Bear in mind that inverters tend to be inefficient except at full load. I don't recall the exact numbers but running a 175W inverter for a (10v x 2a =) 20watt device would probably be very inefficient. If the XO can run off raw ships' battery power I wouldn't be surprised to see numbers showing way less power used.

Likewise Bluetooth and Wifi both have provisions for automatically adjusting their transmit power, although I have no idea of the maximum power available to the radios in those two computers. 25-100mW seems typical for laptops but 600mW is available if they choose to use the hardware for it.
