Great solid hub and features at a cheap price.

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 a champion with my Raspberry Pi Zero.

I got the USB 3.0 hub because it comes with a 2.5A power supply (otherwise the 2.0 hub would have been fine). The hub has separate power switches for each USB port. Connection details: I have the hub powered from its P.S. The RPi Zero's power jack is plugged into one of the USB ports, and is powered thereby. The hub's USB input is plugged into the RPi's USB port; it has a wifi dongle and a wireless keyboard/mouse dongle plugged into the hub. End result: the RPi boots successfully, it has both a wifi connection to my home network and a working keyboard & mouse with the HDMI display plugged into the tv (but I have ssh configured as well); and there's only a single AC power connection required. And I still have one USB port available, if I need it for something.

5 star and works flawlessly. UPDATED 12/2/16- Still 5 stars.

This 4 port USB hub is being housed in my arcade cabinet. I am using the plug in connecter to power everything but the monitor, and this hub does very well. I have no problems running USB speakers and a raspberry Pi 3 Model B on it, in which the raspberry pi 3 model be in connected via USB to LED arcade controllers and a wireless dongle for wireless (not bluetooth) keyboard. It handles power distribution very well, and hasn't given me a single problem. I will use this brand again. I was initially worried with some of the reviews, but took a gamble, and was glad I did. This powered USB hub performs top notch. ***UPDATE 12/2/16 So I purchased another one of these powered USB hubs. My previous experience was great. I bought this to use with another raspberry pi 3. This time connecting a hard drive, cooling fans, and 2 USB controllers. The pi is finicky with any additional power through the USB ports. This Powered USB hub did not show any signs of power leaking. As a matter of fact, is connects to (plug USB into pi, and power plug into extension cord) great, and works completely as advertised. The first purchase was a risk of the unknown, this time I knew what I was getting, and happily purchased. I am using 2 of these now, one in a Retro-arcade, and on in my home-built retro console. That means they will be closed away, hard to get to, and need to work well. That is why I know choose Sabrent for my powered USB hub needs.

Simple To Install And Use

This is a great switch for both data transfer and power use such as recharging battery powered devices. Rather than plugging in and unplugging devices such as document scanners and printers, simply plug this switch into a computer USB port, plug in the devices, and disconnect them with a touch of the buttons. Constantly having to plug in and unplug devices can wear out the connectors and also increase the risk of breakage. Considering the cost of cables and devices, this product will likely save money by reducing wear and tear on connectors. It is also a quick and easy way to disconnect a computer from the internet, just press the button, and any difficult to stop download is halted just like that.

Needed More USB 3.0 Ports

After have 7-ports in my system already, I still needed more! I was tired of the speed limitations of USB 2.0 and so I plugged this in to one of the on board USB 3.0 ports. It also provided me with MUCH easier access to ports, rather then having to feel around the back of my system for an open port. Also, since it's powered, you don't have to worry about how much power your PSU produces. I had it double sided tape mounted to my power controller for stability and easy access, along with a cable management system. One IMPORTANT thing to REMEMBER is that this is going through an existing port in your system, which means you have to be careful when UN-mounting drives, since they show up as a single unit on the port. * * * Since I bought this I have removed it from my desktop and switched it to me laptop. I replaced it with a 7-port internal card USB 3.0 (which solved the eject issues). I now have USB cables with a variety of end connectors coming out like snakes from my desktop. BUT, I never have to look for a specific USB connector cable again!

Does exactly what it is intended to do

I was a little confused at first because like some of the other reviewers, I thought that the first port was not working. When I plugged in the device to the power the first port did not come on when the button was pushed in. I thought this was a defect, because I noticed when I unpacked it that the first port button was pushed in and I wondered why. However, when I plugged it into the computer usb the light came on. From what I can gather, the first port is powered by the computer usb only while the other three are powered from the wall plug Please somebody (from Sabrent hopefully) correct me if I am wrong about this. So if this is the case, I am fine with it. It is small, lightweight, and I like the idea of the individual on/off buttons for each port. Guess my only complaint would be the lack of any documentation describing this feature. Still giving it 5 stars cause I think it is very well designed and does exactly what it is intended to do and I am 100% totally happy with it.

