With computers nowadays, we have an ever increasing demand for power and so many items use USB. The power that they draw is increasing more and more. We've reached a point where the USB ports on the computers simply don't provide enough power for some peripherals. When you use a USB hub, you are now splitting that already insufficient power down to 25% in the case of a four plug USB hub. Its to the point where many computer people and many instruction manuals for devices will tell you NOT to use a USB hub for certain devices. In order to keep up with demand, a USB hub really needs to provide it OWN power by having a separate power plug that plugs into the wall, not into another insufficient USB of the computer (of coarse this is speaking generally. Some of you PC builders have put in custom hard-core power supplies that are able to keep up better than most, but for the rest of us mortals, our computers are generally not sufficient). The nice thing about this USB hub is that it DOES come with a separate power supply and not a small power supply either. It comes with one that has enough juice to power today's electronics. What's more, it comes with USB 3 and all of its fast speed data transfers as well as USB C connections too. Overall, a great item to have, especially if you find yourself with not enough USB ports on your computer.

Sólido, funcional y hasta estético.

I gave it a 5 star review because it works as advertised. You really don't need a manual as everything is intuitive. Like the two smaller c type connectors for recharging (they work well with iPhone 11). These are clearly marked with the version number. In fact they are all marked with a version number. I bought two of them for my windows and Linux machines. They work well with both Ubuntu and Puppy versions.

When I first started using it I was very satisfied. All of my external hard drives were readily accessible. Recently, I keep having to unplug them and reinsert them into the hub to get them to be recognized. Not sure if it's the hub or my laptop. I just know it's annoying. It's easy to use, and I like the look as well as how it's designed, I just wished it worked consistently. The cord is very long and use is simple. You just plug stuff in and go. The USB cable it comes with was pretty short, too short for my use. I recommend getting a longer one that can handle the appropriate speeds because it does transfer data pretty fast.

Kind of a bummer, this refuses to work on a USB 3.2 2x2 type-C 20Gbs port. It will only work on a 3.2 2x1 type-A 10Gbs port. This is fairly annoying, as my laptop doesn't have any type A ports and it's using the last one available on my main desktop. It's primarily used for my desktop, but this is a major hassle.I've tried 2 known good cables, one is a 3.2 2x2 20Gbs cable, the other is a USB4 40Gbs cable; neither work, nor does the cable supplied in the box. Super annoying. Maybe it's defective, all USB is (supposed to be) backwards compatible. Might have to return this.Update 12/5/23:Returned previous hub and received a replacement the next morning. Good job Amazon!This one does connect to Thunderbolt 3/USB3 gen 2x2 20Gbs type-C ports after unplugging the hub's power cable and plugging it back it, 2 or 3 times (sigh). Same issue with Thunderbolt 4/USB4 40Gbs ports. Resume from sleep does not work, though; the hub ports stay asleep, even with power cycling. The host USB ports are set to allow resume from sleep in the OS and BIOS, and function properly on all the other hubs I have laying around.Tried using known good 10Gbs, 20Gbs and 40Gbs cables, including the one they provide in the box, and my shiny, new Apple type-C cable that came with the 15 Pro Max.So, 5 cables, a Macbook Pro with Thunderbolt 3 and a X670E based PC with built in USB 3.2 gen 2x2 20Gps ports and a 40Gbs Thunderbolt4/USB4 card and another Z690 based PC with Thunderbolt4/USB4 ports.My Thunderbolt attached monitor and Kingston XS2000 external SSD work flawlessly on these ports, so I doubt it's on my end.I also retested an older USB 3.1 5Gbs hub with a Type-C host port using all these cables and it works fine with both PCs and the Macbook. Resume works, too.Strangely enough, plugging the hub into a Type-A USB 3.2 gen2 2x1 10Gpbs port (single lane), it has no problems with connectivity or resume. Also tried hosting my iPhone 15 Pro Max to the hub, which has a Type-C USB 3.2 Gen 2 10Gbs port (probably 2x1 single lane?), and it worked with a mouse, keyboard and various USB thumb drives.Serious weirdness with this hub; doesn't seem to play nice with 2 lane type C ports of any kind. Perhaps they had a bad batch of these things, or maybe it is not really a fully USB compliant device. I'm assuming it's the later. Either way, it's a disappointment.Their product description clearly states it should work:"【2-in-1 Cable】This powered USB c hub includes a 3.3-foot USB-A/USB-C cable, giving you plenty of length to position it wherever you need. The dual USB adapter is compatible with USB-A/USB-C/Thunderbolt 3 devices, such as M1 Mac mini, MacBook, iMac, XPS, Surface Pro and more. Additionally, the powered USB hub 3.0 with ac adapter works seamlessly with Windows 7 through 11, macOS, Linux and other operating systems"Thunderbolt 3 uses 2 lanes, so it should be compatible with 2 lane TB/USB ports.Reducing to 1 star and returning this for a refund.Too bad it's so hard to find a good quality 10Gbs hub that has Type-C upstream and downstream ports.
