ok, one last thing, if i am designing a power bank using 3 cells of li-ion battery, do i connect them directly to the tablet using usb connection or do i need to add protection circuits (under voltage lock out , current limiting... etc) ?
could you recomment any of these cheap chargers?

this also made me wonder, for the tablet or any battery powered device in general, is it the responsibility of the charger to measure both voltage and current or this function is implemented with internal circuitry in the device?
I want to design a circuit to make a power bank for a 5v 4A tablet.
it would be so great if someone guides me to a good tutorial about the theory and the practice.
also, as a citizen of third world country, i wish to find any circuit with popular ICs to make it.
thanks in advance...
