Great Item and good value
Fairly lightweight. Charges battery pack really well. I'm not sure about the sunshine level or timing, because I tend to leave it outside the tent charging the battery pack and it's usually charged by the time I return even when there isn't much sunshine. Great value for money.

Decent solar panel, gains around 25 - 31w
I have used this to charge a Anker Prime 27,650 mAh Powerbank, it charges at around 25w which isn’t 40 but it’s still good. (I have only used the USB-C and USB-A, I am yet to use the DC 5521 (next review I will have). The output is more that what is said by FlexSolar which is great, no complaints there. It is a little expensive but for the purpose of being portable, it’s great. Very easy to use, it even has a red light which activates when the solar panel receives enough light to create electricity. Updated Review with DC & Anker C200: Yesterday, I charged 90% in a full day which adds up to 54,000mAh / 60,000. Keep in mind I also charged a full phone which adds up to around 3,500mAh. The solar panels are pretty decent, on a good day, in a good position you could get up to 31w through the DC cable. (It is a DC5521) I do consistently get around 25w in full sun, no clouds at around 90 degrees. It is a decent panel which does require strong amounts of sunlight. If you have the extra £10 (when on sale) I would definitely prefer to get the 60w rather than this 40w since the output is around 62% than what is claimed.

Good portable solar panels, but not the power rating you may think.
It should be noted that 40w is under lab conditions. In reality panels heat up in sunlight which reduces their efficiency and thin portable panels rarely give the rated value. In direct UK summer sunlight around 25 Deg C, I get about 12W max out of this kit. That is still very useful and can be used to charge up most small-medium devices, medium power banks in say 6 hours or so or more. I like that these are portable. One thing to not too is that USB A connection and cable will limit you to around 3W, so best to use the USB-C connection to get upto 20W+ etc.

Oh What Fun! Charges in the SUN! [oops, yeh, that was a bit of cr%p poetry - sorry!]
Bought this device a few weeks back, during a brief September Sunny Spell. It worked great - happily driving a USB fan, and charging my devices while I was using them in the garden. BUT - just like when (as a teenager), I was given my first Golf Umbrella, and then it didn't rain for about 3 months (or so it seemed), the day after this solar cell arrived, and I gave it the first testing, the Sun went on its hollibobs, and we had weeks of grey skies, and drizzle/rain/worse. Hey, that's life. But the IMPORTANT bits for YOU: 1) It WORKS GREAT - if you have the sunshine! 2) It has USB-A Socket, and NOT some bespoke cable or connector, so it WILL work with ALL your stuff 3) Seems VERY tough, and a total Dead-Cert addition to my Holiday EDC And come next Summer, if the SUN returns - also end-of-Garden duty. Actually, I kinda just love it. Everything it should be, but nothing more. 5 stars with sparkly FX!

Highly Efficient and Portable Solar Charger
I recently purchased the FlexSolar 40W Foldable Solar Charger, and it's been a game-changer for my outdoor adventures. The charger unfolds into six panels for efficient output. The USB-C port with PD 2.0 and QC3.0 ensures fast charging for my devices, and the IP67 waterproof rating means it cam handle unexpected rain. The ETFE material offers high light transmission and durability. Overall, this solar charger is efficient, portable, and reliable. Highly recommend for anyone needing a dependable power source on the go!

Not very reliable!
Broke after a week, was mounted on a 60 degree wooden pole and stopped working shortly after. No rain during this period.

An actual proper portable solar panel! Type c!
I was pleased to find that this panel does not have glass panels. This is a serious plus as they live in my backpack, they even have a little flex to them. The panels are actually embedded in what seems to be a solid rubber so they don’t get ruined by rain! When out in full sun this panel charges my phone quickly on a type c fast charge cable, impressive. Over all I would say the panel is great value for money, it’s robust and can handle the outdoors easily. Folds up to the size of an a4 sheet of paper, just thicker obviously. If 40w is all you need look no further, it’s been helping me for months. Lastly, if it’s a little overcast they still deliver power, just not under full thick rain cloud!

Awesome piece of kit for camping.
Great piece of kit. Does exactly what it promises. Fast charges all of my devices in hazy sunshine and slow charges in slight shade (see photo 2). Also slow charges in dull cloudy weather, if you're desperate for some charge to make a call, etc. Those who say these don't work must not be placing them at an optimal angle to the sun. Make sure that you monitor the sun's position and use the carabiner hooks to mount accordingly. I've just kept all of my devices running through the Isle of Man TT in very changeable conditions and would strongly recommend this product 👌🏻

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!

De kwaliteit is goed, hij haalt misschien niet de 10 Watt maar kom daar redelijk in de buurt. Achter glas onder de juiste hoek kwam ik al tot 6,5 watt. Buiten in directe zonlicht op zo'n 7,5 watt. Deze waarde is al eerder aangehaald en klopt dan ook

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.