Fast, practical, and works without a hitch

Works exactly as you'd hope it would. Furthermore, everything connected to it registers very quickly and doesn't seem to take any additional time to process at all going through it, the second you engage the button for whatever's connected to that slot (actually unlike any other USB hub/splitter I've had in the past). Also, turns out, the switches are actually very useful, especially if you don't necessarily need/want to necessarily plug whatever drives/components out after you plug them in but don't want them necessarily showing up/being registered all the time in your OS.

It works with iPad Lightning to USB 3 Camera Adapter!

I bought this for my audio/midi setup with my iPad and it works perfectly. I was able to power 3 devices without powering the USB hub itself, but the iPad battery was draining fast and you could tell it was straining when powering up the 3rd device. Fortunately, I bought the Sabrent hub that includes the power adapter and decided to hook the power up. Once I powered the hub itself there wasn't any more straining when turning on the 3rd usb device. Oddly, the iPad battery still drains when all 3 USB ports are turned on. Fortunately, the Sabrent has power switches for each port and if I turn off two of them, the iPad still charges. Definitely glad I got a hub with switches on each port!

Great product for both macOS and Windows devices!

I bought two for my 2015 MacBook Pro w/ Retina (2x USB 3.0 Type-A ports) as well as one for my wife's 2016 Lenova Yoga (1x USB 3.0 Type-A port). At any given time I have a mouse, two external HDs (Silicon Power Armor 2TB and a Seagate Portable 2TB), thumb drives (PNY Turbo Attaché 256GB), as well as charging cables for various cell phones (iPhone 6 Plus and some Kyocera 3G flip-phone), noise-cancelling ear buds (Bose QuietComfort 20), a universal card readers (Acuvar All-in-one), etc. I have not had any issues with the product thus far. I'm able to move files back and forth between the various external storage media as well as the macOS El Capitan and Windows 10 virtual portions without issue. My only regret is not checking to see if the manufacturer had an item with more than 4 ports...which is why I bought two for my MacBook Pro in the first place! :-)

What a difference a POWERED USB hub makes!

I was having endless problems with my Macbook and its lack of USB pots. I had a few unpowered USB hubs but the lag and intermittent functioning made my life miserable. I had a Bamboo pen tablet and a wireless mouse plugged in, but also my wired headset, and two external monitors. The Macbook could handle all of this, but with the extra demands of two external monitors the one Macbook USB port all of this data was flowing through was choking the entire system. I had only heard of "powered USB hubs" a few times and they seemed like a stupid idea (like I actually know anything about computers after almost 4 decades). Wow was I wrong. I bough this because it was cheap and had a cray amount of positive reviews. I knew instantly (within 5 minutes of testing) that this was EXACTLY what I needed. Okay, so as to the brand (Sabrent). never heard of them. I like the buttons to turn off each USB port individually. I have my pen tablet plugged in but turned off (except when I am using it) by poking a button on the top of this hub. This prevents the Macbook trackpad or external bluetooth mouse from fighting with the pen tablet (in case I wave my hand over the pen tablet by mistake). I suppose I could have two microphones, or two or three of anything and just turn on the port of the one I want to use. The "on/off" buttons for each port really allow you to be creative with what you want to do with this. In fact I read in the manual that you can daisy chain over 100 ports (25+ hubs) if you had an impossibly large number of USB devices you wanted to have instant access to. I am glad I didn't get a USB hub that does not allow me to turn off or on ports instantly. I have seen the light and feel compelled to sing the praises of this wondrous invention. I am also feeling kind o stupid for doubting the awesomeness of a powered USB hub in the first place. Anyway, i hope this helps. Thanks for reading it.
