I just found that some circular have logic-defying efficiency.
For example, dewalt DW368K specification says 15 Amps motor, and the max output is 2200 Watt. However, the input power is 15 Amps x 120V = 1800 Watt. How could it consume 1800W of electricity and produce 2200W of power? It must have an effiiciency exceeding 100%!
Another example: Milwaukee 6391 has a 15 Amp motor and claim the saw has 3
1/4 horsepower. Since 1 horsepower = 746 W, 3.25 HP = 2424.5 Watt. It is even more efficient than the dewalt!!Why hasn't these more than 100% efficient machines made the headlines?
