Power Hungry? FlexSolar 40W Delivers (But Pair It Right!)
I've tested several portable solar panels in rugged conditions, and the FlexSolar 40W is a game-changer, but only when paired with the right battery. Let's break it down: Renogy E.Flex 10W: Ultralight (11.5 oz), but underwhelming: 0.696 watts/oz. Struggled to charge a 5000mAh battery in Yellowstone, even with optimal sun. Frustrating for demanding use. BigBlue 3: Moderate weight (24 oz), better output: 1.042 watts/oz. More reliable, even in cloudy conditions. Still struggled with heavy iPhone recording use. I feel the panel could be lighter with fabric trim reductions. FlexSolar 40W: Heavier (28.16 oz), but powerful: 1.243 watts/oz. The difference maker, but only when paired with a supporting battery pack. Key Insight: Solar panel wattage per ounce is important when you have to carry it on your back or in your boat all day, but compatible battery bank management is paramount. I have found optimal use occurs with a battery that allows for higher throughput charging. An unnamed Battery bank, that allows for 12V @ 1.5A input, allows for very quick recharge times. Avoid Anker battery packs that lack high-throughput charging. Best Battery Pack for Solar: https://www.amazon.com/dp/B0CJC57PPC?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_4&th=1 Real-World Performance: With the correct battery, the FlexSolar 40W effortlessly powered a GoPro, multiple batteries, iPhone, iWatch, GPS/satcomm, speaker, headlamp, and more. Even in three days of limited sun, it maintained essential device power. In ideal conditions charging speeds are very impressive. Verdict: For serious outdoor users, the FlexSolar 40W delivers exceptional power and reliability. Yes, it's heavier, but the performance is worth it. Make sure to pair this panel with a battery that can take full advantage of the power output. Finally, use a HIGH QUALITY charging cable on USB-C. No more than 36" long. Look for something like the Anker USB-A > USB-C Powerline II, which uses a lower gauge wire. If you use a cheaper lighter weight charging cable, you are choking the solar panels ability to push power to the battery BMS.

Versatile
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.

a great product, game changer for camping / hiking durable, simple to use
I did hours of research to find this gift for my son who is an avid outdoor enthusiast. All of the solar chargers have limits, or particular features you may or may not want. So get what works for Your application. I got this because it is light weight, simple design, durable, versatile, and has enough power for 12 volts, not just a phone charger. you can run an. iPad, or charge a camera, or even run a fan, or some LED lights. there are bigger more powerful panels. also heavier, bulkier. this 40 watt it a big step up from one of those battery packs with small panels. so you can get both, this panel can keep your battery packs charged up. For the price, totally worth it, since it can be used many many times, in many applications.

Flex Solar Tragbares Solar-Ladegerät mit 40 W ------------------------------------------------------ Seit langem spielte ich mit dem Gedanken mir ein Ladegerät mit Solartechnik zu beschaffen, leider ließt man bei den meisten gemischte Rezensionen von Gut bis schlecht alles dabei, was natürlich Unsicherheit zum Produkt schürt. Dieses Modell ( 40 W ) habe ich mit einem IPhone 13 Mini via dazugekauften USB Anschluss (0,2m) an einem Sonnig / bewölkten Tag (70/30%) im April 2022 getestet. Das Ergebnis kann sich wie ich finde sehen lassen, aber erstmal zum Aufbau & Location: ------------------------------------------------------ > Aufbau: Ich habe das Panel gezielt nur auf das flache Gras gelegt, ohne Anstellwinkel, weil ich wissen wollte wie es in den meisten Situationen ohne suchen von Anstellmöglichkeiten operiert. ------------------------------------------------------ Location: In meinem Garten eine Süd / Südwest Ausrichtung genutzt welche ohne Bäume / Hindernisse frei der Sonne zugängig ist. Uhrzeit Start: ca. 16:00 ------------------------------------------------------ > Ladeleistung: Durchschnittlich hatte ich eine Ladeleistung von 1 % pro Minute (bei praller Sonne), habe dies mehrmals kontrolliert und mit einer Stoppuhr gemessen, WOW !, das würde durchschnittlich bei einem Akkustand von 0 - 100 %, bei praller Sonne 100 Minuten bedeuten ( 1 Std. 40 ) was ich mehr als gut finde für ein Panel dieser Größe. Mein IPhone 13 Mini hatte bei beginn des Tests 30% Ladestand, und für den Sprung auf 100 % ( +70%) waren 1Std & 20 Minuten nötig, leider hat sich zwischendrin ab und an mal eine Wolke dazwischen geschoben. ------------------------------------------------------ > Powerbank: Diesen Test habe ich noch nicht unterzogen, aber aus dem Netz befindliche Informationen beschreiben eine gewisse Problematik mit den Größen der Power Banks, hat man also eine 19.000 + ...... Powerbank würde diese wohl sehr viel Zeit in Anspruch nehmen trotz der guten Ladeleistung, werde dies aber noch beim nächsten mal testen und den Bericht erweitern. ------------------------------------------------------ > Verarbeitung: Die Verarbeitung sieht robust aus, nichts was sich wie eine schwabbelige Folie anfühlt, oder man angst haben muss das es beim Aufliegen auf Stein / holzigem Untergrund sofort kaputt geht. Auf der Unterseite der Solarplatten ist eine Art aufgeraute Matte laminiert, die Stärke des Panels sind ca. 2 mm. ------------------------------------------------------ > Mitführen Für einen Spaziergang im Rucksack oder Strand, Baggersee, Hütte usw. sieht das Panel wie gemacht aus, die Größe würde ich auf IPad Niveau ansiedeln. Das Teil an einen Rucksack hängen während man damit wandert ? Naja ich persönlich würde sagen zu groß !, eher zum laden bei Rast / Pause aus dem Rucksack entnehmen & laden. ------------------------------------------------------ > Fazit. Für Handy, Smartwatch, Taschenlampen usw. ist dieses Teil bei passendem Wetter ein absolutes Monster ! Lade Leistung bei aktuellen Handys überzeugt ! Von meiner Seite aus Daumen Hoch !

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.

It recharged my 24k Anker power bank in around 3 hours. This solar panel is light and very good quality.
