Yesterday was a perfectly sunny day here where I am. So I took advantage of the sunlight to test out several different solar chargers to charge up the same 50000mAh power bank. I thought you folks would find the results interesting. I certainly was surprised with the outcome.
One thing I had never done before when doing tests like this - which has always been a silly thing to overlook - is that I never before established how much charge the wall electric outlet in my house gives me within the same time frame that I am using to test these solar chargers. As you will see from the results, my smallest and lightest solar charger consistently performed the best and performed as well as my wall electric outlet. The larger watt solar chargers performed the least well.
The 15w solar charger is the smaller, two-panel in the picture. The 22w solar charger is in the background and contains a third panel. Obviously, smaller and more compact is better, especially if higher watt solar chargers don’t offer any advantage in performance.

I found this video interesting as it relates to conversations we have about the true nature of things, what is really important and what is not, and how little importance some things have depending on the needs of the moment.
For example, this guy and his fellow soldiers, while being shot at would just dump their blankets - the blankets were totally unimportant to the immediate goal of staying alive. This meant later suffering, but at least they were alive.
I think about this sort of thing all the time when seeing guys building elaborate, beautiful shelters in the woods. When you’re hungry and lost, or simply traveling through the wilderness, nobody is going to care about building an elaborate shelter. You’re only going to care about conserving energy and using energy for only things that are absolutely necessary in any given moment.
This means sleeping under a rock outcrop, or a fallen tree, or just trying to get through the night under your sweater and some leaves you scrounge ...
