    I use this allot and it saved my life multiple times when I needed it to charge my phone when it was nearly dead on more than several occasions, as my phone battery doesn't last as long as it use to anymore.

    Use daily to quickly charge my IPhone, while a little bulky when fully charged it delivers days worth of use for me before it’s down to 25% and in need of recharging.

    This product is great, but just be aware of the FAA regulations. This is too big of a battery to take on planes without prior approval from the airline, so you may risk having is confiscated by TSA and they don't give them back. I have a smaller Energizer I use that works just as well and is FAA compliant. It's the 20,000mAh size, that is allowed & they also sell it at Best Buy. The packaging looks similar, so make sure to check which one you are getting.
