Dysfunctional charger in laptop

The charger I'm using right now is my second one after the first got burnt but what's in common is that they at first remained fixed on the charging port while after some time they start getting loose and you can actually move them up and down the port while they're charged. What concerns me is that while there's a red light below the charging port that shows the lap top is charging, there's no charging icon on the task bar. Is this somehow a sign that the adapter might get burned out? It should be noted that the battery percentage is increasing with time but the absence of an icon and the loo
