Portable charger 1000 mAh

I just bought a cheap power bank at a local store and the instructions didn't say about how long you should charge it or how Long it last the details are 1000mah capacity// Input-5V/500ma Output is 5v/700Ma. So how long should I charge it and much percentage will it bring my iPhone 4S on standby.

It will charge your iPhone 75% because iPhones 4s have a 1432 mAh battery. It should stop charging on its own unless it is one of those really cheap ones. If it is the really cheap one than charge it for 1 hour. Newer models have auto stop charging.
