Hi
USB Power Delivery charges can deliver 100W of power (20V/5A). There are existing adapters that take the USB PD input and deliver 20V DC power on the other side for charging legacy laptops with USB-C chargers, eg. here.
So my question is, could take the output of such an adapter and feed it to Orion-Tr Smart 24/12-20 for charging my battery? The Orion accept voltage range of 16-35V so 20V should be good enough. Or am I missing something? I am not looking into a bullet proof solution (like a dedicated 220V charger) but rather for backup solution to be used occasionally.
