Are there other laptops/chargers out there that support USB PD 3.1 EPR? Curious how those efficiencies compare.
It appears the Macbook charger gets about ~93% efficiency at ~100W load, and 87% efficiency at ~27W load. No metrics on the 140W charging I can find, though.
MBP 16 inch in 2021 was apparently the first PD 3.1 apple charger
