100W Portable Foldable Solar Panel Kit for 12V Battery Charging | Folds to 19 x 26 in and Weighs 5.3 lb; Includes Controller and Dual USB; for 12V Batteries, Power Stations and Camping.

This kit can charge a lifepo4 battery. Maximum charge current is coming from this cheap pwm charge controller, it's only at around 14.6 volts max voltage from this controller with this solar panel. Which is enought to charge a 12v lifepo4 battery at 14.4 volts charging. The only trick to charge a lifepo4 battery more quickly, is to have full sun day on solar panels. Best to invest in a mppt controller charger, but not totally necessary for a small solar panel setup like this. 14.4 volts in full sunlight on this solar panel to charge your lifepo4 battery fully. Make sure solar panel face is facing sun at 90 degrees to sun for best voltage. These solar panels seem to work, but they are fragile. Do not bend them too much, I heard one making a slight crackling sound when bending slightly. Good to have or make a solar stand that supports this solar panel well so it doesn't bend much. Like make a solar stand out of pvc pipe and carriage bolts to make a folding frame stand. Nice to have this light weight portable solar panel. Does charge a 12v lifepo4 battery 50 ah pretty quickly. But better to buy another solar panel to get more juice to battery for when you have loads on battery, and for charging, topping off your battery much faster. Too bad that all solar panels are only about 23 percent efficient or less. Can you imagine if solar was 100 percent efficient ? You could then run the whole World off of pure sunlight !!! Plenty of power comes from solar if We could get much more efficient panels, controllers and batteries. We need about 50 percent more efficient solar for it to really take off, and for a forever energy source. Solar panels used in space by NASA etc. like on all satellites, work better in the coldness of space, if you chill a solar panel down in temperature you can get much higher charge current. Much More effeciency from freezing temps, on a solar panel.

Since they arrived, I've been quite cautious with my panels, given the mixed reviews, reports of very little power delivery (both initially and degrading over time). I suspected that the people reporting decreased power production over time may be over-bending and over-flexing their panels, damaging them over time. I've been using my panels for a few weeks now, and so far, my experience has been very pleasant! I also have made sure not to bend or flex them, avoiding leaning them against anything (esp at a harsh angle). So, I've really just placed them on top of my van. I've been very happy with the power delivery. I have been sampling it over different days in different conditions: - Midday, light clouds: 128W-149W @ 16-17V, giving 8-9A. (see images of screenshot for example @ 146.2W, and the partly cloudy sky) - Early morning, full sun: 90W @ 18V, giving 5A - Midmorning, very cloudy: 40-65W @ 16-17V, giving 2.5-3.5A - Summer evening, cloudy, tree coverage: 20-40W @ 16-17V, giving 1-2.5A So, I was shocked. I've seen it get up to 160ish Watts, and never expected to see more than 75% power (150W). So I was happy with that. And I'm also surprised that even with pretty heavy clouds, I was pulling in roughly 3A. Since I'm mainly planning to run my laptop and phones, (and possibly a small fridge), even this 3A is enough power for me if I let the panels run all day. One other location I was curious about was placing panels on my dashboard. I want to try exposing just a single panel, hoping that it can fit on my dash without shadow. 2 unknowns: I don't know how much my windshield will block the light, and I don't know if 1 panel can pull 1/4 of the full power potential. My understanding is the panels are wired in parallel, which is excellent, because they're essentially operating independently, or additively. (If they were wired in series, that would mean whichever panel had the lowest power, that would be the max power possible from every panel.) Still, in practice, I think I'm getting less than 1/4 power from the single panel. My thought is that the full panel covers so much ground, it's more likely that at least 1 panel will receive good light. However, the smaller footprint of the small panel will only pull 1/4 power when it's getting full sun. In other words, in full sun, I suspect the single panel will pull 1/4 of the 4 panels. But with any clouds, having all 4 panels present will actually help maximize power. I have a LiFePo4 battery, so the included charger won't work. Still, I'm happy to have this junky little charger in case I want to drag the panels out to the beach, providing USB power, or for emergencies to trickle power into my car battery. It would be nice to be able to lean these panels against a wall, or the side of my car. I'm just too nervous that I'll damage them with flexing. I'm thinking about creating something out of some old tent poles, but haven't yet landed on a design that I'm excited enough to build out. The other day, I came outside to find the panels had blown off my van and were just laying in the lawn. They seem to be still functioning fine. So, I'm happy that the panels are sturdy enough to withstand a 7 foot fall onto grass. I also need some basic solution to keep 'em strapped down, because I don't want a $200 kite. In terms of the quality, I'm pretty happy with the fabric itself, the quality of the handles, etc. The little metal rings seem pretty flimsy, but I can work with that. And some of the stitching is coming undone, leaving some dangling threads around. Again, I can mend that and deal with it. Overall, with a couple underwhelming features, I'm more than happy with the power output. Nothing in this price ranges is even close, and I can't even find another panel offer this kind of wattage.

