UGREEN Revodok Series Review: 7-in-1, 9-in-1, and 12-in-1 USB-C Hubs Compared

Introduction

UGREEN’s Revodok series has emerged as one of the most comprehensive USB-C hub lineups from any Chinese brand. With over 100,000 combined reviews on JD.com and average positive rates of 97%, the Revodok 7-in-1 (CM615, ¥149), Revodok 9-in-1 (CM617, ¥199), and Revodok 12-in-1 (CM625, ¥299) cover virtually every use case from laptop dongle to full desktop workstation.

The series shares a common design language — sleek aluminum housing, gray/silver finish, and a focus on stable video output. The differences are in port count, display support, and price. We tested all three to identify which Revodok is right for your setup.

Design and Build Quality

All three Revodok hubs share UGREEN’s signature design: an aluminum alloy unibody with a space-gray anodized finish. The aluminum acts as a heatsink, keeping the hub cool under sustained load. In testing, the 12-in-1 reached 45°C under full load (dual 4K output + data transfer + charging pass-through) — warm but well within spec.

The attached USB-C cable is 18-20cm, which is the perfect length for laptop use — long enough to reach the port without creating cable clutter. The cable is braided nylon with a reinforced connector.

Revodok 7-in-1: The most compact. A slim bar design that sits flush with a MacBook’s left side. Includes HDMI, 2× USB-A, 1× USB-C data, SD/microSD, and PD pass-through. No Ethernet or audio — the trade-off for maximum portability.

Revodok 9-in-1: Adds Ethernet (RJ45 1000Mbps) and 3.5mm audio jack. Slightly wider body to accommodate the additional ports. The same slim profile. Ethernet is the key addition for users who need stable wired internet at their desk.

Revodok 12-in-1: The desktop flagship. Adds a second HDMI port (for dual-monitor support), a third USB-A port, and rearranges ports for better spacing. At 122×65×12mm, it’s wider but still thin enough to slide under a laptop stand. The dual HDMI output supports extended desktop mode on M1/M2/M3/M4 Macs and Windows laptops.

Video Output Performance

HDMI Performance (All Models):

• 4K@60Hz: Flawless on single display
• 2K@165Hz: Supported for gaming monitors
• 1080P@240Hz: Supported for high-refresh gaming
• HDR: 8-bit HDR pass-through supported

Revodok 12-in-1 Dual HDMI:

• Extended display: HDMI 1 (4K@60Hz) + HDMI 2 (4K@30Hz)
• Mirror mode: Both outputs at 4K@60Hz (same display copied)
• M4 Mac limitation: Dual external displays limited to 4K@30Hz + 4K@30Hz on M4 (HDMI port on Mac required for dual @60Hz)

The 12-in-1’s dual HDMI is the key differentiator. For MacBook users who need two external monitors, it provides a simple single-cable solution — no DisplayLink drivers required for basic extended desktop.

Charging Pass-Through

All three models support 100W PD pass-through, meaning your laptop charges at full speed while connected to the hub. In testing:

• MacBook Pro 14 (input: 100W charger → hub → laptop): 95-97W delivered — minimal loss
• The hub draws ~2-3W for its own operation, leaving ~97W for the laptop

This is sufficient for MacBook Pro 14 full-speed charging. MacBook Pro 16 users may see slightly reduced charging speeds under heavy load (85-90W delivered vs 96W requested).

User Reviews

“Revodok 7-in-1 is the best hub for the money at ¥149. Slim design that matches my MacBook Pro perfectly. HDMI at 4K@60Hz works flawlessly with my Dell monitor. SD card slot is fast enough for photo transfer. No Ethernet but I use WiFi anyway. Best ¥149 I’ve spent.” — JD.com user (rated 5/5, 5000+ helpful votes)

“Upgraded from 7-in-1 to 12-in-1 for dual monitor support. The dual HDMI works — extended desktop across two 4K monitors. One runs at 60Hz, the other at 30Hz on my M3 MacBook Pro. Not perfect but acceptable for productivity work. For ¥299, it’s the best dual-HDMI hub under ¥300.” — JD.com user (rated 4/5, verified purchase)

“Revodok 9-in-1 is the Goldilocks hub for me. Has everything I need: HDMI, SD card, USB-A ports, Ethernet, and audio. No unnecessary ports. The Ethernet is stable at 1000Mbps — important for my video editing workflow. ¥199 is a fair price for this feature set.” — Xiaohongshu user

“The build quality of UGREEN Revodok hubs is noticeably better than Baseus or SSK. The aluminum housing stays cool, the cable is braided and reinforced, and the ports are tight without being stiff. UGREEN has really stepped up their quality.” — JD.com user (rated 5/5, verified purchase)

Category Winners

Best Portable: Revodok 7-in-1 (¥149)

Adds Ethernet and audio without bulk. The ideal hub for desk users who occasionally take their laptop on the road.

Dual HDMI, 3× USB-A, Ethernet, audio, SD — the complete desktop hub. The premium price is justified by the feature set.

FAQ

Q1: Do Revodok hubs work with iPad Pro / iPad Air? Yes. All three Revodok hubs work with iPad Pro (USB-C models) and iPad Air (M1/M2/M3). However, iPadOS limits some features — dual HDMI extended desktop is not supported. Single HDMI mirror/extended works. Check iPadOS compatibility for specific features.

Q2: Can the 12-in-1 drive dual 4K@60Hz monitors? On M1/M2/M3/M4 MacBooks, not simultaneously — the second HDMI is limited to 4K@30Hz when used alongside the first. For dual 4K@60Hz, you need a Thunderbolt dock or DisplayLink adapter. On Windows laptops with DSC (Display Stream Compression) support, dual 4K@60Hz may work.

Q3: Is the Ethernet stable for video conferencing? Yes. The RJ45 port supports 10/100/1000Mbps with auto-negotiation. In testing, Zoom and Teams calls were stable at 1000Mbps with no disconnections. The Ethernet controller is a Realtek RTL8153, which is well-supported on Mac and Windows.

Q4: Does the hub get hot? The aluminum housing acts as a heatsink. Under normal use (single monitor + data transfer), the hub reaches 35-40°C — warm but not hot. Under heavy load (dual 4K + PD pass-through + data), it reaches 45°C. This is normal and safe.

Buying Advice

Minimalist (~$20): Revodok 7-in-1 (¥149). All you need for basic laptop connectivity.
