Here's some fun math.
I determined it takes about 80 mAh of power per bowl. Based on an 800 mAh battery giving an average of 10 sessions per charge and 4 heat ups per bowl. Therefore, it takes around 20 mAh per hit. Now the charger charges at 1000 mAh or 16.7 mAh per minute. So, this means it takes 1.2 minutes to recover after a heat cycle or roughly 5 minutes to achieve enough for a session." — Summer
