If it is a self powered hub--Yes. If it is powered from the computer and is trying to charge multiple devices at the same time--No or it might charge very slowly.

Yes, and since it has two USB outputs you can charge two devices. Even when it's plugged in

Hi Peter Yes, you are quite right. I hadn't tried that but my unit will not do both at the same time. In practice I have a dual USB charger so the need has never arisen. Regards Richard Allan.

The way I've done it is just plug a USB cord into each of the two ports. One USB is a higher charging power than the other. I've had good luck charging two things at once.

I see no problem with both being connected at the same time. Small charge is delivered as needed to keep battery charged. USB adapter would never notice.

yes. its a great device that allows several plugs of varying sizes to be charging at once.

Yes, it can charge the phone at the same time. Use the turn on the "location" button, and the "car mode" button and use it hands free!

yes, it charges both at the same time. first it will charge the case and then it will charge the phone. I charge them overnight and always wake up to both units fully charged

Yes. I don't know if charging time is longer when both are connected though.

Hello, yes you can charge 2 devices simultaneously. If you only use the blue 2.1A output, then the output current is 2.1A; and if you only use the 1A output, then the output current is 1A; if you charge 2 devices simultaneously, the total output is 2.1A.

It charges at the same time, if you have it open. It will charge itself slow than it will charge the phone though.

Yes, I powered both my ultrabook and my iphone 4 at the same time while charging. The charger was able to maintain the battery at 100% with those two devices plugged in.

yes it can be used while it is charging, if it is on and synced before you plug it in to charge, then you will have to turn it on and re-sync after you plug it in, As pluging it in to power will turn it off. But once it is charging and the power is on and it is synced it will work fine and charge at the same time.

No. It can not be charging and used at same time. It holds a charge for almost 8 hrs of continued use.
