Question: how much electricity does it take to charge a mobility scooter?
Answer: So from there it should be a simple matter of multiplying the wattage (expressed in kilowatts) by the hours, and then by the price. For a 7 hour charge, 90 watts for a 4 amp charger (commonly the size for an everyday scooter), we get 7 x 0.09 x 35c = 22.9 cents.
