SUPERONE 180W 2-Socket Cigarette Lighter Splitter — 20W USB-C PD, Dual QC3.0, LED Voltage Display

SUPERONE 180W 2-socket cigarette lighter splitter provides dual 12V/24V sockets plus a 20W USB-C PD and dual QC3.0 USB ports for powering multiple car devices safely and quickly.

Whether you're running a dash cam, powering a portable fridge, or topping up phones and tablets on a road trip, this compact splitter expands one vehicle cigarette lighter into two high-current outlets and three fast-charge USB ports. Built-in safety features, an LED voltage readout, and independent switches let you control and monitor power use without draining your battery or risking damage to connected equipment.

How much power can this adapter deliver to my devices?

The SUPERONE splitter supports a combined maximum of 180W between the two cigarette lighter sockets and accommodates 12V and 24V vehicle systems. USB charging is handled separately with a total USB current of 7A, including a 20W USB-C PD and two QC3.0 ports for rapid charging.

• Rated input: compatible with 12V and 24V DC systems.
• Maximum cigarette lighter output: up to 180W combined.
• USB output: 5V DC, total 7A across PD and QC ports (PD 20W).
• Replaceable 15A fuse for the lighter plug.

Will it protect my car battery and connected electronics?

Yes — the unit includes multiple protective circuits and a replaceable fuse to guard against overcurrent, overheating, and short circuits. An LED voltage display continuously shows battery voltage and flashes when voltage drops below a safe threshold, giving you a timely warning to avoid deep discharge.

• Built-in overcharge, over-temp, and short-circuit protection.
• Stable plug with a replaceable 15A fuse for easy maintenance.
• UL certification and a protective housing for reliable operation.
• Visual battery-voltage monitoring via LED display; low-voltage flashing alert.

How easy is it to control and install the splitter in my vehicle?

Installation requires nothing more than plugging the unit into your vehicle’s cigarette lighter socket. Each cigarette lighter output has its own on/off switch so you can run one accessory while leaving another off, minimizing standby drain and making operation straightforward while driving.

• Plug-and-play: inserts directly into standard 12V/24V cigarette lighter.
• Independent switches for each cigarette socket for convenient control.
• Compact footprint to minimize interference with other interior controls.
• Replaceable fuse accessible without special tools.

Which devices can I run at the same time without overloading the splitter?

You can simultaneously run high-draw automotive accessories like dash cams, radar detectors, portable refrigerators, and small vacuum cleaners, while charging phones or tablets through the USB ports. Just ensure the total power draw from both lighter sockets does not exceed the 180W combined rating.

• Suitable for dash cams, GPS, radar detectors, heated seat cushions, and mini fridges.
• Fast-charge two phones plus one tablet using PD and dual QC3.0 ports.
• Not designed for heavy appliances that exceed the 180W combined limit.
• Check device wattage to prevent exceeding the rated output.

Who is this for: The SUPERONE 180W splitter is ideal for drivers who need multiple powered devices in the vehicle—commuters, delivery drivers, RV owners, and road-trippers who want reliable sockets and fast USB charging without complex wiring. It suits anyone who wants simple installation, active battery monitoring, and the flexibility to run accessories and USB-powered devices concurrently with built-in safety and warranty coverage.