Final update, July 2024. After having (now a total of three) of these Dokio panels, I need to update my review. I won't change the stars, but really only think they are a 3 star product now. Two issues. The first, and most important, is I'm finding the SAE connectors coming off the panels expand and soften when they get really hot (90 degree day in sunshine), and lose connection. They also pull apart super easily, and you may not immediately notice you've lost that connection. Second issue with the SAE (and XT60) are they are not standard for solar. Virtually every other brand out there uses MC4 connectors. Neither the SAE nor the XT60 allow you to connect panels in series (which you may well want to do if you are using any other controller than the cheap one provided). I ended up cutting the SAE connectors off and wiring directly to the XT60 from the panel, then building an adapter from that to MC4. Second major reason for "downgrading" my review is the amount of power they produce (or don't). I have two "brand x" panels each rated at 200 watts, and they provide about the same amount of power as the three Dokio 220 watt panels (in both cases,panels connected in series - so three Dokios versus two "brand x" and those combinations provide roughly the same power). I'm going to keep the Dokios, as I already have them, and they are lighter weight and more portable than "brand x", so are easy to haul for portable use where I may not need more than what one panel provides. They do work, just not as well as some of the competition. Another update. I do like the portability. Since writing the below review, I can report the absolute highest production I've seen from the panel was about 140 watts. However, this panel is priced comparable to a number of 100 watt panels (and produces more than 100), so I guess it is a reasonable value in that regard. I decided to order a second one of theses so as to have a pair of matching units that I can parallel for higher power, and the second unit arrived today. It works comparable to the first unit, and in parallel they do produce twice the power as either by itself. Today was an overcast day without shadow, so power output was quite low - about 20 to 30 watts per panel. With both in parallel I was getting 40 to 60 watts with full overcast and substantially more with partial clearing (but not direct sunlight). Usable if not ideal, but decent for the portability. Product as described, very brief setup and test late afternoon appears to work well. But one major issue, the XT60 connector for the load connection to the charge controller is not the correct connector. Am ordering correct connector, but that added $10 to overall cost. I had already cut some of the wires to put power pole connectors on, so was past point of returning. Unnecessary hassle if they checked product before shipping this would not have happened. Today I received the correct connector (ordered separately from different vendor), and hooked everything up. On the brightest, sunniest, day of the year (summer solstace), in direct sunlight, I'm pulling an absolute maximum of 8.8 amps @ 12.7 volts, or about 112 watts (from a panel rated at 220 watts). While I am neither surprised, nor disappointed (this is about what I was expecting and hoping for), it is clearly not what the panel is rated/advertised at. This is better than what I was getting from a less expensive, lower quality, panel bought elsewhere. Note, I am at 47.7° N Latitude (WA State), so solar is less effective than say Arizona or Texas. Getting about 1/2 of advertised power seems to be fairly consistent reporting from a variety of users. I have not checked performance in shade or any other condition than direct sunlight - obviously it will be less effective but I don't know how much so.

