Best USB-C Hubs for Apple iMac 24-inch
The 24-inch iMac is a design marvel, but its “form over function” port placement is a genuine headache for photographers and editors. Having to reach around the back every time you need to plug in a thumb drive or an SD card is a workflow killer. I’ve tested dozens of setups to find the perfect balance of speed and accessibility. While several options exist, the Satechi Clamp Hub remains my top recommendation for its seamless integration and reliable throughput.

Best USB-C Hubs for Apple iMac 24-inch: Detailed Reviews
Satechi USB-C Clamp Hub View on Amazon
If you value aesthetics as much as utility, the Satechi USB-C Clamp Hub is unbeatable. Specifically designed for the 24-inch M1/M3 iMac, it clamps securely to the bottom of your screen, bringing three USB-A ports, a USB-C data port, and UHS-I card readers right to the front. In my experience, the build quality is exceptional, featuring a brushed aluminum finish that mimics Apple’s own hardware. While the data speeds are capped at 5Gbps—which is plenty for mouse receivers or standard external drives—it’s not ideal for high-end NVMe editing drives. However, for photographers who constantly swap SD cards, having that slot front-and-center is a massive quality-of-life upgrade. The clamp mechanism is gentle and won’t scratch your bezel, making it a permanent fixture in many creative setups. It’s the hub Apple should have built into the stand itself.

Anker 555 USB-C Hub View on Amazon
The Anker 555 (formerly PowerExpand) is the “workhorse” of USB-C hubs. For users who need more than just accessibility, this hub offers 10Gbps transfer speeds across its data ports. When I’m moving 4K video files from a portable SSD, those extra gigabits make a world of difference compared to cheaper 5Gbps hubs. It features an 8-in-1 design including an HDMI port that supports 4K@60Hz—crucial if you plan on running a secondary monitor alongside your iMac. The hub does dangle from the back port, which isn’t as “clean” as the Satechi, but the performance-to-price ratio is unbeatable. It also includes an Ethernet port, which is a lifesaver if you didn’t opt for the Ethernet-enabled power brick from Apple. It runs a bit warm during heavy use, but it’s a reliable tool for any digital creator.

UGREEN Revodok 105 View on Amazon
If you just spent your entire budget on the iMac itself and simply need a way to plug in an old printer or a wireless mouse dongle, the UGREEN Revodok 105 is your best bet. It’s incredibly compact and offers four USB-A ports alongside an HDMI output. While the USB ports are limited to 5Gbps and the HDMI to 4K@30Hz, it performs flawlessly for basic peripherals. You won’t find premium aluminum construction here—it’s mostly high-grade plastic—but it doesn’t feel flimsy. I often recommend this to students or home office users who don’t do heavy data lifting. It lacks an SD card reader, so photographers should look elsewhere, but for simple connectivity expansion, it’s the most cost-effective way to regain the ports Apple took away. It’s a “set it and forget it” device that gets the job done without any fuss.

CalDigit TS4 Thunderbolt 4 Dock View on Amazon
The CalDigit TS4 is less of a hub and more of a total station for your desk. If you’re a professional editor working on the 24-inch iMac, this is the gold standard. It utilizes Thunderbolt 4 to provide a staggering 40Gbps of bandwidth, allowing you to daisy-chain high-speed RAID arrays and multiple monitors without a hint of lag. I find the front-facing UHS-II SD 4.0 card reader to be its best asset for photographers—it’s significantly faster than the readers found on cheaper hubs. With 18 ports total, including 2.5Gb Ethernet and multiple 10Gbps USB-C ports, it effectively turns your iMac into a pro-grade workstation. It is expensive and requires its own bulky power brick, but for a professional environment where time is money and connection stability is paramount, the TS4 is the only serious choice.

HyperDrive iMac 24″ USB-C Hub View on Amazon
HyperDrive took a unique approach to the iMac 24-inch by including seven interchangeable faceplates that match every possible iMac color. Like the Satechi, it clamps to the bottom of the screen, but it offers a slightly different port selection, including two USB-A 5Gbps ports and a USB-C data port. I’ve used this hub in a studio setting, and while the color matching isn’t a 100% perfect texture match, it’s close enough to look native from a foot away. The inclusion of a 4K@60Hz HDMI port on a clamp hub is a rarity and a huge plus for those wanting a clean desk with a second monitor. The only downside is that the plastic faceplates can be a bit finicky to snap on, but once they’re in place, the hub looks fantastic and performs reliably for daily tasks.

Frequently Asked Questions
Will these hubs slow down my iMac’s performance?
A USB-C hub itself won’t slow down your iMac’s internal processor, but it can limit the data transfer speed of connected devices. For example, if you plug a 10Gbps SSD into a 5Gbps hub, you’ll only get half the potential speed. Always try to match the hub’s rated speed with your most-used peripherals. For basic tasks like keyboards or mice, you won’t notice any difference regardless of the hub’s speed rating.
Do I need a Thunderbolt hub or just a USB-C hub?
It depends on your hardware. Thunderbolt hubs (like the CalDigit) offer much higher bandwidth (40Gbps) and are required for running multiple high-resolution displays or daisy-chaining professional storage arrays. For most 24-inch iMac users, a standard USB-C 3.2 Gen 2 (10Gbps) hub is more than enough. If you aren’t doing heavy 4K/8K video editing or complex multi-monitor setups, you probably don’t need to pay the premium for Thunderbolt.
Can these hubs charge my iPhone or iPad?
Yes, most USB-C hubs can provide power to smaller devices. However, the amount of power depends on whether the hub has “Power Delivery” (PD) and if it’s connected to an external power source. Clamp-style hubs usually draw power directly from the iMac and may charge slowly. For fast charging, look for a hub that allows you to pass through a USB-C charger or one that has its own dedicated power supply.
Will a clamp-on hub damage my iMac’s screen?
High-quality clamp hubs like the Satechi or HyperDrive models are designed specifically for the iMac’s dimensions. They feature rubberized padding and tension screws that are designed to grip the aluminum chin—the part below the screen—rather than the glass itself. As long as you don’t over-tighten the screw, there is very little risk of damage. Just ensure the “jaw” of the clamp is clean before attaching it to avoid scratches.
Why does my hub get hot during use?
It is perfectly normal for USB-C hubs to get warm, especially when transferring large files or using an HDMI port. The aluminum casing on many hubs is actually designed to act as a heat sink, drawing heat away from the internal chips to keep them running safely. However, if the hub becomes too hot to touch or if you notice your connected devices disconnecting, it might be a sign of a hardware fault or an overloaded circuit.
Final Verdict
For the majority of iMac owners, the Satechi Clamp Hub is the clear winner because it solves the iMac’s biggest design flaw: port accessibility. If you are a professional photographer or videographer who needs maximum throughput for large file transfers, I highly recommend stepping up to the CalDigit TS4. It’s an investment, but for a high-end creative workflow, it’s the most stable and capable dock on the market today. Choose based on your speed needs!
