So, yes, you should be able to use the fast charger with other devices without damage. It shouldn't make any difference to charging time unless the device was capable of higher charging rates than the original charger could provide. I don't know if the sage was designed for fast charging. But, theoretically, you could plug it into that fast charger and see.

Now, of course you've seen all my weasel-words in the above. IANAEE (I am not an electrical engineer (or anything similar)). So, I can't guarantee any of the above. But, that's what I keep reading. I guess, to be safe, you could chat with Kobo.
One friend of mine destroyed his new Onyx(?) by connecting it to a Huawei(?)cellphone quick charger. Evidently, the charger decided the Onyx could quick charge at 20V. The charger was not standards compliant.

The Sage will not charge faster by using a fast charger in my limited testing.
