The invention relates to a device for compressing combustion air, in particular a device for compressing charge air for an automotive combustion engine, with at least one electrically operated charge-air compressor ( 12, 14 ), which features at least one compressor impeller ( 24 ) that is arranged in a compressor space ( 22 ) and driven by an electric motor ( 18 ), as well as with a second, additional charge-air compressor ( 32, 34 ), in particular an exhaust-gas turbocharger ( 34 ), that is connected serially to the electric charge-air compressor ( 14 ), which are connected to one another in terms of flow via connecting means ( 30 ). It is proposed in accordance with the invention that connecting means ( 52 ) are present, which make it possible to guide already compressed charge air into the compressor space ( 22 ) of the electric charge-air compressor ( 14 ).
