Can I use the USB port to power a LED lamp?
I tried to look for the information in this forum and in prusa documentation, but I cannot find what can be plugged on the USB port - besides USB stick.
Will it be ok to plug a 1-2 watt LED lamp such as this one:

Or is it a bad idea?
Thanks in advance!

I needed to see my print more clearly one time when I was printing with black filament, so i plugged in a small 5v usb lamp in the socket. I haven't tried something long term though. I still use the port to load my gcodes.

I have been using the led lamp powered by the mini's USB port for months. You have to be careful not to draw more than 500 mA of current from the port, as @neophyl pointed out.
The lamp you posted is rated for 1.2 watts and the USB port is 5 volts. Therefore it will draw ~240 mA of current => you should be safe to use this lamp 👍

Thanks for all your answer. Depending on the final led solution (the one I posted may not be the final), I know that I could use the USB port.
