I’m struggling to find any communities on Lemmy, maybe someone can point me in the right direction?
It’s a really dumb and minor question but it’s driving me nuts trying to find a decent solution.
I’ve got some of those metal outdoor lanterns that have a small round solar panel on the top and an LED. They work great in the summer but there just isn’t enough charge in the winter for them to get fully charged… the problem is, EVERY single one I’ve found ONLY charges when it’s turned ON.
There seems to be 1000s of replacements on Amazon but I’ve not found a single one that charges while off…
I’d really like some that I can keep off but will charge anyway so I can turn them on when I’m actually using them in Winter.
Dumb question but maybe someone can point me to a Lemmy community that can help!

My understanding is that the purpose of the off switch is to disconnect the battery from everything so you can put the device in storage. The battery cannot charge (or discharge, much) when it is disconnected. This function is necessary so that the battery doesn’t become permanently dead in the store/warehouse before the device is sold to you. Adding in the feature as you describe it would cost more – profit margins on this kind of device are razor-thin so this is not likely a viable product – and there’s not much demand for garden lights in winter, so economies of scale would be difficult to achieve.
You could design it yourself to work the way you want though! It would not be that hard or expensive, probably you could fit it in to your current devices. A few ideas come to mind, although they all require some OK programming skills and basic PCB design skills.
These devices also tend to be highly cost-optimized – as a ‘cheap hack’ you could try taking two apart and putting both panels on a single device (in parallel, NOT in series. Be sure to observe polarity). It’s very likely that the panel and battery capacity are engineered to be just barely enough to serve as a summer garden light at the latitude of the target demographic (again, razor-thin margins). This is most likely the fundamental reason the light does not behave the way you want it to.
An additional consideration is that the performance of many rechargeable cell types decreases with temperature.
Anyway, I hope that, er… sheds some light on the issue!
I’ve never heard of ones that don’t charge when the light is off…
I’ve got a bunch of solar lights in my yard, and I have them set to “motion” tho.
Some have been up for years now, and I’ve never noticed any not turn on when they should. I don’t know if they’d keep charging if switched to “off”
So maybe switch to motion?
And if you want them to stay on, you’d just have to move the selector over to “on”?
I’ve never seen any that aren’t complete crap. If you buy them you should plan on replacing in two years as they decline in performance quickly. If they aren’t too far from the house would bite the bullet and get some good low voltage lights you can run via Smart home and don’t look back.
