Making some futurism:
Paying with a Power Bank at the supermarket
Maybe one day a Power Bank can charge 45kWh, so:
(Power).(euros/kwh) = (45kWh).(0,11€/kWh) = 4,95€ = 5,00€ aprox. .
Step 1: Plugging the Power Bank to the wall to charge it
Step 2: Going to the supermarket with the Power Bank
Step 3: Paying with the Power Bank at the supermarket
Thanks for your visit, Cheers!
