I'm hoping admin support will read this as I desperately need to know the voltage and wattage of their external usb burner as I cannot use it until I do. There was no instruction manual with the machine and no sticker or writing on it anywhere to tell me. I have emailed MTU support but heard nothing so far. I have an electronic company here that can sell me a transformer but they need to know voltage AND wattage so they know what power it draws. Admin support please read this soon!
