Powered USB Hub RSHTECH 7 Ports USB 3.0 Hub with 4 High Speed Data Transfer Ports + 3 Fast Charging Ports,36W 12V/3A Power Adapter and Individual On/Off Switches(A37-Black)

This is just what I needed for use with my telescope. If you plan to use a usb hub for plugging all your astro gear into this works great. I plug my hand controller and guide camera into this hub and it is powered by my portable 12 volt power source . It then goes to my laptop computer so I can use PH2 guiding and also can control my scope mount. I had no issues with it , just plugged it into 12 volt power and then plug it into a usb port on your laptop ant your set. I also like that each usb plug has it's own power button so you can turn things off and on. I velcroed it to one of the tripod legs for use. I have been using it for about 3 or 4 months with no issues. I also like that it also has a usb power port at the top , so you could use it for a dew or whatever if needed... just one last thing, if you try and use a non-powered usb hub for this type of use it will not work, but this powered one works great...

I've bought a dozen USB 3 hubs the past four or five years and half of them didn't work well on my iMac due to constant dropped connections. So I hate rolling the dice on a new hub and struggling with drives dismounting at inopportune times. Thankfully, after a couple weeks, so far so good: an external drive, scanner, audio DAC and LED light all work fine with with the RSHTECH USB 3 Hub. And I love the on-off switch, especially for my LED light and scanner. Plus, it seems well made for plastic (kinda used to aluminum) and has enough heft and size to not twist or fall over with everything plugged in. The wall wart power supply runs cool to boot. Plus, the high power charger port works great with my iPhone: fast charge and no extra heat on the hub. The only small gotcha is the port indicator lights: dim and hard to see due to the use of an angled bevel on the side. Mounting the indicator lights on a flat area on topside would be much easier to see.

I used to expand ability for my PC to connect to additional external SSDs from my USB port. Since the USB port on my PC didn't appear to have enough power to drive multiple drives, I purchased this externally powered USB hub to help drive more power into the external drives. Worked great!I tried using up to 3-SSDs and a USB Stick simultaneously and didn't appear to see any problems. Transfer rate appeared to be pretty good, although I didn't specifically measure any transfer rates. The overall build of the USB Hub is very solid and you can also use the Hub without the external power adapter for devices that are less power hungry.Gave 4-stars since plugging into the Quick Charge - USB slot was a little "snug". Will continue to monitor the reliability but for a few weeks now no issues and has being working very well.

Many, if not most, of the earlier reviews touted this hub's physical characteristics and ability to charge other devices... and rightly so. But, for a variety of reasons, I was more interested in its ability to handle data storage devices which could add enormously to the potency and usefulness of a laptop computer. Bottom line? When it comes to accommodating external disk drives, this hub brings desktop-computer capacity to the laptop. I do not exaggerate here.My tests began by plugging the hub into a USB 3.0 port on my relatively muscular desktop computer. Then, I plugged FOUR WD Portable disk drives into the hub. As I pressed each of its convenient buttons one-by-one, my Windows OS quickly recognized the relevant drive and correctly displayed its folder and file content. Wondering how much this thing could handle, I disconnected one of the drives and replaced it with a non-powered hub which offered four additional ports. As an aside, this hub could not handle even one of my WD drives by itself. In any case, I plugged two drives into this non-powered hub, and both were almost immediately recognized by my OS which again accurately displayed its file and folder content. I didn't bother using the remaining two ports on the non-powered hub. I had no doubt whatsoever about the outcome.But, just to satisfy my curiosity. I plugged my tablet into the charging port on the powered hub. Of course, it worked fine. They say a picture is worth a thousand words. If so, please take a quick glance at the one I've attached to this review. If you ever feel the need to give your laptop access to about 28 TERAbytes of stored data, this combination of hubs will do the job for you quite nicely!Before buying this nifty device, I checked about a dozen others. Best of breed? No doubt about it!-=-===-= ADDENDUM -=-=-=-=Turns out, the foregoing review was a bit premature. The day after I wrote these laudatory comments, one of the hub's four ports failed. The light went out and never lit up again. As if to prove every cloud does, indeed, have a silver lining, I soon discovered another hub which offers all of the desirable attributes of the RSHTECH hub but also features several significant improvements. I somehow overlooked this hub while surveying the field. Thus, my "best of breed" claim also turned out to be premature. At the moment, I'm looking at the new hub which is currently handling, SEVEN WD portable drives while simultaneously charging my tablet and one of my rechargeable battery packs. Here, too, I'm employing the same non-powered hub to provide the additional ports... which I probably will never need or use in the future. But my curiosity needed to be satisfied.

Looks beautiful and performs beautifully. The on/off switches are a great feature and the 3ft+ long USB 3.0 detachable Power Supply cable is the correct length for desktop use. The non-slip rubber base at each end definitely keeps the Powered USB Hub stable and in place. The Led Indicators are passive-looking and not annoying like others display. I wish the Led Indicators were on both sides for if you have it on the right side of your desk, it's easy to forget and not see that you had turned off one of the on/off switches [I have my USB speakers plugged into this Powered USB Hub and turn off that button upon shutting down and often don't realize -- upon restart -- that I had switched off that line]. If I have one extremely minor negative, it would be if you have a USB cord attached to this Powered USB Hub and the USB cord is hanging off your desk, it slightly lifts this Powered USB Hub. Maybe a bit more weight on the bottom could resolve this extremely minor issue. Overall, I'd highly recommend this Powered USB Hub and would buy again if needed in a different venue or location.
