We're outfitting our new motorhome, and I want to run a LaCrosse projection clock/thermometer and maybe a separate Lacrosse indoor/outdoor thermometer on USB outlets.
I was all ready to cut and splice some cables when I realized those units use the same size DC connector as the Davis stations, and the same approximate voltage.
I had previously purchased the 6627 Davis USB power cable from Ryan at Scaled Instruments, and tried it.
https://www.scaledinstruments.com/shop/davis-instruments/davis-6627-usb-power-cable-for-vantage-pro2-and-vantage-vue-consoles/ It works perfectly. So, if you have a 4.5-5 volts device that uses that small diameter power connector that you want to run on some sort of USB outlet, give the Davis cable a try. I just ordered 2 more.
