Thanks for the coupon! I think I'll get one just to replace my old 5200mAh portable phone charger. I've always wanted one where I could use my own 18650 cells.
I had to go with amazon for the free shipping and discount. Charged up two 18650GA cells; it charged the lower voltage first, as designed. Ended at 4.21v which is fine by me.
Free shipping ! Let us know how you like it after you put it through it's paces a few times. I may end up getting one at some point. What I like most of all with this charger/powerbank is using your own cells, as opposed to a sealed unit and then tossing it out once the built in cells are kaputt.
