CalDigit TS5 Plus Review
The most port-dense and highest-power Thunderbolt 5 dock available, with dual 4K/240Hz and 10GbE headroom that no rival in this shortlist matches — at a premium price and with a small number of independent heat reports worth knowing about.
At a Glance
This model is best suited to power users and creative professionals who need the widest port set and fastest wired networking available in a single dock, and have a genuine Thunderbolt 5 laptop to unlock it. Its strongest buying points are 20 total ports including dual card readers, 10GbE and DisplayPort 2.1, 140W host charging, the highest in this shortlist, and dual independent USB controllers boost aggregate USB throughput for multi-drive workflows.
Technical Assessment
The TS5 Plus pairs its 20-port count with 10GbE networking, the fastest wired networking on any dock in this shortlist, and a compact footprint under 1kg despite its dense port layout.
Performance
Independent testers consistently point to the 20-port layout, dual USB controllers and 10GbE as the standout capabilities in this class, with reviewers describing the dock as having ‘instantly integrated’ into demanding workflows. Display support is strong but host-dependent, topping out at dual 4K@240Hz or triple 4K@144Hz only on the newest Thunderbolt 5 Windows PCs and top-tier Apple Silicon chips.
Reliability and Ownership
CalDigit’s own store shows a small but perfect 5.0/5 rating from 6 reviews. Independent coverage is more mixed: AppleInsider logged multiple third-party reports of the unit running hot, including one claim of 55°C surface temperature, though the outlet had not reproduced this itself and was following up with CalDigit. This is disclosed as a genuine open question rather than a confirmed defect.
