Is 61w adaptor powerful enough for 2019 13 inch Macbook Pro?

One would think it should be powerful enough for 13 inch MacBook Pro since Apple supplies it in the box, but while observing "Charge Remaining (mAh)" in Power section of System Information, I notice this figure would steadily and slowly drop under light to no load while AC is plugged in (System Information shows Fully Charged: Yes and Charging: No).

This figure does remain at a constant value if I use a 87W adaptor. I am not sure why this is the case. It makes me feel somehow the 61W adaptor is not powerful for this 13 inch MacBook Pro...

MacBook Pro 13”, macOS 10.15

From: Find the right power adapter and cable for your Mac notebook - Apple Support

"You can use a compatible higher wattage power adapter without issue, but it won't make your computer charge faster or operate differently. If you use a power adapter that is lower in wattage than the adapter that came with your Mac, it won't provide enough power to your computer."

Please be sure to read the entire Apple Support document BobTheFisherman provided. Both the power adapter and cable are important.

Yup, I am wondering whether the adaptor that came with my Mac provides enough power to my computer. From my observation, I have a suspicion that 61W is not powerful enough for a 13 inch MacBook Pro, even if it did come with my Mac.

Just wondering if anyone has experience to share to prove or disprove the suspicion that the 61W that came with the 13 inch MacBook Pro isn't powerful enough for the Mac.

Thanks

There are millions of Mac users. If there was a systemic issue with insufficient power we likely would have heard about it and these communities would be bogged down with posts about the issue.
