Portable Power Bank for Mobile phone

Judgement Time!!
Hello people, so i need a portable power bank for my phones. Smartphones as we all know have poor battery life and while travelling, i always cant seem to find a charging point to charge my phones. So am looking for a portable charger with capacity of about 7500mah or more. My primary phone being Sony SL, i need a charger which can charge the phone 2-3 times atleast. The budget is about 2000-2500. Also prefer a charger which can charge the phone as fast as possible. Please help.

Anyone??
