so there's a couple of legit companies that sells them , and thats great , because they're all about quality and style , and i like it .
but the con is that they're 10.000 \ 15.000 mah max , and if 9000 mah priced 70$ i dont know how much will they ask for 15000 .
and theres option 2 . chinese power banks from ebay . 15000-50000 mah . ( of course 50,000 mah in chinese means 25000 approx )
but it is still bigger than the legit ones and lot more cheaper . (30$)
so do you guys use those? any suggestions ?
