Hello users,
So u all think u can charge ur 4000mah battery containing mobile 2and half times with 10000mah power bank but it is not true do u know the reality ok let me tell
Companies mention 10000mah for marketing but final battery we get is aroung 6500mah because there r chips inside powerbanks they generate some heat and for generating heat some power is required and when we dont use power bank some power will get lost because of open circuit.
All the companies make users fools . they dont reveal these they use this for marketing. if u dont belive me google it.
Share it to your friends and family so that they can know the sad reality behind powerbanks.
