    It's too bad it uses usb-c for charging only while using usb-a for plugging in your devices. It would have been nice if the port we use to charge the battery, could also be used to charge your phone. If Samsung and Pixel can figure out reverse charging, why can't Anker? Build is solid. Not worried about tossing it in my bag or my back pocket. I got it on sale, but this battery is not worth the full MSRP. Wait for a sale.

    We purchased on our way to Paris so that we had a way to charge our devices while out on tours. It worked fine.
