Funny that you mentioned the nitecore charger as it was my second choice, I had read quite a few positive reviews on Flashlight forums and for $20 i still might grab one as a back up!!
yeah i'm just a recent newbie here but have been in the flashlight forums for years..CPF and now mainly BLF as the guys are a lot nicer and it's run more openly..
the nitecore is my go to charger..I got it and 3 panasonic 3100's when I grabbed my neutral thrunite tn30 off hkequipment..they had a wicked package deal..it's a great charger that terminates religiously at 4.18v..my trustfire 4 bank terminates from 4.2-4.24v..both are decent but for aroudn the same price the nitecore is in another league..
