Question: Will it charge electronics without being plugged into a computer?  I have one that charges my mp3 but not my ipad or phone unless it plugged into a computer.
Document: I purchased this so I wouldn;'t have to constantly switch sync cables between all my devices. The only issue is my iPhone and iPad do not charge or at least they say they're not charging when plugged into this hub however they sync just fine
This compact and useful addition to my computer bag allows me to download/charge several USB-powered items at once. I've even used it in a pinch to help charge or power multiple items in the car (it's not good when you navigate by iPad and both poop out at the same time in the middle of the desert).
I purchased this because it had 7 ports and a PLUG so I could charge apple devices. Even though I plugged it in, apple device would not charged. I also plugged the hard wired USB cable into the iphone wall charger and still not enough juice to charge one device. I assume it can be used to connect between a PC and USB device. IF YOU WANTED TO USE THIS AS A STAND ALONE USB HUB TO CHARGE DEVICE (S), IT WILL NOT WORK
I ordered this hub on February 20, 2014 and it is working flawlessly to this day. It handles my low and high current usb devices like my display adapter and recording interface without a problem. I decided to order a second one on May 30,2014 and was disappointed with what I got. It would not power my high current devices like the first hub and it would not connect anything to my computer.
I keep the receiver for my wireless keyboard and mouse plugged into it as well as my phone charging cable, and I have found that I can plug USB drives into it and get flawless results, never losing any data in the transfer. What mor can you ask for in a USB hub. One more thing, it also has a cool energy saving power switch on it which also cuts off any power to your USB items when not in use.
Don't buy if u wanna charge ipad, it works Ok when connected with Power and USB to desktop if u need more USB ports
Great USB hub that does its job. Works on almost all the drives I plugged into. Having the AC powered is an added benefit as you can charge your devices with it too.
It allowed me to male my mac mini int omy primary computer with three screens (2xUSB video adapters) and multiple additional devices that the built in controller could not handle. The form factor is awesome as well, accesible without being intrusive.
So far all of my devices are running with no issues, just as if they were plugged directly into the actual computer port. I have Windows 7 and the port synced up with no issues. Highly recommend this!
It works and you get good signal for all USB items. I had a cheaper one and it would not read all the ports. My computer only has two ports so this accommodates my many needs.
Answer: Even though I have not tried it,I would assume that it would being how it does come with its own power source.
