Just had a question as to why the iPad was taking so long to charge so thought I’d re-post this. To check the watts of your adapter look underneath where the very small writing is. (and I mean small!!)
Sometimes when you have visitors they accidentally take your 10w adaptor and leave their own 5w adaptor and all of a sudden your iPad takes 10 hours to charge instead of 4-5 hours.
My advice… Label your adapters. I label them with 5w, 10w or 12w so I don’t get them mixed up.
