I’ve recently found several great USB powered or charged devices.  What are your favorites?

Here are some of mine.

A battery clip fan.  It runs all night on a charge and even has a outlet to power other devices.  Very small.  This specific one I noticed is no longer on Amazon.  I have three, two for the bus one for the house.
Solar remote light with USB charge and outlet for other devices.  Love it, keep the remote by the door to give folks light as they enter the van. Can charge if left in skylight.
USB flash light and USB head lamp.  I leave these in the glove box and charge up now and then using the GW glove box charger.  This way friends always have light.  The flashlight also can power other USB devices.
I also have a simple USB battery power block I use in the house if power goes out.  It is small so I could bring camping. Good to charge a phone about three times.

So, what USB devices make your van life more comfortable or fun?

I think there are lots of devices out there that we might not no about
