Does this work if plugged directly into power (to charge phones) or must it be plugged into pc to recognize?

By "work" if you mean to transfer information or connect a device, then it must be plugged in to your computer.

Hi J. I've tested this with an iPhone charger/5S and it does not transfer bus power thru the hub. The USB handshake can not accommodate multiple pieces so i suspect this will be the case with any USB powered android as well.

I have an Android phone and it did indicate charging when I plugged it into the USB Port with the phone manufacturers cable.

Yes it works just like charging your phone with a usB charger to your PC. It's slow , nothing like charging directly to power outlet

It only charges through the power adapter provided. The USB port is data only & does not support the power functionality of USB.

I don't know!! Sorry, but mine's been plugged in to an outlet the whole time I've had it. PC

This charges by plugging into your wall outlet with the battery inserted (removed from the phone). A PC is not needed. You can also use this as a replacement for your original charger and charge the battery while it is still in the phone by plugging your own USB-to-micro-USB cable into this charger and your phone. It has a standard USB port, not a micro USB, on the bottom of the unit.

There are 2 power sources. You can either plug in to USB or the wall for it to work.

it gets power through USB. So, when you connect to a computer or a powered usb hub, it works. When you don't, you need to connect to the "charger box".

Yes and it plugs directly into your computer. No electricity needed. Turns on when you click open the ScanSnap Icon on the desktop. It is more simple than you can imagine. Let me know if you have any other questions.

Change your USB Cable! Sometimes using a data transfer cable for charging purposes can give you only USB power. I noticed sometimes also when trying to connect my phone to the PC using the charging cable, the data cannot be read or not recognized by Kies! So I'm guessing that even though they look similar there are 2 types of Micro USB cables, one optimized for charging, and the other for Data transfer. Mine did not come with a cable, so I used my own, and it works fine.

i'm not sure exactly what you mean by this question, but, if the power to the port is off, the computer will not recognize the devices connected to that port.

Its just a converter. It will put power to any cord you put into a usb port. If you can plunge it intoa computer port and charge it will do the same.

Yes, the built-in USB, when plugged into a PC or laptop recharges the rechargeable battery. The power to the PC or laptop, of course, has to be on.

It appears to work powered by the AC adapter or the USB 3.0 cable alone. My USB 3.0 external hard drive works without the AC adapter. However in order to charge attached devices like my mobile phone, the AC adapter has to be plugged in.

This was a gift for my son, and he said it works without being plugged in, with being plugged into an outlet, and it works being plugged into a computer. I hope this helps.

Yes. Just confirmed on my own device. Charging phone while plugged into laptop. Both phone and Lumsing are showing charge indication.

Yes it has to be plugged into power. No it doesn't charge anything that I have found.
