I needed a new charger for my iPhone 13 and thought these would be perfect. Plugged in the first one when my phone battery was at about 35% and 15 minutes later, my phone was so hot that I had to unplug it and it was barely above 40%. The brick was plugged into the wall outlet.
Tried the second one and two hours after plugging it in when the phone was at 20% and the phone was charged to 42%. This one was not hot. I left it and TWO more hours later, I returned and the phone is at 68%.
I tried using the cables with other blocks that I have that charge my other devices fast and it was the same result so the cables that come with this are brutally bad. Not fully sure about the blocks.
