My present charger deliver 0.750 Amps and it takes 4 hours to charge a mobile phone.
I plan to buy a tablet charger which is fullly compatible with my mobile phone, which delivers 2 Amp.
I plan to do this expecting that the charging time will be 2.66 faster (2 / 0.75) times faster. So, I expect the mobile to be charged in 2 hour 40 mins.
Known issue :
Most electronic devices has a circuit which limits the maximum current that is allowed into the battery. (I am not aware if my phone has this)
