The only experience I've had with the plug-in coolers is I've seen them run down a car battery overnight - So I'm assuming the power usage is too high.
These units usually use a "Peltier effect" cooler system, which is power hungry compared to conventional compressor based coolers (for equivalent cooling).
On top of that are losses factored in by the use of the inverter as well.
