IPad – Will it be fine to charge the iPad with 61W MBP charger

No

I mix and match my chargers often, the only disadvantage is that the iPhone charger charges slower according to a lot of sources, but I have yet to experience it. I still have an iPhone 3G charger I use as a spare at work to charge my iPad on occasion.

Interestingly I have never noticed my chargers getting hot either, but will admit I have never actively looked.

Looking at the Charging Tips here the reason for the slower charge is that the iPhone charger is 5W compared to 10W for the iPad, based on wattage alone, I can't see how you would damage the iPad, I would suspect using a higher wattage might however.

I have found the same problem. Despite using Apple charger and lead the iPad thinks it's a copy and delivers the prompt that my charger or lead is incompatible. I believe the problem is that the voltage in India can waiver because this only happens at peak power usage times.
