How We Picked
We dug through the latest 2026 reviews from The Verge, Wirecutter, MacRumors, CNET, and Tom’s Guide, cross-referenced them with real owner feedback on Reddit’s r/macbookpro and r/UsbCHardware, and checked current Amazon pricing. Every pick here has been verified to work without issues on the M4 MacBook Pro lineup. We eliminated any hub with known thermal throttling, DisplayLink driver instability, or sub-4.0 Amazon ratings.

Best Overall: CalDigit TS4
Best Overall CalDigit TS4
After five years on the market, the CalDigit TS4 ($379.99 on Amazon, originally released 2022) has received a firmware update for M4 Macs and remains the undisputed king of Thunderbolt 4 docks. It’s not cheap, and it’s not small, but if you need a single cable to power your entire desk setup — dual monitors, wired Ethernet, fast external storage, and a full keyboard/mouse suite — this is the one.
The TS4 packs 18 ports into a chunky aluminum chassis. That includes three downstream Thunderbolt 4 ports (40Gbps each), five USB-A ports (two at 10Gbps, three at 5Gbps), two USB-C 10Gbps ports, 2.5GbE Ethernet, UHS-II SD and microSD slots, DisplayPort 1.4, and separate 3.5mm audio in/out. Power delivery hits 98W — enough to charge a 16-inch M4 Max MacBook Pro at full speed under load.
Stability is the TS4’s superpower. While other docks occasionally drop connections or glitch out after macOS updates, the TS4 just works. The Verge called it “unbeatable” in their 2025 re-review, and MacRumors forums show zero compatibility complaints with M4 chips. The 2.5GbE Ethernet is a future-proofing bonus for anyone with a fast NAS or fiber internet.
If you’re building a permanent desk setup, the TS4 is the last dock you’ll buy. For a deeper look at Thunderbolt 4 versus USB-C trade-offs, check our Thunderbolt 4 vs USB-C Hub Guide.
What We Like
- 18 ports — more than any competitor, including dual Thunderbolt 4 downstream
- 98W power delivery charges M4 Max at full speed
- 2.5GbE Ethernet for fast wired networking
- UHS-II SD and microSD card readers for photographers
- Rock-solid stability — no disconnects or driver issues
- Aluminum build feels premium and acts as a heatsink
What We Don\’t
- $379.99 is expensive — overkill for single-monitor users
- No HDMI 2.1 (uses DisplayPort 1.4 for high-refresh displays)
- Large footprint (11.5 x 3.5 x 1.2 inches) — takes up significant desk space
- Only one Thunderbolt 4 upstream cable included

Best Budget Under $100: Anker PowerExpand 5-in-1 (2026 Model)
Best Budget Under $100 Anker PowerExpand 5-in-1
The 2026 Anker PowerExpand 5-in-1 ($49.99 on Amazon, released January 2026) is a targeted solution for a specific problem: you have a 120Hz ProMotion external monitor and you don’t want to spend $150+ to drive it. This is the cheapest way to get HDMI 2.1 (4K@120Hz) out of your M4 MacBook Pro, and it does it without overheating — a problem that plagued Anker’s previous model.
This is a USB-C 3.2 Gen 2 hub (10Gbps), not Thunderbolt 4. That means you’re limited to a single external display and slower data transfer than a Thunderbolt dock. But the port selection is smartly curated: one HDMI 2.1 port, one USB-C PD passthrough (100W), one USB-A 10Gbps, one SD 3.0 card slot (UHS-I), and one 3.5mm audio jack. It’s about the size of a pack of gum and weighs nothing.
Tom’s Guide called the HDMI 2.1 support “a game-changer at this price,” and CNET noted that Anker fixed the thermal issues of the previous generation. The 100W passthrough is generous — it’ll charge a 14-inch M4 Pro at full speed while the hub is in use.
The catch: no Ethernet, no microSD slot (only full-size SD), and the SD reader is UHS-I (104 MB/s max) — fine for casual photo transfers, frustrating for pro video workflows. If you need fast card reads or wired internet, look elsewhere.
What We Like
- HDMI 2.1 with 4K@120Hz support — works with ProMotion monitors
- Only $49.99 — cheapest hub that does 120Hz
- Compact and portable (fits in a pocket)
- 100W passthrough charging is generous for the price
- No thermal throttling in the 2026 model
What We Don\’t
- No Ethernet port
- No microSD slot (only full-size SD)
- SD card reader is UHS-I (slow for pro video)
- Limited to one external display
- USB-A port is only 10Gbps, not Thunderbolt speed