The Dokio stands are not so great, but the folding solar panel produced more power than I expected. This thing folds up and is can be carried by one person. It is great for keeping the RV battery topped off and as a supplemental input to my Bluetti Apex 300. These only produce 300 Watts under ideal conditions. However, compared to my 400 Watt rigid panels, these actually made more power under the same conditions.

This is the second Dokio foldable solar panel I've ordered, the first being a 160W 4 panel folding I bought in March 2024. I wanted a separate 100W range portable panel to use with a stand-alone 50AH LiPo battery I use with our Starlink Mini when camping in remote areas. The 100W Dokio does not disappoint me at all. The 50AH Lipo was discharged to about 60% last week, and I am using the 100W Dokio to recharge it . I set it up in early morning sun, tilted at 90 degree, and I am getting 22V out at the panel leads, and 13.7V at the Dokio controller for the solar panel, with 6.0A charging current to the battery. That equals 82.2 watts output from the morning sun (82% efficiency) so I am very pleased again with the Dokio design and quality. My only beef would be the controller menu access and selection is extremely difficult to navigate.

Ok well after thinking portable are the way to go because I want to park in the shade! & not drill holes in my roof. Well folks the massive advantage to doing just that is when your DRIVING! U R in the sun most of the day here in the west, but being stubborn I went with the largest foldable panels available, 300 watt 4 sheet fold. It is easy to carry easy to set up PWM works ok love the simple alligator hook up even though experts like to say they don't like them, 4 geta bout it they work great! So here's the full detail>> After 3 months in asphalt, dirt, rocks, concrete & the roof of my camper the case is holding up really really well they must have improved them because I saw quite a few say it tears & falls apart, my tie down rings still fine & all edges fine, the energy collected is good, they are 300 watt rated with a PWM it comes with the best I've gotten is 175! WHICH I LOVE If I could always get that I would be freaking happy, I have 1 BBorn lithium bat 12/100 amp hour it was at 18% in 4 hours took it to 94% ((I HIGHLY HIGHLY RECOMMEND A BATTERY MONITOR!)) WORTH ITS WEIGHT IN GOLD THE EXPERTS USE (VICTRON WITH BLUETOOTH) I LOVE IT LOVE IT LOVE IT TELLS ME EVERYTHING, GO POWER tells me NOTHING! My average in full sun is (125-140w) 175w was achieved in full sun with a cool breeze, yes it makes a difference heat actually lowers watts on the portable Dokios, this time of year March April they work fantastic California 60 70F with cool breezes. I achieved 40-70w in the shade which again I was happy, Now as for MPPT? I have the Rich MPPT but have not reconfigured the Dokio SAE wires, I believe with an MPPT I could be getting 200-220 watts? (ONLY WHEN THEY WERE BRAND NEW COULD I HAVE ACHIEVED THIS) I think after this much time (7 MONTHS) & different locations, weather & charges no way, All in all I say {DO NOT BUY) if I had 1 less panel (the 3 panel is by far their biggest seller) I don't think I would be as happy, I waited to get the 4 panel monocrystalline & I would say get 4 because they must be better then 3 (I would love 2 test that!) These are easy to store, travel well, set up so easy! & carry is a breeze. Overall 4 stars because (originally because they were new) they are not close to 300, are expensive, & don't have an easy option for an MPPT hook up. UPDATE AFTER 6 MONTHS DAILY USE>> They are diminishing to fast & are now down to about 80w full sun, (50w 9 months!) the rings did all brake so added holes in the frame (very easy & safe) PWM is fine & an MPPT would not make much of a difference with this small amount of power, I will be adding a Rich Solar flex cigs panel (the cigs is JUNK!) HAD MAJOR ISSUES FINALLY GOT A STORE CREDIT) so with the Dokio working as it was the combo would be perfect, sadly these Dokio are dropping FROM 135w new TO 50w 9 MONTHS, was a fantastic collection of power for 1 battery in the beginning. Not sure now about how long I will be able to use & now can not recommend at the price I paid I simply want 'portable' panels to work for 2 years at least. I would say put the money to morepowa Solar 100w solid or portable multi-mount ( u can place mounted or portable) & forget the Rich Solar flex 80w flex 'cigs' panel. with hard frame solid glass portable & 1 solid on roof would then be in real good shape for 2 batteries. I have learned a lot in 9 months on the road & having both portable & fixed I truly believe is the way to go.

