ipad does charge using usb

When I connected my ipad to my computer ( using usb) the battery showed 80%. l unplugged it 3 hours later and the battery showed 100% During that period of time it was tuned off so it does charge using usb. jim+joh

 

It charges just fine as long as the screen in off (sleep mode).

 

Are you guys using macs or pc?
What I caught wind off was that it will charge on newer Macs, but not PC!

 

Engadget has a pretty good article about this:

Apple iPad charging woes: USB hubs, non-Macs and weak ports not rejuvenating -- Engadget

 

Using a PC. Charges just fine, as long as the screen is off.

 

It depends on the age of the computer that you are charging it on as well.

 

My Imac is about 2 years old and charges fast. No problems at all.

 

I always get the warning that I can get faster connections if I use a USB 2 port, but I don't have any.

So far as data transfer speed I imagine the newer 2.0 is better, but what about power level? Is this also increased with a newer 2.0 port?

 

Not all usb ports are equal in redgards to supplying power to peripherals, sometimes utilizing a port in the back of the pc rather than the front will solve the problem. A powered usb adapter can work wonders also.

 

Never thought of the powered hub, good idea. I have an older Belkin 5 port hub for my laptop. This could be a nice alternate when I am at the office.

I will give is a shot tomorrow and see how well it works.
