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. 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. 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. 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 Can you please explain the best testing environment setup? How to establish a solid baseline? Software used. What to use for data transfer.

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. 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. Output ports: Make sure you get enough ports to attach the number of devices you’re likely to need. Most USB hubs have at least 3, more often 4, output ports, but at your desk, you may need a lot more than that. Also, consider whether you are attaching any USB-C devices (most output ports on hubs are Type-A). 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. 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.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. 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. 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. 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.

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. In addition to the SSD, the Anker PowerExpand has an HDMI out port and two USB 3.x Type-A ports that operate at 5 Gbps. There’s a USB-C power pass-through you can plug your laptop’s power adapter – up to a 100-watt unit – so that you can charge your computer while using this hub (the USB-C port does not work for data transfer; we tried). Where I am seeing severe degradation in transfer speeds using USB 3 hubs is from SSD to SSD connected to the same hub.

2 Port Usb Hubs

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 Unlike cheaper hubs, it supports a full 60Hz refresh rate over HDMI, while there’s a Gigabit Ethernet RJ-45 port for when you need a physical network connection. The Type-C and Type-A connections could be faster, with our SSD speeds limited to around 458MB/sec, but this is a great, fully featured hub that’s still affordable and – most importantly – it just works.

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. While all USB ports provide some amount of power for attached devices, the available power may not be enough for certain high-current devices such as USB hubs or external hard drives. High-current devices usually come with their own power adapter, making them self-powered, in contrast to a bus-powered device that draws all of its power from the host computer's USB interface. Bus-powered devices can cause issues if they need more power than is available from the host machine. 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. It's capable of outputting to dual 4K displays (or a single 5K display), has 10 GB/s USB 3.1 Gen. 2 capability, and can charge Thunderbolt 3 laptops with 85W power delivery. It's also designed to be used horizontally or vertically to better accommodate different setups. 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
