hiii
please anyone help me by explaining the functioning of power bank...i have a doubt , how 2800mAh power bank is used for charging 2200MAh battery by completely draining out itself... i stuck with the idea that current flow is from higher potential to lower until both are at equal potential...if it so, then how a power bank is working by completely draining out itself....
help me please
Thanks in advance
