I have another stupid question on the topic with charging and docking stations.
- Librem 5 expecting 5V 3A
- Docking Station that itself consumes power (for example also 15 W).
- Power supply going to the docking station.
If I use the original Librem 5 power supply to power the docking station, the docking station might itself eat most of the power and so the L5 is not going to get the 5V 3A.
If I use another power supply for the docking station, should I look for power supplies 5V 6A? Or what will happen if the power supply delivers higher voltage to the docking station than 5V? Is the docking station able to transform it to the 5V that Librem 5 requires?
As an example:
I have a Lenovo power supply:
What will happen if I use it to power the docking station?
Will this result in the docking station negotiating 5V 2A to satisfy the L5 voltage leading to getting just 10W? Instead of the 30W which would be required for L5 plus the docking station?
Or will the docking station negotiate higher voltage and then transform so that it feeds L5 with 5V 3A?
If both are possible, how to understand what is the docking station going to do?
