   This product works for the very specific purpose I had in mind for it. This review does not get into verification of the panel’s technical specs as some others have, but I have no reason to question the other reviewers’ findings. But again, these panels do what I want, cheaply, and that is output a relatively low current at nominal 5V.

   I use these panels to keep a constant charge on a pair of Lorex wireless outdoor security cameras. The Lorex cameras use a detachable, rechargeable battery pack; it’s weather sealed, and rated to last up to several weeks between charges, but in practice my batteries were dying after a week or so, and climbing onto a ladder to detach, take inside to charge, then reinsert so frequently was not sustainable. Fortunately the battery pack charges through a micro-USB port accessible from the outside of the pack while in use. Charging like this works, even if it compromises the weather seal. So my big question was, can this solar panel keep up the charge? And after a month of flawless use, I say YES. My cameras have kept near full charge since I put these chargers to them.

   A few more details:
   – On unboxing, I thought the panels might have been an outright hoax since they don’t have the normal appearance of a metallic solar cell. But the built in indicator LED lit right up when I waved them into the sun, and obviously, they are working for my cameras.
   – The panel is a stiff multi-ply plastic that seems completely sealed, except at the USB 5V output port. My first reaction aside, it seems well crafted and durable, roughly the size of a notebook sheet. Just don’t expect to fold it away somewhere; it is rigid.
   – I don’t know what they’re outputting, but I have mounted them hanging vertically against the wall of my house, with the panel’s USB output port facing down. One catches direct morning sunlight, and the other catches direct afternoon sunlight, but they seem to work on indirect ambient bluesky lighting also.
   – I haven’t sealed the ports in any way other than facing them down so they don’t catch rain. Through a few rains, high winds, and even some snow, I haven’t had any problems with shorting or failure at either end of the basic USB cords I connected them to the cameras with. I’d intended to go back and seal them with some silicone after a test period, but I might just let it ride to see how it plays out.

   used this to power/charge remote driveway sensors in security system,works great ,mounted usb down and so far no problems with water, i did spray a coat of flexseal over usb connections once affixed ,may not put out the advertised 10 watts but, best output for the price ive found in a semi outdoor panel, how it stands the test of time outdoors is yet to be seen , but will charge 4 bank of 18650s powerpack in 5-6 hrs in good sun,does well in low light also and maintains my security driveway sensors worry free GB

   The panel is nicely made (though the USB port cover is fragile), but it is a 5W panel not 10W as advertised, hence the other negative reviews and my low rating. A normal charge these days is at least 1000mA. I was not able to get more than 440mA in direct sun. It works, it’s just not a 10W panel and will typically give you a very slow charge.
   Why does this matter? A standard 1000mA charge @ 5V is 5W. If a panel is rated 5W then it needs perfect weather/time/position to achieve this. A 10W panel could much more easily supply the 5W output you are looking for under less than ideal conditions. This is not a 10W panel …so probably not what you’re looking for if you want a decent charge.

   For those who care, I believe these are higher than average output cells (Sunpower?) in the 22% efficiency range (no front tabbing wires or visible silicon structure). 10 series cells should yield close to 6V which is regulated down to 5V. The individual cell size is only 19mmx125mm, though, so at 0.00022mW/mm^2 (22% efficient cell, 1 Sun irradiance), ~520mW max per cell. 10x that for the 10 cells and the max output is about 5.2W. Encapsulation and buck regulator losses taken off of that …and you’re very lucky to come away with 5W output (1000mA @ 5V) even in maximum sun. The description says 1200mA USB output which is not possible, unless, as another reviewer mentioned, you were on the surface of the sun 🙂
