Charging time extra long on S5 charger

[anon(749368)]

My S6 charges really fast on the fast charger that came with it but at work I have my S5 charger and it takes forever to charge (15% in 2 hours). Is this normal? When I had my S5, it's charger would charge it pretty fast so I'm wondering what's the issue here...

How is the s5 charger fitting in your s6? Mine has I think it's called USB 3 connection and will not fit in my s6.
