    I bought this to keep my cell phones charged during our Disneyland vacation. Worked perfectly from a backpack attached to a 10 foot lightning cord. Worked flawlessly. Awesome!!!

    I bought 2 of these for a upcoming trip that we are taking and I like that they charge faster than another brand I've used. Does take awhile to fully charge but that's to be expected. So far so good!

    In the week-and-a-half that I've owned this I've charged my phone countless times, iPad, AppleWatch, Nintendo Switch, Switch Controllers, etc. and it's only half-dead. Love this charger.

    Used this battery for a trip to Japan. It was able to charge all sorts of phones, cameras, portable WiFi, and tablets. It would last 2-3 days before needing a recharge. Highly recommended!

    Anker has become a household name and makes a great product. This one has a huge capacity and is the same price as many other brands that have half the capacity or less at the same price point.

    Really useful for long road trips or when camping. We needed it to recharge phones, and GPS devices. Lost count on how many items we recharged over the weekend. Very useful.

    I’ve used this charger several times and it’s still got power left over to charge my phone. I’ve only charged it one time. I’ve used other charges but none have power like this. Get it!
