Hai friends, I bought Intex Power Bank 10000 mAh IT-PAB 10K POLY from flipkart on last May. The product is light weight, stylish and charges faster. It gives a better performance so that one can obviously charge any phone twice fully. The product has a built-in Li-Polymer battery which gives good backup and economical. It contains a micro USB cable but not recommend for countinous long time charging.
I am happy with this product and seems to be good.
