   If they exist, I haven’t yet found them… But there’s battery back ups, that store hours of use them, that people use to plug in grow lights. It’s an intermediate option I’ve seen.

   I use the ones that has a USB cord. And purchased a USB hub so I could plug in several at a time. Hope that’s helpful
