This 10W panel does indeed produce 10 Watts in full sun.
Produces about 200mA in weak morning sun.

Wires are a bit short. No mounting bracket is included.

There is a blocking diode installed inside the small black cover.

Works well with my small charge controller.

Good value at $18.

The first thing to know about this controller is that it is smart enough to work correctly with lead acid or lithium-ion batteries. Important because the two types of batteries have very different charging algorithms. This controller will be used in a portable setup that is intended to charge lithium ion batteries from a couple of smaller portable solar panels. Having the ability to switch over and charge the lead acid battery in The event it is needed is an extra bonus from my perspective.

The set up and working is clear and simple; the screen is easy to read. Does the job and makes short work of charging my various 13.8 V LiFEPO4 batteries.

How well it will last in regular use is an open question, of course which only time will tell. Are any unexpected negatives this review will be updated.

Alles super danke

We have a condo up in the mountains that we only get to visit a couple months out of the year, but we installed a Blink camera so we can check out the mountain views when we're not there (and to get snow reports when we're on our way there to ski). The summer temps only get to 65-75, and the winters get downright frigid which is murderous on batteries. This panel - so far - eliminates that problem. I just installed it when I was at the condo to ski, and the weather was overcast (it snowed 9 inches yesterday) with virtually no sun. Despite the cloudy conditions the panel charged sufficiently to keep the camera operating when I checked it a few times. Since this lives off a lithium battery, it's hard to say how long it will last - and the battery is encased in the panel, and the panel is sealed so there's no way to replace the battery when it dies. From that standpoint, it'll take about 10 years to figure out whether the cost of this panel outweighs the cost of the batteries ... the benefit for me is that when the batteries die on the condo cam I live 1000 miles away and can't just change the batteries immediately.

The exhaust flang is messed-up
