• Multiple protections: overcharge, overcurrent, overload and overvoltage safeguards built in.
• Resettable fuses: PPTC 10A elements protect each circuit and reset after faults clear.

Where should I place this splitter inside my vehicle?

The included 2 ft extension cable gives flexible placement options to reach rear passengers or center consoles. Position it where passengers can easily access USB ports and cigarette sockets without stretching cords across seats.

• Use in center console or rear seating area for passenger convenience.
• Mount near dashboards for dash cams and GPS with short cable runs to reduce clutter.
• Long cable enables placement on back of front seats for rear passengers to charge devices.

Who is this for? The SONRU 7-in-1 Cigarette Lighter Splitter is aimed at drivers and passengers who regularly use multiple electronic accessories in vehicles—families on road trips, rideshare or delivery drivers, and professionals who need reliable, multi-point charging and power. It's suitable for 12V and 24V vehicles and for anyone wanting a safer, more organized way to power cameras, GPS units, small appliances and mobile devices simultaneously while monitoring battery voltage.
