But, its portability and MagSafe capability are what have us relying on it for our each day mid-afternoon juice up. https://allhealthmarket.com/product/computers/power-bank/battery-capacity/15001-20000mah/scud-20000mah-power-bank-dual-usb-portable-external-battery-charger-pover-bank-mobile-fast-charger-powerbank-m201/
