So the charger I am currently using now is from Efest. I got the charger from the Phillipines from which I think is a pretty legit vape shop (in the mall). However, I am a bit skeptical because the instructions that came with the battery seemed to be worded in pretty bad English. No Offense, it sounded like a Chinese man who recently learned English produced the writing. The charger seems to be working fine, but I don't have anything to compare it to. The labels on the instruction manual and the box were the Efest logos, but you know how good some clones and ripoffs could be. I would appreciate if anyone could suggest a great battery charger, preferably with a link. Or should I just keep the charger that I am currently using. There really isn't a problem, except I am just wondering if a better battery charger really makes a difference. Thanks
