It arrived well packaged and delivery was quite fast. Features a sealable pouch to store cables or thin USB devices. The two output ports line inside the pouch. Output port support up to 9V. It is waterproof and the build quality is pretty good. The SP-B21 model doesn't come with any accessory such as carabiners or charging cable. By using carabiners you can hang this solar panel to a backpack and use it during walking. Unlike other solar panels, this can be folded while the carabiners are attached. Solar panels are more efficient if the panels are at a 90 degree angle to the sunlight beams. I adjusted the panels at almost a 90 degree angle to the winter cloudy sun, ran a test and got a max of 1.5A 5V output power. It wasn't the sunniest day so in summer sun the output power will be greater than this. I'm a big fan of solar power so the iMars SP-B21 is very beneficial while camping. I'm happy with this portable solar panel USB charger because I can always charge my Li-ion Ni-MH batteries and phones during the day. The brand also has more powerful chargers with four panels and DC output for laptop charging. I suggest to use solar panels in combination with a power bank or a smart battery charger.

Seriously, I am amazed by the quality or the product (and packing). I wasnt able to use it ( i just got it and its dark) but the quality is just great. I will try to use it during day and will add how it works.

Заряжал Redmi note 8 pro смартфон был включен, в пасмурную погоду, переменной облачности - за 1,5 часа зарядился на 12% считаю это нормальным.

Zakupiony towar przyszedł w 5 dni, to całkiem super wynik! Wielkie dzięki. Sprzęt działa, i oby jak najdłużej. Trudno mi było uzyskać parametry znamionowe ale sprawdziłem od razu: 21.03.2022 godz. 16, niebo bezchmurne, udało mi się uzyskać w szczycie ( zależy od kąta ustawienia względem promieni słońca) nawet 1,5 A. Średnio 170mAh w 10 min. Ta wartość będzie jeszcze lepsza latem. Może komuś przydadzą się takie dane. Ogólnie sprzęt trochę mniejszy niż kartka A4, lekki, na biwak czy wypad w góry do ładowania powerbanka na pewno się przyda jako alternatywa w razie "W". Jeszcze raz dziękuję.

I got this in time and in perfect condition. Really high quality material. It charged my phone even in dim light, however, I have not fully tested it yet but seems to work. There are two regular USB connectors in the top pouch. Also it comes with small loops to attach it on something.

Small, compact, easy to carry, does it's job. I could not do fast charging with it on the other hand, so I rather charged power bank with it
