I wish I could give this 4.5 stars because this is a great value that does what it is supposed to, but isn't as universal as some may think. For the record, this review is as much information sharing as anything.2024 UPDATE: More details on watts producedTL;DR: Works with Bluetti power station but you need to buy an XT60 adaptor or use the cables provided with the power station if you have them. Panels are wired in parallel which is good for partial shade. Was able to get 60W in less than ideal situation so you can charge a 500Wh power station throughout the day. Best output watts I have seen is ~80W Good value, but not flawless.I bought this for $125 to use with my Bluetti EB55. I didn't want to pay $500 for 200W panels from the manufacturer, but wanted a bit more than what the knock off 100W panels offered. This was a good compromise. Despite having lots of different adaptors in the box, I had to purchase an Anderson to XT60 adaptor to get this to work on my unit. Allpowers provides a barrel plug that fits the input for the Bluetti, but that particular jack requires 20V to work and this panel wasn't able to provide it. By going with the Anderson to XT60 (I originally thought they were the same thing, but they are not), I was able to get things working. (Edit to add: I later realized my power station came with the cables needed.)Two important details about these panels that are worth noting: crystalline structure and parallel vs series wiring.First, these panels use polycrystalline silicon instead of monocrystalline like some of the more expensive models. Essentially it is a bunch of small pieces instead of one big one. People talk about mono being more efficient, but in my experience that has more to do with surface area required than with anything else. Since poly is cheaper, if you want to save a few bucks you can use it, but you will need slightly larger panels to get the same wattage. But if you are purchasing based on output and price, it doesn't matter.The second item is related to how the individual panels are wired -- either in series or parallel. Without getting too technical, if a multi panel unit like this one is wired in series, then if one panel is partially 50% shaded then the overall output will be 50% less even if the other panels are in the full sun. However, if say a 4 panel design is wired in parallel, and one panel is 50% shaded, your output power will only drop by about 12.5% if all the others are in full sun. These panels are wired in parallel which is great and something I was originally worried about.Now let's talk about output. It is winter here as I am reviewing this. The sun never gets very high in the sky, it is hazy, the days are short, and since I live in the woods, everything has at least some shade from leafless branches. It is close to worse case scenario for a "sunny day" I will encounter. In these circumstances I am about 60W just setting things up quickly and not being too particular about alignment.60W out of panels advertised for 140W doesn't sound very good, but it was much better than I was expecting given the circumstances. Since the EB55 is 537Wh unit, I know that even in less than ideal situations, this will be enough to charge it over the course of a day.UPDATE: Running these in full sun near the solstice at mid day, I was getting outputs of around 75-85 watts, so that is what I am using for best case scenario.Given that ~500Wh power stations cost $500 on their own, I was not eager to basically double that amount to add solar functionality. I am very pleased to be able to recharge every day while spending less than $150.Since this is technically a review, let me drop a few other quick thoughts on the unit.- There are lots of adaptors you can use that come with the panel, but don't assume that just because it fits it will meet the needs of your device.- The alligator clips they include are basically useless since it can be dangerous to try and charge a battery without a power control unit.- The USB controller is nice and having it work with USB-A and USB-C is a perk. Can't really think of a situation where I would bring this but not my Bluetti, but still a good perk.- The pouch is nice to have to keep all the wires.- I like that if I decide I do need more power, I can buy another unit and wire it together with this one.- It is a bit heavier and bigger than expected, but not burdensome.Final verdict: Great value if you want solar charging and can work around the limitations.

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 2024So 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!

These panels are a little flimsy, but that helps keep the weight down I suppose. Output was impressive. Easy to store for bringing on camping adventures. Keep’s all my electronics, batteries and portable fridge topped off

This solar panel is working beautiful, it built in 10,000 power bank, it only take 5 to 6 hours to get 100% fully charge, of course you have to put this solar panel toward the sun direction to get fully charge, my conclusion is this solar panel is working like it said, some other solar panel say it work but not really charge fast enough like this solar panel, I would recommend this solar panel 100%.

