    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.

    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.

    iMars portable solar panel 25W This is a nice solar panel that can charge phone and 12V batteries via 2 port. 1 USB QC that handle 5V, 9V and 12V and a DC output (19V via a 5.5mm connector). To load 12V battery you might need a special cable. It starts producing power also under cloudy days. It is not rainproof, therefore you should not leave it outside permanently connected since it is not weather-proof. It features 2 holes to hang it to hooks. Very advised for camping.

    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 solar panel working well, it can feed about 36-38W. One detail, which i haven't found in the description: if you connect a consumer to both the USB and to the jDC ack port. on the DC jack you will have the same voltage as on the PD USB port. So if you put your QC 3 capable phone to charge from the USB port and it negotiates a 9V voltage, you will have 9V on the DC jack port too.
