Just purchased a Flex sensor - are there good power adapter options other than the ones sold by Purple Air? What specs should I be looking for if trying to find a generic power adapter from another retailer? Sorry if these are basic questions - I’m very new to all this. Thanks!
Depends where you are installing it. I’m new too and I purchased the outdoor power cable which is just a weatherproof USB power supply that provides a micro USB. I’m not sure why they are not using the more current USB C options. Any 5V power will work.
You can use any standard USB micro cable with a 5V charger. I didn’t buy the power adapter that it comes with and mine works perfectly.
