I am pretty sure each phone only has one charger. All electronic devices have power cords/charging cords, most which are not compatible. I have more non-cell phone power cables than I do cell phone power cables.
Easy solution - make sure everything comes with a charger. You don't have to replace anything, it's free! New phones are going to come with chargers anyway - don't you se.....
To both of your all post you all failed address one huge part agrument.
If you only have one charger it is fine but a lot of people buy a car charger and some even buy a 2nd cell charger. Now if you and when you changed phones that car charger, and spare charger are now complete garbage and you have to go buy new ones.
I know I like having 2 chargers and a car one. It is one charger for home, 1 for the car and then one that lives in my bag for when I travel. It also means if I forget my charger there I have a spare.
I will say it was really nice when I would go to my parents and my mom used the same phone charger I did because I would just leave my charger at home and use hers. It prevents me from having to worry about not having one.
