The "2200" watt rating seems to be calculated from the motor starting current, which the same reviewer measured at about 21 Amps for a brief period -- like the period during which the house lights dim when you hit the trigger to start the drill
Seems that they are using the same rating approach as those vastly overrated household vacuum cleaners, that used to boast about "peak horsepower" until the UL and CSA put a stop to it.
Actually, the brake to locked rotor horsepower ratings of vacuums is a little higher than you'd calculate using the measurement of inrush current, but for the most part, you get the idea. It's an effectively "imaginary" number with no application to the end-user.
.... could be some one is making some weird calculation with PeakVoltage instead of RMS.... it is possible.... 120V 60HZ you normally see is RMS voltage. Any one who's a real electrical engineer should be able to confirm this. I am just an imaginary one.

2800W/170PV = 16.5AMP....
No, because watts do not work that way.
It might do it for a millisecond.
Yes, I'm aware that your answer was not completely serious, but here's a serious response:
You'd be surprised about how much current you can pull from a 20A breaker, and for how long.
Also, I've never seen a breaker that can interrupt a current in a millisecond.
The fastest reaction time I've seen is around 1 cycle, which at 60 hz is around 17 milliseconds. And to trip a breaker that fast, you'd need to exceed the magnetic threshold of the breaker, which looking at the trip curve for Square D QO breakers, is between 9 and 22 times the nameplate rating. i.e. you'd have to exceed AT LEAST 180A to trip on the magnetic.
On the thermal detection, at 30A draw (1.5x the nameplate rating of a 20A breaker), a QO breaker will take between 30 and 180 seconds to trip.
