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

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!

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.

This item works great and is small enough to keep out of site.

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.

I love the individual power switches. Very well made and I use it daily.

Works well. Compact. Looks good on my desktop. One of the switches was twitchy initially. Works fine once operated a few times.

Seems to have solved my wireless USB transmitters from burning out on my Raspberry Pi due to connected HDD load.

Well, it does work. Rating for 5V wall-wart is 2.5a, but it appears that you can’t direct that capacity to a single connection, as it won’t support a Raspberry Pi3+.

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.

Ottimo prodotto, la uso su una tv che ha solo una presa usb. Con questo dispositivo, posso inserire più chiavette, perché alimentato da un proprio alimentatore. Al momento prodotto top!

Zeer goede USB-hub.
