    Product worked great. Got the initial charge in before a snow storm that left us without power for more than 3 days. This allowed us to charge 4 devices twice fully before going dead. Would absolutely buy this product again.

    Anker has always been a reputable brand and continues to outperform the competition. The charger has saved me multiple times specially the 20k supply helping charge not only my phone but any gear I have on me.

    Works as advertised. Two usb-A plugins plus a usb-c plug-in. Not the fastest but will cover you if needed. Ipad, iPhone, Samsung phone. Don't make me no matter what I got plugged in, it's getting charged.

    This a fantastic charger. I use it for travel. I can keep my phone plugged into it for my entire 6 hour flight and it barely drains to half charged. And my phone and ear pods are fully charged the entire time
