ALLPOWERS SP027 100W Foldable Solar Panel,23% Efficient IP67 Waterproof for Power Station, Camping, RV&Home Use, Compact Portable Design

Recommended I don't know about the life span but definitely worth the price

I wanted this type of product for energy solutions and I surprised after finding on Amazon. Very useful product to spend the money. Thanks ALLPOWER

Generates 60% solar harvest due to polycarbonate pv panel.

I've got three of these. Excellent quality feels very sturdy. Generated 90w during summer with my allpowers s700.

I had 2 sets of these plugged into my portable power bank. I averaged just over 50% of rated output (104-115W) of an advertised 200W. I bought these on a sale to try them out. For the low price I was going to buy a couple more and the cost per watt was still reasonable, however with the price more then doubling I will look for an alternative.

It gives 4amps late afternoon. I tested today over lunch time and it gave 6amps of charge. Very good.

While I like the size and weight of this portable solar panel, and I appreciate the MC4 connectors, I am not happy with the product. I have tried several methods to get more than 34 to 36 watts from it, and have been unsuccessful. I have used two different goal zero Yeti 400 units with below 50% charge in them. Neither can get more than 34 watts from this panel. (They routinely charge off a rooftop mounted 100w panel at over 70 watts so I know how they perform with other 100 watt panels.) I have also tried a separate automotive charge controller on a slightly discharged car battery, and was only able to draw 2.5A at 14.3V, so again not quite 35 watts. All of this testing was done on a clear day, low humidity, at about 3000ft elevation over the course of a month when conditions allowed. So I am not really happy with this portable solar panel. Maybe only one panel is working? Maybe the panels are of low quality? I don't know, but I suggest you try something else. UPDATE AUGUST 2024 So get this! Allpowers contacted me. The nice representative asked me to perform some basic tests (simmilar to what I had done previously which led me to my previous review). After two or three emails to verify the test results, I was asked to render the defective panel useless my cutting the MC4 output cords, and in return, they would send me a new 100w unit. About a week later, I did indeed receive a new replacement panel. When testing the new panel to charge a mostly depleted Yeti 400, I was able to get nearly 80 watts on output on a hot summer day. That's totally acceptable for a folding panel that is this lightweight and portable. Thanks Allpowers!

I bought this portable, foldable, light weight panel with some fear. So many times things are priced frugally for a reason and that reason is poor workmanship and with lower value materials and the product doesn't do as advertised. I was pleasantly surprised upon receiving this panel. -Had two stands, one for each panel. -had the connectors I needed -light weight -small -easy to fold MOST IMPORTANTLY: It gave me between 43 Watts(clouds, not optimal setting) and 105 Watts(full sun at noon directly on panel) on my Bluetti 150!!!! I was worried that the voltage produced by this panel wouldn't be high enough as this Bluetti unit requires Open Circuit Volate of 16 but it worked marvelously. Success! I was so excited when I saw those numbers jump from 43 upwards. It gave me consistently 86 watts over a longer period of time. This is my first time using solar and I'm still awestruck at technology. The sun rays....being captured by this panel....and storing it in this cool box.... and I can then use that box to run all sorts of electrical devices....and it costs me nothing after the initial investment.......what a world... I ordered another panel and might even get a third. Edit: Bought a second panel and it works just as good as the first! I put it in series with the first and received double the watttage as hoped for. It hit up to 205 Watts! The average was about 182 watts during peak sunlight. I'm very happy with both panels. So simple to put in series as well.

So, bought it this summer while on discount. Big mistake, waste of money. It's clumsy as hek, the small "legs" are weak, the material at the bottom is already falling apart and it touched the floor of my patio like 3times The panels are binding under their own weights Odd to open and manipulate So basically, that was a huge mistake from my side and should have try it when I could still send it back. Most conditions I tried it with, no current output at all into my ecoflow. In full exposure, yes it will charge, with perfect-esque conditions. You're better off with the normal though built ones, which are much more portable and durable. This product, in my experience so far is pretty disappointing. I wouldn't recomand it.

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 an adjustability 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 last Specs: VOC = 22.4 V IMP=5.4 A Test Results: October 24, 2020: sky condition was sun with clouds (peek-a-boo) and temperature was 84 degrees, time 11:00-11:30 am Panel #1: 19.3 to 20.9 V, 2.8 to 3.6 A Panel #2: 20.8 V, 3.5 A Panel #3: 21.8 V, 5.21 A November 3, 2020: sky condition was no clouds, temperature was 73 degrees, time was 11:15 Panel #1: 19.5 to 19.79 V, 4.95 to 5.33 A November 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 A Panel #2: 19.4 to 19.7 V, 5.38 to 5.47 A Panel #3: 19.5 to 19.9, 4.95 to 5.27 A Panels #1, #2, #3 connected in series: 59.3 to 59.4 V, 5.19 to 5.22 A These 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.

I purchased this panel to complement the same-brand ALLPOWERS 300W Power Station battery unit. (purchased separately). I'm very satisfied with it. It's exactly as described, seems well-made and durable, easy to use and charges my battery unit quite efficiently and effectively. In full direct sunlight, it was easily putting 70-80W into my battery and only took a cpl hours to refill it completely. I was pleasantly surprised to see it keep pumping power (although reduced) when the sun wasn't hitting it directly. It has a couple of handy pop-out legs to keep it tilted at the right angle to the sun, and well as an attached pouch that holds the MC4 panel cables and a couple different types of adaptor cables to connect it to your power unit or device. Order fulfillment was quick and easy and it arrived in 2 days, well-packed for the trip. I'd definitely recommend this model if the power output meets your needs.
