The 120W one-vehicle-to-four-vehicles car cigarette lighter expansion device features 4 independent cigarette light sockets combined with 3 PD QC fast charging ports. It is compatible with 12-24V vehicles. It has multiple safety protections for stable voltage output. The long cable can be placed separately and is flexible. It can simultaneously power car electrical appliances and multiple mobile phones. It is a must-have for self-driving and freight transportation.

The device is equipped with 4 standard cigarette lighter sockets, all of which are independently powered and do not interfere with each other. It can simultaneously connect to high-power devices such as vehicle air pumps, vehicle vacuum cleaners, vehicle dash cameras, and vehicle heating pads. It has a wide voltage input range that is compatible with domestic cars, SUVs, light trucks, and vans. During travel, multiple vehicle electrical appliances can operate simultaneously without the need for plugging and unplugging or switching, making it more convenient for travel.This high-power vehicle cigarette lighter extender supports four independent cigarette lighters and is equipped with multiple PD and QC fast charging interfaces. The total power can reach up to 120W, compatible with various passenger cars and trucks ranging from 12 to 24V. It simultaneously meets the power supply needs for vehicle electrical appliances and the fast charging requirements for mobile phones, addressing the pain point of insufficient charging ports in the vehicle.
Four independent cigarette lighters for simultaneous power supply of multiple devices
Three fast charging interfaces for fast phone and tablet charging
The body integrates three fast charging output ports, covering the charging needs of mainstream electronic devices. The PD3.1 fast charging port is compatible with the fast charging protocol of electronic devices and supports high-speed charging for laptops and new mobile phones; the QC3.0 fast charging port is compatible with Android fast charging models, significantly improving charging efficiency; the ordinary USB port provides stable output and is suitable for small-power accessories such as headphones and action cameras. The three interfaces can output simultaneously, and the phones of all passengers can be charged at the same time without competing for power.
High-power stable output with multiple safety protections
The maximum total power of the entire device is 120W. The internal circuit board is equipped with a voltage stabilizing chip, and when the voltage fluctuates during vehicle start-stop, the output is stable and does not damage the equipment. The built-in overvoltage, overcurrent, overheat, and short circuit protection, as well as automatic power-off protection in case of excessive load, eliminate the risk of overloading in the vehicle wiring. The shell is made of high-temperature-resistant flame-retardant material, which does not get hot or deform easily during long-term high-power operation, ensuring safe and reliable use during travel.
Long-line split design, flexible placement in the vehicle
A long connecting line is provided, and the host can be placed in the armrest box or the gap between the seat, without being limited by the original cigarette lighter port position. Passengers in the rear row can also easily access the interface. The integrated one-piece regular shape of the body, with clear button and interface layout, requires no complex operation and is plug-and-play.
All-scenario vehicle compatibility, multi-purpose essential accessory
Suitable for daily commuting, long-distance self-driving trips, and freight vehicle operations. It also caters to the power supply of high-power vehicle electrical appliances and the fast charging of digital devices. The one-to-four multi-hole design combined with multiple protocol fast charging provides a safe and durable expansion of the vehicle's power supply, making it a practical vehicle accessory for solving the shortage of charging ports in the vehicle.
