USB powered air purifiers

USB port

— devices with this function allow you to power the air cleaner not only from a stationary power source such as a PC or a USB network adapter, but also from a laptop, tablet, or even a power bank. Car USB adapters are also available. The downside is that the power of such a power supply is extremely low, and it is suitable only for the most compact humidifiers with modest performance characteristics. Among the connectors, you can find microUSB and USB-C.
