SABRENT 4 Port USB 3.0 Hub with Individual LED Lit Power Switches, Includes 5V/2.5A Power Adapter (HB-UMP3)

Works like a charm.

I am able to connect multiple external drives using the hub and has significantly improved windows performance. The previous hub(s) did not provide enough power to the drive and caused performance issues. Some of them reserved 15W and use the rest of the power for charging devices - even these hubs had problems.

The unit was smaller than I thought. It works fine--needs no power when using with thumb drives. I have two powered drives that I use; in this case, the provided power adaptor also needs to be plugged in--just need another outlet. The only reason I'm giving this four stars rather than five is that while the device works fine with no loss of speed, the ports on the device are spaced to closely to use all four at the same time with certain thumb drives and/or USB connectors. For example, SanDisk Ultra thumb drives would have to be spaced every other slot as they're too wide fit four-up. You may find the same issue with wide USB cable connectors. The spacing between ports needs to be at least an additional quarter of an inch in between or, maybe better, 8-mm more.

So far so good. I'm using this with a Digital Audio Workstation (Logic Pro) on a Mac Studio. I can finally sleep the computer and also turn off my MIDI fader box which has an LED screen which was always on during sleep. I also use this to shut down my TEControl MIDI breath controller and the camera I use for Zoom and Google Meet. I stuck an iLok key in there as well and so far all of it has been working as expected. There is a bit of light leakage from "on" buttons to "off" but for me it's not a problem. (The bright ones are on and the dimmmer ones are off.) if that's the only "problem" I ever have this will remain a true 5-Star product.

This product works great. Like another reviewer mentioned, there are times where coming out of sleep and it is powered, it requires unplugging and plugging back in for the system to detect it. Normally it would be a negative but it happens. Formerly in IT responsible for approving products, there is no perfect product because of the huge amount of possible combinations out there and it shows in product reviews of the product because you will hear of the one combination that did not work. The hub has no problems with 2 other DELLs, 1 HP Envy, or a Lenovo laptop and a dozen desktops just this oddball Spectre. Back to the review: This product works well and the individual buttons are quite helpful. For those really picky about build quality, the blue LED light is only bright on the side facing the ports but the clear ring circles the buttons. The buttons have a little more play than buttons on a PS4/xbox controller. We have 2.5 of these (more later) and the male and female plugs are snug and solid feeling. They all come with unique serial numbers and has a decent build feel to it. The use of the buttons helps wear and tear on cords and plugs since I don't have to pull out USB units I am not using. Since I travel and this laptop, keyboard, mouse, fan, etc. is my primary computer, this inexpensive feature saves wear and tear on $1000+ of equipment. My personal experience is that keeping things on when you don't need them puts more wear and tear on the device and the laptop's circuitry. Another nice feature is that the hub works with or without the power plug. If you just need usb power for your fans without hooking it to a computer, you can use it unplugged. If there is enough power for the ports, there is no voltage/amp difference on which port you plug it into which is a problem on cheaper hubs. (Tested with multimeter) About the 2.5 units, the first one I received threw error messages on my HP Spectre, At that time, I got an email for a review from Sabrent and although I wasn't sure about cause of the problem, they quickly sent me a replacement. The problem was the power brick but I got the replacement with almost no downtime. Pro: Individual buttons helps fine tune power use Can be used as passive power or with optional AC power for devices needing more power Light on active port(s) right on button so you know at a glance versus others on the side or just one light overall Great customer service (May 2017) Con: For the HP Spectre, waking up from sleep sometimes requires reseating plug, not a problem if powering off Lights around button could be more uniform but I'd rather have something than nothing

