    20,000 mAh lasts for several charges. Fast charging is convinent for when my phone has a low charge. Rather heavy, but good price for the power capacity.

    Picked this up to use on my Nintendo Switch for travel. Provided plenty of backup power, and was even able to charge the Switch while in use.

    I bought this for my vacation and I can tell you it does not disappoint. I have been back from my vacation about two weeks and I still use it from time-to-time. It does exactly what it says it will do which is charge your phone multiple times. I must ad too that the Anker brand is really high quality. Their speakers are awesome too! if you need a portable charge choose the Anker PowerCore. There are several other models by Anker PowerCore which I am confident are equally as dependable. Keep up the good work Anker!

    This little gadget is definitely a great buy for under $50. I went on a trip for a couple weeks and definitely came in handy for when I didn't have an outlet available. Not sure how many charges I can get out of a full pack but I would need to charge the pack twice in order to not have to reach for an outlet for my phone for about one week. I love not having to constrict myself to the corner of the bed when I need a charge and want to use my phone at the same time. It is a little heavy but other than that, it does the job.

    Bought it for conventions and when I’m not by an outlet. It’s a little on the heavy side but it lasted for days on a single charge.

    It works just as advertised but make sure its worth it to you to have that much charge on your person. Its quite heavy and will add significant weight to whatever bag you've got on you. Something to keep in mind if you only need an emergency phone charge or two.

    I went threw 3 different chargers before purchasing this one that was cheaper then the rest, the main reason returning the other ones is some what false advertising being that they dont charge phones or get charged as fast as advised and this one charges decently fast and the only problem I have with this is it takes a long time to charge up and the last light doesn't ever stop blinking when charging it.

    I bought two of these to use as back ups for a long flight to Asia for fears that the foreign airports and or planes might not be compatible with my plug in chargers for my devices. Then I read that there are new restrictions for these portable chargers on planes. I took a chance and was very happy to know that this size is the largest size legally permittened for travel. Mine worker excellent when I used it.

    When my boyfriend first mentioned this to me I balked at the price. However, we went on vacation for 8 days and only had to charge it once. It fast charged my Samsung Galaxy S8 and lightning charged his iPhone XS Max and it still had 2 bars left. Definitely worth it
