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 I originally made this post because, for several years, I was told and had read that both slow and fast charging damaged batteries significantly more than normal charging.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.

The primary difference here is where the power supply duties are performed. With USB PPS it can "outsource" the power supply tasks to the charger. When using "classic" fast charging (e.g. 5v / 2A) the phone has to handle all the voltage conversion internally, which adds heat to the device.

Are you saying that when the charger handles the conversions, it will also produce waste heat in the process? If so, the total amount of energy lost due to conversions should stay the same, but the physical location where the heat is generated is different. That would be pretty nice for the battery longevity.

Correct.

Nice. USB PPS sounds pretty sweet. I better look into that.
