Tested:
1. At home on a sunny day (all day, angled towards the sun). It charged two phones, a 10,000mAh power bank, and an e-reader. It probably would have managed more if it hadn't overheated around midday. It's a known issue: the higher the temperature, the less power you get.
2. Strapped to my rucksack. Most of the day was spent walking through a forest or with the sun in front of me. It topped up the power bank and half the phone's battery. My requirement for a solar panel is to generate enough energy once every two days for a phone, a camera battery, a headtorch, and to store the backup power in a power bank.
Meets all requirements
Could be lighter

Works as it should, it charges Xiaomi 13(4500mAh battery) in an hour when the sun is nice,
Unfortunately, I hardly charge at all when I move,
Which is a shame, but so be it.

In full sunlight gives 3A per hour recharges powerbank swissten 30000nAh by 10% which is great
You need to watch the angle and angle to the sun
The display shows the current so the angle is easy to find
Nothing yet.
The feet are weaker

I was surprised how well it charges the phone in optimal conditions, on the contrary, if it is under a cloud, it is unusable. It can also be used to recharge a power bank and then recharge your phone at night when you don't need it.
It really works
Charges in direct sunlight with the right angle, roughly like a wall charger
It can be folded
Includes mobile phone pocket
Includes practical eyelets for hanging
Works well in the morning and evening, just need to shoot in the sun
More for enthusiasts, there won't be many practical use-cases
Performance drops rapidly in improper rotation or in partial shade
It takes direct sunlight, you can't charge anything with peripheral light

The panel is nice, it charges nicely. But I don't really understand the 28W marking, because realistically I got a max current of 2.1A, which at 5V means an output power of just under 11W.
quality construction
really gives a lot of power
PET top film, i.e. it will degrade over time
does not give 28 W

It's working. Of course, it takes patience. During the day from approx. 7:00-20:00 h. recharged my 20000mAh power bank to almost 75%. And of course I didn't have acceptable conditions (trees shaded, proper tilt) The most the charger got so far was 1.9A in direct sunlight For those who are considering this I recommend it. And one more thing. If you want to charge with this so straight to the powerbank because of the fluctuating current.
so far satisfaction I will order a second I want to be independent of el. from the network
the support legs are not very stable (probably my fault and I had a bad base but they kept breaking so I couldn't adjust the tilt)
