I bought a power bank of 20000 mah. How much is it converted in Wh watts hour? I can't exceed 100 wh on my plane
20000mAh 20000/1000 20Ah. If the the power bank voltage is 12V. then 20Ah x 12V 240Wh. if your Power bank voltage is 6V, then, 20Ah x 6V 120Wh. if your Power bank voltage is something else
