DOKIO 200W Portable Foldable Solar Panel Kit (20x27in, 9.7lb), with Separate Controller and Dual USB, Monocrystalline Charger for 12V Batteries & Power Stations, RV Camping Trailer Emergency Backup

We tried to use it once in a kinda no very sunny day, and it still charged a good amount to the power charging station. And other time was a great sunny day, and it almost charged our power station. Very easy to use and plug to the station. The only thing you need to be aware is this is a soft solar panel, you will need to find a place or something to support it stand up good for the whole day.

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.

This is the second DOKIO solar panel I have purchased. The first one was purchased back in 2020? and has served me well. The glass panel on the roof of my Tacoma is flat lying so I use the plastic panel as a back-up when the sun gets low or when it's partly cloudy. I have two 4x4s I use to explore the back country. The plastic panel (of another brand) I carry in my 4x4 van no longer puts out the amps so I thought I would get something I know is going to work and take the abuse it gets on my camping trips. I plug the panel into my vehicles solar charging system but it comes with a controller that I have used to help someone else, or use as a stand-alone battery charger. I admit I have not used the new panel yet so I am hoping it's the same quality as the old one. If not I will be back here changing my post.

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。

Pour charger une batterie de 100 Ah qui sert à alimenter mon frigidaire de camping c'est une obligation. 300 watts c'est pas de trop pour compenser la nuit et les journées de temps gris.

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

المنتج جميل جدا شكرا لتعاملكم الراقي ولكنني الشكوى من شركة التوصيل ايميل ولا أستطيع التواصل معكم لحل الإشكال اتمنى التواصل معي بهذا الشان

This foldable 200W solar panel kit really surprised me — it’s super lightweight, easy to pack, and sets up quickly. The build feels solid, and it delivers strong charging performance for batteries and devices, even under less-than-ideal conditions. The included controller and USB ports make it versatile for use in RVs, camping, and emergencies. If you want reliable portable power without lugging heavy panels, this is a great choice.
