I own a 2017 MBP 13" (A1708) with the battery replaced about 6 weeks ago. Everything went nicely until this week, when it started charging inconsistently and coconutBattery shows 5-10W of charging. I plug the charger and it says "battery doesn't charge". Sometimes reconnecting the charger helps, sometimes not; the same is true about waiting some time. I've reset SMC couple time but it usually doesn't help. I’ve attached of screenshot showing coconutBattery output.
Also I’ve ordered a new charger and cable.

This one's probably going to come down to trial and error.
Potentially coconutBattery is providing incorrect information, so pay attention to the actual system behavior -- is it draining too quickly? Taking too long to charge? etc.
