Dual charging on UM425
hi, I have a zenbook UM425 and it is charged via USB C
on its left side there are two USB C port, and either one can be used to charge the unit
one day I left my charger at home and in need of charging, so I used my phone charger. its rated output is 15 watt per slot (has 2 slots). the zenbook battery managed to stay longer even though battery percentage eventually dropped slowly.
my question is, is it possible to use both USB C to charge my zenbook? since either one can be used for charging and my phone charger has exactly two slots.
yes, I realize it will never replace the original charger since it is rated at 100 watt. but is it possible to charge both USB C at the same time?
