I own several Power Banks, however I have to say that this one is my new favorite!!!  I always grab this one before I will grab anything else.   Most of the power banks out there, will have lights that will tell you how much power you have left, but to be honest, you never really know how long it will last.   The Lightening Power Bank is a step above the rest, as it gives you a digital readout with the percentage of how much is left on the charge. What a FANTASTIC feature!! I use a Portable Charger all the time, but you never know how much charge it has and if it will go dead on you as you are out running your errands. This Lightning Power Bank, I can pick it up and know ok, I have 62% charge left on it, and I am good to go. read more
