Fortunately the battery pack charges through a micro-USB port accessible …,
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.
works great, mounted usb down and so far no problems …,
5W panel. Nice construction, fabricated output power.,
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 🙂
