Travel Mode Question

I have a 2 WYZE Outdoor Cams, I have set-up. However, I would like to switch one to Travel Mode. I have gone through the steps several times, and even though the WiFi connection is excellent, camera is 98% charged and the yellow light is blinking I am unable to connect. Also, since Motion Detection is unavailable in Travel Mode, is there any restrictions /recommendations in plugging the camera’s USB into a USB port connected to a cigarette lighter? Thank you!
