I feel like I always think of solar punk as a macro thing where a lot has to change but there are still smaller wins we can implement, what have you been doing?

Talk to me about these cheap power banks - what kind of cheap are we looking at here?

20€ for 3 solar panels and a powerbank.

The powerbank itself isn't that big. But it charges fully in 4 hours and it is really easy to cut them up and extend the cables to put the solar panels wherever you want. And it powers every USB device.

You could also theoretically solder the panels in parallel to charge even faster. But I just connected 2 of the powerbanks with a USB splitter to get 1 USB output.

They also charge the powerbank with the slightest of light. Even just a light bulb is enough for it to start charging, lol.
