A very easy to use charger that works quite well. I use this on all my Coolooks as well as nite core and red efest IMR type batteries. This charger has worked with a few other off brand IMRs Inhave used in the past as well. Seems to be compatible with most, if not all, IMRs. If you need a charger for a different size IMR, check out the Nitecore Intelligent charger that Luke sells. I have that one as well and it works great for batteries that are not AA size.
