There seems to be one port especially for charging. So how much power does this port provide? And how much power each of the nine other ports?

Each port should be able to out put near 900 mAH. The last port is able to do 1.0 amp for charging tablets or smartphones. It is able to do this because the chipset within the last port is designed to act as a standalone charger, where as the other ports can charge but they are meant for devices/data transfer.

I ordered one and it has two USB ports, HOWEVER, I have been unable to charge two devices simultaneously (I tried with iPhone and iPad and was unsuccessful).

The three outlets and 2 usb ports all work at the same time. We typically charge two phones and two tablets at once.

Unfortunately you already answered this question. Yes, it will require two separate ports to power this device.

Hi Bryan F. Ritter, There is only one charging port and that is the 5V 2.1A Smart Charging Port. The other ports are used for data-transferring purpose only, which can not be served as standalone charger. Meanwhile, for the charging port, when your computer is off but the supplied power adapter is still plugged, the one charging port can still used to charge your device.

The specs provide the information you are asking. It provides 2.1A per port simultaneously which is enough to charge two ipads at the same time as quickly as if you were using two individual ipad chargers. In practice, it seems to work as advertised although I don't have any way of measuring the output while both units are charging.

It does have a USB port, but it is one of the small newer one (micro USB?) and is used to charge the battery in the unit It never occurred to me that it might also be a source of power for other units. I am curious to see if someone responds who does know.

Yeah, two actually. One with a single charging cord, and another which splits into two. So with both charges you could power all three.

You need to use a power adapter. Several of the ports no longer function (side note).

All multiport USB chargers will split the power between the ports but this one is 3A. One port will get 2A and the second 1A so it is sufficient to power all new devices that require 2A charge (like iPad and large screen smart phones) and use 1A port to power second device without compromising on time. Just make sure to use original device cable.

I really cannot give you a definite answer, I have several items that need to be charged and it works. I can charge my phone, cameras, etc on that all at the same time.

Easy. ianker.com (mfr) explains that the white model has ports that handle up to a max amperage but only that specific port. This is "smart" and will handle as much as the device asks for regardless of the port you pick. I have not seen a port max - they imply 8. Some devices must have a minimum amount so with the white model you had to pick the correct port when plugging in an iPad or it would not charge. I think this has a bit more future proofing than the white one so I'm getting it instead.

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.

I believe so. The charge only port works even though no devices are connected to the other ports.

Total = 750mA both ports combined. This isn't suitable for charging more than one modern phone at a time (It's very under-powered.)

MANUFACTURER ANSWER: Thanks for asking! I'm not sure I understand the question? The main power source for charging? For connecting multiple devices to your tablet? -- If you can comment back to this with information on what tablet you have and what you plan to use this hub for I can try to clarify.
