Can you use your iphone charger to charge your ipad? Does it damage the ipad battery or the charger itself?

An iPhone charger puts out half the power of an iPad charger, so at least twice as long, more if the iPad is on at the time. For more info read this: Everything you wanted to know about charging your iPhone or iPad

Hi,My suggestion is don't use the same adapter for iPhone and iPad for charging .The wattage is kind of different for different devices.

Coming to the point I liked doing it at first because the iPhone battery is filling up way faster.But after a week or so I observed that the battery life I am getting is decreased.And my friend also had a bad experience by using the third party adapter and cable which lead to fire and damaged his device.So,Don't Mix and use the adapters and also never go with 3rd party .PEACE

The fact that the chargers are of differing wattages makes no difference. The charger for the device is in the device, not in the thing that plugs into the wall. Changing charger makes no difference to the speed at which they charge. Provided that the power supply can supply enough to charge the device it will work. You must have fooled yourself by thinking that your phone charged faster when you used an iPad power supply.

You can, no damage will result, but be ready for a considerably longer time to full charge. It would be better to use the iPad charger for the phone though.

Yes but it should be the 12watt supply, not the 5 watt, Charges faster

Isn't that what we were discussing, the iPhone charger (all of which are 5 watts)
