Earlier quoted context omitted.
"37 Watts lithium ion battery" is meaningless as a capacity. As is "10,000 milliamps per hour". You likely have a 10 amp hour, 3.7 volt battery yielding a capacity of 37 watt hours. This is about the same capacity as an ordinary smart-phone (perhaps a bit larger, I think an iphone is 5 or 10ish ).
10,000 mah is the same as 10 amp hour. And that is 6 times what an iPhone has actually
