DOKIO 100W Portable Foldable Solar Panel Kit for 12V Battery Charging

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.

I bought this panel to replace a 44 watt Kyocera to charge batteries in my RV. I used the Kyocera and a 10A automotive charger to test and compare the output of this panel when charging the batteries in my RV. All were run on exactly the same circuit through a hard wired controller in the RV. The charger put out about 7A, but this panel put out no more than the 44 watt Kyocera, about 32 measured watts in full sun. I proceeded to test this panel further, exposing just one side at a time to the sun and found that one side put out twice what the other side put out. Even the good side put out only about half what it should have made. The seller had offered to take it back, but, unfortunately, I had moved the controller closer to the battery clamps and had removed the pouch before I tested the panel, so it was no longer in the original condition, a big mistake on my part. The seller offered and I accepted a 50% refund. I really like the way it's set up, but I have no use for another panel that should be rated about 40-50 watts. I concluded that this panel is either defective or just way overrated. If you decide to buy this panel, I'd suggest you test it carefully before you make any modifications. It should produce at least 5A at 13V UPDATE: Almost a year after my purchase, a new customer service manager at Dokio reached out to me to ask what they could do make me a happy Dokio customer. Long story short, they sent me another panel, which I tested carefully and found that it produces every bit of what a 100 watt panel should produce. :-) It produces more than twice what the first panel did. This unit has a lot going for it. It's light weight, low bulk and priced right. The new unit seems to have a couple of upgrades from a year ago and I like the controller. It's easy to understand and has a number of additional settings that make it quite flexible. Bottom line, I think Dokio went above and beyond to correct a situation that was partially my fault. I'm a happy camper! Thank you Dokio!!

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.

For the price its a great panel. Easy set up and folds up and stores easy also. Comes with everything you need to charge multiple devices.

The same problem as other users is 1. It doesn’t produce the rated power, 2. The connections are not working. Was using a bungee cord but now it has totally stopped working so have to change the connectors. Have had this for a year and 3 months. It has been working well, but now sometimes when I pick it up it makes a cracking sound, and it does not seem to charge unless it has full direct sun. Some panels will charge when there is enough sunlight but this panel needs a nice sunny day. With that said, the price is great for a 220 watt panel that can charge well and has been a good preformer. And it’s easily transported. We are a bit rough and pack in the bed of a pickup so that might not be the best for it! The cover for the charge controller bubbled up and came off (no idea why) but it still works.

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.

I own the 110 watt portable solar panel suit case. I have read many posts talking about how this panel will not produce a good charge or just half of the rated watts (so for my case I would expect to see 55 watts). So I decided to test it today. I live in Florida and its almost noon so the sun is at its peak. Yes that is snow on the ground we just had the winter storm come through the panhandle. I have it in direct sunlight and propped the panel up to create a decent angle. I am receiving 13.9 volts by 5.8 amps. This equates to around 80 watts of solar coming in. I am using the 110 watt panel and was hoping for close to an 80-85% efficiency, but I feel like the 80 watts is fair amount of wattage for the cheap price of this panel. I would buy again, but would rather buy the larger 220 watt next time. When you lay it flat on the ground it does pull in 55 watts. This should be expected due to the angle being less efficient. Update: I recently received a Bluetti AC 180 with a built in MPPT Charge controller. I used the adapter that came with the solar panel plugged it directly into the unit and I received the same wattage as I did when using the PWM charge controller connected to a battery. I also have a 100 watt hard solar panel and did some testing with that. I did receive higher wattage (around 15 more watts on average) from the hard/heavy/not really portable panel. So you need to decide how important the portability is. My main usage will be when camping on my boat or to help top off my power station at home. This will still help to charge up my power station during the day so I can use the microwave when I want and possible run my mini-fridge for a few days. Still satisfied with the purchase but still wish I just bought the bigger portable panel.

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.
