400W Foldable Solar Panel, Portable Solar Panel, Solar Charger, Solar Kit, Solar Module for Power Station Solar Generator Camping RV Boat Power Outage Outdoor Garden Balcony

After reading reviews I was not 100% sure if this solar panel will meet its specs but given ease of Amazon return policy I decided to give it a go and ordered it for my recent camping trip. I couldn't be more happy with my decision. Solar panel feel well made. It folds in half for transport and strong velcro does very good job keeping it closed. There are two support legs also secured with velcro. Connector cable to charge power station and set of cables allowing to link two panels together was also included and it sits in dedicated zip pocket. Setting up the panel was straightforward. Open velcro, open up solar panel, get two supports at the back stretched,point the thing towards the sun and connect it to your power station. That simple. So far panel got used on my last trip to Snowdonia. Over last few days I used it to charge Anker Solix C300 DC and it performed really well. On a cloudy day I was getting anything between 20W and 40W output which was enough to top up power station a bit while charging 2 phones. Brighter days resulted in approx 60W output and when pointed directly to the sun I was getting 80-90W of charging power. My solix charged 14% within an hour and that's while charging 2 phones and maintaining portable fridge. I will be using it a lot over the summer and will update this review if anything changes.

The Allpowers 400W panel is a large panel for gathering a significant amount of power. It is foldable and portable but it's bigger and heavier than traditional panels because, well it has to generate 2-4x the power. It is great however for camper vans and off grid living. The panel will quickly replenish your portable power station, it'll keep it charge up during the day and make sure you don't have to worry about running out of juice. Quality of the panels are amazing, energy production is great and setup is simple and easy with the folding supports tucked in to the back of the panels. Great product, fair price considering the quality, very pleased.

It’s ok, does what it says. Max wattage charge we got is 72W and that is at prime time with sunshine. Cloudy conditions we get 5-15W. Good for a last resort travelling.

Once folded up, these are extremely portable. Once opened up and facing the sun, they perform well, charging my EcoFlow River Max daily whilst we are holidaying off-grid. Found them a little fiddly to stand up at first, but there's a way to do it. Basically, connect everything first, then open one array and pull out the stand at the back and seat it, then do the next, then the next. I made the mistake of trying to open the lot and then pull out the velcro fixed stand lol Very good, definitely recommend.

These are great - I've now got three

Easy to use, output is about 100w. works well but doesn't like hot wether, not thats a big problem in the uk. I noticed it stopped producing current yesterday in the mid day sun so I measured the surface temp and the panel was just over 50 C (hottest day of the year I believe). Today its producing about 40 watts on a cool and fairly dull day. I am expecting the wattage to go up when the sun comes around fully in the afternoon, after all I do live in the sunny Staffordshire Moorlands. Hope this helps.

This worked well with my R600 even with limited sunshine. Also at a good price.

It's hard for me to hate on this panel too much, as I'm not generally sure what sort of level of performance you can expect from these. However, on a cold crisp day (so no overheating excuses) with the sun pointed directly at it... I'm getting just over 50W. I may up the review by a star or two if I can see closer to 75W. But right now, very disappointed with the current I'm getting.

Die Solarzellen sind in einem guten Zustand und durch die Verpackung für den Versand offensichtlich ausreichend geschützt. Die bisher ausgepackten zwei Solarzellen kamen in einem sehr guten Zustand an. Eine Anmerkung am Anfang: Eine Solarzelle heißt Solarzelle, weil sie aus Licht (mit breiten Spektralbereich) Strom erzeugt. Das ist ihre größte Stärke, und dummerweise auch die Achillesferse. Die angegebenen 2,5 Watt pro Solarzelle werden unter den Bedingungen in Deutschland selten erreicht. Jedoch waren unter Testbedingungen mit einer Halogenleuchte bei 6 Volt 480 mA (keine Kurzschlussspannung) möglich, was etwas mehr als der angegebenen Leistung entspricht. (Anmerkung: Wenn ihr eine Halogenlampe dabei habt und genug Strom um diese zum Leuchten zu kriegen, ist die Solarzelle meines Erachtens eher ein Gimmick als eine Notwendigkeit). Solltet ihr also gerade in der Mexikanischen Wüste nähe des Äquators bei wolkenlosen Himmel Mittags am Verdursten sein, könnt ihr mit Sicherheit davon ausgehen, dass die Solarzelle optimal ausgerichtet 2,5 Watt oder mehr erbringen wird. In Deutschland beim Sommerfest mit einem Bier in der Hand sind 2 Watt realistischer, es kann aber auch mehr erreicht werden. Außerhalb des Gebäudes in der Sonne im November um 13:00 war die Spannung bei optimaler Ausrichtung ca. 6 Volt und die Kurzschlussspannung(!) 350 mA, im Schatten maß ich eine Spannung von 5,5 Volt und eine Kurzschlussspannung(!) von 50-80 mA, innerhalb des Gebäudes im Schatten 20 mA. Da zwei Solarzellen verpackt sind, kann man bei "normaler" Anwendung (bedeutet: irgendwo hinlegen und liegen lassen, während man sein Picknick genießt) mit durchschnittlich ca. 0.2 Ampere bei 5 Volt rechnen (2 Mal 100 mA), was in Etwa einem Watt entspricht, laut Windows-Taschenrechner und nach intensiven Kopfrechnen. Der iPhone Taschenrechner hat einen Blödsinn ausgegeben, aber wie es scheint ist das normal. Für die Angaben hier gibt es keine Gewähr, da "draußen im Schatten" und "drinnen im Schatten" wissenschaftlich nicht haltbare Ortsbeschreibungen sind.

Test, ad occhio il pannello fa notare che è di tipo policristallino, ossia con silicio a scaglie, già questo fa pensare che è stato costruito bene al fine di raccogliere meglio la luce anche in ombra, la tensione in ombra (, ALMENO NEL MIO CASO.) e di 5, 2v a sole pieno circa 6v,dubito che eroghi un P di 500mah,Prova di ricaricare il tel tramite modulo diretto.. E ovviamente impossibile, Prova a ricaricare 2 batterie 18650 tramite il suo modulo.. Impiegherebbe una settimana,Prova a ricaricare due SuperCondesatori da 2,7v 500F a sole pieno impiega circa 20 minuti, per poi avere un ottima scarica,dopo alcuni test ritengo che il sistema più efficiente sia di caricare i condensatori mettendo i pannelli in parallelo, difatti i C. Danno un ottima scarica al modulo dove andrà inserito il cavo usb.. Il modo migliore è quello di produrre corrente e consumarla tramite i C. Impensabile ricaricare più batterie in breve tempo. Bene o male ho detto tutto. Ribadisco che i P. SONO DI buona qualità e dubito che eroghi o un mezzo Ampere. E comunque sono molto efficienti. Grazie a voi.

Commence a fonctionnait une heure après le lever du soleil 2h plus tard il me donne 50 % de sa capacité et 3 heures plus tard 100 % recharge très bien mes deux petits batteries nomades

Volevo collegare due pannelli in parallelo e nn in serie ed il fornitore mi ha sempre risposto celermente x consigliarmi ed inviato gratuitamente i cavetti mancanti in pochissimo tempo ..ed ora posso ricaricare più celermente il mio accumulatore di energia …grazie 🤩

Très content de mon achat j'en ai racheter par la suite, par contre le prix à doubler en 2 mois 😳
