Prime Day pushes Thunderbolt docks into the spotlight, letting MacBook users expand ports without buying a desktop. Eight deals hit Amazon, offering options from 17‑port Ugreen Maxidok to compact Anker Prime. Each unit plugs into a single Thunderbolt port, unlocking USB‑A, USB‑C, Ethernet, and SD slots that most laptops lack.

Ugreen’s 17‑port model costs $349.99 for Prime members, down from $499. It delivers 120Gbps Thunderbolt 5 throughput, dual 8K or dual 6K displays, and a PCIe Gen4x4 NVMe slot that can host up to 8TB. Anker’s 14‑port dock, priced at $319.99, offers HDMI 2.1, DisplayPort 2.1, and a 3.5mm audio jack.

Plugable and Cal Digit bring 16‑ and 15‑port bundles for $339.95 and $319.96 respectively, both featuring dual HDMI 2.1 and 2.5Gbps Ethernet. Wavlink’s Thunderbolt 4 dock, the cheapest at $151.97, still supplies 4‑K 60Hz output and 140W charging, proving a budget alternative for users who don’t need Thunderbolt 5 speed.

These discounts, ranging up to $155 off original prices, give power users a chance to scale their Mac setups without a new machine. By concentrating on connectivity, the deals sidestep the trend of expensive all‑in‑one workstations, showing that modular expansion remains a viable, cost‑effective path for modern workflows.
