How is air-Q supplied with power?

Response:

The air-Q is supplied with electrical power via a USB-C plug-in power supply unit (5 volts). In principle, any compliant power supply unit can be used with the measuring device. However, we recommend using the original power supply unit supplied: This is a tested power supply unit that not only meets the legal requirements (EMC) but also the high demands of the air analyser for a constant voltage supply. If you do not have a power socket available, you can also supply the air-Q with power via a power bank.
