I believe as long as it fits, it should be good. Most chargers are made to charge many types of lithium ion and rechargeable ni mh batteries. I use several of my chargers for both 14500, 18650, and rechargeable AA
So long as it is the newer Xtar VC2. The older trustfire chargers I'm not sure would physically fit it? Though I cant say that I've tried since I don't have any 18650s
