No, the iPod will not charge if it is off. The iPod must be on for it to charge.

It will charge faster if the primary ignition is off and the switch is flipped off, but it does not have to be completely off to charge.

You can charge it whilst it's on or off.

You can charge your iPad either way - it doesn't need to be on or off. However, the most effective way is to charge your iPad when it's off. It will charge much faster.

I've never heard of a "charge off bank" but I do know that a charge off account at a bank is where they bank has listed a loan as "uncollectable" and is probably reporting it to the credit bureau as a charge off or "bad debt". Hope this helps
