Oh no! your battery is at 10% and it wont be until another few hours till you can get to a wall outlet! Good thing you brought your portable charger! This is a simple casing for holding the components to charge your device on the go! You would need to break apart a cheap usb car adapter charger and a 9V battery and fit them inside this case and you can charge your phone whenever you need! Just change the 9V battery when it dies.
