DOKIO 300W Portable Foldable Solar Panel Kit, Compact 19.3x37.4in Design 15.2lb with Standalone Controller and USB, Monocrystalline Charger for 12V Batteries, Power Stations, RV Camping Emergency Use

I received the solar kit last night and tested it out from 4PM to 5PM this afternoon when there were about 3 hours of sunlight before the sky went overcast again. The solar panels were directly connected to an Ecoflow power station. The highest solar power that I saw was displayed on my power station was 118W. The highest solar power that I saw was displayed on my iPhone was 113W. The test continued until the power station stopped charging at 100%. The test confirmed this solar kit worked as expected, right out of the box. - Biggest pro: easy to carry and easy to use. - Biggest con: no kickstand or equivalent!! - Confirmed: peak power can reach 118W - Unknown: durability One thing that deserves extra attention: just as demonstrated in 1 of the product videos posted here at Amazon, this kit's solar output is *very* sensitive to how the panels are positioned against the sun. Simply by walking from one side of the panels to the other side, briefly casting a small shadow on the panels, I saw the solar power reported on my iPhone drop from 100+ to lower than 60W immediately and then bounce back. I think this is a good buy. Much more portable than my heavy Ecoflow solar panels. I plan to permanently leave them in my car.

I’ve been working with solar panels for a few years and found them very useful for maintaining my telescope and ambulance batteries while away from city lights. The DOKIO panels I’ve purchased in the past, those with the full aluminum frames and glass, worked well with an MPPT controller, but I needed something light-weight and easy to tuck away, so I purchased this product. The panels meet my expectations, but not so much the PWM Controller, nor the cabling (wires). Although the Controller is rated at 20 amps, it’s the size of a pack of cigarettes and the wiring is too small, so I have my doubts it will work well and last. I won’t rate it here, because I have yet to give it a workout. If you want to get the most out of the panels, then ensure you purchase a minimum of 10 AWG (8 AWG recommended for long runs over 20 ft) wire that runs from the panels to an MPPT Controller rated at 30 amps to be safe. If the panels are charging a battery with a full 300 watts of output at 14.5 volts, then it will have just over 20 amps of current flowing and I never recommend using a controller that is running at its maximum rating like the PWM Controller shipped with the panels. Electronics should always be designed to handle more than its advertised maximum, just like mechanical items should always be built to handle more torque, weight, or sheer force that its rating. If DOKIO sold this package with a 30 amp MPPT Controller and 10 AWG gage wire, then everyone would be happy with their purchase. I also plan to use Scotchgard Outdoor Sun and Water Shield on all cloth surfaces to give it some UV protection (don’t get it on the panel surfaces; use a brush around the panel facing). The panels are flexible and don’t prop up against surfaces without flexing, so I built a frame out of 3/4 PVC pipe (engineered for sturdiness) that can be angled to the Sun and moved when necessary. The frame breaks down to 19 and 23 inch lengths for portability in a small pouch. I do recommend this product, but be prepared to spend a little more to suit your needs.

UPDATE! My original review follows. I am pretty happy with this solar setup. I am NOT into comparing specs or having the latest and greatest, etc.. I have owned this setup for over 1.5 years and use to power my 26 foot trailer with 2 cheap Walmart 70ah batts. I use the toy-like controller included. I camp pretty frequently and would say I've used the panels for 3 months combined days. I am ok with the setup as it is affordable, flexible, easy. My past 45 lb setup with hard frame got to be a chore. These charge my batts within a couple hours in good sun I recharge daily. Panels could use an uptick on ruggedness. And grommets, attachment points so you can hold them in place. Laying on ground is often dirty/dusty, standing flexible panels in wind, not so good. You can build a frame, I just haven't. If you're looking to spend little and want decent capability, these are worth a try. If they last me another 1.5 years (for a total of 3) $300 bucks total, not bad. I think they will last longer if cared for. Original review. Just bought this and used for three days. Delivered as expected. Safe packaging. The panels seem of good quality, though I can see what others have mentioned about possibility of material holding panels breaking down. The photos in the advertising are misleading: these panels will NOT stand up flat like that without considerable support behind them. Support you will pay another $50 to $100 to build (unless you're very crafty) They bend very easily and care is necessary. I plan to take this inside during inclement weather, even wind. I have 2 cheap lead acid batteries that had run out of power the night before due to furnace use in cold weather. These panels charged those batteries fast, and my heat lasted through the night next night. I had a hard framed heavy Zamp 200 watt suitcase a few years ago and to compare I'd say this was considerably faster. I don't measure amps, all that stuff. I want to plug it in and get back to what I'm doing for fun. And there's my single largest disappointment with this package... oddly, Dokio failed to include a cable with the XT60 connector for their controller and an SAE connector for the port on the side of probably 3 million travel trailers out there, like mine. I'm no pro, and so maybe I am missing something... but who wants to take their battery covers off and clamp the controller to the battery each time they want to charge (often more than once a day...)? I really want that cable, say 10 to 12 feet in length, to make this easier for my style of use. The PWM controller that came with this unit is pretty fragile looking too, but it seems to work and I wanted to use the kit as is for awhile. Anyway, for the money, this kit is a go, so far. I hope it lasts a few years.

