    I used this powerbank to keep my gopro running non stop. I used it for 6hrs straight recording on my kayak and it still kept a full charge at the end of the day.

    Use it every weekend. Gives me about 7 to 8 charges on my Samsung S9. Used it on my trip to the Philippines, didn't even use half of it. Amazing product!

    Works like a charm! As other reviews point out, initial charge takes a long time (overnight). Charged two Android phones quickly with plenty of power to spare.

    Holds a lot of juice to power phones or what not. I used it to run one of those cube shaped usb personal AC machines while camping and it ran it for a long time

    It is a great charger. I can just put it in my jean pocket to charge my phone while listening to the music using my iPhone. Very handy product to use.

    This is a great addition to your pack when in the field. I found I could easily get three charges while on the stream or trail. Don’t leave home without one!
