USB continues to be the answer to connectivity and charging for PCs, Consumer Electronics, Display and Mobile architectures. It is a fast, bidirectional, low-cost, dynamically attachable interface that is consistent with the requirements of the PC platforms of today and tomorrow.
Asides from these great features, it also has multiple OS support for use with a wide range of devices including Mac OS, Linux, Windows 11 / 10 / 8.1 / 8 / 7 / XP, and many more! And with a 2 in 4 out feature, a small size, and mounting support for easy installation, this industrial USB hub has everything you need for a multiple-device project!

Technically speaking, neither USB 3.2 nor USB 3.1 by itself can deliver video. Using DisplayLink technology, one can convert and compress video into USB data that goes out to a specially-enabled hub or portable monitor. However, few people today use DisplayLink devices. If you have a recent-gen iPad with a USB-C connector, you may find yourself wishing you could connect a USB Type-A device, headphones or even an external display. Anker’s 541 USB-C Hub for iPads has you covered with a unique design that’s meant to snap right into the side of your tablet or even a USB-C laptop. There’s no wire as the USB-C plug and a slight, protruding chin hold the entire metal hub in place. The USB 3.2 specification defines multi-lane operation for new USB 3.2 hosts and devices, allowing for up to two lanes of 10Gbps operation to realize a 20Gbps data transfer rate. While USB hosts and devices were originally designed as single-lane solutions, USB Type-C ®cables were designed from the outset to support multi-lane operation to ensure a path for scalable performance. This industrial-grade USB hub can extend your device's single USB port to four USB 3.2 ports and allows you to switch the USB devices between two host computers (e.g. Laptop and Raspberry Pi).
However, despite the USB-IF's desires, we still see most PC vendors listing their ports as USB 3.2 or USB 3.1, without necessarily telling you what to expect from them. The spec sheets may not even list a generation number, though if they don't, you should assume that it's Gen 1 (5 Gbps).If you're using a USB Type-C cable and port, the charger / host device could support USB Power Delivery (USB PD), which can go as high as 240 watts in some cases. But the wattage has nothing to do with data speeds as a USB 2.0 port could have power delivery while a USB 3.2 port might not. Video Over USB 3.2 / USB 3.1
Speed: Most USB hubs operate at standard USB 3.0 (aka USB 3.2 Gen 1) speeds of 5 Gbps. However, a few can deliver 10 Gbps. There are also some cheapies that are limited to USB 2; avoid those at all costs.Key specs – Upstream connection: 1x USB-C; USB ports: 3x Thunderbolt 4 USB-C 3x USB-A 3.2 Gen 2; Other ports: Gigabit Ethernet, SD Card, 3.5mm audio; Power:135W power adapter; Maximum power load: 90W per port; Dimensions: 190 x 75 x 27mm; Weight: 338g; Warranty: 12 months You can also get other versions of Inatek's USB hub, the HB2025 for example, that connect to your computer via USB-C, which is a more common interface for 10 Gbps connections, particularly on laptops. We really wish one of these hubs had a mix of USB-C and USB Type-A downstream ports, but they are all Type-A downstream. Take some of the claims made by some manufacturers with a pinch of salt. We tested a couple of hubs that promised high-end features but failed to deliver during testing. For example, they might promise 4K at 60Hz, but you might find that this only works on specific laptops and displays. Not every USB Hub is one of the best USB hubs you can buy. We tested a number of other models that are worth considering, but not necessarily at the head of the class. Still, for Windows laptops, MacBook, and Chromebook users who only need a couple of reliable ports, this makes it onto our list of best USB-C hubs.
At 4.8 volts, which is around the minimum voltage most USB devices will tolerate, we got 1.25 and 1.32 amps from the charging and data ports, respectively. When I plugged my Android phone in to charge, a real-world situation because a device will negotiate the best combination of volts and amps, the charging ports sent 4.78 volts at 1.35 amps while the data ports gave the same amount of volts, but just 0.35 amps. To make a long story short, you'll get 6.4 watts from the charging ports, which is decent but not the 15-watts that fast phone chargers provide. All three charging ports should be able to deliver this at once. Obviously, you want USB3+ for anything data intensive. Apart from the speed, it has the added advantage that it's full duplex, so data can flow simultaneously in both directions, like on Ethernet networks or PCIe. Defines multi-lane operation for new USB 3.2 hosts and devices, allowing for up to two lanes of 10Gbps operation to realize a 20Gbps data transfer rate, without sacrificing cable length If you're using an external storage device – perhaps an NVMe drive you've put in one of the best SSD enclosures– you’d benefit a great deal from using a hub that supports 10 Gbps connections – alternatively known as USB 3.1 Gen 2 or USB 3.2 Gen 2. Unfortunately, very few USB hubs actually support these higher speeds and even fewer still support the 10 Gbps speed when it comes from a Type-A, rather than a Type-C, port. HDMI: A hub can be very useful at a desk, especially if you want to hook your computer up to an external monitor. We connected each of the hubs via HDMI to a Philips 272P7VUBNB/27 monitor with the resolution set to 4K, and we used the Blur Busters UFO Motion Test to confirm the refresh rate. Most hubs support only a 30 Hz refresh rate (the image refreshes 30 times a second) at 4K resolution, but a handful now support a smoother 60 Hz rate, and we prefer those hubs that do.Some USB-C hubs go further by incorporating USB-PD passthrough. Here the idea isn’t so much to power the connected devices as to power the laptop the hub connects to, so that you just connect the laptop to the hub, and it charges as you use it without the charger taking up the spare USB-C port. The key thing here is how much power the hub can supply. Most will deliver 80W or more when used with a 100W charger, which should more than cover any laptop. However, with some you’re looking at 50W or less, which might mean missing out on fast-charging modes on some of those laptops that support them. Sabrent's HB-U3CR looks like it was built for MacBooks, thanks to a gunmetal gray aluminum chassis and a stylish, slanted design that will prop it up at an insertion-friendly angle on any table. However, it's an equally strong choice for use with a PC laptop that has USB-C ports and needs a few USB Type-A connections. Anyone who works with microcontrollers such as the Raspberry Pi Pico or any Arduino board knows that most of these devices don't have on / off switches or even reset buttons. So, if you change code and need to restart them or you just want to power them off, you often need to yank the plug in and out, a huge hassle that could damage your gear. But with the Sabrent HB-B7C3, you can just toggle power on whatever port your microcontroller is plugged into. We also did power testing on every powered USB hub. To see just how much electricity the ports could deliver, we connected a MakerHawk Electronic Load Tester to the hub and tried to dial up as many amps as we could. As we dial up amps on any device, the voltage drops, so a 5 volt USB port could drop down to 4 volts or less as we increase the load, but USB devices need close to 5 volts – 4.7 or 4.8 volts is usually enough – so we tested how many amps we could get at 4.8 volts and at the, likely unacceptable, rate of 4.05 volts. All MacBooks and many of the best Ultrabooks come with only USB-C ports, and just a couple of them. That’s why there are so many portable USB hubs that connect to a computer via a built-in USB-C cable and then provide a few Type-A ports, along with some extra goodies such as an HDMI out or a card reader. Anker’s PowerExpand 4-in-1 USB-C hub has one whiz-bang feature we haven’t seen anywhere else, and that’s a built-in 256GB SSD.
