    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.

    This is a very nice charging pack. The 30,000 packs can be a bit heavy, but this one isn't too bad. It works nicely in my pocket.

    Very heavy for a portable battery. Comes with charging cable, but you need the adapter. Had to search through several adapter until one worked with this unit.

    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.

    Bought this product for Disneyland; absolutely the best portable charger I've ever used. Incredibly fast charging, only took 30 minutes to get from 20% to 90%; battery of the portable only lost 16% throughout the entire trip (2 1/2 days). Highly recommended.

    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!!!
