Scenario - use a 5 volt supply to charge and a phone with 2G basic features and simultaneously charge Android tablet from the same 5 volt supply erroneous interchanging the chargers. What is the impact of this on the the appropriate devices ?
Solution - the supply to both the chargers is 5 volts, the current drawn by the the 2G phone charger is 550 mA and the current drawn by the tablet is 1550 mA. using the tablet charger for the mobile causes the mobile to draw the right current without any damage to the phone because 1550 mA is greater than 550 mA. the opposite scenario creates a situation where 550 mA is drawn from 1550 mA supply which does not harm the current device, that is the tablet, but charges the tablet slowly because the phone charger cannot provide more than 550 mA maximum supply.
Conclusion - USB is a universal standard for Android devices. using the same supply voltage with different current drawn in different cases can result in using the same charger across multiple devices but the set device may take longer to charge if requires larger current then the charger can provide 😎
Postscript - Android devices provide an environment which we can use effectively with USB chargers. 😊
