    Reviewing the iMars SP-B40 40W Solar Panel. The panel came packed in a cardboard box. Inside the box in the panel wrapped in a plastic bag. The panel comes with an information sheet and accessories. The accessories can be found in a pocket along with the panels output distribution box. The distribution box has a raw output 21V/2A and two USB outputs both of which support fast charging with the USB port offering 5V/3.4A 9V/2A and the USB C port offering 5V/3.0A 9V/2A, 12V/1.5A. The accessories supplied are 1 X Alligator Clip Cable, 1 X DC-DC Cable and 4 X Carabiner Clips. The panel is made of a tough synthetic material which should last a long time. The panel has several loops of material along it's edges which allow the cariabiners to be used to mount the open panel to a backpack so you can charge devises via solar as you hike. In testing the output I was only able to get 24W as can be seen in the test output photo. I think the reason for this is that the day was hot and the panel was laying on hot concrete with also the solar controller type playing a part as it pulled the voltage down to 13.37 volts without any power tracking compensation. Overall I am very happy with the solar panel and it has become part of my motoring kit of tools for four wheel driving use and camping.

    The product arrived packed as always on Banggood's characteristic white bag, arrived in Italy after about 12 days. Inside the bag was the product box. In my opinion that bag is too unprotective, because it doesn't protect the package adequately, however it all arrived without any damaged pieces. As soon as you open the box it is immediately inside another transparent bag with the Q.C. Passed stamp, so there was also a quality check before packaging the product by the manufacturer. It seems well built with very good quality materials, it also comes with 4 carabiners and two cables to connect a PC and to the batteries of the cars/motos etc. (12v).I tested it with little sun but the fast charging of the cell phone is activated anyway so the current generated it is sufficient (with ~1A of current).I am satisfied with the product. As always, I encourage Banggood to improve the packaging, to also reduce damaged goods during transport (although this is not the case).In my opinion this product is great for when you go on vacation, maybe in the mountains and want to charge your cell phone or even your PC. It can also be very useful in case of emergency if the battery of the car/motorcycle/camper is discharged due to the forgetting of the lights on, well with these panels you can also charge the batteries to 12V!!! in addition to the cable to connect the PC to the photovoltaic panel is also supplied a cable with the clamps to connect precisely the batteries mentioned above. Unfortunately, I was unable to test the PC because my laptop does not have the connector compatible with the one that came with it, here's maybe an extra treat that wouldn't hurt could have been just an adapter for the various laptop sockets. To conclude I must say that I am really satisfied with these solar panels, comfortable and functional!!!!!
