But, one thing to note. USB-C is usually going to be more powerful and this charge faster.
The charging speed is also limited by the device. I don't know of any kobo that actually takes more than 7.5W (1.5A, though they recommend a 5V 2A charger = 10W). A 20W or 100W USB charger will only charge at 7.5W (5V @ 1.5A) if that's the maximum the device takes.

You are an outlier. Also there are plenty of USB-C chargers that are not 100W or even not more than 15W.

While 7.5W and 10W USB-A chargers are the most common there are several protocols for 3A at 5V, and also for 9, 12V and 20V charging on a USB-A 2.0 cable up to 30W.
