    I boguth this bank based off of it already being charged and ready to go. The car I rented had a USB port that died. I couldn’t risk my phone dying as i traveled three hours to a town I’ve never been to. This one was the only one with this big of a battery AND charged. I opened it and it was at 80% and enough for my trip. While it doesnt charge quickly back to 100 after using it to 69%, its expected and shows its going to last several charges. A full day out on the town doesnt scare me as long as I have this bank. Well priced too!

    Overall when I bought this item, it was for the soul purpose to charge my phone on the go. It’s not really heavy (about 3-5 pounds); nothing too crazy and usually when I’m walking and need to charge my phone I usually put it in my back pants pocket. The battery life on it can sure last a good while (max for me was about 8 days before needing serious charge including serious usage). My only issue with it was when I tried to extend the strap so I can put it on my hand, the strap broke :(
