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. 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.

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test. There are still a couple of caveats here. First, your device needs to support a DisplayPort 1.4 video output over USB-C, which will count out many Chromebooks and some MacBooks and Windows laptops. Second, the hub itself takes 15W of power, which means that – even with a 100W USB-PD charger – you may find some laptops not charging at their highest speeds. But if you’re happy to live with these compromises, this is one of the best USB-C hubs we’ve seen.

Similar to the Sabrent HB-U3CR, the Atolla delivered 1.2 amps at 4.8 volts on our power test and it charged our phone at 4.78 volts and 1.35 watts. The Atolla hub also offered similar performance to other hubs; we detected no slowdowns when copying files with our test SSD. Seems the more connections used the lower the speeds, how much will peripheral to peripheral transfers slow down peripheral to computer transfers. 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. The hub supports fast data transfers up to 5Gbps for expanding USB ports or connecting multiple devices. It also has USB on the go and simultaneous transfers across all ports. It’s plug-and-play, and no extra drivers are needed for PC, Mac, or select versions of Linux (2.6.14 or later). An integrated safety chip offers overcurrent, overcharge, overvoltage, overheat, and short-circuit protection for both the hub and any connected devices. It has a power adapter and a dedicated power supply, which makes sense considering it’s so large. It should be noted that both the power and main USB cable must be connected for it to work. The chassis is plastic, so no premium materials were used here, but it’s so big it’s hard to imagine anyone breaking this thing without some serious force. It’s about the size of your average surge protector and measures 7.9 x 2.4 x 0.9 inches.

If you're in the market for a simplistic USB C hub that does everything you need, look no further than the Anker 341 USB C 7-in-1. This model has all the ports most people require for daily use without extras that you'll never use. It's small and portable, so you can toss it in your laptop bag. It even comes with its own fabric pouch to protect it in your bag. It has two USB C ports, two USB 3.0 ports, an HDMI port, as well as a Micro SD and SD card reader. We found this was just the right amount of ports for most people — enough to connect an average amount of tech.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. Powered or not? Some USB hubs come with their own AC adapters so that they can provide more power than your computer delivers from one of its ports. Bus power from your computer can be pretty low, not enough to juice several power-hungry peripherals at once or to charge devices at a reasonable rate. By definition, a USB hub that needs its own plug isn’t very portable. If a device comes with a power adapter, we recommend that the adapter stay connected at all times, otherwise the device may not function as designed. Many of our devices that include power adapters, especially USB hubs, will function in either self-powered or bus-powered mode. However, even though the device may function, each additional device attached to the host computer reduces the total available bus power. If the power runs out, any USB device attached to the computer may suddenly disconnect. If this were to happen to a USB storage device, such an event could result in permanent data loss.

Ethernet is easier, as it’s hard to find a hub that doesn’t support Gigabit Ethernet speeds. That said, a small number now support the faster 2.5 Gigabit (2.5GbE) standard, which isn’t a priority for most home networks, but a plus for advanced users or just for future proofing.

The durable aluminum shell rounds out the features list and offers a sleek look. It matches particularly well with aluminum Chromebooks, laptops, and most MacBooks. The chassis is aluminum, so it’s rugged yet lightweight, and it looks great, too. This is the ultimate hub for anyone who wants to connect several devices or transfer data from multiple USB sources simultaneously. It's worth noting that when plugged into a computer, there is some connection latency for the higher-count ports. But the first four ports are fast and responsive.

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 Despite this, image quality on our 4K display was crisp and free of any fuzziness, and it’s easy to get a working desktop setup on a laptop or tablet. You might want an extra Type-A port with a higher spec, but if you’re looking for a hub for life on the go, this one’s tough to beat for portability or convenience. Example, using a sabrnet USB 3 hub to transfer a 9Gb file SSD to SSD (hub port yo hub port) takes over 9 minutes, while it only takes 15 seconds to transfer to or from the computer.Any extra connectivity? Some USB-C hubs will come with HDMI out, allowing you to connect to a monitor, provided that your PC can output video from its Type-C port. Other hubs have microSD or SD card readers built-in.
