The LDNIO SEW4485 Tower Extension is a multifunctional desktop power station designed to combine everyday AC power distribution, wired fast charging, wireless charging and timed power control in one compact tower-style unit. It features 4 EU AC power sockets, a 30W USB-C PD port, a 30W USB-A QC 3.0 port, 2 USB-A AUTO-ID ports, and a 15W wireless charging pad. LDNIO also equips the unit with a 24-hour timer switch, fire-resistant PC construction and a 200cm power cable.

With a rated capacity of 2500W / 10A / 250V, the SEW4485 is designed for powering multiple compatible electronics while also keeping phones and other USB devices charged. Its vertical tower design takes up less desk space than many conventional extension boards and provides a more organized charging area.

4 EU Power Sockets

The SEW4485 provides four EU AC outlets, allowing several mains-powered devices to share one power source. LDNIO specifically lists four EU outlets as one of the unit's main features.

You can use the sockets for compatible devices such as:

• Laptops
• Desktop computers
• Monitors
• Printers
• TVs
• Gaming consoles
• Speakers
• Desk lamps
• Routers
• Other household electronics

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

2500W High-Power Capacity

The SEW4485 is rated at up to 2500W, 10A and 250V, providing substantial capacity for everyday home and office electronics.

This makes it more than a simple phone-charging station. It can serve as a centralized power point for a desktop workstation, entertainment center or other multi-device environment.

Important: 2500W is the maximum rated capacity for the AC power section. It does not mean that every connected device can independently consume 2500W. Always keep the combined load within the extension's rating.

30W USB-C PD Fast Charging

The built-in USB-C PD port can deliver up to 30W.

LDNIO specifies the USB-C output as:

• 5V / 3A
• 9V / 3A
• 12V / 2.5A
• 30W maximum
• PPS: 3.3V–11V / 3A

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

Because the port supports USB Power Delivery and PPS, it is better suited to modern USB-C devices than a basic 5V charging port.

USB-A QC 3.0 Fast Charging

The SEW4485 also includes a USB-A QC 3.0 port.

The manufacturer specifies up to 30W maximum for the QC-capable USB-A output, with supported profiles including:

• 5V / 3A
• 9V / 3A
• 12V / 2.5A

This provides convenient fast charging for compatible USB-A devices.

2 USB-A AUTO-ID Ports

Alongside the USB-C PD and QC port, the tower provides two additional USB-A AUTO-ID ports.

Each AUTO-ID output is specified at up to 5V / 2.4A, 12W.

These ports are useful when charging devices that do not require higher-power USB-C PD charging.

You can use them for:

• Smartphones
• Earbuds
• Smartwatches
• Bluetooth speakers
• Power banks
• Tablets
• USB accessories

15W Wireless Charging

One of the standout features of the SEW4485 is its integrated 15W wireless charging pad.

LDNIO specifies wireless output at:

5W / 7.5W / 10W / 15W maximum

depending on the connected device and supported wireless-charging standard.

This means compatible Qi-enabled smartphones can be placed directly on the charging surface without connecting a cable.

It is particularly convenient on a desk or bedside table where the phone can remain accessible while charging.

Charge Multiple Devices at Once

The SEW4485 is designed for environments where several devices need power simultaneously.

For example, a desktop setup could use:

• AC socket → monitor
• AC socket → laptop charger
• AC socket → speaker
• AC socket → desk lamp
• USB-C PD → smartphone
• USB-A QC → power bank
• AUTO-ID → earbuds
• Wireless pad → another smartphone

The actual available USB output depends on the combination of ports being used. LDNIO specifies 32W maximum total USB/wireless output for the relevant output configurations.

24-Hour Timer Switch

The SEW4485 includes a 24-hour timer switch, allowing users to control when connected power is active. LDNIO lists the 24-hour time switch as one of the product's key features.

This can be useful for devices that do not need to remain powered continuously.

A timer can help:

• Reduce unnecessary power usage
• Schedule connected equipment
• Turn devices off after a selected period
• Improve convenience during daily routines

T-Shaped Cable Management

The SEW4485 uses a T-shaped cable-management design intended to help keep a desktop organized.

Instead of having a conventional extension board spread horizontally across a desk, the tower arrangement provides a centralized location for power and charging connections.

This can be especially useful for:

• Gaming desks
• Home offices
• Study tables
• TV cabinets
• Workstations

Space-Saving Tower Design

The vertical tower construction allows the SEW4485 to provide several power and charging options without requiring a large horizontal footprint.

Its upright form makes it easy to place beside a monitor, laptop, desktop PC or other workstation equipment.

200cm Power Cable

LDNIO specifies a 200cm power cable for the SEW4485.

The 2-meter cable provides flexibility when the wall outlet is not directly beside your desk.

It can be useful for:

• Office desks
• Gaming stations
• Bedside tables
• TV units
• Workstations
• Study areas

Fire-Resistant PC Material

The SEW4485 uses fire-resistant PC material, according to LDNIO. The manufacturer also describes a 9-layer multi-protection design.

This construction is intended to provide additional protection and durability during everyday use.

As with any power extension, protection features do not replace safe electrical practices. Do not exceed the rated load or use damaged plugs, cables or sockets.

9-Layer Multi-Protection

LDNIO markets the SEW4485 with a multi-protection system designed to provide additional safety during operation.

The exact protection behavior depends on the internal circuit design, but users should still operate the extension within its specified voltage, current and power limits.
