An essential piece for a moment of urgency, it came to me alone with two hooks without instructions or a set of cables to charge different devices as it appears on the website, in this aspect I will contact the seller who is AliEspress, and I have to say, Not the value is the detail, still the item is a good purchase, advised your purchase because it can get you out of many unexpected difficulties

It works well. According to the amount of light, the charging speed is very different. Indoor lights or cloudy days do not work. Useful in clear and strong light. For emergency use.

The monocrystalline panels have good performance. It can charge mobile batteries, folds up small, and takes up little space for storage. I think it will be useful in future emergencies. I also feel that it is a very good learning tool for children.

Have had this going for the last 2 days in full sun no clouds and all I was getting was a constant 3 watts. Far from the wattage claimed for this product. Very disappointed.

Until I really tested it, but it works and charges under direct sunlight no worse than sockets