Best for Dual External Displays: Plugable UD-ULTC4K
Best for Dual External Displays: Plugable UD-ULTC4K
The Plugable UD-ULTC4K ($179.99 on Amazon, released late 2025) is the answer to the most common MacBook Pro complaint: “I need two external monitors, and I don’t want to mess with DisplayLink drivers.” This Thunderbolt 4 dock drives dual 4K@60Hz displays natively — no software, no compromises, no glitches.
Plugable updated this dock specifically for M4 Macs, fixing the intermittent display dropouts that plagued the M3-era version. The port selection is practical: two HDMI 2.0 ports (4K@60Hz each), one Thunderbolt 4 downstream, two USB-A 10Gbps, one USB-C 10Gbps, 2.5GbE Ethernet, and UHS-II SD/microSD combo slots. Power delivery is 96W — enough for any M4 MacBook Pro.
Wirecutter named it the best dock for dual-monitor M4 setups in their 2026 update, and MacRumors users confirm it “just works” without the driver headaches of DisplayLink-based docks. The UHS-II card reader is genuinely fast (300 MB/s+ with the right cards) — a real plus for photographers and videographers.
The trade-off: HDMI 2.0 means no 120Hz support. If you have a 120Hz ProMotion monitor, you’ll be stuck at 60Hz. There’s also no DisplayPort output, and the external power brick is chunky. But for a clean dual-monitor workflow at a reasonable price, this is the pick.
What We Like
- Native dual 4K@60Hz support — no DisplayLink needed
- UHS-II SD and microSD readers (fast for photo/video)
- 2.5GbE Ethernet for fast wired networking
- 96W power delivery charges any M4 MacBook Pro
- Stable on M4 Macs — no display dropouts
What We Don\’t
- HDMI 2.0 only (no 120Hz or 8K support)
- No DisplayPort output
- Power brick is large and heavy
- Only two USB-A ports (some users want more)
Comparison Table
| Product | Price | Connection | Power Delivery | Display Support | SD Card | Rating |
|---|---|---|---|---|---|---|
| CalDigit TS4 | $379.99 | Thunderbolt 4 (40Gbps) | 98W | Dual 6K@60Hz | UHS-II | 9.5/10 |
| Anker PowerExpand 5-in-1 | $49.99 | USB-C 3.2 Gen 2 (10Gbps) | 100W passthrough | Single 4K@120Hz | UHS-I | 8.7/10 |
| Plugable UD-ULTC4K | $179.99 | Thunderbolt 4 (40Gbps) | 96W | Dual 4K@60Hz | UHS-II | 9.0/10 |
How to Choose
Thunderbolt 4 vs USB-C: If you need dual monitors, fast external storage (NVMe SSDs), or 2.5GbE Ethernet, pay for Thunderbolt 4. If you just need one monitor and a few ports, USB-C 3.2 Gen 2 (10Gbps) is fine — and much cheaper.
HDMI 2.1 matters if you have a 120Hz monitor. The MacBook Pro’s ProMotion display is 120Hz, and if your external monitor matches that refresh rate, HDMI 2.1 is the only way to drive it at full speed. HDMI 2.0 caps at 60Hz. The Anker PowerExpand 5-in-1 and Satechi Slim Hub Pro both support HDMI 2.1; the CalDigit TS4 and Plugable UD-ULTC4K do not.
SD card speed: UHS-II readers (300 MB/s+) are essential for pro photographers and videographers. UHS-I readers (104 MB/s) are fine for casual use. Don’t pay extra for a UHS-II hub if you only shoot JPEGs.
Avoid DisplayLink docks for M4 Macs. DisplayLink requires software drivers that can conflict with macOS updates and introduce latency. Native Thunderbolt 4 docks are now stable and widely supported. If you need three monitors, DisplayLink is your only option, but for two monitors, go native.
FAQ
Will the CalDigit TS4 work with an M4 MacBook Pro?
Yes. CalDigit released a firmware update in late 2025 that ensures full compatibility with M4, M4 Pro, and M4 Max chips. MacRumors forums confirm no issues.
Can I use the Anker PowerExpand 5-in-1 with a 16-inch M4 Max?
Yes, but the 100W passthrough may not charge the 16-inch M4 Max at full speed under maximum load (it needs 140W). For normal use, it’ll charge fine.
Does the Plugable UD-ULTC4K support 8K displays?
No. The HDMI 2.0 ports are limited to 4K@60Hz. For 8K, you’d need a Thunderbolt 4 dock with DisplayPort 1.4 (like the CalDigit TS4) or a hub with HDMI 2.1.
What’s the difference between Thunderbolt 4 and USB-C?
Thunderbolt 4 offers 40Gbps bandwidth, dual 4K display support, and mandatory 100W power delivery. USB-C 3.2 Gen 2 caps at 10Gbps and single 4K display. Thunderbolt 4 is backward-compatible with USB-C devices.
Do any of these hubs support daisy-chaining?
Only the CalDigit TS4 supports Thunderbolt daisy-chaining (up to 6 devices). The Plugable UD-ULTC4K has one downstream Thunderbolt 4 port but daisy-chaining is limited. The Anker PowerExpand 5-in-1 does not support daisy-chaining.
