HURMAI Cigarette Lighter Splitter 4-Socket USB-C Car Adapter — 12V/24V, LED Voltage Display

HURMAI's Cigarette Lighter Splitter is a heavy-duty 4-socket car power adapter with USB-C and LED voltage display that powers up to seven devices in 12V/24V vehicles.

Whether you're driving an SUV for family road trips or piloting a long-haul truck, this HURMAI car adapter expands a single cigarette lighter outlet into multiple powered ports while monitoring battery voltage. Built for high-load situations, it supports both 12V and 24V systems (108W/216W total), includes separate switches for each socket, and offers dust covers and spare fuses for safer, longer service life.

How many devices can I run at once and what power can each port deliver?

The HURMAI splitter supplies three cigarette lighter sockets plus four USB ports so you can charge up to seven devices simultaneously. Total output is 108W on 12V vehicles and 216W on 24V systems; individual socket limits follow those totals, so high-draw appliances should be distributed across ports.

• Three 12V/24V lighter sockets for dash cams, fridges, or pumps
• Four USB ports including USB-C for phones, tablets, and accessories
• Max total 108W at 12V; 216W at 24V (single-socket max aligned to system)

How does the voltage display and switch design protect my vehicle?

This adapter features a real-time LED voltage display that shows your vehicle battery output so you can spot a failing battery early. In addition to a master switch, each lighter socket has its own independent switch to reduce wear from repeated unplugging and to let you cut power to individual devices quickly.

• LED display indicates live battery voltage for 12V and 24V systems
• Main power switch plus separate switches per cigarette socket
• Helps prevent unnecessary battery drain and reduces connector wear

Is this splitter durable enough for trucks and outdoor use?

HURMAI designed the adapter for heavy-duty and mobile environments: each lighter socket includes dust and water-resistant covers to block debris and moisture. The unit also ships with two spare micro-blade fuses to quickly isolate faults and protect both the vehicle electrical system and connected equipment.

• Robust housing suited for trucking, camping, and long drives
• Dust/water-resistant covers on each socket for added protection
• Includes two replacement fuses for quick field repairs
