SUPERONE car cigarette lighter splitter 180W dual-socket adapter with PD USB‑C, LED voltage display and independent switches

SUPERONE 180W cigarette lighter splitter is a dual-socket car power adapter with PD USB‑C, dual QC 3.0 USB ports, independent switches and an LED voltage display for powering multiple automotive devices safely.

This compact 2-socket adapter expands a single car cigarette lighter into two high-power DC outlets while adding three fast USB charging ports and a real-time battery voltage readout. Designed for both 12V and 24V systems, the SUPERONE splitter supports a combined output suitable for dash cams, portable fridges, GPS units, radar detectors, heated cushions and small vacuum cleaners without overloading the vehicle’s circuit.

How much power can this splitter safely deliver?

The SUPERONE splitter provides up to 180W across its two cigarette lighter sockets and a combined USB output of 7A (including a 20W PD USB‑C and two QC 3.0 USB ports). A replaceable 15A fuse and built-in protective circuitry help prevent overloads and short circuits.

• Maximum rated power: 180W (supports heavy automotive accessories)
• USB output: 5V DC, 7A total; USB‑C PD supports up to 20W
• Replaceable 15A fuse for easy maintenance and protection
• Compatible with both 12V DC and 24V DC vehicle electrical systems

What safety features protect my car and devices?

Safety is built in with protective circuits that guard against overcharge, overheating and short circuits. Each cigarette lighter socket has its own on/off switch so you can control power per device and avoid unnecessary drain on your battery.

• Independent on/off switches for each DC outlet to prevent idle drain
• Overcharge, over-temp and short-circuit protection circuits
• Replaceable 15A fuse inside the plug for added safety and easy replacement
• 18-month warranty for manufacturing and performance confidence

How does the LED voltage display help maintain battery health?

The integrated LED readout shows your vehicle’s battery voltage in real time, making it simple to check battery condition while accessories are connected. If voltage falls below 12V the display flashes to warn you, helping avoid deep discharge and potential starting problems.

• Real-time voltage monitoring displayed on an easy-to-read LED screen
• Flashing warning when voltage drops under 12V to indicate potential battery drain
• Useful for trips, long idling, or when running high-draw devices like refrigerators
• Helps decide when to turn off nonessential accessories to protect battery life

Which devices can I run simultaneously with this adapter?

The SUPERONE splitter is meant for everyday automotive electronics: dash cams, GPS units, radar detectors, small refrigerators, heated seat pads, and cordless vacuums. While it supports multiple devices at once, total combined power must remain within the 180W and 7A USB limits.

• Recommended: dash cam + phone charging + GPS/navigation unit
• Works with car refrigerators and portable coolers (check appliance wattage)
• Suitable for heated cushions and small 12V vacuum cleaners with combined load control
• Not intended to power high-draw items that exceed the rated 180W limit

Who is this for: The SUPERONE 180W cigarette lighter splitter is ideal for drivers who run multiple in-car electronics at once—road trippers, rideshare drivers, van lifers and commuters who need dependable charging, real-time battery monitoring and the flexibility to switch outlets independently. It’s a practical upgrade for any vehicle where space is limited but power needs are growing, offering safety features and a replaceable fuse for long-term use.
