Features a good power bank must have :-

1. Body material should be of type which will minimise the energy loss
2. Should protect the device (i.e. phone) from overcharging
3. Should have intelligent current management system which will recognise state of battery and maintain voltage and ampere to avoid overheating of phone battery
4. Should provide maximum approximate capacity written on its cover
5. Should not get heated up while charging or discharging
6. Should avoid short circuit when over current flows through it
7. Should be portable
8. Should have one fast charging port for fast charging mobiles and one normal charging port for charging small devices (ipad, BT earphone etc.)
