Do the USB ports provide power? I'd like to know if I could use the USB to power a raspberry pi b+

Yup, I use it to charge my cellphone while I'm working /surfing the Web. I can have my phone close by not have to take away outlet space from my power strip. Also the remotes that come with the screens can operate other Samsung TVs as well.

Hi- I am sorry I cannot answer your question. The TVs were returned because they were not compatible with the wall mount bracket my customer requested.

Yes, and that was the main reason I bought this. I run my Pi, an external HD powered by this, and a WiFi dongle from the hub, have not had any power issues so far (over 6 months running).

It requires auxilliary power. USB won't power it. But it comes with a power pack.

Technically, the answer is yes; it gains its power externally--it has no internal power source. However, in common parlance the answer the answer is no, since it gains its power through the usb and does not have a separate power cord or connection.

It requires a USB 3.0 connection on your motherboard. There are no other power requirements. It is not compatible with USB 2.0 motherboard connections.

This is a simple device that will allow you to get a device online via usb works great as far as I know raspberry pi does not have any USB ports but theoretically if the device you plug the raspberry pi into has usb capability then I suppose it's possible but I can't say otherwise good luck

If I understand you right, yes. The hub is powered and will provide power to any thing plugged into it (optical mouse, keyboard, Thumb drive). The 2 "high" power ports are for fast charging something but does not fast charge if the hub is connected to a PC. They supply the usual USB voltage.

It depends on the enclosure. Some enclosures are capable of powering the drive with just the USB.

I can plug it directly into a USB port but just to provide power I believe you still need to use the SD card

No, power is only needed when using items that exceed your computer's usb maximum millivolt output.

There is no USB power input on this unit. Power is supplied and the internal battery charged by the supplies power supply/plug. If your USB Battery had the appropriate plug adapter, I could see that working though. Hope this helps.

Does the USB 2.0 port provide enough power for the external HDD? Or should I make sure to use an external HDD that has its own power source?

I use mine with just 1 USB port for power, but apparently it depends on the drive you are using inside the enclosure. I use it for the 'old' drive in a laptop. I upgraded the internal drive and took out the 250Gb drive and put it in this case as a back-up drive.

A USB port uses a max 500ma of +5vdc power = 2.5 watts. Thanks for using AnswerParty!

USB ports can only supply limited DC power. Sometimes a two or three port passive (no power supply) USB hub can be useful, but don't expect a seven port hub to operate without a separate power supply. If you're inventive, you can construct a battery power supply with parts from Radio Shack so that you can occasionally operate away from utility power.

No it doesn't. In most cases the PC USB supplies the Power. It probably won't work on a USB on a Multible Hub Distribution Center such as ULTRA as an example!If you own a PC older than 6years, there may not bee enough PC power.

When I tried to pull that much current through this hub... it shorted out, and destroyed every usb peripheral that was attached to it. I believe by the power ratings it might work... but i wouldnt risk it.
