    This is pure bullshit. They say power is 250 W. No way. You can take the 0 away, and we are near the truth.

    The controller is pure low cost PWM regulator. The 5V USB port is capable to delivery only 0,5A! The included cable is really thin and 2A current will burn it, don't try use it with load higher then cca 20W. The panel itself has USB-A and USB-C connector with same 0,5A limitation. The panel can delivery max. 20W. Overall - bad combination of components, the

    the product is very good I like it very much. Well, technically, the information is a little understated, so you'll learn by tampering with it yourself. Other than that, everything in the product sales visuals came complete. there is no shortage of product working. They don't charge you customs duty when you take out customs insurance, that's good. I ordered the product on 08.08.2021 and it was in the gum at 12.08.2021 and I was surprised to receive it on 14th. banggood outdid himself. it works very well in the vineyards with a solid battery supplement I recommend it ❤

    TR yaklasik klavye kadar bir urun. solar panelin arka kisminda bulunan usb ve typ c portu ile direk baglanti yapabiliyorsunuz. yaninda gonderilen kontrol cihazi ile ayar ve baglanti yapabiliyorsunuz. harika bir urun kesinlikle tavsiye ediyorum. yaninda bir de akü yada power bank gibi urun siparis ederseniz degisik projeler uretebilirsiniz. (EN) about as much a product as a keyboard. you can connect directly with the usb and typ C port located on the back. you can adjust and connect with the controller that is sent next to it. I would definitely recommend a great product. if you order a product, such as a battery or power bank, you can create different projects.

    This is the second kit, the first one had faulty controller. The controller has set-up three battery types, the b2 is configured to be used with LiIon battery. The manual has incorrect information about it. I measured solar panel, it's max. 25-30W of power. The panel has protective diode and can be safely connected in parallel with another one. The USB port on solar panel and controller can delivery 0,5A at 5V. Overall the kit is suitable for devices with small power consuption.

    The product works perfectly. In southern Spain at 10/11/2021 gives me a maximum power of 28W considering we are in winter. I see it very well.

    I got the package perfectly inflamed without damage. Proven and works great. It is cloudy and still gives 17.4V. I didn't measure the wattage but it probably gives 15-20W in cloudy weather. I'm very satisfied. I recomend. I will buy another solar panel to increase performance.
