    It works great especially if we have a power outage which Texas does get those when we have storms just make sure you have a fast charger attached to it

    Very nifty product keeps the phones and tablets charged, may take a bit to charge the power bank but 3-4 days of use before you do.

    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!
