DOKIO 300W Portable Foldable Solar Panel Kit with Charge Controller

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.

Please keep in mind that when it comes to solar panels the wattage rating usually equates to what is possible under laboratory conditions and just about never can be recreated in the real world. With that said, here's my review: As the headline reads, this is not exactly 'light'. Surely easy enough for one person to move around and deploy and it folds down to a size that was easy enough to find room for behind the front seat of my truck. Since my RV already has a decent MPPT charge controller I decided I'd add on to the existing one (besides the included controller that came as part of the 'kit' HAS to be protected from the elements (direct sun & moisture) so was of little use to me to use along with my existing one. The 'kit' came with a ~10' cable that has connectors on both ends to use hooking it up. One end has a SAE connector that plugs into the panel and the other end I cut off and replaced with Anderson connectors. A word of caution here: Due to SAE's 'keying' the +/- wires will reverse unless a little SAE-2-SAE adapter is used to change the polarity of the wires. Given I don't live in a LAB and I'm above the 45th I did not have high expectations for this panel. However it was a bright and sunny day in May and with a clear view of the sky (not a cloud in it) I set up the panel in my front yard. My existing solar panel (68W) was putting out ~40W when I plugged Dokio in parallel to it. The solar panel wattage reading on my phones Bluetooth app went from ~40W to ~210W after plugging in the Dokio - showing that the Dokio 220W panel was providing ~170W of the ~210W total. IMHO: not bad! I plan on adding a fused SAE connector on my RV and keeping the panel behind the front seat of my truck. While the included cable is far to short (I ordered a 25' SAE-2-SAE cable from Amazon) this will come in handy to add more 'juice' while I'm out in the wild - which is mostly what I do when I go out camping, I rarely have RV hookups even when I camp at official campgrounds. (I'm a boondocker!) Granted, had I not already had a better solar controller installed I could of wired up and installed the one included in the kit. Sure, it is fairly basic but at least it has different battery type settings so you can match it to what your using. I should note that when my panel kit arrived all that showed up was the panel box, nothing else! I contacted Amazon which asked me to contact the vendor and within 24hrs they responded and 48hrs later a FEDX truck dropped off the rest of the kit! I'd say very good support from the vendor! To conclude I'd say that so far I'm happy with my purchase and the support I've gotten from the vendor. :) UPDATE (9/22/2022): I've tried using the panel a number of times since purchase. As an example, I currently have it set in my front yard attempting to charge a power brick. While @ 9AM the sun is low in the sky the entire panel is 'lit' with sunlight but only putting out ~50W of power. As a 'control' I also plugged in a 100W panel and only got 25W out of it.

I've been looking at this solar panel for quite a while, and waiting for the price to drop. Just before Christmas 2023, it went on sale with a coupon and only cost about $85. That was a good enough deal for me. The unit itself is decent, but a bit big. It measures a little over 2 ft by maybe two and a half feet when it's folded up but at least it folds flat. There are handles on the outside as well as a storage pocket for the wires and the little controller pad when using for charging 12 volt systems. I hooked this up to my Jackery portable power system. I then tried different places to set it to charge. I tried in my backyard and with one half of the dual panel shaded, it was charging at about 12 to 14 watts. When I put it on the roof of my car in the driveway, it was charging at 27 watts. I tried putting it inside on the rear luggage cover of my Subaru, with the tailgate closed, but it was only doing about 7 or 8 watts. I put it in the front window of the car, facing the sun, sort of like a sun shade, and it was pulling about 14 or 15 watts into the jackery. As long as this holds up, I feel it's a very good bargain and a very good item for when you need to charge your portable power bank or even keep it on your car as a battery tender or battery charger. I hope it lasts for at least a few years. At over $100, I didn't feel it was a good enough bargain, but when it went on sale I felt it really was a good deal. Let's hope I'm not proven wrong. Only 4 stars because of the price point. Also, I wonder about the overall strength and lasting power of the solar panels. Sometimes it sounds like they might crack if they flex a little bit too much. Also not sure how well it would do in damp environments. The box itself that it was shipped in had a big logo on it stating to keep it dry.

I have the 100watt and the 300 watt panel. These have consistently hit 75% of rated capability! I’m completely impressed. I did find you need to use another SAE connector that changes polarity to have them work properly! That’s what I’ve done. I would buy another panel in a heartbeat!

I have tons of experience with solar panels as I have been living in a van for nearly 5 years. This is by far the worst solar panel I have ever purchased. It won't work at all even if it's a little bit cloudy whereas every other solar panel I've ever purchased still works when it's cloudy it just produces less power. This won't produce power at all unless it's perfectly sunny… I live in California for the record. Update: after a few weeks nothing has improved. These are the worst solar panels I have ever purchased. Even the connectors are loose you plug it in and you go to set it up and by the time you have it all set up the wire has fallen off so now you have to reset up everything. Even the connectors that go into your battery to charge your battery don't stay in I have to tape up everything just to keep it connected. The solar panels have made my life extremely harder and I'm super disappointed because I can't return them because they've been used so there is dirt on them

This works well keeping everything charged for weeklong gigs in the motorhome. I read other reviews where people mentioned that it didn’t hold up for long-term use out in the weather. If you read the description, It’s clearly not designed for a permanent kind of set up. The panels are foldable and in a nice nylon covering with handles. It is great for maintaining batteries while vacationing around. Easy set up takedown. If you are looking for something to maintain your batteries while your rig is parked for a long-term, get something hard sided and meant for that purpose.

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.

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...

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.

The DOKIO 160W solar panel worked great when I first got it, but after a while, it stopped working. I reached out to their support team, sent a few photos, and they quickly sent me a replacement — no hassle at all. Really happy with how they handled it. Sometimes you get a bad unit, but DOKIO stood behind their product and made it right. The new panel works perfectly. Highly recommend!

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