"slow" and "normal" are all relative terms, and aren't definable.
It's also relative to the size of the battery. A cell phone at 20 watts charging sure aint slow, but a laptop at 20 sure is. But is 20 fast when phones will do 50 or 100 watts?
What I'm referring to is what my device states. Right now, my tablet states that it's slow charging but my other android devices just say charging and my mom's phone states that it's fast charging when she uses the cable that came with her phone.
Sounds like it's the standard 500mA USB charging. This is the slowest and oldest charging that exists. It's telling you this in case you have a charger that supports faster charging but using an older cable, in which case it falls back to 5v / 500mA. You have to have a proper charger and cable to get the higher modes (e.g. USB-C PD).
There's nothing harmful about this and is actually better for battery longevity as many others have stated. The notification is just informative in case you're expecting faster charging. 5v / 500mA takes forever compared to modern charging standards.
