Hi, I often go hiking and climbing with my friends. But there is a problem annoys me for a long time. Sometimes I use my phone take many pictures on the way, at the same time, the power drops quickly, and many times it died on the halfway.Some of my friends suggest me to buy an external battery charger. At first I want to buy Anker E4, 13000mah, but one of my friends told me it cannot charge Sumsung pad. So I changed my mind, after a lot of searching, I found this one eventually: RAV Power 14000 External Battery Pack. Is there anyone has heard about this brand? How about it, have you ever used it? Which brand are you using when go hunting or traveling? Really hoping someone can give me some advice. Many thanks!
