Customers are saying

Customers express satisfaction with the MAX 30,000mAh power bank's long battery life, convenient LCD screen, and ease of use. Many appreciate its multiple ports and consider it a good value for the price. However, some customers find the device to be bulky and heavy. A few users also noted that the power bank can get warm during use.

    The device is great but its a bit oldschoop for it to not let me charge my phone though the inclided USB c device, it seems it was only put there to charge the bank. Its also really weird when you connect your phone it soemtimes doesnt detect your phone conected to it so you need to press the button on the side.

    I have only tried to use this 3x in the past 6 months and twice it failed on me. The ports don't work with consistency and Best Buy won't take it back. Would not recommend.

    Returned. Maybe mine was defective or the box had a misprint. The USB-C port would not charge my iPhone 13. Would start and then shut off after a few seconds. Took too long to charge.

    The product was defective upon purchase and did not even work. Although the product is typically fantastic, Best Buy needs to work on its Open Box Quality procedures.
