The LDNIO SC3412 Power Extension with 20W USB-C PD is a versatile power strip designed for homes, offices, workstations, entertainment setups and everyday charging needs. It combines three AC power outlets with one USB-C PD port and three USB-A QC 3.0 ports, allowing you to power household electronics while charging multiple mobile devices from the same extension board. LDNIO rates the AC section at up to 2500W, while the USB charging system provides up to 38W total charging power.

The SC3412 is particularly useful for users who want a conventional power extension with built-in fast charging. Its USB-C PD port supports up to 20W, making it suitable for compatible iPhones, Android smartphones, tablets and other USB-C devices, while the three USB-A ports support QC 3.0 up to 18W.

With a 2-meter heavy-duty power cable, universal AC outlets and a safety-focused construction using fire-resistant PC material, the SC3412 is designed to provide convenient power expansion without requiring separate USB wall chargers.

3 Universal AC Power Outlets

The SC3412 provides three AC outlets, giving you additional connections for compatible electrical appliances and electronics.

The universal outlet design supports various plug standards, with LDNIO listing US, EU and UK plug options for the product.

You can use the AC outlets for devices such as:

• Laptop chargers
• Desktop computers
• Monitors
• Speakers
• Routers
• Gaming consoles
• Lamps
• TVs and accessories
• Other compatible household electronics

The total AC load should remain within the extension's 10A / 2500W maximum rating.

2500W Maximum Power Capacity

The SC3412 is rated for up to 2500W of AC power at 10A, with an input range of 100–250V and 50–60Hz.

This gives the extension enough capacity for many everyday household and office appliances.

However, 2500W is the maximum rated load, not a recommendation to continuously operate the extension at its limit. The combined consumption of connected appliances should always remain within the rated capacity.

20W USB-C PD Fast Charging

One of the main advantages of the SC3412 is its integrated USB-C Power Delivery port.

The USB-C port supports up to 20W PD 3.0 output, with the following listed profiles:

• 5V / 3A
• 9V / 2.22A
• 12V / 1.67A
• 20W maximum

This makes the USB-C port suitable for fast charging compatible smartphones, tablets and other USB-C devices.

For compatible iPhones, 20W USB-C PD can provide significantly faster charging than a basic 5W USB charger.

Three USB-A QC 3.0 Ports

Alongside USB-C, the SC3412 provides three USB-A ports with QC 3.0 fast charging support.

The listed QC 3.0 output is:

• 5V / 3A
• 9V / 2A
• 12V / 1.5A
• Up to 18W

These ports are useful for devices that still use USB-A charging cables, including smartphones, earbuds, smartwatches, power banks and Bluetooth accessories.

Up to 38W USB Charging

The SC3412 combines its USB-C PD and USB-A QC charging system for up to 38W total USB output under the specified configuration:

20W USB-C PD + 18W USB-A QC 3.0 = 38W

This gives you more flexibility than a standard power strip with basic USB charging.

You can use the USB-C port for a modern fast-charging smartphone while using the USB-A ports for additional accessories.

Charge Multiple Devices at the Same Time

The SC3412 combines:

3 AC outlets + 4 USB charging ports

This gives you multiple charging and power connections from one extension.

For example:

Connection	Example Device
AC Outlet 1	Laptop charger
AC Outlet 2	Monitor
AC Outlet 3	Speaker
USB-C PD	Smartphone
USB-A QC 1	Earbuds
USB-A QC 2	Power bank
USB-A QC 3	Smartwatch

The actual charging output depends on the connected devices and charging configuration.

2-Meter Heavy-Duty Cable

The SC3412 comes with a 2-meter heavy-duty power cord, giving you greater flexibility when the wall outlet is located away from your desk or equipment. LDNIO specifically highlights the cable as being designed to provide optimal power flow to connected devices.

The extra cable length can be particularly useful for:

• Office desks
• Gaming setups
• TV cabinets
• Workbenches
• Bedrooms
• Study tables

Universal Power Socket Design

The SC3412's universal AC outlets are designed to accommodate compatible plugs from multiple standards.

This makes it easier to connect different chargers and appliances without requiring multiple plug adapters.

The design also accommodates larger power adapters, which can be difficult to fit into tightly spaced conventional extension boards.

PD 3.0 Fast Charging

USB-C PD 3.0 provides a standardized fast-charging method for compatible USB-C devices.

With up to 20W available, the SC3412 is well suited to everyday charging of:

• iPhones
• Android smartphones
• Tablets
• Power banks
• USB-C accessories
• Compatible portable devices

The connected device determines how much power it actually draws.

QC 3.0 Fast Charging

The three USB-A outputs support Qualcomm Quick Charge 3.0, with up to 18W output per supported charging configuration.

This is useful for compatible Android smartphones and other QC-compatible products.

Non-QC devices can still use the USB ports, but charging speed depends on their supported charging technology.

Safety-Focused Construction

LDNIO describes the SC3412 as using high-grade fire-resistant PC material and a 9-protection design.

The safety-oriented construction is intended to provide additional protection for the power strip and connected electronics during everyday use.

The extension should nevertheless be used within its rated load and with undamaged plugs, cables and appliances.
