Is that any good? I kinda don't want to pay 30 for it though.

You can get a power bank with a panel on it for cheaper, but it's going to take forever to charge

Those banks don't really charge from solar.. they just sort of top off or maintain. The panels are too small and the battery ends up taking damage from the heat of bring in the sun. You're better off using a large solar charger like this wired to a battery pack that is stored under something to protect it from the sun's heat but with some airflow to dissipate charging heat on the battery itself.

Sale price is dead; it's gone up to $99.99.

Anyone interested in this (for when it goes on sale), click on that video overview among the thumbnail pictures on the Amazon product page. It's refreshingly honest and frank. This "20 watt" panel is actually only a 16 watt panel according to the specifications listed in the included owner's manual. And according to the guy who produced that video, it only produces about 8 measured watts on a very sunny day.

Judging from his accent, he sounds like he's in the UK and did his most favorable testing on 9/19/15. At lower latitudes and closer to the summer solstice, you might crack 10 watts under ideal conditions.

But this is in no way a 20 watt panel.

I just got it and the manual says 20W.

The video reviewer has the 16W version, as indicated by his narration at the beginning and the Amazon page he showed at the end of the video.

This is the 16W version.

Yeah, I wouldn't count on 20W being the "norm". 20W is probably just what the maximum capability of the panel under ideal conditions.

Thank you for that clarification. That video was a poor choice to include in that Amazon product page then. Have you tried using your Sauoki charger yet? I have a 14 watt panel, but it's the older, less efficient panel technology and is also about 30% larger/heavier. I don't have a watt meter to measure it's actual output in real world conditions but it's been a trooper recharging cellphones while camping.

The confusion is probably due to Amazon or the vendor merging and separating the listings of the 16W and 20W models.

I haven't had a chance to really try it since it's cloudy. But I do see the red LED light does light up under some light. I set it up at home with a battery pack connected next to a window in the morning, and it wasn't able to start charging in such a poor condition.


There are some video reviews I found.

Thanks you ubermoxi. The price is not budging for $99.99 for this.

Settled for this one from ebay. http://www.ebay.com/itm/5V-7W-Sol...2042818227 as this was close to original price point.

The 20W version has 3 panels, so it's bigger than the 14W version. $40 seems to be the norm for 14W. Another thing to look for is the "Sunpower" panel, seems like all the newer version has this type of panel (higher efficiency).

Look at the comparison chart of the Anker version, it shows the difference between the new and old version of the panels:
https://www.amazon.com/Anker-2-Port-Charger-PowerPort-iPhone/dp/B012YUJJM8/ref=sr_1_7?ie=UTF8&qid=14... [amazon.com]

I haven't done much with mine. Just lay it by the window and try to charge a battery pack. It does show it's charging once the sun shows up. But it's very slow, as expected. Smilie

The cheapest 20W I can find is $45. That made the $30 Suaoki looks really good. They all pretty much look alike, so I am thinking they are basically the same thing.
