Are there other laptops/chargers out there that support USB PD 3.1 EPR? Curious how those efficiencies compare.

- Kirby64 3y agoThe latest Macbook 140W charger is USB PD EPR; It's not 180W, but it's one of the first running EPR. 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.
