    If I ever open it and use it? I will before this Friday, I have a two stop flight to the midwest and as much as I'm on my phone, it'll definitely come in hand, especially with these airports that I seem to never find an outlet, and if you do someones using it. Better review coming following week. Was led to buy this with a reliable sales associate that's sold me a ton of stuff, and hasn't disappointed me yet!

    An essential 21st century survival tool

    Life in California, with its aging infrastructure, is either on fire or in the dark. This little charger is an essential 21st century survival tool. I was glad to have it when, just a few days after it arrived, our "power company" once more plunged our county into darkness. But this time, I was prepared with a little extra power in my Go Bag! Stay connected. Stave off the dark. That's my two-cents.

    I’m in the military and we go out to the field for days at times. I specifically bought this to be able to have something to charge my phone when needed. I’ve charged my phone (iPhone 11 pro max) several times and headphones and it still has plenty left to give. Love how sturdy this is, I can put it in my bag and not have to worry about it being scratched or hit. Great product!!!
