AC-to-DC (rectifier; GaNprime, GaN) and DC-to-AC (inverter) are inefficient conversions: it wastes electricity as heat.
Residential and Commercial AC electrical systems have a GFCI ground loop (for the ground pin on standard AC adapters)
WAV: Watts = Amps * Volts
# USB power specs (DC)
7.5w = 1.5amp * 5volts # USB
15w = 3a * 5v # USB-C
100w = 5a * 20v # USB-C PD
240w = 5a * 48v # USB-C PD 3.1
# 110v/120v AC: 15amp; Standard Residential AC in North America:
1500w = 15a * 100v # Microwave oven
1650w = 15a * 110v
1440w = 12a * 120v # AC EV charger
# 110/120 AC: 20amp
2400w = 20a * 120v # Level 1 EV charger
# 240v AC plug: Dryer, Oven, Stove, EV
4800w = 20a * 240v
7200w = 30a * 240v # Public charging station
9600w = 40a * 240v # Level 2 EV charget
14400w = 60a * 240v
120000w = 300a * 400v # Supercharger v2
120kW = 300a * 400v
1000000w = 1000a * 1000v # Megacharger
1000kW = 1000a * 1000v
1MW = 1000a * 1000v

(Trifuel) generators do not have catalytic converters.
Wood stoves must be sufficiently efficient; and can be made so with a catalytic combustor or a returning apparatus (and/or thermoelectrics to convert heat to electricity).
