100W Portable Foldable Solar Panel Kit (19x26in, 5.3lb), with Separate Controller and Dual USB, Monocrystalline Charger for 12V Batteries & Power Stations, RV Camping Trailer Emergency Backup

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.

Solar panels worked great. Installed direct to the house battery in the RV and they kept it charged throughout the day! Great for boondocking

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.

Nov 2023. Update. 3 years later...these last about 2 years top. Now they only put out half the amp they once did. So, lightweught, foldable. I bought new one, problem is, no matter how good a new one is, it will only put out the same watt as your lowest one, in my case, only 4 amps.......u.pdate 2 years later.....i still have these. I use for camping. I put aluminim starps on the top then drilled a hole for a pad lock for to secure them while camping. Then used 30' cable lock so that i can keep them secure when i go fishing or riding for the day or just leave them out for the 2 week at a time camping. I use a 40 amp renegy solar controller. The controllers that come with them are not for me. Im not getting the amps that i was when new but still about 21 amps with 3 pannels. Storing these in the storage carpartment of 5th wheel when not in use are a breeze to take out and get running in a few minutes. I see they make a stand for them which was not an option when i purchased. The stand is well worth it as i usually just lean them against 5th wheel or lay flat. Ends are fabric. Oh. I also use a bike alarm for each pannel to add that extra bit of security. Drive by night thefts of generators somtimes happen in az campgrounds. Also. Without a doubt. You will want to pair these with lithiumion phosphate bateries. Battleborn is the way to go. 10 year warrentry. The best deal ever. Only 18 pounds for 100aph battery. The prices are drooping. Buy USA. BATTLEBORN BATTERIES! You can purchase cheaper, but piece of mind that the battleborn batteries are less likly to potentially ignite are worth the extra price espically if you have a good amount of $$$$ investment in your trailer. Solid State batteries are still most likly several years away from consumers. Remember, lifeiPo batteries are real happy with a 14.4 charger specifically for LifeiPo. I also have a new thought about batery use now. Use them as a bank. If you take out 50 amps from a 100 aph battery, youll want to add 50 back in. So, do the math...20 amps per hour from 3 - of these solar pannels assuming full sun and other factors, cable length, connectors is about 3 to 8 hours to fully charge. Of course its all about volts and pairing with the right controller, bateries, charger, and battery management system ( i use victron with a bluetooth interface module) will maximize your resources and investment. Again..... Battleborn bateries is what made me rethink this whole solar use idea. They, Battleborn, will help you on pairing all your solar acessories with this awsome battery. Renogy has solar pannels too and in my tests, these flexible pannels are less expensive per watt and perhaps renogy makes a higher quality product, but these pannels have the fabric and plastic framing with handles and are sure less weight than other "camping" portable pannels, i think these pannels are only 14 pounds vs. 25+ pounds for the other manufacturers.... Orginal post....feb. 2021 wasnt too sure about reliability and quality. But. I have 3 of them and they do put out combined 32 amps, so about 10.5 amps each. All pannels are rated but in real world, they usually run about 75% of their rated watt n amps output with considerations of cable length and etc... so, i have deployed them with my 5th wheel for weeks at a time and im pretty impressed. I had high quity fixed ridged pannels which were too bulky and heavy and was getting only 18 amps total so these are very impressive so far. these flexible pannels are pretty darn good. I did use some 1/2 inch eyelets and used a 30' masterlock cable set to enhance security and a security alarm for bikes and other security measures so the they dont wander off. But the cool thing is i can fold them up and store them under better security with little effort. Btw.. check out Battleborn lithium ion phospate 100amp/hr batteries to combine with your pannels. For me, its the only way to go if you like to have generator / electrical independance.. boondock camping with never any generator noise unless you want to run an air conditioner. Yay! Lifpo 4 batteries are the way to go anymore. This is just my opinion only and an honest review of these pannels with some info about a typical application.

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.

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.
