Finding a certified Thunderbolt 4 dock under $150 used to be a pipe dream. We tracked down the three best options — including an absurdly cheap Amazon Basics dock, a premium refurbished Microsoft Surface dock, and a sale-priced Plugable workhorse — so you can expand your Windows laptop without breaking the bank.
Certified Thunderbolt 4 dock at an absurd $34.99 — 61% off list price. 85W PD, dual 4K@60Hz, and all the essential ports for a fraction of what competitors charge.
Aluminum build, 96W PD, and rock-solid reliability for ~$89.99 open-box — a $229 dock for half the price. Ideal for Surface and high-power Windows laptops.
11 ports including 2.5Gb Ethernet and SD card reader. Normally $199 but dips to ~$150. The most future-proof TB4 dock when you can catch a deal.
A Thunderbolt 4 dock is the single best upgrade you can give a modern Windows laptop. One cable delivers power, high-speed data, external displays, and networking — turning a thin-and-light ultrabook into a true desktop workstation.
The catch? Most certified TB4 docks hover between $200 and $350. But there are ways to get the full Thunderbolt 4 experience for under $150 — you just have to know where to look. We dug through the current market to find the things actually worth buying for budget-conscious Windows users.
Before we dive into picks, here's what matters most when you're shopping on a budget:
Price: $34.99 (was $89.99)1
Yes, you read that right. Amazon Basics makes a certified Thunderbolt 4 dock, and it's currently selling for $34.99 — a 61% discount that makes it the cheapest TB4 dock we've ever seen.1
For that price you get:
The build is plastic and the cable is short, but at this price those are easy compromises. Tom's Hardware flagged this deal as a no-brainer for anyone who needs Thunderbolt 4 connectivity on a tight budget.1
The catch: Availability is unpredictable. Amazon Basics stock fluctuates wildly, and at $34.99 it sells out fast.
Price: ~$89.99 (refurbished/open-box)2
Microsoft's Surface Thunderbolt 4 Dock is one of the best-built docks on the market — machined aluminum, a clean front-facing USB-C port, and rock-solid stability. The retail price is $229, but refurbished and open-box units regularly land at Best Buy for $89.99.2
What you get:
The only downside: the downstream USB-C ports are Thunderbolt 4, but they're USB-C form factor only — no full-size USB-A on the back. You'll want a USB-A hub for legacy peripherals.
Price: ~$150 (during sales, normally $199)
Plugable's TBT4-UD5 is consistently rated as one of the best Thunderbolt 4 docks on the market by PCWorld and other reviewers.3 It normally retails for $199, but we've seen it dip to around $150 during Amazon and B&H sales.
Why it's worth stretching for:
The TBT4-UD5 is the pick if you need maximum port variety and don't mind waiting for a sale. It's the most future-proof option here, and it's backed by Plugable's excellent support team.3
| Spec | Amazon Basics TB4 | Microsoft Surface TB4 (Refurb) | Plugable TBT4-UD5 (Sale) |
|---|---|---|---|
| Power Delivery | 85W | 96W | 96W |
| Display Support | Dual 4K@60Hz | Dual 4K@60Hz | Dual 4K@60Hz / 8K |
| USB-A Ports | 3x (5Gbps) | 1x (10Gbps) | 4x (10Gbps) |
| Ethernet | 1Gb | 1Gb | 2.5Gb |
For under $150, you have two paths:
Path A: Buy a new, cheap USB4 or Amazon Basics TB4 dock. The Amazon Basics dock is certified Thunderbolt 4 at an absurd price. It's the safest bet if you just need the basics and want a warranty.
Path B: Buy a refurbished/open-box premium dock. The Microsoft Surface TB4 dock at $89.99 gives you better build quality and higher power delivery for about the same money as a mid-range USB4 dock. Just make sure the refurbisher offers a return policy — Best Buy's open-box program is solid.2
Our take: If you can find the Amazon Basics dock in stock, buy it immediately. If not, the refurbished Microsoft dock is the better long-term value. And if you need the most ports possible, save up for the Plugable on sale.
