4-Port Powered USB 3.0 Hub, LED Power Switches (HB-UMP3)

I have a 2tb hard disk on my Tablo OTA recorder. It was getting very hot as the disk was pulling lots of power from the USB port. I was having some challenges with recordings especially on long high resolution playbacks like NFL games. I needed a low cost powered hub to take the load off the Tablo. This hub was very affordable and worked great with my Tablo.

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

Works great. Love that you can switch power for each of the attached devices from the hub itself

Friday I needlessly returned this product as defective because when I plugged it into the power adapter the individual port indicator LED's only lit for ports 2,3, and 4 when the corresponding button was depressed. I incorrectly assumed that the device was faulty and asked for an exchange which was thoughtfully overnighted to me. Imagine my dismay when exactly the same thing occurred with the replacement. I had not even bothered to connect the first unit to a USB port because the indicator LED for port 1 didn't light. This time I was curious to see if port 1 would even be recognized when the device was plugged into a USB port and a flash drive installed. I plugged the device into a USB port, depressed the button for port 1 and it's LED lit up. Apparently when connected to the power adapter alone the port 1 LED does not light up and unlike ports 2,3, and 4, only lights up when the device is connected to an active USB port on a powered up machine. It would be nice if that little tidbit of information was contained in a small explanatory note. It would have saved a great deal of time and frustration for both myself and the Amazon rep. I spoke to. Absent information to the contrary one would naturally expect all 4 ports to behave the same at all times. The manufacturers are making things needlessly difficult for themselves, their distributors and end users by omitting any helpful hints in their packaging. Further experimentation has revealed that port 1 does nor receive any power from the power adapter, only from the USB port it's connected to. One of the reasons I purchased a USB hub with a power adapter was so I could charge USB devices without having to have my computer powered up; examples being my Bluetooth headset for Dragon and a flash drive audio recorder. It's nice to be able to charge these devices without the computer running, just don't try and do it on port 1, it won't work.

The Amazon listing is correct and the product does work as per advertisement however, I looked on the internet specifically for a powered usb hub that will work with the playstation vr and camera. Several internet sites listed this particular hub as being compatible with the playstation vr and camera system but the Camera does not work on it. For anyone trying to use vr with the wheel on playstation 5, plug your camera into the ps and the vr into the hub as well as the wheel into the hub and it will work fine.

I have a Dish Network Wally in my travel trailer. I wanted dvr capabilities, so I purchased a one terabyte external hard drive to attach to one of two usb ports on the Wally. This didn’t work. Then I added the plug in powered USB splitter, this allowed more power for the external hard drive to work as a dvr on the Wally. It also made room for my Dish wi-fi unit. It’s compact and allows you to turn on different USB ports. I would recommend using it.

According to AI, it's important to have an external power source, as this Sabrent does. If the only power source is via connecting to your computer, it may not be enough to power some external USB devices. This Sabrent works great, and it was the one AI recommended to work well with a Mac. Very happy.

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.

Ce hub 4 ports USB-A est un vrai produit de qualité : il maintient la vitesse de l'USB 3.2 (5 Gbs) sur les 4 ports, ils sont munis chacun d'un interrupteur et comme le hub a sa propre alimentation (chargeur fourni) il peut fonctionner avec des appareils qui ne sont pas capables de fournir assez d'alimentation pour les périphériques USB, ce qui était mon cas. Aucun Hub USB-A pas cher ne fonctionnait avec mon appareil, celui-ci a fonctionné du premier coup !

Wygląda na dobrze wykonany produkt.

Given the price this is a excellent piece of USB-hub. I have it as a hub for a Raspberry PI4 which is running Zwave dongle and it works as planned. I also have other devices connected to it.

The SABRENT 4 Port USB 3.0 Hub is the unexpected hero of my desk. Plugged it in, hit the little LED switches, and boom my camera stopped flickering like it was trying to send Morse code. Even better, it teams up perfectly with the LINDY 43271 5 m USB‑C to A active extension, like a techy buddy‑cop duo that actually gets the job done. No dropouts, no drama, just smooth sailing. If your webcam is having a meltdown, this hub might just be the therapist it needs.
