Cigarette Lighter Splitter

SUPERONE Cigarette Lighter Splitter is a dual-socket 180W car power adapter with independent switches, fast USB charging, and a clear LED voltage display to keep devices powered and monitor battery health.

Compact yet powerful, this 2-socket cigarette lighter adapter expands one vehicle outlet into two fully switched sockets plus three fast USB ports, supporting both 12V and 24V systems. It's built to run multiple in-car electronics simultaneously — think dash cams, GPS units, portable refrigerators, and phone chargers — while showing your vehicle’s battery voltage and protecting connected gear with a replaceable fuse and safety circuits.

How much power can I draw from this splitter and what devices will it support?

The SUPERONE splitter delivers up to 180W through its cigarette lighter sockets and a total 7A across the USB outputs (including a 20W PD USB-C and dual QC 3.0 USB-A). That combination is suitable for most common automotive accessories and charging needs without overloading a single socket.

• Rated power up to 180W for cigarette lighter sockets; works on 12V and 24V vehicles.
• USB: 5V DC, combined 7A output — includes 20W PD USB-C for faster phone charging.
• Ideal for dash cams, GPS units, radar detectors, car fridges, heated cushions, and small vacuums.
• Replaceable 15A fuse protects against overloads and short circuits.

How does the LED voltage display protect my car battery?

The built-in LED voltage readout continuously shows your vehicle battery voltage so you can spot drops before they become a real problem. If voltage falls below 12V the display flashes to warn you, helping prevent deep discharge and avoid starting issues.

• Real-time voltage monitoring visible while the splitter is plugged in.
• Flashing alert when voltage drops under 12V to prompt action.
• Helps you avoid battery drainage from prolonged accessory use when engine is off.
• Useful during camping, long idling, or accessory-heavy trips.

What safety features and protections are included?

Safety is layered into the design: a stable cigarette plug, protective circuits, and a replaceable 15A fuse help shield both the splitter and your devices. The unit includes safeguards against overcharging, overheating and short circuits to reduce risk during everyday use.

• Replaceable 15A fuse inside the plug for overload protection.
• Built-in protective circuitry for over-voltage, over-current, and short-circuit events.
• Independent on/off switches for each lighter socket to prevent unnecessary drain.
• 18-month warranty for added owner confidence in durability and support.

How easy is it to install and use in different vehicles?

Installation is plug-and-play: insert into your vehicle’s cigarette lighter/receptacle and start using instantly — no wiring needed. Because it supports both 12V and 24V systems, the splitter works in cars, trucks and many commercial vehicles without modification.

• Quick plug-in operation — no tools or wiring required.
• Compatible with 12V and 24V electrical systems (rated power 200W listed for safety margin).
• Independent switches let you power only the sockets you need to save battery life.
• Compact footprint fits most center consoles and dashboard sockets easily.

Who is this for: drivers who run multiple accessories or rely on constant device power — such as rideshare and delivery drivers, RV owners, long-distance commuters, and anyone who needs reliable in-car charging. If you want to expand one cigarette lighter outlet into a multi-port power station with battery monitoring and protective features, the SUPERONE 180W 2-Socket Cigarette Lighter Splitter is a practical, user-friendly solution.
