Don't buy these little kids toys, they are next to useless! Get 50 watts at minimum and thank me later. In other words, pay a little more for something you can actually use. 10 watts peak rated only on the brightest day of the year..... What do ya do with the other 364 days? Get something like these below, something that actually works:

This is for outdoor camera battery. Not enough for car/boat battery.

Not quite, I don't see a USB cable or voltage converter (if there's none built in)

And the 12 battery doesn't have to be in a car. Cameras can. Be connected to such battery
