ALLPOWERSSP033 200W Solar Panel 36V 200 Watts Portable Solar Panel Kit Waterproof IP67 Foldable Solar Charger for Portable Power Station RV Marine Laptops Camping Off-Grid Emergency

I have the Allpowers 140 watt solar panel that is similar in design to this 200 watt panel. the major differences other than output power, is the build quality. The 200 watt panel is more rigid when setup the panel does not sag or droop nearly as much as the 140 watt when using the kick stand legs. Those legs are also different, on this panel the legs are slimmer and they snap off completely if you don't want to use them. I don't think I've used them correctly yet but I did use them while this panel charged my power station and they held fine on my lawn. 2 things to note: first, this is purely a solar panel, it has to be attached to something to be useful, it has no built in charging ports for any USB outputs, it must be connected to a compatible power station, charge controller, or other similar device to be useful. The Second thing to note is that the cables are short, and are unlikely to be long enough to position the panel to catch the best sun and to connect to a device that is not very portable. I use 2 of these along with one 140 watt panel all connected in parallel in a mini "solar farm" I had no issues with this setup. I did use a multi meter to check the output and found that the panel was producing almost exactly the power it was rated to produce, of course, like all solar panels, when there is a load the output power drops so it is unlikely that they will produce 200 watts of power while doing actual work. This rated vs actual usable power is extremely common with solar panels and is not an indication of any mis-leading or false advertising. Solar panels are rated under very specific conditions that are unlikely to happen in real world use, but this rating method makes it easier to compare and shop among different brands and sizes. I don't use panels like these in series because there is more potential to damage the panels when used in series. Also, Allpowers recommends using no more than 3 of these when connecting in parallel. Overall, I like this portable solar panel, it's just a simple portable folding solar panel and it works, I'll likely buy one more in the future to complete my mini solar farm.

The media could not be loaded. I bought three sets of these panels. So, how well did I do?Likes:● the briefcase material is of good quality, washable, and seems durable● the stitching on the handle is very good● the handle may not be top of the line, but it is of decent quality and should last● the panels open and close easily as they have a quality button system● a pouch which closes with Velcro is incorporated on the back for the cable● the cable is MC4● the panels offer water resistance● also included is a MC4 to 5.5x2.1mm cable● also included is a MC4 to Anderson cable● the price point is excellent● performance proved to be excellent during the tests that I ran (see below and watch video)Dislikes (not a big deal especially if incorporating them would increase cost):● no kickstands or alternative system is in place (while I am not a big fan of kickstands since they do not offer anadjustability feature, they do come in handy in many situations)● grommets for hanging the panels are not used● the fabric hanger loops may or may not lastSpecs: VOC = 22.4 V IMP=5.4 ATest Results:October 24, 2020: sky condition was sun with clouds (peek-a-boo) and temperature was 84 degrees, time 11:00-11:30 amPanel #1: 19.3 to 20.9 V, 2.8 to 3.6 APanel #2: 20.8 V, 3.5 APanel #3: 21.8 V, 5.21 ANovember 3, 2020: sky condition was no clouds, temperature was 73 degrees, time was 11:15Panel #1: 19.5 to 19.79 V, 4.95 to 5.33 ANovember 4, 2020: sky condition was partly cloudy, temperature was 77 degrees, time was 11:05 to 11:40 am (this test was video recorded)Panel #1: 17.0 to 19.9 V, 5.27 to 5.63 APanel #2: 19.4 to 19.7 V, 5.38 to 5.47 APanel #3: 19.5 to 19.9, 4.95 to 5.27 APanels #1, #2, #3 connected in series: 59.3 to 59.4 V, 5.19 to 5.22 AThese panels have met my expectations and I am very happy with their quality and performance results. The price point was the first feature that put them on my radar and research list. Their quality and performance is what is keeping them in my emergency preparedness arsenal. I do not have any doubts that they will perform well when charging my power stations.
