The syska is already a trusted company. I am having this powerbank in white colour, I bought from flipkart in offers. If I say about its battery life its awesome, I have to charge 4 to 5 hours for doing battery full. It can charge upto 3 mobiles. It haves 2 slot so you can charge 2 mobiles at a time. The design of the powerbank is good and pocketfit but I think it should be little bit flat, if you have bag you can keep it inside and charge your phone. If I say about money spend on this powerbank, I have no issue or complaint regarding this powerbank. I am using since upto last 1 year, I dropped it 3 to 4 times but nothing damaged occured in it. IF YOU PLANNING TO BUY A POWERBANK AT LOW COST THIS IS THE BEST.
