    5v usb power systems?!

    Hi all,
    Just set up my first off grid system, not a huge one but enough to run my home office during the week and daily use at the weekend.
    On thing I'm struggling to tidy up is all the 5v items I use, Alexa, Raspberry pi's and a few other one automation devices/ESP32's, I'm looking for a solution to power these direct from my 24v battery array but can anyone suggest a solid DC to DC converter that will more efficient than a couple of plug-in 230ac- 5v usb transformers?

    Thanks
    James

      Boating catalogs may have some 24-28V USB devices. But it's doubtful that they will have efficiency specs. Good Luck
