HURMAI Car Cigarette Lighter Splitter 3-Socket USB-C PD30W with LED Voltage Display and Individual Switches

HURMAI's Cigarette Lighter Splitter turns one vehicle socket into three powered lighter sockets plus three USB outlets, including a PD30W USB-C port and an LED battery voltage readout.

This compact car adapter expands a single 12V/24V cigarette lighter into multiple high-current sockets and USB ports so you can run dash cams, GPS units, mini-fridges, and smartphones simultaneously. Built with individual on/off switches, an overall master switch, and a clear LED voltage display, it balances utility with safety for everyday drivers and professional truckers alike.

How many devices can I power at once and what’s the real output?

The splitter provides three cigarette lighter sockets and three USB ports (including one PD30W USB-C). Total maximum power is 108W on 12V systems and 200W on 24V systems, with single-socket limits matching those totals. Intelligent circuitry manages power distribution so multiple devices can charge or run without unnecessary throttling.

• Supports up to six devices concurrently: 3 lighter sockets + 3 USB ports
• Maximum combined output: 108W (12V) / 200W (24V)
• USB-C port supplies PD30W fast charging for compatible phones

Will this protect my car battery and how does the voltage display help?

The integrated LED voltage display shows live battery voltage so you can spot an unhealthy battery early. The screen doubles as a main power switch and helps you know when your vehicle’s charging system or battery needs attention. Voltage ranges are provided for normal operation to guide monitoring.

• Real-time LED voltage readout for 12V and 24V systems
• 12V normal range: 11.5V–14.9V; 24V normal range: 23.1V–27.3V
• Main switch tied to display for quick power control

How do the individual switches improve convenience and durability?

Each cigarette lighter socket has its own independent on/off switch in addition to a master switch, letting you power only the accessories you need. This reduces wear from constant plugging and unplugging and extends the splitter’s service life. It also prevents accidental drain by leaving nonessential devices off while the vehicle is parked.

• Independent switches for each socket to prevent unnecessary drain
• Master switch to cut power to all ports instantly
• Simplifies device management during travel or overnight stops

What devices work well with this adapter and is it suitable for trucks?

The splitter is engineered to accept a wide range of automotive accessories: dash cams, GPS, in-car refrigerators, inflators, vacuum cleaners, heated seats, and smartphones. Its high power capacity and robust construction make it particularly useful for truck drivers and long-haul vehicles that need multiple powered devices over extended trips.

• Compatible with dash cams, GPS, fridges, pumps, and more
• Designed for both passenger vehicles (12V) and heavy trucks (24V)
• Durable cable and connectors suited for extended use in trucks

Who is this for: The HURMAI Cigarette Lighter Splitter is for drivers who need to power several accessories at once—commuters with multiple gadgets, families on road trips, and professional drivers who require continuous power for navigation, cameras, and comfort devices. If you want a single, organized solution with fast PD charging, battery monitoring, and per-socket control, this adapter is built for practical, on-the-road use.
