Where this data comes from
max_power_mw and power_levels_mw are DJI's own figures from the O4 Air Unit Series user manual v1.0 (section 4.3 Setting Transmission Power, p17): 'DJI O4 Air Unit: The maximum available transmission power levels are 25mW, 50mW, 100mW, 200mW, 400mW, and 700mW.' These are output-power levels in milliwatts, the same quantity the analog listings in this column print, and NOT the Transmitter Power (EIRP) dBm figures DJI publishes elsewhere - EIRP includes antenna gain and is a different measurement. Available levels are lower in regions whose regulations cap them (DJI states this in the same block).
