well its not the end of the world. id would avoid using 3rd party chargers.. cause it may not be good quality or same voltage. hence damaging the battery.
but if you use the Samsung once , you should be fine.
you can look at my thread ( in my signature ) i have a section on chagrin + links to MS official sites )
I recently dug up an old Motorola Q I was planning on giving to a relative, and when I tried to charge it with a Samsung microUSB charger I had laying around it didn't work. I had to look for the original that came with the Q. Other than that, I haven't had any problems mixing and matching chargers and devices.
