Minix 2500 mAh Power Bank  (Blue, Lithium Polymer, for Mobile)

Nice product. Excellent charging. I charge my note 2 with it. It is able to push in at least 75 % charging to it (Because this is just 2500 MAh and Note 2 battery is 3100 MAh). The aesthetics of the product are also fabulous. There is no need to attach any external cable for charging; the cyan blue colored plug is infact the charging pin. Wire is not long enough though. I would highly recommend this product.

I use this to charge my samsung galaxy S3 and it charges the phone from 0 to 100 percent in two hours. It has both a stylish and a modern look and fits easily into the pocket along with the phone so that you phone will be charging while it is in your pocket! But i feel that they could still improve the shape and design to fit perfectly into the pocket along with the phone.

Definitely a go to product. Has a sweet build and form factor, is insanely good while holding it with your smartphone too in your hand. Delivers close to 2100 mah I would say. Since the cable is attached its the most comfortable and compact power Bank. I used it with my Xperia ZR and it would give me good charging rates plus 85% battery when chargered from nil. I have been using it for a year now. And I would certainly recommend this product.
