Those solar chargers that small take a few days to charge, from the integrated solar. I would avoid.
 
^^ Have a 10W renogy foldable, it works well to directly charge phone
(no integrated battery)
 
Most of these Chinese combo solar/battery banks are usually way over rated regarding their capacity/charge time in the sun. I have several of them. One says 20,000 mah and it tested at 8,000 mah(milli amp hours). Days and days to charge since the onboard solar panel may produce 100 mah in direct sun if you are lucky. What you pointed to in your orginal post can be had for less than $20 on ebay shipped for a similar unit. You can charge them using a wall powered USB supply overnight usually and use it as a battery bank and just point and laugh at the solar panel on it. ;)

As suggested, get a 15w foldable panel and you will be happy with that charging your phone or a battery bank. Still takes some time but not days.

Note amp hours, mAH are meaningless without knowing the voltage used for the rating/testing.

The little panels on these gizmos are pretty useless, usually take a few days to refill.

Completely agree just buying portable panels and a decent battery is the way to go, the "all in one" units are at best overpriced, more often an outright scam.
