The air-Q is supplied with the necessary power via a USB-C plug-in power supply (5 volts). In principle, any USB-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 air-Q's demands for a constant power supply in order to provide precise measured values. The air-Q can also be used wirelessly - i.e. it can be supplied with power via a USB power bank / rechargeable battery / battery.
