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

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 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.

For the money it's a great option. You will not get 160 watts, closer to 100w. However I just use them as an addition to our rooftop solar in our RV. I built a kickstand on each panel. I changed the controller for an mppt variable voltage that was about $40 and use that to directly plug into our e bike batteries. That works great and charges them quickly and it's set to automatically to stop at the correct charged voltage 54.6v. The bike controller confirms this. It takes on average 1-4 hours to charge depending on how low the battery is. I also charge our 1500w power station with it. I have a fused auxillary connect on my 2 x 75amp lithium coach batteries that I can connect to assist the roof top solar on cloudy days. The fabric does degrade in the sun. You can just use hvac reflective tape or duck tape etc when this happens. For a dollar a rated watt this is worth the money considering the cables and controller. Best to upgrade the controller. I have 2 mppt ones. 1 for bikes other for everything else. Make sure you don't reverse polarity on the connectors, check with a multi meter and have extras of polarity connectors.

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.

Bought 2 of these and took them on an 8 day boondocking camping trip in my 5th wheel to charge my Goal Zero Yeti 1000 power station. My wife and I use the Goal Zero Yeti 1000 to run our CPAP machines at night. I also used them to charge the 5th wheel batteries. Because of several factors (like clouds and the way I just threw them flat on the ground), I still had to run my gas generator a few times. Here is what I discovered: 1. I love these panels and just bought a third one. I also have two heavy Goal Zero 100W briefcase solar panels but they are so heavy I don't like them. Much prefer the DOKIO 160W 18V Portable Solar Panels. Much easier to store. 2. They never produced 160W but my Goal Zero 100W panels never produced 100W either. 3. I love the battery management control box that comes FREE with the DOKIO 160W 18V Portable Solar Panel. I can hook it directly to my 5th wheel lead acid batteries and charge them to full capacity in a few hours (time varies because of lots of reasons). 4. The cheaper DOKIO 160W 18V Portable Solar Panels don't have a kick stand so I had to lay them against a rock or just lay them flat on the ground. This made them less efficient but I didn't have to keep adjusting them like I had to do on the Goal Zero briefcase 100W ones. 5. For the price of one 100W Goal Zero panel I can buy 2 DOKIO 160W 18V Portable Solar Panels. 6. In the morning I lay them flat on the ground, hook them up and don't mess with them until the sun goes down. 7. I just bought a third one and hope I won't have to run the gas generator at all (depending on the weather). If three isn't enough I will buy a fourth one and leave the Goal Zero ones at home. Bottom line: If money is no problem the best solution is to have permanent solar panel system installed on the roof of your RV. But if you buy solar panels you can't go wrong with these DOKIO 160W 18V Portable Solar Panels. Besides while I'm saving up for my home Tesla solar panels and back up batteries, I can use them at home for emergencies. Easy to lift and slim to store in the garage. Highly recommended.

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.

The highest output I could measure with this panel was 74w at zenith in SoCal in late march, with a UV warning. It is however a rich kit of parts, and I think part of the problem with this kit is the wiring, rather than the panels themselves, I'm gonna void the warranty to find find out. For 65$ it's probably worth it for the cables and parts, but if you're not the chop it up and do experiments type, this might not be for you.

I have been very patient to write this review; I have used the panels (purchased 2 rated at 160 W each) under RV field condtions for a year. The panels have been taken care of and not abused in any way. Simply put, the performance and sustainability of the panes is abysmal. I would never in any way recommend their purchase. I have spent numerous hours evaluating the causes of insufficient charging capability of these panels. Even under the best of conditions, even though 2 panels together were rated at 160 watts each, I never actually received more than approx. 80 watts from the COMBINED panels. They have now deteriorated to the point of no more than 40 watts COMBINED, all under the best of conditions. Thee numbers have been confirmed with direct amperage measurements as well as detailed observation of expected vs. actual performance over that year period. You will be able to find other reviews that confirm this experience. I am intimately familiar with my charging equipment and requirements; these panels do not meet or live up to specifications in any fashion nor to longevity. I will no longer buy solar panels unless I have redundant confirmed field testing data as to performance. The panels are substandard and eventually, rather expensive in the end.

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

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!

Works great , I originally bought one to try and worked very well , bought a second one for a total of 320 watts , if I knew how well it worked I would have bought the higher wattage to begin with. Definitely would buy again

Comparto la opinion de otras personas, los materiales se sienten de buena calidad y cumple su función de cargar el generador solar, pero con sol al 100% no he conseguido mas de 60 Watts, que está lejos de ser los 160 watts que presume la publicación, con 100w me daría por bien servido, pero solo 60w por el precio me parece insuficiente.

Es ligero y dice bien y su regulador está increíble, el único problema es que por más sol que había no pude sacarle más de 80 watts
