does it come with an ac adapter to power the usb hub? because I want to use it for rapberry Pi

Yes there is an AC adapter with the unit. I believe the output is 500ma/ port.Do not know the requirement for Raspberry PI computer board. Other comments indicate it is usable.I use it as a port for my wireless mouse w/o any power other than Dell 660 usb port.

Yes it came with an AC adapter. I don't have a raspberry Pi, so I don't know if it fits into it.

Yes, there is a power adapter with the unit. I did not try to power my Pi with it though.

No, it does not. It won't function as a hub without the power source either (at least not to devices that require power, eg, my WiFi card)

It comes with a USB cable, but it doesn't come with an AC adapter. I use the same one that I use for my cell phone. If you don't have one, USB adapters are easily purchased. It seems to run on a charge for a longer time than expected. Hope it works for you.

AC adapter provided.. Otherwise, you can purchase an AC plug with USB ports.

No, it does not come with an AC adapter. It is powered by the USB connection. I have had no problems with just using the USB connection as a power source.

Yes Fedora23 use this adapter New Premium External Power Supply 5.0v 2.0A (2000mA) AC/DC Adapter for USB HUB. hope this help it is what I use and I have a red 7 port hub as well

Mine came only with a USB cord, no AC plug. Good luck -- it seems to be inconsistent!

The raspberry PI cannot get enough power through it's usb ports. You will still need to power it through it's power port. Fortunately, because this hub provides 500ma per USB port, you can then plug the power cable into this hub as well (leaving 3 remaining ports for your devices) and you won't seed a separate power supply for your Raspberry PI.

That other answer is not entirely correct. A powered hub can operate on USB power only. It does not NEED to be plugged into AC. It will work the same as an un-powered hub, which will limit you to a total of 500mA of current draw from all ports combined. However, if you use the AC adapter then you will have up to 500mA per-port (2A total). So if you are only going to connect low powered devices, or self powered devices, then the AC adapter can be considered optional. If you need to connect devices that draw more power (portable hard drives, USB powered scanners, burners, etc.) then you would need to use the AC adapter to supply the additional power.

It came with a power supply. I do not remember if it came with a usb cable, it uses a standard usb cable.

No, it doesn't come with an AC adapter. It only includes the USB charging cable that connects to your laptop, desktop, battery pack, wall or car charger.

The hub can be powered by the AC adapter and or USB. I have one and I use it to dj. It is nice because if my computer looses power my controllers stay on because the hub is plugged directly into the wall. Don't get the USB 1.0 version I have it and it is terible. I went back and bought the 3.0 and it works great. I run a USB powered light of it so the on off switches are nice. Hope this helps.

Mine came with a power brick, for what it's worth. I believe that this hub corrupted my external usb 3.0 hdd, and pretty much killed it. Don't know this for a fact but I don't use it anymore.

NO! It is a powered hub. Having said that, I love these puppies. I've got 5 total in use and highly recommend them. (See my earlier review.) on USB 3 items, they'll draw power from their own power supplies and the computer itself, you DON'T ever want to take a chance of burning out the USB on your puter or the device (Like hard-drives) due to a low power situation, EVER!The plugable 7 port hub is lighted to let you know when the device is properly connected and powered, on each port.

You don't need an AC adapter. Just plug it into your computer via USB and it should work. Not that you still need USB power if you're going to use eSATA.

This answer may not be satisfactory, but the unit I purchased did not come with an AC adapter, however I had one (120V) that did work (I save all my old wall wart power supplies). But as it turned out I did not need to use an adapter because the unit gets its power from my PC through the HDMI cable, thus no power supply is connected. Anyway, I've been quite happy with the performance of this unit.

Yes it does. This is a hub that expands one 3.0 or 2.0 USB port on your lap top, PC, Tablet to 7.IItwill supply the standard voltage & amperage to the attached devices, but is not good for charging them. If you want to charge also, pick the unit with the 2 charging ports
