USB question
Keep the connector form separate from cable-specific charging/current evidence and the exact devices participating in power negotiation.
The answer
Short answer No. Charging depends on the exact cable, charger and device, not on the USB-C ends.
No. USB-C ends alone do not establish one charging capability. The exact cable, source and load requirements must be resolved separately.
Why the simple answer is not enough
Use the cable profile to see whether charging/current capability is documented, conditional or unknown.
Check the charger/source and device/load independently; a cable does not define the entire power path.
Do not turn a connector match into a replacement-power or safety approval.
Your next step
They reorganize facts and uncertainty already represented in the atlas. Exact-device, cable, protocol, power, safety and performance requirements remain separate where the evidence says they are separate.

The TS4 manual separates three ordinary 10 Gb/s USB-C data ports: the front-left port is specified for up to 20 W, while the other two are specified for up to 7.5 W each.
Claim scope: CalDigit TS4 only; front-left is the manual’s wording and orientation. Interface ratings do not establish actual charging or transfer speed.
Source links: S449 · Evidence trail → (private workspace)
CalDigit distinguishes the TS4 Thunderbolt host connection from two downstream Thunderbolt connections; the support page rates host charging up to 98 W and each downstream Thunderbolt port up to 15 W.

CalDigit describes the ordinary TS4 USB-C ports as data-only while separately specifying their power outputs; its monitor guidance uses the DisplayPort or suitable downstream Thunderbolt connections instead.

Intel’s Thunderbolt 5 brief describes balanced 80 Gbit/s in each direction and reconfiguration for high display traffic to 120 Gbit/s transmit with 40 Gbit/s receive. These link modes are not symmetric 120 Gbit/s or a file-transfer benchmark.

Apple’s Thunderbolt 5 cable overview groups Thunderbolt 3, Thunderbolt 4 and USB4 under an up-to-80-Gb/s phrase, while Intel’s comparison gives Thunderbolt 4 a 40-Gbit/s link. This grouped wording is not evidence that an older Thunderbolt host gains an 80-Gbit/s mode.
Claim scope: Unresolved scope of grouped manufacturer wording; do not distribute the largest number across every listed protocol or infer an undocumented revision explanation.

Apple advertises up to 120 Gb/s for its Thunderbolt 5 cable. Intel explains the technology’s high-display-bandwidth mode as 120 Gbit/s in one direction with 40 Gbit/s in the other, rather than a symmetric or measured storage-transfer rate.
Claim scope: Manufacturer cable advertisement interpreted with the technology brief; no actual negotiated link or workload was measured.
