    I got this as an open-box product. It fulfilled all expectations, and washed away any concerns. It has more than enough juice to charge your phone more than 4 times.

    It takes a while to recharge the device but once it is full I can charge my phone multiple times. I like the indicator lights that tell you how much power is left!

    This portable charger has a good design and feels like it is good quality. Had no issue charging it up from my computer and it charges without issue. Haven’t used the fast charging port yet but other than being a bit long (makes it awkward at times to store/hold it) found no issue with this product. The carrying case is pretty nice too.

    Anker makes the best batteries around. I'd trust this over a phony non-branded battery pack that would blow up in my face (and lie about the power ratings). High Five Anker!

    Anker power core provides enough juice to charge both my iPhone and iPad to keep me going. Little did I know how quickly it would be needed with Hurricane Michael hitting!

    20,000 mAH is just insane. Many charges. Although big, I recommend to anyone travelling, or just needing a portable battery wherever they go. I use it everywhere.

    It charges several devices before needing to be recharged. It is a little bulky but i wanted something that I could use several times rather than something small. It works great

    I was surprised at how much it held. I was able to charge more than a few times when needed without losing its charge. It was a lifesaver on our trip to Australia.
