NOOOOOOO!!!!!!! iPad chargers are a higher voltage! Research says that is bad for Li ion batteries

"Li-ion cannot absorb overcharge, and when fully charged the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible."
" Prolonged charging above 4.30V forms plating of metallic lithium on the anode, while the cathode material becomes an oxidizing agent, loses stability and produces carbon dioxide"

Actually, I would recommend it. It charges the devices much quicker. I went out and bought a 12w iPad charger just to be my iPhone charger. I can be on 20% and charge it fully in 40 or so minutes.
The iPhone draws the current it can handle, so there is no harm in using a higher powered USB charger. The 5w chargers that have come with my iPhones are all still in the box.

I'm sorry guys! I just read that article the other day and thought that it would cause harm to the battery 🙁 SO sorry to give bad advice 🙁 🙁 🙁

Don't be too concerned.
Your advice caused no harm just a little confusion.

iphone and ipad charger
It's worth noting that the phone has thermal protection that will shut it down if its internal temperature gets too high, so even if it feels hot it isn't hot enough to damage the phone.

LOL, I've been using iPad chargers since the iPad 1, without any problems. I think you're wrong.

Like I am sure many others, I only use a iPad charger to charge both my iPads and iPhone. Been doing it for years and my iPhone loves it. Do jot think I have used the iPhone charger for any of my phones for years. They sit in their original box, unused.
I could swear there was a very recent thread about the speed of charging and pretty much everyone agreed that since the iPhone only takes so much current from any charger it would charge at the same rate even from those that would provide more power.
