Curious to know your charging efficiency using the MagSafe charging puck. I‘ve just run a test with the newly acquired iPhone 13 (my first MagSafe device) which I drained completely prior to charging;

[Home]
Apple MagSafe puck charging performance (iPhone 13 from 0% to 100%)…
- Using Third party 18w wall adapter (USB-C): 5V=3A, 9V=2A (PD), 12V=1.5A (PD)…

15 minutes: 12% [Powered on in 6m30s]
30 minutes: 31% (+19%)
45 minutes: 47% (+16%)
1 hour: 63% (+16%) 1st hour: +63%

1:15: 77% (+14%)
1:30: 86% (9+%)
1:45: 95% (9+%)
2 hours: 100% (+5%) 2nd hour: +37%

& here’s an earlier 1 hour MagSafe puck test in the car (iPhone 13 starting at 21% charge)…
- Using third party 18w car adapter (USB-C): 5V=3A, 9V=2A (PD), 12V=1.5A (PD)…
•No Apps running, Screen off

1 hour: 21%-60% (+39%)


So how other iPhone 13 owners are going with the MagSafe puck? Are you happy with your charge speeds? What charging brick are you using with it & what’s the brick’s wattage rating?
 
Some interesting extra info I’m getting from my USB meter as the Wattage increases when using the Apple 20w adapter & MagSafe puck.

It’s able to detect the Fast Charge Type & Protocol & this seems to change as the wattage draw increases…
0-9W… “Apple” charge type : No protocol indicated
9-15W… “Apple” charge type : ”Fast/PD” protocol
15-17W… SCP VOOC* : Fast/PD
~17.75W+… DCP** : Fast PD

*SCP = Huawei fast charge Type, VOOC = OnePlus fast charge Type.
**DCP is an older charge type, yet when used in conjunction with PD, it provides over 18W via the Apple MagSafe puck.
