I’m addicted to my iPhone, and my Ipad, and my wifi hot spot, especially in combination. unfortunately, their batteries just aren’t up to the demands I place on them most days. The USB Battery Pack from Anker gives me the ability to charge my iphone and wifi hot spot several times throughout the day, and even top off my ipad on particularly heavy usage days. My coworkers know I carry this, and you can usually see charging cords running to my bag to charge my coworkers devices as well! In a small package, there’s a huge amount of stored power. I think anyone who doesn’t like hunting for power outlets, or wont have easy access on the go needs one of these in their bag. Quality product, works as directed. Very handy! (posted by W. A.
