Snapdeal does not sell fake products. Their products are genuine. I bought a Syska brand power bank from Snapdeal for below INR1000. The product is sleek and sturdy. The power bank is for ******* mah, and with one full charge, it recharges my mobile multiple times. The product was exactly the same as shown on the Snapdeal website, and the packaging too was good. The product came with a six month warranty.
It's been quite a few months that I've been using this power bank and I'm fully satisfied with my purchase.
Go ahead, search for Syska Power bank on the Snapdeal website and experience the life saver power bank!
