Thank you very much for your answer. I'm wondering if I can charge my USB OTG device while I take a puff or is the power supply interrupted?

Hello everybody, I actually bought a DNA 250 Color. Now I would like to run a little fan or air pump or something like that while my coils are getting heated. I thought I can use the 5 V of the USB OTG for that. Is it possible to use this as a power source while heating or is there some kind of XOR dependency between the 'powerbank mode' and the 'heating mode'? Do I need to run the DNA in the 'powerbank mode' or can I just use the 5 V somewhere from the board? I recognized that there are several test points on the PCB where I can measure something like 4.9 and 5.1 V but I don't know how much current they can provide. Thank you very much for your help!
