Causes Shorts / Damage to Power Sockets

Quickly shorted out my car's power port, with a 85W device plugged into it.

On my second one it's going back. Both have electrical shorts and you get a slight current short when you touch the top cushion handle and the metal bar. Really a shame as its a nice light but two for two on shorting? Hard to believe there is very little online about this issue which is dangerous

Broke the t50 torx socket the first day while using a breaker bar.

Broke the power socket twice, costing me ~$150 to repair and replace this with a Toshiba brand AC adapter. The inner circumference of the plug is too small for the metal tip in the power socket on my Toshiba Satellite P870. Even though it is able to supply power for a while, after months of use, it eventually puts so much pressure on the power socket that it breaks off, and even a good AC adapter won't work at that point, so the socket has to be re-soldered by a professional.

The power socket farthest from the male pins feels a bit like it may eventually break this device due the the leverage it creates when plugging or unplugging the device. Otherwise a great little addition to any room that people use with phones or other devices, like a living or bed room.

I purchased this device because I was in need, and didn't look at any of the reviews beforehand. It came, I set things up by reading the usbr's manual [sic] and everything worked fine... at first.

About a week later, I noticed that the LED on the AC adapter would go on and off, as if there was a short somewhere. Being the genius that I am, I tried plugging up a hard drive, and sure enough, I could hear the hard drive wind up and down in correlation with the LED going on and off.

The best part is when I reached to unplug the cable so I can box it up as defective, I accidentally found exactly where the short was. The cable wasn't as shielded as I thought, and got a minor electrical burn on the hand. I wouldn't suggest buying this one, folks.

Within just a few days of using this item, it shorted out causing a burning plastic smell. I don't believe it caused any damage to the adapter or port it was plugged into, however, now the item no longer works.

To be clear, my equipment is all plugged into a sinewave UPS battery backup/power conditioner which is plugged into an isolated grounded outlet. When I plugged this unit into my (then working) original Xbox 360, it zapped one of my receiver's HDMI ports, caused a low buzzing noise that is now constant inside the receiver, and wiped out my satellite box, coax adapter and it's looking like it also broke the equipment mounted on my satellite dish. It accomplished all this before my UPS tripped (which was quickly). I may have just lost the quality lottery on this one, but I certainly cannot recommend it, as it destroyed/reduced the value of lots of expensive equipment. Stay away.

This one sit sideways and constantly pull out from socket when too many things are plugged in.

I have been told I can send it back for another one which I will do.

Shocked me when touching my charging phone and other electronics at the same time, do not use. Serious hazard. I do not have this problem with other chargers configured in this way. Touched the phone to the PC case and it sparked.

When using this my outlet always trips and can't use it.
This is not working as expected.

There is a short in the power wire or something.  My box won't stay on..  It's disappointing because I'm out of the return window and I've cut the cable already...

My Wife bought me this for a gift so I am obligated to repair it about every two years. Circuit boards keep burning out. Must happen a lot because they are back ordered and not readily available. Yes I do have transient and surge protection. Hmmmm! Go figure!

I bought this 10 port unit because it was precisely what I was looking for - compact, ports a plenty, and easy to use for those quick plug in needs.  However, the first unit came only partially functional.  Exactly one half of the 10 ports were functional, the rest were DOA.  Amazon promptly replaced the unit (e.g. ordered 2nd, refunded 1st) and I had it on my desk 2 days later.  Everything seemed ok with that unit and I was willing to look past the defective 1st unit.

That brings me to today, a little over 1 month later.  I came into work to find all attached devices acting strangely (power lights going on and off and back on), a sparking sound and a faint smell of smoke.  Currently, as I write this, I am awaiting a disk fix of an attached hard drive that I hope was not irreparably damaged and will be spending the next hour or so testing the other devices that were connected to it to make sure they weren't damaged by this unit.

So, do yourself a favor and look elsewhere for a USB hub and avoid the Cable Matters 10 port usb hub like the plague - I certainly will.

UPDATE:
So far I have determined that this device was directly responsible for shorting out a Wacom tablet, an HP scan jet scanner, a Leap motion controller, and an external WD hard drive -all have to be replaced.  My guess is that the power management failed causing power to repeatedly cycle on and off on these devices leading to them to short out.

As I said, this Cable Matters product is garbage, and dangerous garbage at that.

It works well with my computer, correct voltage, good cord length, etc for my NV52. However, after 2 months I experiences a wiring defect. I now have to jiggle the cord to get it to stay and charge, meaning I cant move my computer at all or it will fall out of place and not charge. The power adapter also gets really hot that it burned me! Be careful! I would not recommend this product.