Very nice set of solar panels just wish they included a set of stands because they are pretty inefficient without putting them on a proper angle to the sun. The company sells the stands separately. The stands they sell are alright but where they weld the rods to breaks easily. I posted a bad review on the stands and the company reached out to me and are sending me another set so they are very receptive to the customers needs. When used at the proper angle these panels deliver. They put out a respectable 8.8amps @ 22.5 volts open circuit. I made this setup more efficient by using a 12gauge SAE extension and a portable MMPT charger as the one they provided is adequate but I need every watt these panels deliver to recharge my Ham Radio battery’s out in the field and and MMPT charger can keep delivering power even on cloudy days . The panels are nice and light so if you have to trek your gear by carrying it a distance this is great and was my main reason for purchasing this brand. They are very thin and folded up are only about 2” thick and about 9 lbs with the controller and cables. They have a nice storage compartment built in. If I can make one suggestion to the company to make this the greatest system. Build stands into the panels backs like a photo frame has so you don’t need a set of stands. It would make these truly light and an even better product. These panels charge a 12.8 volt 20 Ah LIFEPO4 battery from a shut off voltage of 10.1 volts to a full charge in about 2.5hrs in direct sun light. The only gripe that I had was setting the provided PWM charge controller to B4 so it could charge LIFEPO4 batteries. Very confusing but I finally did it. This is one of the reasons I purchased a nice MMPT charger dedicated to charging this type of battery. You can’t go wrong buying these great panels. They also provided a nice set of accessory’s with these panels including a set of alligator clamps and multiple charging plugs. Very well thought out accessories.

they are not 300 watt panels. i suspect they are 240 watt. i ordered three sets of these, they were all supposed to be new, they were all used, but in good shape. two of the sets out put is exact, one set is about 6% less than the other two for what ever reason. this folding panel kit inludes everything but the battery, but the cables are so short you will be sitcking your batter out in the sun to get charged, same with the charge controller. you can buy extensions but you need to know these panels can and i can confirm will output 17 amps @ about 13.8volts, so be mindful of your cables, that is a fair amount of amps for such low volts. the panels are heavier than i thought they would be, which can be a good thing, they fold up and can be stowed easily, but this is also a problem. they absolutly need to do be flat and angled towards the sun for good power production, like all solar panels. i think everyone leaving reviews talking about 140 watts is expecting good performance laying flat, which i understand almost all youtubers show them flat on the ground. so, they need to be propped up and angled correctly, this panel is large and floppy. i built a stand for them and guess what, now i have to tote this stand around with me, making these panels not so portable and easy. glass panels can be leaned against anything and they hold their shape, these dokio panels will flopp and bend under their own weight almost like a wet peice of paper, and they can crack if you arent careful. also, just 4 inches on grass shadow on one panel will reduce its output by almost 1/4. it appears i got more power than anyone that mentioned actual stats, and i used my own equipment to measure this. the dokio pwm controller lies, it will claim 250 watts when i am in fact getting 220 watts for example. i have all kinds of stats i can share, and i can tell you i think i found the cells these panels are made of and i think the manufacture lies about the cell stats which leads to dokio's numbers being wrong. i will tell you just a few more stats: laying the panels flat in the grass i got (not the best day for sun) : 12.72v x 7.16a=91 watts, put it up on my stand and i got: 12.98v x 12.73a=165 watts. i connected two dokio 300 watt panel kits in series on the ground and only got 12.79v x 11.01 amps =140 watts lol. one panel positioned correctly does better than two laying flat, i think the above tests were done around 2pm northern indiana in late february on medium partly sunny day using included pwm controller. since then i have had better tests and better days of sun and found this panel performs just as good on the included pwm as it does on my mppt charge controller. max power i have seen from pwm is 220 watts and about 13v 17amps= 225 watts on mppt, albeit using perfect angle charging a battery with a huge load to ensure max output from panels and controllers. this panel i suspect is made up four panels and i suspect the are actually 60 watts each not 75. also they are wired in parallel, which is not good as it shoots the amps up and while we want good amps it is important to know how V x A = W and we should have high voltage and lower amps going to the charge controller, then let the controller step it down to 12v for the battery. i wish i knew more about the internal construction as i suspect if you were to rewire these in series and ran them to a mppt you could get a 50 foot cable and get about 230 watts from them with the controller and batteries inside where its at least dry and out of the sun. i am returning these as i can and have got three glass panels that will give me about 276 watts wires in series with 50 foot cable run, according to my current test data, for about $240 and a mppt controller for about $100, which i already had for a total of $340 and they can be leaned against anything but i will continue to use the stand i built for the dokio panels. the dkio panels are over priced, they lie about its specs, they are floppy and you need to stand them up, right on the main selling page they say dont even leave them out side for one night which concerns me, the glass panels i got come with a 25 year warranty. i wanted to add that i did more testing today and two rich solar 100 watt panels produced about 98% of the power of this "300 watt" kit. i still like this kit and i bought 3 and decided to keep one, may toss it in a vehicle or take it to work for emergency power, especially since we are headed into tornado season now.

