Introduction
CalDigit is a well-established American brand known for its high-quality accessories, including docking stations, storage devices, and cables. Their products typically feature aluminum alloy enclosures, which provide excellent heat dissipation, strong structural integrity, and a premium look and feel. With comprehensive functionality and a wide range of ports, CalDigit has become synonymous with high-end docking solutions.
We recently got our hands on CalDigit’s TS5 Plus Thunderbolt 5 Dock. This dock features an aluminum alloy chassis and is powered by a 330W external power supply. On the front panel, it offers USB-C and USB-A ports, TF and SD card readers, and a 3.5mm audio jack. The rear panel includes Thunderbolt 5 ports, a DisplayPort 2.1, a 10Gb Ethernet port, additional USB-C and USB-A ports, and an audio interface.
The Thunderbolt 5 upstream port supports 140W PD 3.1 fast charging, while the Thunderbolt 5 downstream port and front USB-C port each deliver 36W fast charging, allowing multiple devices to be charged simultaneously.

Summary of ChargerLAB
Here is the component list of the CalDigit TS5 Plus Thunderbolt 5 Dock for your convenience.
It features an aluminum alloy casing. The front panel includes USB-C and USB-A ports, as well as TF and SD card slots. The rear panel has a Thunderbolt 5 port, a 10 GbE network port, and a DP 2.1 port. The Thunderbolt 5 upstream port supports 140 W fast charging, while the Thunderbolt 5 downstream port and the front-panel USB-C port both support 36 W fast charging.
After taking it apart, we found that it contains two PCBA modules: one for Thunderbolt 5 expansion and another for other interface expansion. Heat-generating chips are thermally connected to an aluminum alloy shield via thermal pads, dissipating heat through the casing. An Intel JHL9480 Thunderbolt 5 controller manages the interface expansion, ASMedia controllers handle the USB interface expansion, and a MARVELL AQC113 chip supports the 10 GbE network port expansion.
The USB-C fast-charging port uses a Texas Instruments BQ25758 for synchronous buck-boost control, paired with a Leadpower LM80080NAK8A for voltage conversion, and filtered with TRUSTCAP capacitors to ensure efficient, stable, and reliable output, meeting the power demands of high-wattage devices.
