FlexSolar 40W Foldable Solar Panel Charger with USB-C and USB-A Outputs for Phones, Power Banks, Tablets - Waterproof for Camping, Hiking, Backpacking

As solar generators are becoming popular I whimsically bought a lower end generator. This of course incited my curiosity about, solar panels. The flexsolar 40w (by the way they should change their name or modify it, as 'flexsolar' pulls up all sorts of other products), is highly appreciable. Had it not been for two videos on Youtube, about this product, I would not have taken notice. I ran across this panel while researching other, solar generators. I was waiting for pay day to buy another panel that was on sale for $50, a 60w portable panel. I missed the sale. Then flexsolar popped up, I really liked the ipad pro 11" size of the panel, when folded up. And, the youtube video was getting 35 x 38 watts on a cloudy day. (The clouds would make that number dipp significantly.) This was significantly better than other small, portable panels, that would only get half the wattage touted by their adverstising (anker, and others). It has been a several days since this panel arrived. Today is my first full sunny day. I am very famillar with a rav power 20,000 mah portable battery that I own. I charge it with an sd pd 61 watt and 30 watt ravpower ac cube, constantly. Lets just say I was not in the least bit displeased with the speed at which it was charging on solar. This panel has an old style usb port, a usbc port and a dc 5221 port. I was able to obtain from amazon a male to male dc 5221, a male 5221 to usbc male cable, and I already own the old school usb cables. The panel does not come with cables but if you have a usbc male to male cable you can use it for your usbc device, though I do reccomend a usbc battery rather than directly into your ipad, macbook air (there is no problem charging iphone or mac book air directly, but when you charge a brick, you do not have to leave your phone or computer vulnerable), they do sell usbc to lighntning cable for iphones. It is rather crazy that I can get input above a thirty watt wall charger, from direct sunlight. I could potentially buy another panel and parallel charge with an adapter, increasing my watt input potential. The panel is well built and in all probability will take a few years of abuse. I have lived through a few hurricanes in a major city with no electricity for in excess of two weeks. I also lived through the Texas power shutdown in our unusual freeze. This device would have been a game changer. In the freeze, even a small solar generator paired with two of these panels and the right cables in parallel, can run a 12v heating throw blanket, charge ipad, laptop, and run fans. A ten watt LED lamp is a god send after being in the dark all night long, not to mention all the books, and movies to make it through entertainment wise, knowing these solar panels can and will charge my portable batteries. I am very happy and am seriously considering another panel from flexsolar. *This panel could charge my phone in less than an hour of direct full constant sunlight. *This panel folds down into a shape comperable to an 11" ipad pro, though definately thicker and heavier. 3 lbs maybe. It is not that noticeabke in a backpack. It is an apppealing pannel, shape and feel. *This panel could potentially charge my 20,000 mah usbc battery brick in three hours. A 42,000 mah solar generator battery in 6 hours. *This panel does not have "kickstands", it does work laying flat, but something to prop it toward the direction of the sun would increase the watt potential. This is my first step into solar and I sincerely believe I have made a good first step.

Solar panels represent an endless supply of power. As long as the sun shines - and we are not foolish enough to nuke the sun (see the Matrix) - its power can be harnessed through solar panels. For years I had been waiting for solar panels that would be a truly viable alternative to electricity. That day has arrived. This solar panel is efficient, and really works. It charges my devises effortlessly, even in less than optimal situations. This will accompany on my camping trips and travels to developing countries. It will also be a companion to my Anker 521 portable power station, for emergencies during power outages. My only gripe is that at time of purchase only the 10W, 15W and 40W versions were available. The sweet spot would have been between 20W-30W. The 10W-15W versions are a bit underpowered and would be ideal mainly for cellphones and tablets. It only comes with a USB-C connector. The 40W version, while having a small form factor when folded, is too lengthy when spread out to be truly portable. But it does add two more connnectors: a DC connector and the older USB connector. It would have also been nice to have ”legs” to angle the panel towards the sun, as opposed to merely spreading it out on a flat surface or hanging it by its grommets. The sun is not always directly overhead. Still, the minimalistic form factor of this solar panel as well its impressive output makes it the best that I have seen so far. I was impressed enough that having acquired the 15W version, I have also bought the 40W version. Update: While I am quite impressed with the 15W version, I haven't been with the 40W so far. The maximum wattage I've derived from it is 20W. Of course, since it is much longer and doesn't have any stand for angling it more precisely to the sun, optimal positioning is more difficult, so this could be somewhat my fault. I'll post as I experiment more with it. I am also disappointed that it does not come with any kind of corded charger. The DC connector is not commonly found, and it would have been nice if one was included, or if they made one.