For someone thinking about buying THIS solar panel, I'd say think first about its application rather than it's price, or whether it's rigid or flexible, or anything else. My primary need was simply to recharge my Portable Power Station to 100% - because once it's 100% charged, I can then charge my wireless phone from 0% - 100% 52 times [FIFTY-TWO] ... from my Portable Power Station. What I lose in Durability (versus other solar systems, that are rigid, and "weightyier"), I more than make up for in the fact that this 100 watt [foldable], super compact and lightweight solar panel is perfect for my SUV CAMPER CONVERSION; and especially to fully charge my 300 watt portable power station from 0 to 100% [among other small tasks]. For bigger tasks, I've got a 3000 watt power inverter that is part of a larger solar system running on a lithium battery - and by solar panels [larger than THIS 100 watt foldable solar panel]. Again, consider your need, then match the right solar to meet your immediate need. Look for a Plug-N-Play system, which allows for easier upgrades and power output .

This works great for batteries that are not close to power outlet. I charge machines in my farm that there is no power available and charges quickly. Great tool to have.

I will give this a five star review even though I have not put it to the test yet. I bought the 150 watt version because my power station can only take 120 watt input and I would hate to fry it. It is a solar panel and i do not expect it to ever actually hit 150 watts. Even in the most perfect condition I expect 120 at the most. And my real expectation is more like an average of 40 to 70 watts because I am traveling on a bicycle with a cargo trailer attached. It lays over the trailer nice, but not every panel is getting that sweet spot of sun. I do wish it came with some kind of support to hold itself up, but for 65 bucks it was a very good deal. I am glad I did not go with a bigger one because the 150 watt is about as big as I want to get. I do have a 444wh power station I will be charging with it. I expect it will fully charge the battery in 3 about three days. Theoretically it could charge it in about 7 or 8 hours, but that would be at peak performance all day. Where I'm camping there are too many trees. It was a good price and the controller functionality is great. I like that I can plug usb devices into it directly. Only time will tell. I will update this review in about three months of abuse, I hope it holds up. Seems well built.

I bought it to charge an 1,800W class of power station. It is vary convenient that the various size of DC connectors are provided for. There are no special problems so far, and performance testing has not been done yet.

Panel solar práctico y facil de usar con diferentes conectores para diferentes usos,cumple con todas las características.

The Dokio 110 watt system I set up worked well in cloud and sun. I built a simple plywood support frame and let it go to work. Charging ranged from 24 volts in full sun to 13.5 low in full cloud. It was a good unsettled day to test the unit. I had two 90 amp hour deep cycle batteries hooked up in parallel and my IPad which was at 16% charge from start time. The batteries started with a reading of 12.9 volts and after after 5 hours were 13.5 volts. The IPad was at 75% charge after 4 hours. I also like the charge controller readout screen. It keeps you informed of the performance and constantly monitors the pv output. I can see that we will be able to extend our RVing off the grid considerably without worry about losing power or resorting to a generator. A 200 watt system would likely keep the batteries fully charged but for us, this will do the job nicely. Super happy so far.

Producto bueno, no he tenido la oportunidad de usarlo al 100, pero ha pasado las pruebas

Excelente produto ainda estou comprando os acessórios, recomendo a todos...
