JOYROOM Car Cigarette Lighter Splitter 9-in-1 210W Adapter — 3 Sockets & 6 USB (PD 36W, QC3.0, LED Voltage Monitor)

The JOYROOM 9-in-1 Cigarette Lighter Splitter is a 210W car power hub that expands one cigarette lighter into three independent sockets plus six fast-charging USB ports, letting you run and charge up to nine devices at once.

Whether you need power for a dash cam, fridge, vacuum, GPS and multiple phones on a road trip or during workdays, this adapter converts a single 12V/24V vehicle outlet into a versatile charging station. Built-in smart chips, QC3.0 and PD fast charging, an LED voltage monitor, and independent socket switches make it a practical addition for families, professionals, and rideshare drivers.

How many devices can I power at the same time and what’s the total output?

You can power up to nine devices simultaneously: three cigarette lighter sockets plus six USB ports. The unit delivers up to 210W total, with single socket power limited to 120W so typical car accessories remain within safe limits.

• 3 cigarette lighter splitter sockets for accessories like fridges or vacuums
• 2 QC3.0 USB ports (18W each), 1 PD USB-C port (36W)
• 3 additional USB ports sharing up to 18W total
• Total combined output: 210W (vehicle dependent)

Will my phone and devices charge quickly and safely?

The JOYROOM adapter supports QC3.0 and PD fast charging protocols, and its intelligent chips automatically allocate current to connected devices. That means compatible phones and tablets get optimized charging speeds while the unit protects against overcurrent and overvoltage.

• PD 36W port for fast charging compatible laptops, tablets, and phones
• Two QC3.0 ports for rapid charging of supported smartphones
• Smart current distribution for simultaneous charging without manual juggling

What safety and monitoring features are included?

This adapter includes multiple built-in protections and real-time battery monitoring to help keep your vehicle electronics safe. A replaceable fuse and official certifications add further assurance for everyday driving and longer trips.

• LED voltage display shows vehicle battery voltage in real time
• Flashing alert if voltage is outside normal ranges (12V: 11.5–14.9V; 24V: 23.1–27.3V)
• Replaceable safety fuse included, plus two spare fuses in the package
• CE, FCC and RoHS certifications for electrical safety and compliance

How does the independent switch design help everyday use?

Each cigarette lighter socket has its own on/off switch so you can leave other accessories plugged in without draining the car battery or wearing out ports. This reduces connector stress and simplifies powering only the devices you need at any moment.

• Three individual switches for precise control of each lighter socket
• Saves wear and tear from constant unplugging
• Helps manage power draw when using high-consumption accessories

Who is this for? The JOYROOM 9-in-1 210W Cigarette Lighter Splitter suits drivers who need a reliable, high-capacity power solution in vehicles with a single cigarette outlet. Ideal users include families on long trips, tradespeople running powered tools or fridges from the car, rideshare and delivery drivers, and anyone who runs multiple electronics simultaneously. The unit's fast-charging USB ports, LED voltage monitoring, replaceable fuses, and independent socket switches make it a practical, safer upgrade for everyday and professional car power needs.
