SUPERONE 180W Car Cigarette Lighter Splitter — 2-Socket Adapter with USB-C PD & LED Voltage Monitor

The SUPERONE 180W Cigarette Lighter Splitter is a multi-port car power adapter that turns one vehicle socket into two cigarette lighter outlets plus fast USB-C PD and QC USB charging while monitoring battery voltage.

This compact in-car power hub expands a single 12V/24V cigarette lighter socket into two independent 12V accessory ports and three USB charging ports, delivering up to 180W total output. It adds a USB-C Power Delivery port for modern phones and tablets, two QC 3.0 USB-A ports for legacy fast charging, and a built-in LED voltage readout so you can check your battery status at a glance. With independent on/off switches, a replaceable 15A fuse, and protective circuitry, the splitter aims to power multiple automotive accessories safely on road trips, workdays, or daily commutes.

How many devices can I run at once and what’s the power limit?

You can operate two 12V accessories through the cigarette lighter sockets while charging three devices via USB simultaneously, within the unit’s combined power capacity. The adapter supports a total power draw up to 180W (rated 200W peak), and the USB outputs deliver up to 7A combined at 5V.

• Dual 12V cigarette lighter sockets for accessories like dash cams and mini fridges
• One 20W USB-C PD port for phones and tablets
• Two QC 3.0 USB-A ports for fast charging older devices
• Total USB output: 5V, 7A combined; replaceable 15A fuse

Will this damage my car battery or how does the voltage display help?

The integrated LED voltage display continuously shows your vehicle’s battery voltage so you can spot low-voltage conditions early. If the voltage drops below the alarm threshold, the display flashes to warn you, helping prevent deep discharge when many accessories are connected.

• Real-time LED voltage readout for battery monitoring
• Flashing alert when voltage is under safe level (below 12V)
• Helpful for deciding when to stop accessory use to protect battery life

How does the SUPERONE splitter protect my devices?

Safety features include a built-in replaceable 15A fuse, temperature and short-circuit protection, and overcharge prevention across the USB outputs. Those measures reduce risk to both your vehicle’s electrical system and connected devices during heavy use.

• Replaceable 15A fuse for easy field servicing
• Overcurrent, overtemperature, and short-circuit protection circuits
• Independent on/off switches let you isolate accessories without unplugging them

Is it compatible with my vehicle and common accessories?

The adapter works with standard 12V and 24V systems, covering most cars, trucks, and SUVs, and supports a wide range of automotive electronics. From dashcams and GPS units to portable refrigerators and heated cushions, it supplies steady power for multiple devices at once.

• Designed for 12V and 24V DC systems—fits most passenger and commercial vehicles
• Rated power up to 200W (usable continuous output up to 180W)
• Ideal for charging phones, tablets, dash cams, radar detectors, car fridges

Who is this for: The SUPERONE 180W Cigarette Lighter Splitter is aimed at drivers who need to power or charge multiple devices on the road—commuters, road-trippers, tradespeople, and fleet drivers. If you use dash cams, portable refrigerators, GPS units, and modern smartphones simultaneously, this unit gives you flexible sockets, fast USB charging, battery monitoring, and safety features in a compact package.
