HURMAI 12V Socket Power Outlet Car Power Hub 10FT Cable — 4× 12V Sockets, USB‑C PD30W & LED Display

HURMAI's 12V Socket Power Outlet is a multi-port vehicle power hub that delivers up to 216W (24V) or 108W (12V) through four 12V sockets plus Type-C PD30W and QC3.0 USB ports, all on a 10-foot heavy-duty cable for flexible installation.

Designed to expand and manage in-vehicle power, this adapter converts a single cigarette-lighter input into four independent 12V outlets while adding fast-charging USB-C and USB-A ports. It combines a smart IC for safe charging, a clear LED voltage display to monitor battery condition at a glance, and a master on/off switch to prevent unnecessary drain when parked. Included accessories (spare fuses, stickers, and a manual) and UL-certified components make it suitable for everyday driving, work vehicles, and outdoor setups.

How does this adapter keep multiple devices powered without overloading the vehicle?

The HURMAI hub uses a built-in smart IC that balances output among connected devices and cuts excessive draw to help prevent short circuits. It supports a combined USB output maximum of 48W and total socket outputs of 108W (12V) or 216W (24V), so medium- to high-power units can run safely when within those limits.

• Smart IC chip for regulated charging and short-circuit protection
• USB-C PD30W + QC3.0 18W for fast device charging
• Four 12V sockets with dust covers for simultaneous connection
• Maximum combined power: 108W (12V) / 216W (24V)

How do I install the 10-foot cable and eyelet terminals safely?

Installation is straightforward: the heavy-duty 10-foot cable uses color-coded leads—red for positive and black for negative—and pure copper eyelet terminals sized for solid ring-mount connections. Always confirm polarity and the vehicle’s voltage before attaching, and use the included fuses to protect circuits.

• 10-foot reinforced cable for flexible placement and remote devices
• Pure copper eyelet connectors (8.4mm inner diameter) for secure bolting
• Color-coded wiring: red (+) and black (-) to prevent reversal
• Two 15A spare fuses included for circuit protection

What does the LED display and master switch show and control?

The built-in LED panel reports real-time voltage so you can monitor battery status visually and see alerts if voltage is abnormal. The master switch lets you cut power to all outlets at once, helping avoid battery depletion during extended parking or when devices aren’t in use.

• Clear voltage readout for quick battery-check reference
• Warning LED for abnormal voltage conditions
• Master on/off switch to prevent parasitic drain
• Voltage readouts intended for reference; professional testing recommended for diagnostics

Who is this for: The HURMAI 12V Socket Power Outlet suits drivers who need reliable, multi-device power in cars, trucks, boats, or RVs—especially tradespeople, road travelers, and anyone running dash cams, portable refrigerators, air compressors, or power inverters. It’s built for users who require extended cable reach and the ability to run several medium-to-high-draw devices simultaneously while keeping a handy USB fast-charge option available.
