Over the years, I've bought several rechargeable Apple products. Between iPhones, iPods, and iPads I have quite a few of the little white square AC adapters. Look in my laptop bag, messenger bag, or one of my backpacks and chances are you'll come across one or more.
Recently my iPad 3 bit the dust and could not be repaired despite the best efforts of the Genius Bar. So I ended up purchasing a new iPad Air 2. When I brought it home & plugged it in, I noticed that at the top left of the screen it said "not charging". After some research, this is what I've learned.
Many of the white AC chargers are 5Watts. These are the most common chargers and that's because iPhones come with them. The iPad 1, 2, and 3 came with a 10W charger. This was because they came with a much larger battery and much faster processor than the iPhones. When the iPad 4 and the iPad Air came out, they had a 12W charger for the same reasons.
When the iPad Air 2 came out, it was sold with a 10W charger. I haven't really heard a rock solid reason why, but speculation is that it has a tad smaller battery, however that is just a guess.
So, the reason I was getting the "not charging" info at the top right of the screen was because I was using a 5W charger. Because all of those white squares look alike, I figured they were alike. Not so much!
Also, many of the iPad chargers that are purchased by users in the after market area are being sold chargers that are 5W or 10W and being used on iPad that just require more power.
I really wish Apple would have let us know about this and made the different wattage chargers different colors or shapes or something.
So there you have it. I went through all of my white Apple squares over the weekend and discreetly marked the power level on them with a Sharpie. I wrote on the side that faces the wall so I'm the only one who knows...
At least I've figured out why I was getting the warning.
