Recommend a lightweight USB-C charger

If your battery charge is low, you should be able to get higher than 30W charging.

@nrp

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 power adapter for 13 and a >90W power adapter for 16 to charge the battery at full rate if the system is in standby, or more if the system is in active use.

@Philipp_O Is it possible you’ve only checked the charge current at times when your battery charge was relatively high? Li-ions need to be charged under a charge profile that reduces the current progressively as it gets close to full.

I’m not sure at what charge percentage the current needs to start being reduced for the Framework 13, but I’ve seen li-ion charge profile charts that show current being reduced when the battery is as low as only 65% full. That sounds rather low to me, but I’ve never checked.

So to rule that out, I’d suggest checking the power draw when your battery is 60% or lower.

Welcome to the forum by the way.
