Can you use old chargers with the Galaxy S6?

[AC Question]

I have a bunch of old chargers from Naztech, output is 5.0V/2.1A. Can I use these with the S6, or do I have to replace all of them?

If they have microUSB connectors, you can use them. You may only get a USB charge rate (about 450mA) unless you short the data pins (pins 2 and 3) together at the charger - that's Samsung's "this is a wall-powered charger" signal.
