Question: how many watts does an electric lawn mower use?
Answer: If you have a corded electric mower, then it will typically use between 700 and 1800 watts of electricity per hour. Cordless electric mowers, on the other hand, tend to be a bit weaker. Battery sizes are often between 40 and 90 volts, requiring 600 to 1400 watts of electricity to charge, depending on battery amps.
