Personally, I find the included USB type-c charger a bit chunky. I'd like to buy a more compact, portable charger. I quickly tested my phone's 18W charger and the S540 was charging (though slowly, obviously). The included charger has 60W (20V, 3.25A). However, it appears to me that the majority of compact chargers has 60W (20V, 3A). Given that the 18W charger worked, I suspect a 60W charger will as well. Will constant usage of 60W instead of 65W cause any damage or problems to the Ideapad? Also, is there a way to read out the supported Power Delivery modes?

We do apologize for the late response.
Using a charger with lower voltage will eventually work or will charge your computer's battery though the battery will be under power which causes the battery to easily overheat and makes you encounter an auto shutdown without prior notice while working on your computer. Being said that, it is not advisable to use a charger with lower voltage than what was recommended by the manufacturer.
Hope this help answer your query.
