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.

    This works great, it came pre-charged which was good because it’s only downfall is it takes about 12-16 hours to fully charge from a 20amp iPhone charger. Once charged it gave me 5 days of charging up my phone excellent for emergency backup during the hurricane we just had!!!

    I bought two of these to heat two vests to go to Blue Ridge GA for Birthday trip (it was cold). The battery held on a pretty good charge. It also helped keep our phones charged.

    Its very heavy and cheap plastic. Not a fan of the button being on the side. The usb-c port felt like it had been used. Impression that it is refurbished open box, even though packaging was sealed and sold as new. Dont expect the type C port to last long with how loose it is. For this large size there is enough space to have built-in cable but they cheaped out.

    I have wanted to get a power pack for a very long time and kept putting it off. I just love it. It is so convenient and it holds a lot of charge. I can charge several things at the same time and it has several different size ports too. I highly recommend it!