Right now I'm charging my battery in my car using my solar panel. It's doing a good job charging very fast. And it's low light I'm parked in the shade. But I do have a problem that it's case is very soft and and somehow or another it seemed to crack you can see in the pictures where it cracked the panel it doesn't seem to affected so far. I used it on a very hot day last week to charge my power station this was the reason I got it cuz my other one didn't work very well but two things I've noticed the connector from the cable that leads from the panel isn't very tight and as the day got warmer it kind of slipped off instead of gripping tightly so I had to put gray tape around it as you can see in one of the pictures it helps a little but not a lot it seems to be loose on the inside I'll probably have to replace that. The other part is the manual isn't very informative of course nothing they make nowadays is quite informative as it used to be they think everyone automatically knows everything. So I got this connector for my power station I had to tape that too because it kept falling out so the connectors in this set aren't very good the little controller seems to work nice for charging the battery and it has two USB connectors on the side which I attached my phone too and it didn't seem to charge up very fast but at that time the light was a lot lower anyway soon as my power station hits 60 I'm going to disconnect the panel from my battery and connected up to the power station seems the battery is about 3/4 of the way charged from where it was other than being flimsy and the parts not connecting tightly I do like that it charges at very low low light. For the price I paid it's okay what the cracks in the panel I don't know if it's waterproof anymore or weather resistant

I like the fact that it's a set with multiple connections and a solar charge controller. Can't vouch for the efficiency just yet as I've only measired half the capacity charging a power station. But it's light and a complete set, Get it for around $65 or less and it's good value

Lightweight, thin, effective , what else could I ask Léger ,mince, efficace ,quoi d’autre voudrions nous

折りたたみのソーラーチャージャーが欲しく、値段が安くて軽かったこちらの商品を購入。ポータブルバッテリーの充電に使用しました。 80wということで、容量として足りるのかが不安でしたが、3月の晴天時で30wから40wの発電量で、庭仕事をしている間にしっかり充電できていました。そもそもポータブルバッテリーなので今のところ車中泊で使う程度であり、シガーソケットから充電(15wぐらいでした)もできるため、私としてはこのぐらいの出力で問題ありませんでした。 ちなみに私が使っているのはsu○okiのポータブルバッテリーですが、ソーラーチャージ用の端子がこちらのものと違っていましたので、ワニ口クリップを追加で一つ挟み、DCプラグで充電して使っています。直接繋いだらもっとたくさん充電できるかもしれません。 インジケーターも付いており、大変良い買い物をしたと思っています。耐久性も今のところ不安は感じていません。

Rien a redire, c`est pratique qu`il y ai deja le convertisseur.

Well im always a suckered for a bargain so I decided to get a new version of solar panels to charge the ye ol' battery stations while it wason sale. The good.. compact, decent quality, comes with a controller. The ok.. I always have lower expectations on output, but ill admit this style of panel in full sunlight at an appropriate angle I had hoped it would have been better, but it was still good. The bad? Only minor issues. The amount of connections you have to use to adapt to your model is a bit much and the design is a little bare bones. I have lesser models that are a little more protective of the panels and would have better storage for the many adapters. In all, I am still satisfied with it. Good output, compact thin design makes for easy storage, but its a trade off for a more protective case and storage. **Does not include a DC8020 adapter for newer Jackery units.**

This solar panel kit is awesome. I connected it to my battery box from my spare battery after upgrading to a lithium battery in my trailer and it keeps it charged all day and then I use the battery box all night for my projector and charging my phones during offgrid cramping.
