How bad is it for a mobile device to be "slow charging"? (lemmy.ml)

I bought a new tablet but I'm unable to use the charging cable it came with until I can get an adapter because I don't have anything that can except USB type C. I have multiple cables with a USB A connector but the tablet says that it's "slow charging" when I use them. I tried to look this up before posting but for some reason, a lot of websites refer to "normal changing" as slow charging now and I'm unable to find anything relevant to my issue. Would I be fine to use the other cables I have until I can get an adapter?

Edit: I no longer need help with this. I originally made this post because, for several years, I was told and had read that both slow and fast charging damaged batteries significantly more than normal charging. But, as multiple users have stated, it seems like I was being told and reading false information and slow charging is actually better for a battery than normal charging.

When you say "slow charging", are you talking about actual slow charging or normal charging? As I stated in my other comment, I've only ever heard that about normal charging and never about slow charging.

The slower the better for battery health.

Usually slow charging is just the standard USB 2.0 output, which is 5v 0.5A (so 2.5 watts). That was all the USB standard officially supported for a long time, but many devices and chargers actually supported up to 5v 1A (5 watt) or 5v 2A (10 watt) charging. Those would usually be considered normal charging.

Fast charging has a couple different specs and voltages, but can go up much higher. My steam deck supports 45w charging, and some laptops support 65w or higher.
