Customers are saying

Customers recognize the MAX 30,000mAh power bank's exceptional battery life, allowing for multiple charges and lasting power throughout the week. Its power and portability are also praised, making it a convenient option for various devices. However, some find the device's size and weight to be substantial, impacting its portability for everyday carry. The power bank's large capacity is a significant benefit for many users, despite its size.

    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

    Works good for charging devices but takes over a day to fully charge itself. I’m not sure if I got a faulty one but it serves its purpose. I do like the 3 outlet options. It is also quite heavy.

    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!

    Bought this as a gift for family and friends. They seem to really like/use it!! I have one for myself and it works great! I like the battery indicator on the power bank itself, the USBC and USBA ports and the little handle which makes it easier to carry with you! Highly recommend

    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.

    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.
