I love portable chargers. I use them a bunch when I'm traveling and out on an all-day exploration where no electricity is available.
Unfortunately, this one did not work for me. It did take a full charge upon the initial set-up but when I plugged my USB lightning cable to charge my iphone it would not recognize my device. I tried it several times and nothing. Other portable chargers I had on hand worked fine. Maybe I just got a dud. I took it back.
I gave it 2 stars for compact fit, amount of charges it was supposed to give and price. It was on sale. Had it worked, it would get 5 stars. I would not totally count this one out because it may have just been a rare dud but keep your receipt in the event you have an issue; that's with anything you purchase.
