Hi,
I recently purcharsed my new Swift 3 laptop (SF313-53-503A) and I'm satisfied with it.
But I wonder if I could charge it via USB-C port. I removed all the stickers on my laptop, but as I remember, that USB-C port is named Thunderbolt 4.
If I can charge via Thunderbolt 4 port, does the charger have to meet a standard? Like 20V-5A or something like that
I own a 65W charger and also purchased a 100W charger, can I charge my laptop with these two?

    On Intel website they say Thunderbolt 4 supports up to 100W charging so I hope I can charge it with my 100W charger.

    The SF313-53 manual (p14) says:

    USB Type-C information
    • USB 3.2 Gen 2 with transfer speeds up to 10 Gbps.
    • Supports DisplayPort™ audio/video output.
    • Compatible with Thunderbolt™ 4.
    • Delivers up to 3 A at 5 V DC for USB charging.
    • DC-in: requires power adapter or power source providing 65 W at 20 V.
    For optimal performance, please use a certified Acer power adapter or USB Power Delivery device.

    So you should be right with the 65W charger you have. Using the 100W charger might be risky though.

    As a follow up, I found a youtube video of a guy testing various chargers on a Swift 5.

    Bottom line was that 65W chargers worked, 90W charger & some low wattage chargers didn't.

    Thank you so muchhhh this video is really helpful. 
    The fact that 90W charger didn’t work really makes me feel disappointed :(
    But that Swift 5 USB-C port is Thunderbolt 3 so I still hope my Thunderbolt 4 port will allow up to 100W charging...

    Since you already have both 65W & 100W chargers, I guess you can just try them. At least the Swift 5 in the youtube video didn't blow up with the 90W charger!!

    My friend borrowed 65W charger and the 100W charger is not yet shipped  :#

    A 100W charger should work fine, as long as it's providing the same 20V. It won't be any faster than the 65W though since the current is determined by the charging circuit rather than the charger. If you tried, for instance, a 45W charger it would either charge slowly or not at all because the charger couldn't keep up with the demand, but a larger charger can handle that demand, so will work fine.

    Do you mean my Thunderbolt port is only capable of 65W?
    And my 65W charger can provide 20V output so I guess it will work.

    Yes, it's not a limitation of the port, it's just what the draw is from the charging circuit. The Thunderbolt port doesn't melt or pop a fuse with a higher wattage charger, because it doesn't try to pull more amperage than it's designed for.
