I have the 20Ah version. In stronger sunlight, the solar charger stops charging because the battery part overheats (probably the thermal protection goes off). The solution is to shade the main part, preferably with a light object, sometimes just turn it 90 degrees. This will lose a fifth of the solar power, but the recharging will work. I used this for a few weeks, on average half a day of solar charging was enough to charge a mobile phone with a 5Ah battery. I would welcome solar power measurements for the sake of adjusting the panels to the sun.
compact
Parameters of the solarium and the battery are inflated.
overheating during solar charging
no solar power measurement

The performance matches the price. The powerbank was delivered with 46% and recharged 2x phone by 30% and 2x El. cigarettes by almost 40%. You can't compare to products costing several thousand. Charging via solar is slower, but I leave the powerbank in the sun all day and need to charge overnight, so it meets my requirements. Set 12.08.2025 at 9:00 am. in the sun and after an hour recharged to 5% from zero. Thus, leaving most of the day in the sun to recharge the device in the evening / overnight is fine.
fast charging from the powerbank
wireless charging from a power bank
supplied with C/C cable

Overall for me great and I would recommend it. I have no problems so far and the price/performance ratio is adequate for me.
large battery capacity
solar panel that is functional
affordable
charger included
wireless charging
sometimes shows different percentages than the powerbank actually shows
it needs to be recharged frequently, not only from solar panels
is heavy (but it's probably obvious why that is)

[subjective] I don't believe it would last me mechanically and I don't believe it would charge in six months.
charges well
three ports
fortelna box
those panels practically do not charge, moreover, quite indeterministically (1% per hour, sometimes 3% in about 2h, sometimes in 40 minutes nothing. )
an unfortunate suggestion: if the manufacturer says that it should not be in the sun for a long time, he should have designed the product so that the panels can be separated
quite heavy (2x as much as a power bank of the same capacity without solar panels)
MAIN POINT: those features (panels) that it has in addition do not add enough value relative to the negatives.
. which are weight, dimensions, but also mechanical design - it's hard to position it somewhere (to an angle of ~ 45˚ - and when folding it again there is a risk of dirtying the panels )

Awesome, just could use integrated cables like the previous version. Wireless charging is surprisingly fast and the magnets hold the iphone in place when the right position is found and without a case

Handcuff
No cables like the previous version

I've already described everything in the pros/cons section. There's no point in repeating myself. I definitely recommend this powerbank.
Capacity
Output wattage
Really functional panels (but don't expect a miracle, it's more for emergency use)
Built-in flashlight
Waterproof (at least supposedly, I haven't tried it, but it will be water-resistant at least)
Resistant to mechanical damage
Display with numeric charge indicator
Price
Maybe the weight, but that's just the tax for the benefits. I don't even mind, I always have a heavy backpack anyway: D If you want a light one, buy a regular one, like from AlzaPower.