This 4 port USB 3 powered hub works great for all USB devices such as USB drive, keyboard , mouse, audio interface, drawing tablets, MIDI devices, USB ethernet adapter, etc. So far all devices get detected immediately. I had issues with other cheaper USB hubs (such as NAIO-CHAO with on/off switches) with detection of some devices (audio interface in my case) needing reconnect or switching USB port off/on every time computer started and even with that drawing tablet kept getting unrecognized USB device error. So there seems to be differences in USB hubs on what is used inside as some unknown brands don't perform consistently and can have compatibility issues. Comparatively this is not less expensive device but works flawlessly and highly recommend as a great choice for needing 4 ports with on/off switches. I had similar good result with other USB hubs (without on/off switches) from brands, tp-link and BYEASY. Even though this hub works without power adapter as well for all my devices so far, connecting included power adapter is a good choice to cover all power drawing scenarios and help laptop battery charge last longer. I haven't done speed testing but practically seems no different than other USB 3 hubs. This being 4 port USB hub for portability, USB cable length is fine for most use like next to laptop or wish to be longer in other use. Detachable cable may be helpful in that case. Or use additional extension cable.

I have purchased a few of Saberent products over the years, they have always worked well, good price, and still working, even the packaging is great, can always read the directions if needed, this is a USA COMPANY, WHO HAS NOT MOVED TO CHINA! This company will be my 1st choice from now on, Thank you Sabrent😉!!! Their products just work!

Works well and the disconnect buttons are very handy, hower there is an issue in that it backfeeds power to the host connection. That may work well with most PCs, however on a Raspberry Pi 4 and 5 this voltage interferes with the power controller on the Raspberry Pi and prevents it from booting. You must either disconnect the hub from the Raspberry Pi until it starts booting or remove the power from the hub until the Pi starts booting. Neither is a good solution for unattended operations. The solution is to interrupt the +5V power line while leaving the ground (P-) and the two data lines (D+ and D-) intact. Unfortunately you can't open the case or the plug on the hub to cut the P+ line or insert an isolation diode so the easy fix it to use an inexpensive M/F USB power blocker. With that inline the Raspberry Pi boots reliably every time. This device will work fine as an unpowered hub but in that case you would not use the power blocker. Update: still having issues with the Raspberry Pi 4 booting reliability even with the power blocker installed so voltage must also be feeding back on the host data lines. Had to isolate this hub from the Raspberry Pi with another non-powered hub to get it to boot reliably. Taking off a star for that.

Todo lo que he comprado de la marca Sabrent me ha dejado holgadamente satisfecha. Desde la presentación del embalaje hasta la calidad de la terminación y componentes, son productos «en serio». Este hub ha resuelto una necesidad de comunicación de dos discos USB sobre un router usado como server, que solo admitía un puerto USB de salida. Intenté conectar dos discos de 5T con un hub común, pero no levantaban por falta de potencia. Este hub potenciado permite montar hasta 4 discos USB en la única entrada USB del router, con asombrosa sencillez. Solo enchufar y habilitar cada puerto con su respectivo botón de carga (cada puerto tiene un interruptor individual, algo estupendo). El router levantó los discos al instante sin ningún problema de conectividad, y los discos fueron identificados por la PC como unidades de red individuales, con excelente velocidad de acceso desde otros dispositivos. Es muy pequeño de tamaño, y no ocupa lugar en una mínima mesa o balda donde está el router. Es cierto que el cable es corto, pero para el uso que yo le doy, que es tenerlo al lado físicamente del router, sobra longitud. Se ve de buena calidad y muy buen desempeño. Estoy muy satisfecha y lo recomiendo para cualquier necesidad de hub USB. Vale cada céntimo del precio.

Ich habe 3 SATA Platten mit USB zu SATA Adaptern an einen USB Hub angeschlossen. Leider genügte die Stromversorgung eines normalen Raspberry PI 4 (und 5) für dieses Szenario nur für genau eine Platte. Sobald man zwei anschließt, fällt die Stromversorgung des USB Adapters aus. Die Platten selbst werden über eine eigene Stromversorgung versorgt. Mit diesem Adapter funktionieren alle 3 problemlos, da er eine externe Stromversorgung für die USB Ports hat. Zudem kann man jedes Gerät einzeln ein/ausschalten, wobei die Schalter in ihrer Postion verbleiben (es sind keine Tastschalter).

Wygląda na dobrze wykonany produkt.

Zeer goede USB-hub.

Perfect!