I purchased the 140W Allpowers solar panel about a year ago, and it worked fine for my needs at the time: camping, re-charging portable generators, cell phone, laptop, etc. I use a powered telescope, and with it the portable generators and laptop. Suffice it to say that the 140W solar panel was adequate. HOWEVER, it is about a year later, and I needed to buy a larger battery pack or generator I could run at night while camping. Hence, I needed more power to recharge said generator/battery pack Seeking affordability, I once again bought the Allpowers 140W solar panel. And then . . . it began. I could see on my batter pack, a Generac GB1000, that my input wattage from a single 140W solar panel was 40W, varying and fluctuating, but also increasing as the day progressed. Prior to connecting the solar panel(s), I measured voltages of each, one panel at about 21VDC, and the other at 20.3VDC. I connected them in series, and measured 38VDC at one point, and then 42VDC at another. I'll chalk this up to the saturation of the solar cells as the day progresses. But to charge the Generac, the specs on the Generac say that the max voltage to charge the Generac is 28VDC. Therefore, charging with the solar panels in series is a no-go. Hence, I had to connect them in parallel, in which case, I measured voltage at 20.2VDC. Connected to the Generac in parallel, the input power indication is 67W, going as high as 77W, but generally holding at 67W. So that's 2 x 140W solar panels in parallel measuring at 67W input to the Generac. Total power, however, with 2 x 140W solar panels should be 280W. However, reading the specs on Amazon for the Allpowers 140W solar panel, they indicate 140W Peak Power. So taking 140W peak power and dividing that by the square root of 2 gives me about 98.99W. So, 67W compared to 98.99 is 67% of that power OR: let's take 67W and change that to a peak value: 67W x the square root of 2= 94.75W. So 94.75W x (100/280) = 33.84% of the rated power with 2 x 140W panels in parallel. Now let's take the 40W value from a single panel, and change that to a peak value: 40W x the square root of 2= 56.57W. So, 56.57 x (100/140)= 40.4% of the rated power of a single panel.Whether we use percentages, or just what we see in the measurement of power, the 140W Allpowers solar panel is not producing 140W peak power. Indeed, there are variables to consider, such as placement of the panels with relation to the sun. Maybe the lead engineer in research and development at Allpowers was having a bad day and happened to be using a broken calculator. Maybe quality assurance at Allpowers doesn't have a strict testing protocol where the outputs are measured. I don't know what the test conditions were in designing or how the manufacturer arrived at 140W peak power, which by the way, is an easy defense for them if one doesn't know how to arrive at these numbers using the right calculations. Just based on my voltage measurements, power indications, and calculations, the Allpowers 140W solar panel is NOT as advertised, and hasn't come close to producing the rated peak power. Take what you will from it, be your best self, do you, and make the decision that works for you. As for me, even if a $1k solar panel produces the advertised rated output, I couldn't afford it anyway. This particular solar panel has been adequate to my needs, albeit OVERRATED and with that, probably OVERPRICED. And in case you're wondering, I have a background as an electronics test technician for aerospace, a background as a robotics technician, a former electronic technician in animation and production, and I am currently an electrical test technician in power utilities (just in case Allpowers has a need to know).

2021 AllPowers 120 watt Solar PanelI already have an AllPowers 372Wh Power Station Generator. Which works great. I have used it to power lights and fans during a power outage. Also used it to power Christmas lights on my pontoon boat this year. The Power Station is easy to use, well built and even supports Bluetooth connectivity through an app on my iPhone. I compared many brands before choosing Allpowers. In the end AllPowers offered the most features, quality and value for the price. Very glad I made the Allpowers choice and highly recommended it. I am an AllPowers fan.Anytime I have contacted AllPowers support they have been quick to respond, knowledgeable about their products and very willing to engage on resolving my issues.Now I am trying the new AllPowers 120 watt Solar Panel, to charge my AllPowers power station generator. This panel is capable of charging any Brand of generator/power station or other project needing solar power; As it comes with a wide variety of connectors and adapters. My AP power station can use AC wall power, a DC 5.5 x 2.1mm barrel plug or an Anderson connector to charge. This panel comes with both DC5521 and Anderson connected, as well as adapters for many other needs.It’s size and weight is what surprised me the most. At 22 x 14.2 x 2 when folded, it is just two notebook paper pages tall by a little more than one sheet of notebook paper (landscape) wide. When fully open it is 22 x 60 inches, much smaller than similar wattage panels. I believe this is because this newer panel is more solar efficient than older style panels @ (21%). Ultimately this means this panel has a faster charge time, is lighter weight and is smaller size than similar older panels on the market.It comes with a built in charge controller that manages the various voltage and amperage power out of the panel. For example the MP4 solar connector provides 21v at 20A, DC ports provide 12v at 10amps, USB ports provide 5v at 2.4amps and DC 18v at 3amps for a laptop. You can also chain two of theses panels together to get more amperage for even more power and faster charging times. All right out of the box.Overall this is an impressive foldable solar panel with all of the features and adapters you may need, faster charge times, better solar efficiency, lighter weight and smaller size than comparable panels. I continue to be amazed at the AllPowers products. The quality and features they offer are first rate and are offered at a very reasonable price point.

