Workshop Power Consumption Calculator

Enter the hours per day you plan to use each tool. Click "Calculate" to see the total daily consumption (kWh) and estimated peak wattage (W).

Application Running (W) Starting (W) Hours/Day Daily (kWh)
Electric Drill (3/8") 0.00
Bench Grinder (8") 0.00
Air Compressor (0.5 hp) 0.00
Air Compressor (1 hp) 0.00
Reciprocating Saw 0.00
Circular Saw (7-1/4") 0.00
Miter Saw (10") 0.00
Table Saw / Radial Arm Saw (10") 0.00
Weed Trimmer (electric) 0.00
Chain Saw (electric) 0.00
Leaf Blower (electric) 0.00
Lawn Mower (electric) 0.00
Total Daily Consumption: 0.00 kWh
Estimated Peak Wattage (if every tool starts at the same time): 0 W

Notice: This result gives you a maximum daily consumption. But think about it: if you use battery-powered tools, you can easily reduce your charging time

More importantly: More importantly, identify your high-consumption appliance to see if there is no other option.

Advice: Based on your estimated peak wattage, we recommend that you ensure your power system is sized to handle a little more than your peak demand. This extra margin can help account for unexpected surges and maintain reliable performance.
