    When chaos descends and your devices fade to black, this beast awakens—20,000 milliamps of raw, unrelenting energy surging through its veins. The built-in USB-C cable lashes out like a lightning whip, striking down battery anxiety in a single glorious burst of wattage. It doesn’t “charge.” It revives. It resurrects. It defies all odds.

    I just bought this for Pokemon Go Fest in New Jersey and it recharged my phone (Samsung S23+) and a newer iPhone from about 20% to 100% in a few hours while we played at the same time.

    This is the second time I have purchased this battery in a month, not because anything was wrong with the first, but because it is so powerful and convenient with the buikt in USB c cord.

    This thing is awesome, you dont have to carry another cable with you as it has an attached cable. It charges your phone quickly and when it is dead, it also recharges itself fast too

    This is a great product for the price. During an all day concert we were able to fully charge 2 iPhones and a Samsung S24. Each only took about 25 minutes to charge. I love this power bank!

    I can charge my phone to a full charge about 3-5 times before this goes dead. Built in cable is also great cause you dont have to worry about finding or carrying a cable, and possibly damaging the cable cause its also balled up somewhere.

    Awesome power at a compact size. Perfect for a laptop bag, backpack or purse. (Definitely a bit to big for a pocket… unless you are wearing 90’s era cargo pants)

    I have used this for multiple devices, ipads, iphones, GoPro. Used outside for baseball streaming, it does “overheat” but shuts off with no damage. When cooled it works again immediately. Charges multiple devices no problems.
