Extend your battery life without adding much bulk!

I bought this battery case with a trip to Las Vegas in mind. With 4,000 mAh of battery life, you'll get about 1 1/2 full charges on your iPhone 6S Plus. Now that I have this battery case, I don't have to worry about being away from a wall plug for a long period of time. I was able to stay unplugged while enjoying the Vegas nightlife until the wee hours of the morning and still had battery life left when I got back to my hotel room. This battery case is now one of my "must have" travel accessories. #RankBoosterReview #Sponsored #Niubity
