These panels make a great companion to a solar generator. For my testing I connected this to an excellent Anker II 300 power station. We had a small tropical storm which was enough to take the power out for a day so I used this power supply to keep my TV and soundbar running. It did the job well. Although power was restored the next day, I decided to use this solar panel to charge Anker. In an ideal situation for camping or similar, the solar energy harvested during the day will replenish what has been lost at night and keep the supply going during use. The math tells me it's almost possible, but in this case it took me two days to refill what I was using. I didn't have ideal conditions because the yard is a jumble of trees and debris, so I placed the panel in an area that was sometimes shaded. The real test will come at camping if it's ever safe to go outside again. This is a well made panel set that meets the performance limit/size for single tent camping.
