How fast is "Fast Charging"?

[GalaxyQuester]

Hi all,

I have a S7 and I've been measuring the charge rate with a Keweisi power meter such as pictured here:

The top charge rate seems to be about 1.5A using either Samsung's Adaptive Fast Charging Wall Charger or the RavPower 60W 12A 6-Port USB Charger Desktop Charger

Questions:

1. Is a top rate of about 1.5A what I should expect? Is the Keweisi interfering in any way with the fast charging?

2. The RavPower page suggests that the S7 can be charged at 2.0A. I'm sure this is just a theoretical limit. In practice, what rate should I expect?

Thanks!
