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.

    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.

    I use this allot and it saved my life multiple times when I needed it to charge my phone when it was nearly dead on more than several occasions, as my phone battery doesn't last as long as it use to anymore.

    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

    Charger works well to connect with various devices that need the standard 5 volt connection (non PD). The price paid was appropriate for this older standard of USB charging.
