Independent testing
How much independent testing exists for each docking station
Of the 7 docking stations we track, 4 have been physically measured by at least one independent lab. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.
| Product | Independent labs | Metrics measured | Outlets on record |
|---|---|---|---|
| Razer Thunderbolt 4 Dock Chroma | 1 | 6 | 1 |
| CalDigit TS4 | 1 | 2 | 2 |
| Anker 777 Thunderbolt Docking Station (Apex) | 1 | 1 | 1 |
| Belkin Connect Pro Thunderbolt 4 Dock (INC006) | 1 | 1 | 2 |
| CalDigit TS3 Plus | 0 | 0 | 2 |
| Kensington SD5700T | 0 | 0 | 1 |
| OWC Thunderbolt 4 Dock | 0 | 0 | 1 |
Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the Docking Stations buying guide and the reviewers we cite.
