I would like to use a tool that looks more like an "analyzer" that would display real time data rate transfers. 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. 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. 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.

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. 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. 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. 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.

I have been using the Sabrent HB-BUP7, the nearly-identical 7-port sibling to the HB-B7C3, as my daily driver for more than a year, and having these buttons is a real game changer. Changing default audio devices in Windows is a royal pain, requiring one to go into the control panel to, for example, make sound come out of your headset instead of your speakers. But with the power switches, I just turn off my USB speaker and turn on the wireless headphone dongle, or vice versa. Upstream connection (Type-A or Type-C?): USB hubs have multiple downstream ports to connect to your devices but only one upstream connector, which could be a port but is often a built-in wire that connects to your computer. Many laptops, including a lot of the best Ultrabooks, only have USB-C ports, so your hub's upstream connector would have to be Type-C. 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. 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. We also like the choice of cables, with a short, pull-out cable that stows inside the case for travel, plus a longer desktop cable for when you need to stretch a little further. It gives this unit a little more flexibility than other USB-C hubs. This beast is almost 9 inches long and weighs 1.8 pounds. Every port has a power switch and a bright blue LED indicator. You can turn ports on and off individually, and the light will tell you what’s powered and in use. It’s plug-and-play compatible with PC, Mac, and Linux systems. It has a built-in surge protector to keep all your devices and the hub safe and secure from electrical failures.

If the number of ports is your biggest concern, the Acasis 16-port USB hub is one of the biggest. All 16 ports are USB 3.0, and they all support fast charging up to 2.1A and data transfers up to 5Gbps. There are no compromises, no ports left behind—just full functionality across the entire unit. There are also seven- and ten-port variants if you want something slightly smaller.USB Hubs expand the USB connectivity of your organization’s desktop, laptop, or other USB-enabled host device by connecting multiple USB peripherals to a single USB port. This UGreen unit is another basic USB hub, with four USB 3.0/3.1 Gen 1 ports connecting through a single USB-A connection. Disappointingly, what looks like an aluminium casing turns out to be plastic, which feels a little creaky in comparison to some models, but it’s robust enough for daily desktop or mobile use. The big advantage this one has over similarly priced rivals is a 5V micro-USB input, meaning it can charge devices while in use (without any fast charge support) and run one or more USB SSDs or HDDs – we tried it with one of each without any issues. The only downside? You’ll need to supply your own charger and cable, but it’s hard to grumble at this price. 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.

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. Note—USB splitter is bus powered, requires no additional AC power. This hub is intended for low or self powered devices. Not compatible with automotive USB ports 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. We also connected an Android phone to the ports and recorded how many volts and amps it received. The phone charging test was probably the most realistic as it showed what kind of volts and amps a real device would negotiate with the hub.

Two Ports in One—This USB adapter has a clean and compact design. Standard USB hub splitter enables two devices to share a single available USB port with full USB 2.0 compatibility and performance Best of all, you get three display outputs, with a single 4K/60Hz HDMI 2.0, a lower-spec HDMI 1.4 and a 1440p-capable DisplayPort, giving you the option of using two or three screens at the same time. It might have been nice to have a faster 10Gbits/sec Type-C or Type-A port for your storage, but for connecting a laptop to a desktop setup, this is one of the best hubs around. 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.
