    I got this for her as she is forever forgetting to charge her phone. Now when her phone dies she just attaches it and it now allows her to continue using her phone and charges it without being tied to a charing cable.

    Powerbank on the go while traveling is also a necessity. Most airports may not have outlets nearby so great way to stary charged on the go especially if your Iphone has the magsafe on the back of it.
