- Chargers don’t force an amount of current; the current ratings are the maximum current it’s able to provide while still outputting the rated voltage. As the Framework uses USB-PD, you don’t even need to think about voltages and currents; just look at how many watts the USB-PD charger provides.
- If the charger doesn’t support USB-PD, then you’d be limited to the base USB spec of 5V and it would be really slow (if it works).
