The 180W charger never draws 180W from AC power?

[Christian_Elsner]

The battery charges with 85W max to preserve battery life.

How fast can the battery be charged?

On both Framework Laptop 13 and Framework Laptop 16, the batteries are designed to charge at 1C, and the charging circuitry will only ever charge up to that rate, regardless of the power adapter wattage. That means up to 55W/61W on 13 and 85W on 16. Charging above 1C would require either putting extra wear on the battery that limits cycle life, or using a battery chemistry that has less energy density. There is some loss in the charging circuity, so you’ll need something like a >60W/65W powe…
