Should be able to but here’s one thing to keep in mind. The inverter it uses to generate the 120V is probably pretty bad so the P10 will clean up the sine wave as best it can by a factor of maybe 10.
The waveform from a Generac (22kV in my case) is nothing like a sine wave, and my P-15 Power Plant will take it for a little while, then shut off all outlets, indicating “Short” (the outlet display also changes from green to red.) However, the P5 powering a router, LG OLED, LHY switch, and 100 watt LPS (for router) does pretty well, although I avoid using the TV just in case. But it’s nice to have wireless internet during the outage(s) The P5 has also shut down at times, but will usually work after a power down / power up while on generator power.
