DOKIO 150W Portable Foldable Solar Panel Kit, Compact 21x20in Design 7.3lb with Standalone Controller and USB, Monocrystalline Charger for 12V Batteries, Power Stations, RV Camping Emergency Use

Added these to my anker power unit. Have worked great the couple of times i used them

This review only applies to the panels themselves, I do not use the rest of the kit. First off, for those saying these don't product 300w, you need to understand solar panel ratings. They will produce 300w in more or less perfect conditions. So for example mid day late summer clear Texas sky pointed right at the sun absolutely they produce 300w (each set). I only use the panels, not the other stuff as I have a parallel cable setup with a pair of these panels and in the right conditions I get a full 600w out of 2 of these into my AtemPower DC to DC charger / MPPT charge controller. Your limitations are going to be environmental conditions, and your charge controller / power station setup. I run my camper electrical, 12v fridge, USB chargers, laptop charger, CPAP fans etc... and this has no problem keeping the batteries recharged / topped up. My only issues, and they are kind of the nature of the beast as it were are... #1. No included / build in kick stands to set the panels up to actually face into the sun directly. No big deal. Dokio has them available through Amazon, just don't forget to buy them, and carry the hex key with you... #2. Water resistance. You are NOT going to be charging up in a deluge no matter what, and Dokio claims their materials are water resistant, but immersion can be a problem. Keep the connectors pointed to the TOP of the panels, and if ponding / flooding is a possibility take them down and move them inside. Simple enough right? I opted for portable panels instead of roof top mounted panels on my camper to allow me to move the panels as the sun moves to keep them oriented to the sunlight to keep charging going. These are great for that, until some jacknugget pulls his big a-- fifth wheel just to your south giving you nothing but shade. Not the fault of the panel, and remember, portable, just move them! Liked my first set so well that I did get the second and built the parallel cable, so instead of 300w coming in at 18v, I now have 600w at 18v coming into my MPPT controller. (33-1/3 amps). This came with a simple MPPT charge controller, and a bag full of adapters for various power stations, none of which I use and I am not reviewing them. My only desire for any kind of upgrade is, I wish they made these in a 500w capacity, so that I could pair up 2 of them into a 60 amp controller and get 1KW into my camper, 600w is good, 1KW I can at least run AC for a while on...

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.

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.

We love this and use it to charge the batteries on our boat!

I got the 200w version of this and I haven't been able to pull more than 80-90w during the best possible conditions. Even with 35% loss it should still be able to pull at least 130w. But at least that came with all of the cables. I then ordered the 300w version thinking quality control would be better. First one arrived with scratches on the panel and missing the SAE to xt60 cable and I was only able to pull 180w max. Ordered a replacement, that one came in with minimal scratching but ALSO MISSING THE SAE TO XT60 CABLE!! However, i was able to pull 195w. Still pretty terrible but I guess it's better than the other two in terms of conversion loss. all boxes were sealed with the dokio branded tamper proof tape. The panels are light weight, I love the portability and the carrying handles and pouch are a nice touch. I want to take a risk and see if their 400w version has better quality control but I don't think I will be going with this brand again.

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...

Parfait pour mettre dans le VR. Le contrôleur est assez basique, j’ai acheté un MPPT avec module BT. Mais le contrôleur inclus semble quand même correct après essaie.
