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. HTTPS, FTP, SFTP, TLS 1.2, SMTP, SSH and CLI for web management; remote management via Digi Remote Manager The USB has had multiple upgrades since it first came out, with each iteration introducing vast improvements and new features. USB 1.0s are generally not found much these days unless you have a somewhat ancient device, so the models you need to focus on run from USB 2.0 to USB 3.3. A USB splitter refers to a simple device that splits a single USB port into multiple ports, allowing you to connect multiple devices simultaneously. This type of splitter doesn't typically have its own power source and relies on the power provided by the connected computer or laptop. USB splitters are often used for basic connectivity needs and may have limitations in terms of power distribution and data transfer speeds.

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. 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. 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. 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. 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.

Specifications

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. 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. 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). 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 – just works.
