    Chegou rápido no Brasil. Anteriormente já havia comprado outros 2 painéis, agora comprei mais 2. Liguei 2 em paralelo e em série com outros 2 em paralelo, para obter tensão maior com corrente maior. Utilizo um MPPT MPPT5025A-DUO MPPT 25A 12V comprado também na BANGGOOD que reduz a tensão e aumenta a corrente de carga da bateria. O painel SP-P50 produz na realidade de 35W a 40W. O painel é robusto pois suportou o maltrato do transporte. Olhe nas fotos como chegou a embalagem. Nos anteriores a embalagem foi muito melhor. Recomendo a BANGGOOD melhorar a embalagem atual. Gostei muito dos painéis.

    The solar panel arrived quickly, packed in a box. It works when the bright southern sun gives out 0.4 A. It is suitable for charging non-powerful devices. More powerful ones, such as a phone, will require more power. In general, I liked it, you can use it. It is quite possible to charge a flashlight or other device. Size approximately 60*40cm

    I got a 50W panel. Unfortunately, I couldn't make a perfect measurement without tools, but I'll write down what I did. For the measurement, I created an Arduino + Photoresitor. I put a display on it that measures between 0-9. 0: little light (sunset, sunrise), 9: I light directly on the solarresitor with strong led light. As a consumer, I used a 5V powerbank that can be charged with 1A. Powerbank consumption ~120mA from the network with my measuring tools. Panel results: 9:75-100mA, 8:6-74mA, <=7: I couldn't measure it. I'm afraid that the measuring instrument takes off too much, since it didn't charge the powerbank with 10A measurements and only 120mA is measurable. Without a measuring instrument, a USB lamp is fully lit even at 7 brightnesses. The brightness may have gone below 7, but unfortunately my Arduino instrument gave in, and in Hungary at 6:30 on October 29, the light was quite tolerable.

    You can safely on nature, on a long rest, here you and lighting and charging for your gadgets. You have to buy a battery, light bulbs and some wires before and you will be happy. Take it, you will not regret!!! The product is VERY recommended.

    I am surprised how fast this solar charger is charging my phone. And it's basically free energy. It made me think about putting solar panels to charge my entire home.

    very nice panel and made with excellent materials. it looks sturdy. I exposed to the sun and the led turned on immediately to signal that it works. Now it remains for me to do more tests and see how it behaves.

    The battery and cable came. There are two connectors. For charging, you need direct sunlight.

    Great 25W Solar Panel, easily charges a mobile phone etc. It is also great for connecting to a Nitecore UMS4 charger which in full Sunlight can charge many different types of batteries. This is great for charging torch batteries when no mains power is available. Only the 25W version is suitable for this charger.

    The quality of the processing and appearance is good. Charging your phone is fast and does not need a voltage regulator. But this does not apply if you want to charge 12 in the battery,here is the controller necessary. But it is a 30-35W panel compared to a 30W panel,which I have had for a long time. Good price-performance ratio. I can recommend.
