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. All StarTech.com USB Hubs are plug-and-play, providing easy automatic driver installation that’s Operating System independent.
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. 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). 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 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.On the hunt for a USB hub? We bought the top 11 models to test in a head-to-head showdown to see which are the best for various applications. These devices come in a vast array of designs and styles for all kinds of different purposes. Over the course of several weeks, we used each hub in the lab and at home to carefully inspect them for their ports and features, how well they travel, and their looks. In the end, we identified which models are the best overall, which is the best bargain, which is best for travel, and which are the best for specialized purposes. 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.
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. 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. 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). 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. 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. 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. 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. 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.
