I am aware of those you posted above. Did research prior to buying those Apple adapters.

However, explain to me why 13 PM get very warm with the 20W Apple wall wart?

With the 5W brick, this 13 PM is cool to the touch. Both times were inside a case.

What was the temperature difference?

30C feels warm to the touch but it’s nothing for battery.

Idk, it is always very warm with the 20W. Always. Worse if I use the wireless MagSafe puck.

Yeah, with MagSafe 25% of energy is wasted as heat (takes 20 watt but delivering only 15 to phone). 20 watt is almost at limit how fast 13 can charge (22watt max I think), and 5 watt (5V at 1A) charger is super slow in comparison. That’s why in my original comment I said specifically that if you use that charger you’ll be good. How long does it take to fully charge? Must be 4h at minimum?
