YES! Any advice for a special one? My friend recommand me one 14,000mAh pack: http://www.amazon.com/RAVPower-Lightning-Thunderbolt-Incredible-connectors/dp/B00EHEEFWY/ High capacity and an acceptable price. Still wondering if it may fit my Samsung Galaxy3 well because we own the different phones...

Dear all, my phone started to power down after using almost half a year. And l thought a power bank could be helpful when I was outside. After went through so many types and brands of this kind of product, I still have no idea to pick one. Especially when you almost make a decision, then you found some negative comments. So if you have experience in using this kind of product, please share with me. tks.
