    Use daily to quickly charge my IPhone, while a little bulky when fully charged it delivers days worth of use for me before it’s down to 25% and in need of recharging.

    This product is great, but just be aware of the FAA regulations. This is too big of a battery to take on planes without prior approval from the airline, so you may risk having is confiscated by TSA and they don't give them back. I have a smaller Energizer I use that works just as well and is FAA compliant. It's the 20,000mAh size, that is allowed & they also sell it at Best Buy. The packaging looks similar, so make sure to check which one you are getting.

    Well I bought this Powerbank I thought it would be powerful enough for my ROG Ally it wasn't but it was powerful for my sansa mp3 players, phones and my Samsung Galaxy products. On the bright side it was a bargain comparing to spending 60 dollars more or a little less on a powerbank it was a bargain.

      Hi Kamikazebob,
      Thanks for your thoughtful review! We're glad to hear the power bank works well with your phones and Samsung devices. While the MAX 30,000mAh model offers extended battery life, it delivers up to 15W output—great for most smartphones and accessories, but not quite enough for high-demand devices like the ROG Ally, which typically requires higher wattage and PD support.
      Still, it sounds like you found great value in the purchase, and we appreciate you sharing that perspective!

    great power bank, it is pretty heavy. I love that it has various outlet sizes, this provides more access to using different devices while charging at the same time
