1. What is Power Banks?

Power Bank adopt polymer battery cell or 18650 li-ion cell inside,can ouput to recharge most of mobile device.

Mobile device mean mobile phone,digital camera,Game device,MP3,GPS,Bluetooth headphone etc.

2. Why power bank capacity and price make so big difference?

Generally you get what you pay for, the bigger the capacity the price also is higher.But if some power bank capacity is very big more than 10000mAh, but the price is very cheap, it must be fake capacity.Generally famous brand the price is quite high, capacity and price is proportional.
If the same capacity power bank, the price almost the same, maybe batteries type use different and 18650 battery price is cheaper than polymer battery.

3.How long will power bank stay charged if I don’t use it?

Should last quite a long time. A lithium battery should last a good two or three months but it depends on the design of the power bank and how much drain is on the battery from the internal circuitry. They should certainly last long enough for anyone to use them for charging their phone over a week or more.
