Features
- BIG POWER, STILL PORTABLE Folds to 21401.1in and weighs only 17lb, 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.

The media could not be loaded. ****Update 4/30/24 I requested a replacement. Amazon sent me new panels. The seller also reached out to me. Panels were delivered the next day and so far they work great. They charge my Lifep04 100Ah battery and I can run the camper AC on a sunny day with no problem while keeping the battery charged. Update**** Solar panel burned after the second time charging a 12V LifeP04 battery 100AH and a 2500W load.... See last picture. I ordered a replacement will update when I get it and see how long it lasts... ************ Not bad, they are easy to move around. No back legs to hold them upright. No holes to hang them from a wall. The Controller is not the best, but a better one to take advantage of the panels. Tested them for an hour, battery went from 11.9 to 12.6 V within 30 minutes on a cloudy day. I haven't tested this panel fully yet. Not bad for the price I paid. The connections are simple, however I had a reverse polarity within the system and I had to switch my battery cables in order to make it work. No a good thing that's why they send you an adapter. Quality seems good, they are flexible however don't bend them to much or they will crack. Cables are short, order extra cables....

I gotta tell you, I decided to level up my pop-up trailer game by adding two 6v golf cart batteries and a solar panel. So, picture this: I slap the panel on the roof before popping up the trailer, and bam! It's like magic - all hooked up to my batteries and ready to roll. Let me just say, it's been about four days since I've been using this setup, and let me tell you, it's working like a charm. Plus, a sweet bonus is that it charges my Jackery like a boss. Totally worth it, highly recommend!

I like the light weight and foldability of this panel and that it comes with a controller and lots of adapters. However, I was disappointed with the power output. On a bright, sunny day, after carefully adjusting it to be at right angles to the sun, I used its own controller to charge a 12V Lithium battery. The controller reported a max of 16 amps. The charging voltage on these batteries is actually 14.6V, but that is still only 234W, or about 78% of the claimed power. I also tried it with an EcoFlow battery system, which reported that it was delivering 160W. Even at that power, it's a pretty good deal for the price I got, which worked out to about a dollar per watt.

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.
