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

SONRU 7-in-1 cigarette lighter splitter turns a single car socket into three powered outlets plus four fast USB ports with individual switches and a real-time LED voltage readout.

Keep multiple devices powered on road trips, commutes, or workdays with a compact 12V/24V adapter built for cars, trucks, and SUVs. This unit combines three cigarette lighter sockets (each capable of up to 100W, 120W combined), four smart USB charging ports, and three independent on/off switches so you control which accessories draw power. Safety features and a two-foot cord help place the splitter where passengers can reach it while protecting vehicle electronics.

How does the SONRU splitter let me run several devices at once?

The splitter multiplies one vehicle socket into three cigarette-lighter outputs and four USB ports. Each lighter socket can handle its own device load (up to 100W individually), while the USB ports auto-adjust to connected gadgets for efficient charging.

• Three 12V/24V cigarette-lighter sockets for accessories like vacuums, dash cams, or seat heaters.
• Four USB ports with smart IC, each up to 2.4A (combined USB output up to 3.6A).
• Total permitted output across all connectors capped at 120W to prevent overload.

What safety protections does it include for vehicle electronics?

SONRU designed the adapter with multiple layers of protection to safeguard both the car and connected devices. Built-in fuses and protective circuitry limit risks from abnormal electrical conditions, and the housing uses heat-resistant materials.

• Integrated PPTC 10A fuses and protection circuits for overload/short prevention.
• Protection against overheating, overcurrent, overvoltage, and overcharging.
• Durable, heat-resistant front shell for long-term safety and reliability.

How do the independent switches and LED display improve usability?

Three dedicated switches let you power individual cigarette-lighter sockets without unplugging devices, reducing wear and simplifying control. The LED voltage display monitors vehicle voltage in real time and flashes a warning when voltage is low, helping you spot potential battery or charging issues early.

• One switch per cigarette-lighter socket for selective power control.
• Digital LED display shows real-time voltage and alerts when it drops below safe levels.
• Less frequent plug/unplug extends accessory life and keeps connections tidy.

Where can I place this adapter in my car and who can use it best?

The included 2-foot extension cable lets you position the splitter within easy reach of front or rear passengers. Its size and features make it practical for families, rideshare drivers, contractors, or anyone who needs simultaneous power for multiple devices while on the move.

• 2 FT extension cord for flexible installation and passenger access.
• Compact body fits most center consoles and cup-holder areas.
• Ideal for families, road-trippers, commercial drivers, and mobile workers.

Who is this for: If you regularly use multiple in-car devices — phone/tablet charging, dash cams, portable vacuums, GPS units, seat warmers, or other 12V accessories — the SONRU 7-in-1 splitter gives controlled, protected power expansion. It’s a good option when you need fast USB charging, discrete on/off control for accessories, and a visible way to monitor vehicle voltage without installing hardwired solutions.