I have had seven years of DIY solar panels (hard, flexible, foldable [60-300watts each]) and seen many claims of watts but typically cautious when listing doesn't specify amp and volts for the PV panel output. I saw actual 18.7 volts so that part was correct as 18 was listed but the amps produced were disappointing and 1/3 less than expected given the brightness of the day. I'll explain:Taking my year old 4 x120 (total 480) watts foldable panels with kickstands I got 246 watts (51%). Very typical for my latitude. Then plugged in just 4x200 (800) watt panels using same wiring, same location +/- 2 feet same 1000 watt 10-32amp MPPT inverter just these panels were different at same angle and got 268 watts (34%). I then tried another exact spare MPPT inverter switching back and forth and got same results plus/minus 1%. Tried a few tests on the individual panel and again at my location and degree of brightness and these 200 watts produced no better than my older 120w (half fold). These four fold PV panels take up a longer run and with the short attached MC4 cables and acclimated kickstands make it difficult to connect in series without buying extension cables. Foolishly I purchased 6 of these from Amazon Warehouse thinking I was getting a good deal on cost per generated watt. Yet not one of the 6 performed any differently when tested individually. or together. Had I paid full price these would have been boxed up and on their way back to Amazon.In fairness this unit is very typical of some of the panels I've seen and purchased in past years promising high wattage but failing to clearly list specifications of PV output amps, volts and conversion efficiencies. I'll hopefully never purchase any panel again not doing the math of max (amps * volts = watts) then looking up the suggested conversion efficiency rating and surface layers coating and reading reviews. While more rigid then the 300w I purchased and broke cells and wires at the folds after a year. I'd be cautious/careful unfolding these for camping or everyday deployment vs the rigid 120's I own feel more solid. These being reviewed cost me more money, weigh more, take up more space, no USB connections or regulator just a straight MC4 connector, feel flimsy, ...... then I've purchased before that turned out to be my most disappointing with poor performance: a lesson learned.

It's very very large so even though it's not that heavy it very awkward to carry. But it works great! In a state by the Great lakes, mid May laying flat on the ground it got 563 watts! It was regularly over 500watts. I would definitely say it's worth it, especially if you have a power station that has 20amp 60volt limits like my bluetti elite 200. I got this for less that $340 so just wait for a sale! I love that I don't have to track the sun to get good power!

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 foldMOST 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.

This foldable solar panel should prove very valuable in emergency situations. The build quality seems fairly decent, though I would want to take extreme care using it during any amount of rainfall. I seriously doubt any claims of it being waterproof - the USB ports don't even have covers.I live in southern Ontario and today on June 3 I put this panel outside and connected it via USB-C to an Iniu 27,000 mAh battery pack that's capable of charging at up to 100 watts. The battery pack has a built-in display which shows how many watts it's receiving and I checked it at various times of the day to get a rough idea of the solar panel's performance.- Laid flat around 9 AM, overcast or in shade: 1-2 watts- Laid flat around noon with full sun: 48-50 watts- Laid flat at 6 PM with full sun: 12-13 watts50 watts of real-world output on a claimed 60 watt panel is pretty darn good. Looking at other popular solar panels on Amazon you'd expect this one to peak at 25-30 watts at best, and yet it's giving me 50 without even aiming it directly at the sun! Unfortunately I couldn't take any photos, the display doesn't show properly on a camera.By the end of the day I'd fully charged the 27,000 mAh (99.9 watt-hour) battery pack. This is despite the battery having apparently overheated and paused charging for some period of time as a result of being outside in direct sunlight while also charging at ~50 watts (maybe more?). That's tons of power for an entire family's worth of portable electronic devices as well as an emergency radio if they're all used with some moderation.The 1-2 watts it delivers when even while shade or overcast conditions should be enough to keep a single cellphone charged pretty much indefinitely as long as it's in a battery-saving mode and only used sparingly. As a safety precaution I will only be using the panel to charge battery packs, not actual devices. Also, I checked and the panels seem to be wired in series, so output will drop by half or more if any of the individual panels are blocked.Overall this seems like great product in my opinion and I highly recommend it. The same company also has an (allegedly) higher-wattage folding unit available but I read some troubling reviews on it and it's unclear if it has a USB-C charging port - not to mention, the most you'll see anyone claim to have got from it is ALSO ~50 watts. Might as well go for this simpler 6-panel version, there's fewer potential points of failure and it definitely has a USB-C port.

Finally used this recently during 3 day power outage with Ecoflow Delta Pro and it worked flawlessly. Overcast day, but was getting around 240-280 from what I saw. I also had an EF 200w panel out and that one was drawing around 130-140. If worth noting, I had them both laying flat on the ground. All around, what I expected and it kept our DP with juice until power returned.

I bought a panel and loved it.. so bought another for my friend..it arrived in Nov.. but they never used it until July.. and it proved defective.so obviously Amazon wouldn't take it back so I reached out to the seller.they had me go through various scenarios to prove the panel was defective and send them video of my efforts.they didn't ask anything ridiculous to prove... just common sense actions to show the panel was not charging.then they told me they would send me a new panel.. and 5 business days later it was here.their customer service is outstanding and thorough. and I love their solar panels.I would recommend their panels to anyone.

Works as advertised
