Introduction

Nintendo has released its next-generation gaming console, the Switch 2, featuring significant upgrades in hardware performance, display quality, and controller design. In this article, we’ll take a closer look at the teardown of the official charging dock — one of the core accessories for the Switch 2.

Beyond serving as a charging station and a resting place for the console when not in use, the dock also supports 4K resolution output in TV mode and comes equipped with a gigabit Ethernet port for faster and more stable online gameplay. Let’s take it apart to see its internal components and structure.

Product Appearance

The packaging continues the classic red theme, with the front featuring images of the product itself as well as elements from Mario Kart and other related graphics.

The packing list and precautions are printed on the side.

The other side is printed with product usage scenarios.

The Nintendo Switch 2 is secured with cardboard.

The package includes the Switch 2 console, Joy-Con set, dock, charger kit, HDMI cable, and more.

The official charging dock continues the minimalist design style, featuring a contrast of matte and glossy finishes on the surface and inside the slot.

The front-facing logo is noticeably larger, and the curves at both ends of the top are more pronounced — subtle details that set it apart from the previous model.

At the center of the slot is a USB-C male connector, with a protective plate held up by an internal spring mechanism.

One side of the dock is also equipped with two USB-A ports.

The edges at the back are smoothly rounded, with the Nintendo logo positioned at the center.

When you open the back cover, the spec information is located on the upper left side.

Located here are the USB-C, HDMI, and Ethernet ports.

This area displays the labels for AC Adapter, HDMI Out, and LAN ports.

Input: 20V 3A

Output: 15V 2.8A

It is certified by NOM, NYCE, CE, UKCA, KC, and others.

There are anti-slip pads on both sides of the bottom, along with numerous ventilation holes.

The length is about 200.05 mm (7.88 inches).

The height is about 112.29 mm (4.42 inches).

The thickness is about 48.78 mm (1.92 inches).

The weight is about 380 g (13.4 oz).

Here’s how the Nintendo Switch 2 looks when placed in the dock.

Using the official 60W charger with the dock to charge the Switch 2, the charging power is about 17.04W.

Teardown

Next, let's take it apart to see its internal components and structure.

Screws are found under the bottom anti-slip pad.

Remove the screws to open the bottom cover. The central USB-C port is a separate module, secured with screws.

The side LED indicator is soldered to a ribbon cable, which is secured with a screw.

Open the back cover, the casing is made of fire-resistant PC+ABS material.

The casing houses the PCBA module and a fan. The PCB is covered with a metal shielding plate and secured with screws.

The PCBA module and fan are connected via a ribbon cable with a plug-and-play design.

The other end of the indicator light’s ribbon cable is also a plug-and-play connector.

The bottom USB-C is also connected to the PCB via a ribbon cable.

Removing the metal shielding plate reveals that the PCB is also secured by mounting posts, with a reinforcement pad attached to the ribbon cable on the left side.

Remove the PCB and fan.

Remove the USB-C output port.

The back of the PCBA module is equipped with a metal heat sink.

USB-C, HDMI, RJ45, and USB-A connectors are soldered on both sides of the PCB, with a shielding cover over the hub circuitry area.

Opening the shield reveals components such as the hub controller, video converter chip, and Ethernet controller.

Thermal pads are attached to the synchronous buck converter and buck inductor used for step-down output to the USB-A ports.

On the back, there are components including an MCU, two USB-C port controllers, and a memory chip.

For power control of the USB-C input port, there are two back-to-back MOSFETs marked with "SNA".

The USB-C input port controller is from Infineon, marked with CP10356AT, and uses a QFN40 package.

The USB hub controller is the GL3510 from Genesys, a four-port, low-power hub controller that supports USB 3.0 and is backward compatible with USB 2.0. It features a built-in switching regulator for power supply. In this design, the GL3510 is used for USB 3.0 expansion, connecting three USB-A ports and cascading to another GL3510.

Summary of ChargerLAB

Here is the component list of the Nintendo Switch 2 Official Charging Dock for your convenience.

The charging dock retains the classic design, but with more rounded corners. Compared to the previous version, it still features the two key ports: HDMI and gigabit Ethernet. Thanks to the improved performance of the Switch 2, the gaming experience in TV mode is significantly enhanced with higher image quality.

After taking it apart, we found that it uses noticeably upgraded components and, for the first time, includes an active cooling fan to ensure stable long-term operation. The PCB is covered with shielding and heat dissipation metal plates, and the hub circuitry is enclosed under the dedicated shielding cover. Multiple buck circuits are also included in the design. Key components are sourced from internationally recognized manufacturers such as STMicro, TI, Infineon, and REALTEK — all known for their high-performance, reliable chips — ensuring the overall build quality of the dock meets a high standard.
