HURMAI Car Cigarette Lighter Splitter 4-Socket + 3-USB PD30W — 108W/216W Multi-Outlet Adapter with LED Voltage Display

The HURMAI Cigarette Lighter Splitter is a heavy-duty car power hub that converts one vehicle socket into four cigarette lighter outlets plus three USB ports, delivering up to 108W (12V) or 216W (24V) and PD30W fast charging for multiple devices at once.

Designed for long drives, commercial vehicles, and tech-heavy commutes, this compact adapter combines multiple power outputs, individual switches, and an LED voltage readout so you can run dash cams, GPS units, portable fridges, phones, and tablets without overloading a single outlet. Built with dustproof covers, spare fuses, and UL certification, it prioritizes safety and durability for demanding road use.

How can this adapter power several devices simultaneously?

The HURMAI splitter provides four cigarette lighter sockets and three USB ports that together support high total wattage—up to 108W on 12V systems and 216W on 24V systems—so you can operate multiple high-draw devices at once. Each output is controlled independently, preventing unnecessary drain or interference between devices.

• 4 cigarette lighter sockets for accessories like fridges or heated seats
• 3 USB ports including PD30W for fast phone/tablet charging
• Total power: 108W (12V) / 216W (24V)
• Supports running up to 7 devices simultaneously

What safety and control features protect my vehicle and gear?

Safety is built in with individual on/off switches for each port plus a master switch so you can isolate or disable outputs without unplugging devices. The unit includes two spare micro-blade fuses and dustproof/water-resistant covers for each socket, reducing contamination and short-circuit risk in rough conditions.

• Individual switches for selective power control
• LED voltage display to monitor battery health in real time
• Dustproof and water-resistant socket covers to keep contacts clean
• Two replacement fuses included for added protection

Which devices charge fastest with this car adapter?

The PD30W USB Power Delivery port delivers significantly faster charging than standard 20W USB chargers, making it ideal for modern smartphones and tablets that support PD. The remaining USB ports and cigarette sockets supply stable current to dash cams, GPS units, coolers, and other in-vehicle electronics without throttling.

• PD30W for rapid smartphone/tablet charging
• USB ports compatible with iPhone, Samsung, Motorola, LG, and more
• High-power sockets suitable for dash cams, car fridges, heated seats
• Balanced distribution minimizes slowdowns when multiple items run

How do I monitor and avoid draining my vehicle battery?

The integrated LED voltage readout shows your vehicle’s battery voltage in real time, helping you spot low-voltage conditions before they cause starting issues. When voltage approaches the programmed thresholds, you can quickly cut power to nonessential loads using the unit’s switches to conserve battery life.

• Real-time voltage display for 12V and 24V systems
• Easy power cutoff with master and individual switches
• Prevents accidental overnight battery drain from plugged devices
• Useful for monitoring alternator performance on long hauls

Who is this for: The HURMAI Cigarette Lighter Splitter is ideal for truck drivers, RV owners, taxi and rideshare drivers, and any commuter who uses several powered devices in a vehicle. It’s also a good choice for outdoor adventurers who run portable fridges or for families on long road trips who need to charge phones, tablets, and entertainment devices simultaneously. If you require a robust, controllable, and safe way to expand a single vehicle socket into multiple high-capacity outputs, this adapter delivers professional-grade performance and peace of mind.
