The Anker PowerCore III 10K portable charger has fast USB-C out charging (18 watts) in addition to a USB-A port and as many as 10-watt wireless charging. It is not magnetic, so your phone is not going to stay with it but it will eventually wirelessly charge any Qi-enabled devices. https://allhealthmarket.com/product/computers/power-bank/battery-capacity/15001-20000mah/ugreen-20000mah-power-bank-with-charging-cable-portable-external-battery-powerbank-for-android-and-ios-mobile-phones-power-bank/
