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.

    I brought this battery bank because my previous one no longer works. I’m glad I did, because a day later, my neighborhood had a power outage that lasted all day. This battery bank charges my phone very quickly within 30 minutes and the bank still have enough charge to charge 2 more phones.

    Wonderful battery - too slow to recharge

    A fine battery pack. A little heavy, but considering its capacity, no surprise. Multiple outputs is what is to be exoected. I'd like to be able to charge it either on the C port or the standard USB port, but the instructions don't day anything about that. My only real complaint is the low charging rate - 2 amps. For this 30 amp-hour battery, this mean an over night recharge 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.

    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.

    This has been so helpful to have! I’ve been in several situations recently where the car charger didn’t work & my phone was almost dead. Charged things right up. Also use it while traveling so I’m not plugged into an unknown outlet.
