Ouffun Car Charger Splitter 7-in-1 300W — 4-Socket + Dual PD & QC USB with Voltmeter

The Ouffun Cigarette Lighter Splitter is a heavy-duty 7-in-1 car power hub that turns one 12V/24V socket into four switched cigarette-socket outlets plus three fast USB ports with an integrated voltmeter and safety protections.

This compact multi-port adapter is built for vehicles that need reliable, simultaneous power for multiple accessories — dash cams, GPS, mini fridges, heated seats, phone chargers and more. Designed to work in 12V and 24V systems, it offers individual on/off switches and dust covers for each socket, smart USB charging with PD and QC support, and a visible LED voltmeter so you can monitor battery health while on the road.

How many devices can this Ouffun adapter charge at once?

You can power up to seven devices simultaneously: four cigarette-socket devices and three USB-charged devices. The unit intelligently balances output so common accessories and phones charge reliably together without overloading the vehicle circuit.

• Four 12V/24V cigarette-socket outlets with individual switches and dust covers.
• One QC 3.0 USB port (up to 18W) and two PD USB-C ports (30W + 30W).
• Total max output: 180W at 12V or 300W at 24V; single-socket max 120W/12V, 240W/24V.

What fast-charging options does it offer for phones and tablets?

The Ouffun hub includes a Quick Charge 3.0 port plus dual Power Delivery USB-C ports to deliver high-speed charging for modern phones, tablets and USB-C accessories. A built-in smart chip automatically recognizes connected devices and delivers the appropriate current for faster, safer charging.

• QC3.0 USB-A port supports rapid charging for compatible Android devices.
• Dual PD USB-C ports provide up to 30W each for fast phone and tablet charging.
• Automatic current distribution prevents over-current to connected devices.

How does the Ouffun splitter protect my vehicle and devices?

Safety features include a replaceable 15A fuse, over-current and short-circuit protection, and CE/FCC/RoHS certifications. Each socket has its own switch to reduce wear from constant plugging, and dust covers help keep contacts clean when outlets are unused.

• Replaceable 15A safety fuse included with a spare fuse in the package.
• Individual switches reduce unnecessary connection cycles and extend lifespan.
• Dust covers prevent dust and moisture intrusion when sockets are idle.

What does the voltmeter do and why is it useful?

The integrated LED voltmeter shows real-time vehicle battery voltage so you can spot a weak battery before it leaves you stranded. Readings fall within expected ranges for 12V and 24V systems, helping you decide when service or battery replacement is recommended.

• Displays live voltage for quick battery health checks while driving.
• Normal ranges: approx. 11.5–14.9V (12V systems) and 23.1–27.3V (24V systems).
• Main power switch controls all sockets and USB ports for easy shutdown.

Who is this for: The Ouffun Cigarette Lighter Splitter is ideal for drivers who need multiple reliable power sources in a single vehicle — long-haul truckers, camper and RV owners, fleet drivers, ride-share operators, and anyone who runs several 12V accessories at once. It’s particularly suited to heavier vehicles with 24V systems but works equally well in standard 12V cars and vans looking for a durable, feature-rich power hub.
