Very confusing: Title description says 140Watts. Panel received is 120Watts. Solid output at full sun is about 90Watts.

Very good for the price, bought from warehouse "excellent condition" and it did come in excellent like new condition.Shipping was as fast - got it next dayAll the MC4 connectors are useful, especially the MC4 to Anderson to my solar battery bank.Initial testing on early spring day 11am with clear direct sun and 10C temp:My MPPT solar bank is getting 102watts input.Pretty good for these conditions and meets my expectation that this will at least get 120watts max input to my battery when camping in the summer!All the charging ports right from the panel is a huge bonus, very nice touch, and will sure to come in handy one day in a pinch for charging a laptop etc.Ordered another one.

a pleno sol de 140 w alcanza 100 razonable bien construido y practico

Overall the solar can generate power to charge battery banks, and other camping electronics. If you're looking to power your laptop keep reading, it's possible but requires extra adapter.Product is not exactly as described 140watt. DC port can only generate enough electricity to function if you have completely clear skies.If you're looking to have the best charging capabilities you'll want to use the USB-C port as it has fast charge capability, and if you purchase an adapter to convert USB-C into a DC port it works much better.

This set of panels work perfectly right out of the box I set them up in the sun and the did 120 watts. They are going to work out great! Thanks for the great service Allpowers.

This is a good solar panel. Is 140watts. I tested it in winter in full sun. I got 110watts which is pretty good. Is well built, sturdy, feels worth more than I paid and cheaper than anker, ecoflow and bluetti panels. Win. Solid. Even with my dog blocking half the panel soaking in the sun( huskey) it still made 70watts. I'll take it.

The more you know about how solar panels work, the better you can decide which one to buy. Solar panel output power is measured under very controlled conditions, conditions which are unlikely to happen in the real world. Solar panels also tend to produce more power when they are cold vs when they are hot, and they produce more power when they are not under load. All this is to say that when I got this panel at home, and checked it with my multi meter it produces exactly the amount of power that I expected. It produced so much more power than my power station could handle that it tripped the over power protection. once it warmed up a bit the power dropped and I was able to charge my power station without any problems. The next thing I discovered, the charge controller you connect your panel too is really the device that determines how much power you are going to get out of your panel. I purchased this panel in hopes that I could get a little over a 100 watts of reliable power into my power station, however I quickly realized that the power stations charge controller just wasn't going to let that happen. I initially thought the problem was with the solar panel, but later realized it wasn't even a "problem" it's just the way the power station ( a small portable station ) works. I say all this to help explain my rating, I like this panel, it works well, it's light weight it has pretty good build quality and it has the ability to charge a phone or similar devise because it has a built in charge controller (their words, not mine) Like many other reviewers have mentioned, the light weight build means that the panel will tend to droop or sag when you use it with the built in kick stands, this is of course not a problem if the panel is just lying flat on the ground or hanging using the sturdy grommets. The bottom line is the panel works fine. As I understand solar panels more and more, I understand that you can't expect to get a stable reliable 140 watts out of a 140 watt solar panel, you need to over size the solar panel by some amount, or buy multiple panels and connect them in parallel or series (if the panel is rated for either of these options) to get a reliable amount of power. Also like I am beginning to realize, you might see better overall results if you pair your solar panels with a quality charge controller, one or two lithium batteries and a good pure sine wave inverter, instead of or in support of using a portable power station, of course this depends upon your needs, the space you have available and your situation. But back to my rating, the droop and sag when using the kick stands is why I would, if I could, rate this panel at 4.5 stars, but because it does work and works as expected I'll round that rating up to 5 rather than down to 4.

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.
