This is Portable Power bank circuit project to backup energy when need mobile phone that no electrical outlet.This app is basically developed for assist & support to electronics engineering students for their project work.It consist project synopsis of portable power bank circuit for academic purpose.

Portable power bank play an important role in life because if we are in the satellite area there is no outlet to charge mobile phone and mobile is about to die so its difficult to manage without smart phone. If we carry charging backup with portable power bank then it solve problem to charge mobile phone.

Thus requirement of portable power bank going to increase day to day. Learning circuit design of portable power bank is bright for electronics engineering student.
