parking power: powerbank or solar?

[CharlieGirl]

I actually have a flexible 100 watt solar setup with a 100Ah AGM battery on my pick up truck. The solar panel is glued onto the roof of my truck shell. Its to power my 12v fridge while camping. Haven't really had a need to have the camera run 24/7 but I will probably put the cameras on the second battery to run on parking mode for the heck of it. I have a battery isolator that is also a solar charge controller. I did have stuff stolen from the back of truck shell when I forgot to lock it. The camera running while in parked mode would have caught the perp.

Please let us know how you get on. Whatever you achieve will be much harder here in the UK where there is less sunlight - and of course if it's behind a windscreen. From what I read solar panels should work fairly well still behind a windscreen, even if tinted but with less efficiency. BMW (I think it is) have some model with a new type of ultra thin flexible solar panel bonded to the roof of their vehicles and of course Tesla are big into the idea of solar powered cars.

I bought one of these last week: https://www.amazon.co.uk/gp/B073QQPKVY
Lithium iron phosphate, so safer than typical li-ion or lipo power banks. See: http://batteryuniversity.com/learn/article/types_of_lithium_ion

If it's truly 20,000 mAh it should power the average cam for 24hrs continuous recording perhaps? In parking mode, you'd need to do some research about what each cam draws to work out the consumption. Or just buy one and use trial and error?

Thanks for this post, really useful. That's the same chemistry used in the Cellink B too. Your link was handy. I did some more investigating and found this info useful too: https://www.batterystuff.com/kb/articles/battery-articles/lithium-battery-overview.html
As well as being much less likely to try and kill you with fire they also have much better charge cycle life too which is a big advantage in this circumstance of course.

The long and short is that I've just ordered one too!

If I do explore the solar option further I'll have to look into how Lithium iron phosphate copes with that kind of charge. A task for another day, along with trial and error for working out the draw from the dash cam.
