That's 4.25W (5 x 0.85). A USB2 port is rated for 0.5A (2.5W) and a USB3 port for 0.9A (4.5W). So if your computer has USB2 ports, that fits. If it has USB3 ports, it should be as fast as your Kindle charger.
I use whatever I have to hand to charge my Sage, from your run-of-the-mill 5V/1A chargers to my 80W OnePlus charger from my phone (which can do 20W at 5V I think). I must admit I have never paid much attention to charging times, I just let it charge overnight.
