Hi All:

I understand the iPad really needs 2A to charge, and will charge somewhat from a 1A USB connection.

It's less clear to me (and unspecified at Apple's page) what happens if connected to a 0.5A charger, like from many factory car adaptors.

Obviously that does not supply enough juice to run the iPad and charge the battery. But does it provide any juice at all?
- It would seem to me 0.5A is better than nothing
- If the iPad is OFF, then 0.5A should charge it eventually.

I'm asking because I'm trying this, but I keep getting beeping. I power down the iPad, keep hearing beeps, look at the iPad, and it is awake. What the heck is up with that?

Thanks!

You need the right kind of charger. A friend of mine bought one used really cheep once, but the catch was it didn't have the charger. We tried a lower power charger and figured a little power would be better than nothing, but after leaving it on the charger for 2 days it still didn't do anything. We ended up just charging it off of my MacBook until he got the right charger.
