The Aukey PA-T14 charger regulates fast charging and is therefore suitable for the Samsung S7 and S7+. The important thing with fast charging is not to use a fast charger whose power exceeds the maximum value allowed by the tablet or mobile phone. A lower power rating will result in a slightly longer charging time, but without risk.

Works well with my S10 and its accessories. Never tried it with a Tab

I didn't ask myself that question. I use it when I'm travelling and load everything I need.
