Hope this fits here.
It's not much in the grand scheme, but all of my everyday carry electronics are all solar charged.
Left to right: Cat S22 Flip smartphone, Bluetooth earbuds, rechargable pen light/laser pointer/black light/dog toy, and my Kobo e-reader.
They're mostly charged / topped up overnight from my 12W / 8000 mAh solar battery bank. I just throw it outside or in a window during the day and plug a USB hub into it to charge my devices overnight. My phone will usually go 2-3 days on a charge, but I've also got a 6W panel I stick in the window if it needs a little battery boost during the day. I also top off other things from the 6W panel, but those aren't exclusively solar like my EDC stuff.
Thought I was going to have to cheat a week or so ago. It was rainy and cloudy for nearly 2 weeks, and the solar battery bank was struggling to stay above 50%, but the clouds finally broke and my solar bank was able to fully recharge with a few hours of sunlight to spare.
Like I said, it's not much, but these have only ever been charged from solar**, and I think that's pretty cool.
** Except the bit of charge my phone and e-reader got from my laptop when I had it plugged into USB to flash firmware and add files.
My solar battery bank. (Not the best design with an integrated, non-removable battery, but has worked well enough)
Just realised, you could use it in hotels as well :-(
Thanks. That does sound way more useful then I was thinking.
