Hi Tech 5200 mAh Power Bank  (White, Lithium-ion, for Mobile)

Its a good product and worth buying at this price.....It can charge 2 phones of 1500mah.....Actually all power bank gives 70% of power on whatever mentioned on the pack.....So if it is mentioned 5200mah it means it will give about 3000mah which I feel is good or enough to charge a smartphone becoz smartphones generally hav 1700mah battery.....Thus this means this power bank can charge the approximately 2 times....It charges my phone quickly in about 40mins.....It take time to charge itself ab...

this power bank works good. good packing and fast deliovery. bt when i recived the product and cheking it its socket comes out. looks like a very cheap product. i manage this problm with febi kwik. overall acceptable.

I purchased it in march month 2015.
whenever I charge it, it get heat and when I connect it with phone, charger is also get hot. It seem like it going to blast.
But after all of these portable charger is good because of fast charging of phone.
