Thanks man, I think I'm going to give the charger to my friend. I just need something more sturdy like Efest SODA. How about the i2/i4? I heard that those charger take a long time to charge 2x18650. Also, what about the D2 that you owned? How much time does it take to charge up 2x18650?
My D2 took about 4-5 hours to charge 2 batteries, each bay charges at 500ma. However after like 2-3 months it decided it was only going to charge my batteries to 4.07 volts everytime (verified with my multimeter, even though the D2 said they were full). Stopped using it and went back to my xtar MC2 which charges them perfectly. Get an Xtar, its a little more expensive but you dont hear anywhere near as many complaints about Xtars as you do Nitecores..
