Nintendo switch charging

I only getting .35A when charging is it ok or do i need to replace anything ?

If I plug my 5 Volt powerbank to the Switch powered off, the charging starts with .45A and after powered itself on it jumps up to aprox 1.20A. In the end, when the battery is full, the amperage drops to .35A.

If You haven t got any other issues with Your Switch, I would guess it s ok.
