Introduction

Inno3C has solidified its reputation as a leading Hong Kong tech brand through deep-rooted collaborations with top-tier carriers like csl, SmarTone, 3HK, and CMHK.

By embedding its product lineup into carrier marketing strategies—from exclusive pre-order gifts to popular member reward programs—Inno3C has become a go-to brand for enhancing mobile plan value.

We’ve previously broken down their smart magnetic wireless charger, which combines a digital display with 20W bidirectional PD charging. Now, we are turning our attention to their newest release: a feature-packed 7-in-1 USB-C multi-function docking station.

Inno3C has combined high-performance connectivity with a striking industrial look. The dock supports 100W PD input, 4K@30Hz video output, and a versatile array of ports—USB 3.0, dual USB 2.0, and integrated SD/TF card readers. Housed in a premium aluminum shell with a see-through transparent base, it perfectly captures a modern "geek" aesthetic.

Now, let’s peel back the layers to see how Inno3C has engineered this device from the inside out.

Product Appearance

Teardown of Inno3C 7-in-1 Docking Station-Chargerlab

The packaging features the Inno3C logo and a product render on the front, with 4K and 100W PD charging icons clearly displayed in the upper right corner.

The rear of the packaging details the product specs, includes an interface diagram, and lists all functional feature icons.

Product Specs:

Model: i-CSU7

Type-C Output: 100W PD (Max.)

USB 3.0: 5Gbps

USB 2.0: 480Mbps

TF/SD: 480Mbps

HDMI: 4K 30Hz

The side of the packaging lists all the supported interfaces vertically, covering the USB-C, HDMI, USB 3.0, dual USB 2.0, and TF/SD card ports.

The other side of the packaging displays the product name and brand logo.

Unpacking the contents reveals the Inno3C 7-in-1 docking station along with its retail packaging.

Featuring an integrated cable design, the dock’s top shell is crafted from space-gray aluminum alloy, accented with a grooved texture that enhances visual depth while promoting heat dissipation. The integrated cable is wrapped in a durable black braided material.

The cable joint is reinforced with thick injection molding, improving overall durability and bend resistance.

The cable features a high-density nylon braided sleeve, providing excellent durability, tangle resistance, and a longer overall service life.

The USB-C plug includes extended injection-molded strain relief at the cable connection point for enhanced durability.

The length of the integrated cable is approximately 15cm.

The edges of the dock’s metal top cover are chamfered for a clean, premium look.

The underside of the dock features a transparent gray PC, allowing for a striking look into the internal PCBA and components—perfect for tech enthusiasts. To keep the device securely in place, the base is equipped with four circular anti-slip rubber feet at the corners.

Here is the aluminum alloy top cover, its grooved surface delivers a bold, sharp, and distinctly rugged look.

The transparent base allows for a clear view of the internal layout, including the SMDs and conversion chips.

The raised anti-slip pads ensure stability on surfaces and help prevent scratches to the transparent base.

The side of the unit features a USB-C port (100W PD input), an SD card slot, and a TF card slot.

The right side of the dock features a seamless, high-quality fit where the metal top cover meets the transparent base.

The other side of it houses two USB 2.0 ports, one USB 3.0 port and one HDMI video port.

The built-in cable exits from the center of the dock housing.

The length of the dock is about 115.23mm (4.537 inches).

The width of the dock is about 46.97mm (1.849 inches).

The thickness of the dock is about 17.41mm (0.685 inches).

The weight is about 117.3g (2.91 oz).

That's how big it is in the hand.

Teardown

Remove the four anti-slip pads and the four screws beneath them to separate the metal top cover from the transparent base and extract the internal PCBA module.

The topside of the PCBA features the SMDs and all primary interface ports, including USB-A, USB-C, HDMI, and TF card slots.

Here is the back of the PCBA. It is clean and well-organized, housing the main conversion chip, the crystal oscillator, and the SD card slot.

Here are two USB 2.0 ports, both featuring black plastic sheets.

The USB 3.0 port utilizes a sink-mount through-hole soldering process and a blue plastic sheet for easy identification, with clearly visible internal contact pins.

The HDMI video port is secured to the board using the sink-mount through-hole soldering process for enhanced structural integrity.

The USB-C PD input port also features the sink-mount through-hole soldering process, which helps keep the docking station’s design compact and thin.

The SD card slot and TF card slot are located on opposite sides of the PCBA.

The TF card slot includes a built-in spring-loaded mechanism for easy card removal.

The connection between the integrated cable and the PCBA features neat, high-quality solder joints for each wire, reinforced with injection molding to provide additional durability.

The rear view of the cable connection clearly shows the colored wire leads and the injection molding protection, which is designed to increase pull resistance and overall durability.

The dock utilizes the video conversion chip is from ASL, model CS5266, housed in a QFN68 package, this high-performance chip facilitates USB Type-C to HDMI 2.0b (4K@30Hz) conversion. It natively supports up to 100W PD pass-through and works in tandem with a USB hub chip to enable USB 3.1 high-speed data transmission.

A VBUS MOSDFET is from AOS, model AO4805, dual PMOS, -30V and 15mΩ, housed in a SOIC-8 package.

Here is the info about AO4805.

The card reader chip is from Genesys, model GL823K, housed in a SSOP16 package. It's a highly integrated controller chip designed for USB 2.0 SD/MSPRO card reader functionality.

The USB hub chip is from Prolific, model MA8601, housed in a SSOP28 package. It's a 4-port USB 2.0 controller that enables signal expansion for multiple external USB devices.

A 12.000 MHz crystal oscillator is positioned next to the USB hub chip to provide the required system clock signal.

There are two components, marked 702.

There is a chip, marked HU1Q.

Another one is marked with CE9Nh.

This is a surface-mount alloy choke.

Well, those are all components of the Inno3C 7-in-1 docking station.

Summary of ChargerLAB

The Inno3C 7-in-1 USB-C docking station combines form and function. Its dark gray aluminum exterior features a fluted design that optimizes thermal management and provides a high-quality feel, complemented by a transparent base that gives it a distinct tech-enthusiast aesthetic.

On the configuration front, it covers all the essentials—HDMI output, 100W PD power delivery, USB-A expansion, and SD/TF card slots—making it a perfect companion for everyday office tasks.

Internally, the PCBA design is clean and professional. To ensure robust performance over time, the interface ports are primarily secured using sink-mount through-hole soldering, enhancing their resilience to wear and tear.

The device is powered by a high-efficiency chip set, including the ASL CS5266 for A/V conversion, the Genesys GL823K for reliable card reading, and the Prolific MA8601 to handle USB hub data management. Together, they form a cohesive, high-performance expansion system.
