What does the 170 W rating mean when the adapter is connected to a ThinkPad P50?

It supplies up to 170 watts at 20 volts and 8.5 amps, matching the power draw the P50 expects from its original charger.

How does the barrel connector limit which ThinkPad models can use this adapter?

The barrel tip fits the P50, P51, P52, P70 and P71 charging ports; other models with different tip sizes will not connect.
