SONRU Car Cigarette Lighter Splitter 7-in-1 120W with 3 Sockets, 3 PD USB & LED Voltage Display

SONRU 7-in-1 Cigarette Lighter Splitter consolidates three high-power 12V/24V sockets, three fast USB PD ports, independent on/off switches and a digital voltage readout into one in-car power hub.

Whether you're running dash cams, charging phones, or powering portable devices on the road, this SONRU splitter expands a single vehicle cigarette lighter outlet into multiple, safely managed outputs. Built for cars, trucks and RVs, the unit balances power across sockets, uses smart USB charging, and shows real-time battery voltage so you can monitor electrical health while driving.

How much power can each socket and USB port deliver?

Each cigarette-lighter style socket supports up to 100W, while the combined maximum for all sockets and ports is capped at 120W to prevent overload. The three USB ports are managed by smart charging ICs and share a total USB output that optimizes current for connected devices.

• Per lighter socket: up to 100W (with total device draw not exceeding 120W)
• Combined USB output: smart distribution up to 3.6A across three ports
• USB port nominal: supports 5V/2.4A per port under balanced conditions
• Designed for 12V and 24V vehicle electrical systems

How do the independent switches and voltage display improve reliability?

Each of the three sockets has its own switch so you can power individual devices without unplugging them, reducing wear on plugs and sockets. The built-in LED voltage display reports vehicle battery voltage in real time and flashes a warning if voltage drops below a safe threshold, helping you spot potential electrical issues early.

• Three on/off switches control sockets independently for selective power
• Digital LED shows current voltage and alerts when voltage is low
• Switching reduces plug strain and extends the lifespan of accessories
• Quick visual feedback aids in detecting alternator or battery problems

What safety features protect my devices and vehicle?

SONRU integrates multiple protections into the chassis to shield connected devices and the vehicle’s electrical system. Internal PPTC fuses and safety circuitry guard against overheating, short circuits, overcurrent, overvoltage and other abnormal conditions.

• Built-in PPTC 10A fuses for thermal and overcurrent protection
• Overheat-resistant housing material to improve durability
• Internal circuits defend against overcharging and voltage spikes
• Designed to automatically limit or cut power when unsafe conditions occur

Where can I place the splitter and how easy is it to use?

The unit includes a two-foot extension cable so you can position it within easy reach of passengers or mounted gear. Its plug-and-play design makes installation quick: connect to the vehicle’s cigarette lighter, turn on desired switches, and plug in devices as needed.

• 2 ft extension cable for flexible placement in the cabin or cargo area
• Plug-and-play operation—no tools required
• Compact housing fits into cupholders or seat-back pockets
• Individual switches make it simple to manage power draw for each device

Who is this for? Drivers who need to power multiple devices at once—families on road trips, rideshare drivers, tradespeople, campervan owners, and anyone with several USB or 12V accessories—will find this SONRU splitter useful. It’s aimed at users who want a safe, organized way to expand one vehicle outlet into several dependable charging and powering points while keeping an eye on battery voltage.
