Not sure about duty. It comes in electronic items and is quite heavy. Do share your experience with HBL i.e the dollar rate they used for this transaction.
How much did you get this one for? Original? Share the link please.
I got 10400mAh one original from here(verified on website). Its very good for the price and beats the other power banks in same price/specs. I get 3 charges easily on galaxy s4(2600mAh battery from 20 to 100%). You can check reviews, specs and teardowns online to see how good it is.
Tracking depends on the shipping method. What was it when you ordered?
