This is a must need for everyone who travels often. At home I sleep with a bedside on 24/7. Not because I’m hot but because I need the sound. Anytime we travel and there is no fan , I struggle to sleep to the point I have downloaded sound apps on my phone but then it drains the battery. This fixes all that. It’s compact. Won’t take up much room in your carryon, suitcase , etc. and it fits on any surface. Whether that be a bedside or maybe even a baby’s room for white noise. It has every sound you could need; water, fan, nature, white noise, etc. You can adjust the volume as well. It comes with a usb cord to charge, so you will need a power block to plug it into but once it’s charged it doesn’t need to stay plugged in. If you have to have sound to sleep, then you need to invest!
