This is a pretty basic panel, just a fold out panel with no props or fancy features. It's also cheaper than comparatively powerful panels. It comes with a full set of optional cables. There's also a solar charge controller that appears to be used to charge certain types of batteries directly. I suppose if you need it you'll know what to do with it; Instructions are minimal. All in all, this is a good compact package. To test it, I turned it on from about 3:00 a.m. to 4:15 p.m. on a cloudy day (several full sunny days, some clouds passing) to charge the battery of the POWERADD 280Wh portable power station, which runs at 50 % was loaded . During this time the power station has a power consumption of 10 to 42 watts (mostly stable around 28-30 watts) in the sun and between 50% and 63% charged. Maybe I could improve the situation if I paid more attention to the direction of the sun. The photos show the panel as installed (secured in the power station) and my power station's LCD panel after 75 minutes of charging.
