Its not like a iPhone and needs more power hence the bigger adapter. If you have it plugged into a computer it will charge very slowly, only if asleep and you aren't using it.

It does charge but very slowly. The USB from your computer does not put out enough juice to charge it as quickly as the wall charger.

Might shorten the life of your charger, but it shouldn't hurt the iPad. That, and it will take forever to charge.

I believe because the USB port you are using is a low power one. I don't have problems with my computer, charges fine, slower than outlet of course but not terrible.

This will make it charge. It works flawlessly on my Win 7 machine.

Puleeze.... The iPad needs one amp for charging properly. The standard USB port is rated at half an Amp. Why risk damage by overloading the USB port?? Even if some silly software can make it work??

Use the right charger.

iPhone charges slow enough via USB compared to on the wall, I think the iPad would take far too long even if it did charge through USB

Most computers won't charge it but macs will. My MacBook air is what I use to charge my iPad 2 and it charges fully from near 0% in about 2 hours or les I'd guess. I'll have to let you know when I run it dead tonight. I'm at 78% now so I'm no where near dead, lol.

I guess you need to go out and buy a mac. Darn right? Haha!

Lmao if they set the max to .5 A why would they put it there if it could damage your port??

It doesn't charge because your mobo doesn't allow for greater power draws. More expensive motherboards allow for 1A to be drawn, charging the iPad. Like my pc. Why do you care anyway? Lost your iPad charger? Just buy any 5V adapter. Just make sure it puts out 1A or more.

iPad wants 2A. You can use anything less or anything more thn 2A. Just make sure it's the same voltage.

If you are on a Windows machine there is a good chance the USB port isn't powerful enough to charge it. This was a BIG fiasco at work when the iPad was introduced. Employees were trying to charge them via the HPs and Dells we had and they wouldn't charge.

However, that being said many machines had a fix released that would allow more power to the USB (I forget the specifics but if I remember correctly Asus had an article about it on their website which is how I learned about all of it).

Your computers website may have the information, but if not your motherboard manufacturers should.

Each USB port is suppose to support up to 0.5A. Some manufacturers try to skimp by multiplexing multiple external USB ports onto one USB slot on the motherboard. Essentially 0.5A ends up being divided among the multiplexed ports. Normally most devices like USB drives and card readers don't draw that much current, so you can use multiple of them simultaneously and not have problems. However with the iPad, it needs at minimum 0.5A. So if you want to charge the iPad, then you'll have to disconnect other devices plugged into these multiplexed ports.

It is also the same reason why external USB hubs without an external AC adapter doesn't charge the iPad either.
