Features
- BIG POWER, STILL PORTABLE Folds to 19.337.41.1in and weighs only 15.2lb, so this 300W panel packs serious energy yet remains slim and easy to move, mount, or store for RVs, vans, boats, and backup use.
- SEPARATE CONTROLLER FOR SAFER CHARGING Equipped with a standalone PWM controller that protects your 12V system from reverse polarity, overcharge, overload, and short-circuitand can be replaced or upgraded later if needed.
- LONG REACH FOR FLEXIBLE SETUP Includes a 9.85ft (3m) cable, allowing you to place the panel in full sunlight while keeping the controller or power station safely shaded for cooler, safer operation.
- KNOW YOUR POWER STATIONS LIMITS Some power stations restrict solar input (often 100-200W). Even under full sun, a 300W panel cannot exceed your units own capthis is normal design, not a defect. Please check your model or message us for confirmation before ordering.
- USB CHARGING WHEN YOU NEED IT When connected to a 12V battery, the dual USB ports provide stable power for phones, lights, and small devices. Even without a battery, they can still work in sunlight for emergency top-ups, though current may fluctuate.
- MONOCRYSTALLINE EFFICIENCY, BUILT FOR OUTDOORS High-grade mono cells deliver better conversion efficiency and reduce mismatch loss. The panel surface is weather-resistant, but avoid leaving the fabric case in heavy rain or strong sun for days to extend life.
- COMPLETE BUNDLE READY TO GO Includes the 300W foldable panel, separate controller, SAE/XT60/Alligator clips, DC5521/5525/35135/6440 adapters, 9.85ft cable, storage bag, and manuala one-stop kit for camping, RVing, or emergency backup.

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.
