    Just a small pannel. Don't expect too much. It will charge a older smartphone with 2000mah lipo battery directy connected to the pannel's usb but it struggle for hours with a 4000mah mobile phone. You should opt for the dual panel setup and use a battery with the contoller if you wanna have some better results. The pannel outputs up to 300 milliamp in direct sunlight only and temperatures up to 28 celcius. When things get really hot the panel cannot deliver.

    It works. Hardly 40W power from this panel is possible. I think 10-15W are more realistic numbers. One can estimate it from 1 kW per square meter of Sun power under proper conditions. Panel is approximately 0.2x0.4=0.08 square meters. For 20% efficiency one gets 16W of electric power, for 15% - 12W, etc.

    Less power output than advertised. They should cost less. The plastic bends and gets deformed if you put it in direct sunlight in hot places like the car dashboard. It wont work on really hot days like 35 deg celcius or more.

    The panels have become slightly cloudy during transport ( rubbing against each other). The manual does not contain complete information and shows the application for which this equipment is certainly not suitable. Good cable with different connectors for charging. So far, I've charged my old Lumie up to 50% for a couple of hours, and it's still charging, and we'll see how much it can charge. To charge the POCO x3 I think these two panels are not enough.
