A check-in on how our homemade oil lantern is doing from this past summer, shown originally in this video: Exclusive 130: How To Get By Without the Sun

This made me laugh. I feel this way sometimes when I start some long excursion into the backcountry the same day that deer season starts.
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 ...
