I spoke with DJI themselves and a DJI repair/stocker here and both have said that you shouldn't be charging more than 15Watts - but they also don't provide the appropriate charger for that. Unless you read through the long manual that says charge at a max of 15Watts you wouldn't know, and try to charge it direct to laptops such as I did where you're potentially charging at 96Watts!! Or 20Watts for an iPad wall USB C charger. I don't understand why DJI have not provided a small 5V/15Watt wall charger USB A-C so that people are charging correctly. I got a wall charger with my Mini 2 Fly more kit and all was good. I shouldn't have to purchase additional items to just safely charge my RC. Really not good. It still seems like something's not right. Because DJI themselves couldn't even tell me if it's normal.
You can charge from a 1000w charger and it will only draw the battery's maximum wattage of 36w in this case, thats assuming that the 1000w charger can provide 12v switching. if its just a 24v charger then you will have issues. So you're either being fed the incorrect information or the language barrier is making it sound that way.
You should be able to use a laptops port just fine, but make sure it can provide 5v/3a, 9v/3a, or better 12v/3a, as long as its chucking out 12v the ampage isn't really a problem as the battery will only draw its maximum and ignore any higher.
Example, for my Mini 2 i am using a 65w 3 port (2x USB-C 1x USB-A) the 1st USB-C port is able to chuck out 65w, the max wattage for my battery is 30w or 36w, cant remember now, but i can stick the drone (and single battery) on the 1st port of 65w and it will only draw the maximum of 30w or 36w which ever it is, i think its 12v/3a so 36w, most certainly it will not draw the full 65w, its called an intelligent flight battery for a reason, it has decent protections built in, I refer you to page 30 of your manual
Overcurrent Protection: The battery stops charging if an excess current i detected
