    I have been using the 25w Note10+ charger to charge my Tab S4. Should I not be doing this? It seems to be working fine. I only do it because it's easy and saves on clutter. That being said I will be receiving the 45w charger soon, wonder if that one will work too? I know it won't charge it any faster, but I don't want to harm it either. Any thoughts?

    Any charger is fine. The device and the charger negotiate for the highest common charge rate they have and use it. (If you have an old Android device that doesn't have fast charging, it doesn't negotiate, so it gets a normal charge by default.) If they come out with 100 Watt chargers, you can still use them on phones that charge at 10 Watts.

    (Your home is a 200 Amp, 20,000 Watt, "source", but a 100 Watt light bulb still runs at 100 Watts. The device always determines the current drawn.)

    Cool, thanks for the information.
