DOKIO 100W 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.

October 9, very cloudy weather, 16:00. The solar panel isn't in the best position, but it's still generating 7–12 W. I think that's not bad considering how cloudy it is and the panel's position.

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

So I've had this 300W Dokio for over a year now. Originally I purchased their 110W model 2 years ago (2022) and it produced a maximum of 65W. Fast forward a year later and a good sale on their 300W model, so I thought I would at least get 200W out of those which would quicken my recharge on my 1000W power station. I was sorely disappointed. The absolute maximum power I ever got from this 300W panel was 160W. Now before you say, well sun conditions, clouds, etc. I live in sunny California. On a clear day, not a cloud in the sky, middle of summer, at optimal angle is where I got it to output 160W maximum. I watched it bounce between 149W and 160W for about an hour. I don't like writing reviews on day 1 since longevity and other things can't be fully tested until after a period of time. Well, I've had these for over a year, used them about 20 times. The fabric is starting to come apart on the front side - its still together, but you can definitely see the wear. This panel has never been anywhere except my backyard, except when not in use it is folded up and stored in my house. I have never been anything but delicate with them, never scraped them across any surfaces, etc. My assumption is the fabric used to hold these panels together has terrible UV protection. The panels do indeed "work", but they are completely overrated by Dokio. This 300W panel should be sold as a 175W panel. Other than the UV damage, they would be highly rated at that market point. At 300W rating, these are terrible. Perhaps the only saving grace, is that many other manufacturers charge between $1.50/Watt - $2.00/Watt for their portable/flexible panels (the rated Watts, not actual) so at approximately $230 for this panel if it were rated at 175W (providing the actual 160W max I received) it would be about $1.30/Watt in cost. But the size would be larger than equivalent performance panels from another manufacturer. So price/performance is good, but everything else is just disappointing.

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 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!

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.

Panel is good. Not lite, but reasonable for its size. Easy to transport and store. Good number of connections. The cable that comes with it could be longer - it’s really too short - had to pick up an extension cord for my purpose. REALLY would be good if it came with a pop up stand like other portable versions. I wanted this for an Ecoflow Delta Pro with an extra battery. There have not been sunny enough days to do a proper full test, but on a day where the sun was in and out and not fully clear the panels hit 200 watts (see pic). Overall, impressed with the purchase for the price

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...
