Maybe that's why they include the 18350 in the description, and yes it charges just about everything. It was also listed on every other site that sells that charger - I just thought it was funny that the spacers cause that size battery to sit where where they can easily pop out all the time, and noticed it wasn't advertised on the box. Probably not related, or maybe it is? Could be why they make the xtar MP2, but I'm sure I will need the 18650 for something soon enough so I got this one.
Actually they probably didn't plan on anyone charging anything with two spacers, which is why the 18350 sits in the middle of nowhere. But if it gets the job done..... The thing I really like about this charger is the safety of it. People don't realize how dangerous some of these batteries can be.
