A solar panel is sufficient, it always depends on the intensity of the sun.

The slow charge on my phone was 27% and in an hour it only charged to 34% in direct sunlight. Cable does not hold well when charging

In direct sunlight the output is 1.4 A so for me it's great.
Three different cables already connected with the charger.
It fulfils its function.
I can't charge through the window (it's a triple pane window so the window is the problem: -( ) So I'm charging on the windowsill.

Solidní kvalita zpracování
Zanedbatelný výkon - měřil jsem výstupní napětí a proud na silnějším USB a nedostal jsem se na více než 5V 0.3A při naprosto ideálních podmínkách. Tyto hodnoty dělají 1.5W takže panel je naprosto k ničemu.
