It works at 11:00 in full sunlight in spring, providing 0.23A when lying flat. Slow but stable. The device is well-made and carefully crafted. Includes instructions and assembly system. Great for charging a power bank.
I am satisfied! Tested in the autumn sun, whose light is dimmed by light clouds. Result: voltage 4.87v, current 0.66a (power 3.2w) the charging process accepts both a mobile phone and a large power bank! These are good results. Thank you.
Advice for everyone: take only the type with 6 blocks. I think that fewer blocks make no sense.
It's fine, it works as indicated in the advertisement. If it's a sunny day, it works well. If it's slightly cloudy, the charge is unstable, so it's more recommended to use it to charge a power bank and from the power bank to charge the phone.
It's practical, takes up little space, and if you're going to the countryside or the mountains, it's ideal to stay connected.
It arrived well and within the expected timeframe. I haven't used it yet to see if it works well, but it feels of good quality.
