JJN 18V 100W Portable Solar Panel Foldable Solar Panels Bulit-in Charge Controller Mono. Solar Charger with PD 60W USB/Type-C/DC/QC 3.0 for Portable Power Station Outdoor Camping Van RV Trip

I've used this exclusively to charge a 300Wh battery pack - with an external charge controller - and it's been great at that for over a year. In ideal circumstances I get about 80w which I think is good for a nominally 100w panelI like the tri-fold design, which makes it more portable. The fold-out legs are basic but work. It's survived rain and dust - just wipe it off and it's good to go!For a low-cost portable panel I think this is a great value for the money

Overall, it’s a great product. I like the tri-fold design. Compared to the bi-fold designs, its size, when folded, is much smaller. The monocrystalline material makes the product very aesthetically pleasing. The dark, shiny black color looks really nice. On a clear summer day it outputs around 70W power, with the current 4.25A. This is not bad for an affordable solar panel. The power output could have been better, but I guess for this price, I’m okay with the result.Here comes the deficiencies.(1) This ALMOST makes me wanted to give only 4 stars instead of 5. Although the solar panel is of good quality, its accessories are not. I have to connect its extension cord and the my power generator’s charging cord through the MC-4 connector. Its MC-4 connecter is stuck with the MC-4 adapter on the other charging cord. I’ve spent hours trying to separate them but it seems that the adapter on this cord was not the right size. No matter how hard I press the pins this adapter won’t let it out. This could be extremely frustrating. Anyway, given this is just an accessory and you can easily buy another one on Amazon, I still decided to give it 5 stars. HOWEVER, future buyers should be aware of this issue.(2) The Velcros on its bag is not very strong so the bag was always left open. Sometimes things would fall from it unexpectedly.

Review of JJN 18v 100w panelsUpdate: 5/12/25I ended up getting a second unit. The powerbank I'm charging is limited to 110w (at this 18v) so two of these panels in parallel does a great job of being able to hold that maximum for hours between reorienting to follow the sun. I've carried them around camping and just 'playing' with it at home quite a bit. The clips etc have held up well, the panels themselves don't show much wear, just a few edges of the material rolling (coming unglued a bit?) but so far purely cosmetic. I really would have liked for these to be able to provide a sustained 100w each, but it seems that real-world performance never matches the rated on any panels. Currently getting about 55w in morning sun (as well placed as I can) and maybe 60-65w in the afternoon peak from each.TLDR: I REALLY like the small folded size of this unit, performs well, default DC5521 plug connected directly to my battery. Not as much actual power produced as another 100w panel I compared it to.This is the panel in the front on the picture (was doing comparisons between brands).Purchased this to charge a 512kwh battery pack by BRiDNA (https://www.amazon.com/gp/product/B0CZLK7F64/).Straight out of the box I was impressed with the form factor. Easy to carry, easy to pack. The cable it came with seems well attached and sturdy enough. Note that it has the DC5521 plug on end, but came with adapter to MC4 as well as a whole slew of barrel adapters (including one that went well to my Jackery 300). Only bad thing here is the 'pocket' for cables/adapters/etc is velcro instead of a zipper - things can easily fall out of edges.As stated in description, there is a 'box' installed in the pocket that has USB, USBC, an DC plugs. I didn't test this but in theory one could directly charge phone or whatnot. I may play with it later and update, but for now I'm ignoring that set of connections as I don't have a use case for them - I don't see myself using it to directly charge phone when I have my bigger battery available that will buffer the power.Running the panels in various configurations next to another brand/make Sunsul 100w (https://www.amazon.com/gp/product/B0CL5WVNSW/) there are differences in performance. This unit seems to produce 5-15% less power in near identical conditions. When oriented more directly (90 deg) to sun, it is closer in production, but when not perfectly oriented it seems to produce less power. I am concluding that this panel has a narrower range peak performance than the Sunsul one. The peak power I've seen reported is 80w (vs 95w on Sunsol so about 20% lower). Peak though hasn't held for long on either panel, sustained 'rely on it' seems to be closer to 65w on this panel - i.e. leaving it running for a couple hours between adjustments.Practical side of this is that to achieve maximum collection of power during the day I may need to re-orient more often. This is where the built in stand doesn't help much - it is pretty much one angle, use it or not.Build quality seems to be there - everything seems well stitched, power cable is secure. The clips feel solid and easily attach/detatch. The power cable does seem a bit thin/light compared to others but I don't see this being a problem given limited amps possible to be pushed through.Between this JJN and the Sunsol I'm rather torn as to which is better. I really want every watt I can get when camping (can't count on sun sticking around all day you know) so the Sunsol wins on that front. On the other hand, I feel this JJN's portability is far superior and I just feel like the closed/folded unit may be less prone to damage (smaller surface, 3 layers deep). I think at the price point ($90 after coupon) it is a great value. If you don't need every watt possible, this is a solid choice.For anyone considering using two of these together with a smaller battery (like I'm running), plan to wire in parallel to keep the voltage within range of the charge controller in battery. I am seriously considering this and will plan to update if/when I do so. This may be my solution to marginal weather conditions.

Performed beautifully. I needed power for my cpap during a totally “unplugged” retreat. So glad I purchased it!

I’m so impressed with the quality of this portable solar panel. It provides a minimum of 10 amps which is twice more than my other portable panels of the same wattage. An excellent value and I highly recommend this for anyone who wants a portable unit.

I used this to charge a battery for my cpap while camping off the grid. It not only charged my battery, but someone else's too.The only thing I wish it had would be a shoulder strap for easier carrying

Quit working in a week. No output.Jjn company never responded to my needs.

I was surprised at how well these worked. I tried to use them to charge a portable power station, which it does, but not at the rate I was hoping for. When it comes on to charging a mobile device this works pretty well. The surface area for capturing sunlight is pretty good as well.Over it was worth it for the price. JPS haffi move off enuh!
