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

As someone who loves spending days off-grid, I was looking for a reliable source of renewable energy. This solar panel kit has delivered beyond my expectations. When I first unpacked the kit, I was pleasantly surprised by how lightweight and foldable it was—perfect for throwing in my backpack or car without taking up too much space. The setup was incredibly straightforward; I simply unfolded the panels, positioned them to catch the sun, and connected my devices. It felt almost too easy! On a recent four-day camping trip, I had the chance to put it to the test. Each morning, I set up the panels next to my tent, and by noon, I was able to fully charge my portable power station. This meant that I had enough energy to keep my phone charged for navigation, power my laptop for a little work, and even keep a small cooler running to store food. It was fantastic not having to worry about running out of battery. One evening, I decided to try charging my lights for the campsite. Because of the DOKIO kit's efficiency, I had all the power I needed by sunset. I could bask in the glow of my solar-powered lights without fearing I’d drain my resources. The durability of the panel kit also stood out. It withstood a slight drizzle one day and still performed beautifully without any issues

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.

This is a great lightweight kit. You can throw it in the trunk or back seat. I get enough voltage and amps to charge my 100aH LifePo4 battery with just 2 panels exposed to the sun even in low light. Something not mentioned but is an important feature, the controller has cross polarity protection and corrects if you plug in something not correctly polarized. I would have gave 5 stars except for 3 small things. The controller is a little hard to operate, the SAE plug is very loose and falls out easy, I had to buy a new cable to replace the Original. And it would have been nice to have grommets along the edges to hang from a rope or hooks on a tree or wall. This works way better than I expected.

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.

Performance: I bought 2 of these for temporary use on my sailboat. The idea was that I could normally keep them stowed and set them up when at anchor to help keep my batteries charged. I've used them for about 6 months now and I can definitively say they are terrible. The absolute maximum power I have ever seen them produce in any sun condition is about 50-55% of what they are advertised at. The normal amount with no shading and pointing at the sun is about 42% or 125 watts. I didn't expect these to fully live up to the 300 watts they are advertised at but this is pathetic. I have other panels that will produce as much actual power as these will that are MUCH smaller. Convenience: The fold up design of these panels is the primary convenience factor that I bought them for. They do fold up and stow away as I needed them to. Having said that, they are pretty large even when folded up. These panels have no holes for tying them down or securing them in any way. They are rather difficult to secure easliy. This is a real pain for a portable panel. Durability: These panels are semi-flexible and seem to be relatively tough. They have survived being blown over a number of times due to the lack of securing points. I was concerned they would be damaged but their power output is no more abysmal than it was when they were brand new. The weathering of the fabric that holds these panels together is really bad. You would think that fabric that makes up the frame of a solar panel would be UV resistant. I assure you that it is not. These panels showed significant degradation after the first couple months of use. They still look new on the back but are falling apart on the side that faces the sun. The 12V plug that attaches to the panel is not color coded or marked in any way which makes it easy to connect it backwards. I spent a considerable amount on my two panels and I am very disappointed in them. They both perform exactly the same so I don't think this is a case of a defective panel. I wish I had bought different panels.

I've only had this for a couple of days, but it tests out great. I plan on using this primarily to top up the batteries in my RV. But secondary use will be to recharge my batteries when doing portable amateur radio. First pic shows my testing setup. I ran the solar into a watt meter, then into a 16 Ah LiFePO4 battery. The battery was nowhere near depleted. On a bright sunny day at about 11 a.m. I set this up. For those that don't know, LiFePO4 batteries have built in battery monitoring systems that control the charge going into the battery. From the 2nd pic, the panels were generating 91.2 watts of power at about 6.5 A. It brought that 16 Ah battery to a full charge in just a couple of minutes. Last pic shows the mod I had to do on the cable. Like many hams, I've standardized on Anderson power poles for power connections. I just clipped the cable with the battery clamps and put on power poles. The negatives I see is they are slightly heavier than I expected. I also don't like they don't come with the Anderson power poles already installed. Another is that the charge controller feels cheap, but that's what I expect from an inexpensive solar system. But these negatives don't take off a star. I have a camping trip coming up. I'll update the review once I return and have some details on how it does on keeping my RV battery charged. Edit: we camped for a week without hookups. I was able to put the panels on top of out awning for the entire day and kept the camper battery topped up just fine. I was also able to charge a LiFePo4 battery to run my ham radio rig the entire week. I'm very happy with this solar set up. Picture 4 is there because there was a question asking how big the controller is. It is approximately 4 3/4" x 2 3/4" That's a standard playing card for comparison.

Update. At first I thought I upgraded with a 300 w but the stitching is all coming apart and I've only had this for a few months. I've only used them a few times in the few months and never left them out during inclement weather. there's no little hooks on the 300 w that were on the 220 Watt, which was really handy for hanging them on my car or from a tree. In full sun trying every angle the best I got was 190 watts..still better than the 220dokio They have no support and do best on an angle. I suggest Velcro on back of each Panel to adhere a board to prop up. . Great solar panels they pull in nearly 200 w at any given time even with light clouds. My only complaint is that they have no stand up backing you have to lean them against something and they bend very easily I'm afraid they'll break but so far so good. I suggest treating exterior with waterproofing spray. the material of my last Dokio panels fell apart and disintegrated from the elements even during the short times I had them outside

Works well, first full size panels that I bought. Nice variety of cables included. Depending on your application you may need extensions. Panels are easy to use. The charge controller is a little challenging to operate, but once set performs well. Note that the default setting is lead acid, can be changed to lithium and LifePo4. Convient size once folded.
