The Fastest Way to Charge a Segway Ninebot E-Scooter

I have discovered the fastest way to charge a Segway Ninebot Escooter E45. Through regenerative breaking, this scooter can charge at 500 watts! Over ten times faster than the wall charger that comes with it.

I noticed that when I was coming to a stop from a full speed, just for a moment, it was charging at over 400 watts!