Avid kayak camper. Got this solar panel to charge a power station but found that the station prefers a slow charge which kinda blows the solar idea. i got the power station to charge my phone and other electronics i use while camping. Ironically this solar panel charges my phone and those other electronics quicker than the power station including my bose flex Bluetooth speaker. It has 3 outputs, but the one i recommend is usb c. It spits out the most power from that connection so get yourself a 100w c to c cable. I got a 10' so i can have the panels in the sun while the electronics stay in the shade. Im also a tradesman and use my bose speaker everyday but the battery doesn't go all day, but it does with this solar panel connected to it. I gave it 4 stars because it doesn't put out nowhere near 40 watts because my power station tells me the what its recieving, but it does effectively charge my devices provided the sun is out. It folds down very compact and very easy to carry. Im satisfied with my purchase, but would recommend to hold off until a sale or coupon or a bundle offer. If it was a true 40 watt, it would be worth the full price, but it's not so it's not.

Works great and the power output is as advertised.great for camping or during outages

This is a great small folding panel. It will charge via usbc, usba, and a 5.5x2.5mm socket. It is enough to keep a phone or small tablet charged in good conditions, and will charge a battery bank in a few hours. It's best feature is the light weight and small size. It has produced over 30w multiple times for me, and like all solar panels, don't expect the full 40w outside a test lab. It is a good value for the size, weight, and solar production. Use at least a 60w rated usbc cable to get the most benefit.

Ich habe mir das 40W Faltbare Solarladegerät mit ETFE Monokristallinem Solarpanel zugelegt und bin absolut begeistert! Die Flexibilität und Portabilität dieses Ladegeräts machen es zum perfekten Begleiter für Outdoor-Aktivitäten. Selbst bei komplett bedecktem Himmel hat mich dieses Solarpanel nicht im Stich gelassen. Es hat tatsächlich Energie geliefert, wenn auch nicht genug, um meine Geräte aufzuladen. Aber das erstaunliche daran ist, dass es selbst mit minimalem Tageslicht (keine Sonne) genug Power generieren konnte, um meine Geräte anzuschalten. Das ist wirklich beeindruckend! Die Verarbeitungsqualität und Haptik des Solarladegeräts sind einwandfrei. Die hochwertigen Materialien, insbesondere das ETFE Monokristalline Solarpanel, machen einen robusten und langlebigen Eindruck. Das Falt-Design ermöglicht eine einfache Aufbewahrung und macht das Ladegerät sehr handlich. Mit den 3-Port USB PD18W QC3.0 Type-C Schnellladeanschlüssen kann ich mehrere Geräte gleichzeitig aufladen, was besonders praktisch ist. Die IP67-Zertifizierung gibt mir außerdem das Vertrauen, dass das Ladegerät gegen Staub und Wasser geschützt ist. Alles in allem bin ich äußerst zufrieden mit meinem Kauf. Dieses Solarladegerät ist eine großartige Investition für alle, die gerne draußen unterwegs sind und ihre Geräte auch in abgelegenen Gegenden aufladen möchten. Es hat mich positiv überrascht und ich kann es ohne Bedenken weiterempfehlen!

Bonne efficacité. M'a permis de garder tous mes appareils électroniques chargés oendnt un voyage de 6 semaines. Assez robuste pour les activités de plein air.

Nutze es seit mehreren Jahren immer wieder bei Zeltlagern o.ä. Die Leistung finde ich für ein Smartphone völlig ausreichend, bei voller Sonneneinstrahlung sogar schnell. Besonders gut und wirklich essenziell ist die Elektronik, die das Laden regelt. Es gibt drei Stufen. Schwach bis stark. Die Elektronik schält je nach Sonneneinstrahlung zwischen den Modi hin und her. Dadurch passiert es nicht, dass das Smartphone bei Wolken mit "langsam laden" startet und dann bei Sonne im langsamen Modus bleibt. Stattdessen schält das Panel kurz das Laden ab und startet mit höherem Strom neu. Klasse! In welcher Stufe das Panel grade arbeitet wird sogar mit einer LED angezeigt. Hatte das Panel auch schon bei Feuchtigkeit und Regen im Einsatz - keine Probleme. Dass die Elektronik mein Handy entlädt hatte ich nie. Mittlerweile würde ich mir immer wieder wünschen, dass das Panel mehr als 5 V ausgeben kann. Zum Beispiel weil mein Laptop leider nur ab 15 V lädt. (Ja, ich weiß, zB MacBooks können auch mit 5 V langsam laden, ich habe das schon bei HP als Feedback gegeben.) Natürlich wäre der Strom dann sehr niedrig. Und vermutlich wäre die Elektronik dann aufwändiger, weil ein Voltage-Booster nötig wäre. Keine Ahnung, wie realistisch / sinnvoll das alles wäre. Ich wünsche mir halt, dass ich mit einem Panel alle USB Geräte laden kann.

Usato in campeggio per 12 giorni,ricaricato powerbank e smartphone senza alcun problema.

Wij hebben deze zonnecel aangeschaft voor het kamperen met de tent. Wij gebruiken daar nooit stroom. Nu met deze uitvouwbare zonnencellen, kunnen wij onze powerbank opladen en daar weer mee al onze telefoons, reader's en elektrische tandenborstels opladen. Na ontvangst heb ik de zonnecellen even getest en in ongeveer 2 uren was de powerbank (22800) opgeladen. Was niet constant stroom. We zijn dus zeer tevreden.
