I need a small solar source for my bug-out bags for my significant other and myself. This fits in a regular sized backpack. I did an early test of the built-in USB. Daytime but cloudy completely overcast day with some gray. Layed it out flat. Got a half amp on from the USB. I can fully charge my Garmin inReach satellite communicator in a few hours with that. Looking forward to testing it on a sunny day. Hope to get 2 amps from the USB.
Did a more thorough test with the raw solar output jack today. Ran it through a MPPT charge controller and charged a LiFePo4 battery. Measured current with a clamp meter. Oh YEAH! It was exactly what it should be. For my location (upstate NY), date (October), and time of day (1PM) , I got exactly what I was supposed to get ... even with the foldable panel just propped up at approximately the right angle. There is no doubt that this panel will produce 60 watts in the summer if you have an MPPT charge controller. It is sized well for my purposes even in the winter for charging a battery pack that will recharge a few flashlights, hand held radios, etc. Great product. I have 2 and am giving one to my daughter.
Added: I gave both to my daughter with the necessary cables and controllers to run the two in parallel or series. I added an inline meter so that she can see how well it's charging her lifepo4 battery pack. Now I'm looking at this as a third purchase for myself again. I know it's good stuff because I (a degreed electrical engineer) thoroughly tested it myself.

You can lead a horse to water but you can't make it drink. The point is that these panels, and others I've purchased are priceless! The best part about it is it's multiple ports for extra devices, and it's great charging speed. Don't be a dead horse, get 1 today!

I used the solar panel to charge my Progeny 300 watt solar generator. On a nice sunny day I was charging at about 33-35 watts. That mY not sound like a lot but when plugged into AC outlet to charge, the Progeny only inputs 35 watts. The panel is very compact and comes with plenty of cables including a multi-cable with lightning, USB-C and mini USB. The panel has two USB outlets so you can charge your phone or tablet right from the panel. So far very happy with product.

Camping in the bush for over a month each year. These keep various electronics charged up in a timely manner. To be honest, the Keshoyal works better than my Goal Zero. More adapters were included than I'll ever need...but nice to have. No complaints. Putting this away until next year. Hope it holds up for multiple outings.

Charged up my cell phone super fast and a solar generator in about 5 hours. I live in a very sunny climate so solar works good here. I'm very happy.

Works as it should. Had mine outputting 48 watts of power during the fall setting sun. Happy with my purchase and I would try other products from this brand.
