Used this to help charge devices on a jungle trek and while backpacking. It takes awhile to get a battery charged but works well, is rugged and withstood getting completely wet in a deluge rain storm. I like it and will continue to use it on trips. Very happy with my purchase.

Even when putting this panel in direct sunlight I only ever see the lowest charging level indicated (red LED). On top of this, charging my phone is constantly restarted, so I actually lose charge while connected. Completely useless.
Me gusta mucho el tamaño y el material ligero.

Por el tamaño se entiende la lentitud de la carga.

I decided to try a battery charger that gets its power from the Sun or very strong light in case electricity isn't working. It works.

Die Qualität und Leistung übertrifft sogar meine Erwartung. Durchdacht bis in die Details, gibt das Sunnybag die Gewissheit unterwegs die quasi unendliche Energie der Sonne anzuzapfen.Ich kenne bereits andere Solarpanel, doch so robust, leicht und leistungsstark wie dieses war bisher keines.Es ist perfekt für Wanderungen und Fahrradreisen geeignet. Und wenn es im Alltag mal nicht gebraucht wird, einfach ans Fenster legen und eine Powerbank anschließen.Klare Kaufempfehlung!

5 Watts sur le papier, c'est souvent décevant dans la réalité, mais 5 Watts effectifs, c'est suffisant pour mes besoins. Ce petit chargeur solaire (en un seul panneau, moins compact au transport que s'il était pliant, mais plus facile à mettre en œuvre) tient ses promesses ! Je voulais un chargeur efficace et abordable, pas spécialement puissant mais capable de recharger en parallèle 4 piles AA 1.5V au lithium, et celui-ci fait très bien l'affaire. Un gros plus: l'indicateur de charge (diode tricolore) qui permet de trouver facilement la meilleure orientation (lumière bleue) pour optimiser la charge. Je l'ai testé dès réception, depuis ma fenêtre, et j'en suis satisfait.

Il pannello è leggero e sembra robusto (da testare in cicloviaggio).Dimensioni esterne 17x24 cm solo la parte operativa delle celle 12,5x22 comunque meno di un foglio A4Molto pratici gli occhielli in metallo posti sugli angoli che mi permetteranno di agganciarlo sopra i bagagli sul portapacchi posteriore, su quello anteriore o sulla borsa da manubrioprova praticaTest in condizioni ideali oggi 30-03-2023 in assenza totale di nuvole: collegato il mio dogee s97 pro con batteria da 8000 mah acquistato a gennaio 2022, il pannello è posizionato in condizioni ideali (cioè perpendicolare alla luce ed esposto a SUD) si è accesa la spia blu che indica una erogazione di 0,8A.Dopo esattamente un ora (dalle 12:27 alle 13:28) il telefono ha incrementato la sua carica del 12% (dal 65 al 77%) avendolo anche utilizzato per una chiamata di qualche minuto, un pò di chat via whatsapp, gps e connessione internet accese.In condizioni meno ideali ma più reali, cioè con erogazione a 0,5A e luce verde accesa, sempre orientato a sud ma inclinato rispetto ai raggi del sole di circa 45gradi (posto in verticale) per un ora di esposizione (dalle 13:28 all3 14:29) il cellulare ha incrementato del 8% (passando dal 77 all'85%) .Si rimanda allo stress test di lunga durata per il prossimo viaggio in completa autonomia, una valutazione complesiva

Using for hiking alongside a powerbank. Works well although best results when aligned properly to sun.

I used it to charge up my power pack and it worked awesome! As for the phone, it was cloudy out so it didn’t seem to charge as quick but I am going to try it on a clear sunny day to see how that works. Over all, I like it. Slim and durable. Charges well.

Dissapointing as I cant be around to adjust its angle to the Sun

I have read all other reviews, i am probably the first review that paid for the product.....I just received the item, and testing the panel out, i am not sure if the sun is unstable or if the sun isnt strong enough or if the panel i received is defective, but the panel is rebooting itself exactly every 10seconds. The Lux meter is showing 11965 lux, and it is only outputting 0.05amps at 4.02v and contining to reboot itself every 10seconds, i plugged it into a power bank and i am seeing itself rebooting every 10seconds, then i plugged it into my s10e it reboots itself every few seconds too and the charge time is 6hours 24mins(currently at 20% charge).I will continue to test the item and update further when i have more info.Update:I have tested the item further as the sun gets more intense. Everything is working great now and charging. 1 thing users should watch out for is, if the Amperage is lower than 0.1? or at where i was at which was 0.06amp, then the panel "probably" believes its an overcast of clouds and reboot itself(feature for IOS). So after the amp has increased passed 0.1amp, then the rebooting stopped.This wasnt written anywhere in the description, but this will probably happen to a lot of people.Other info, lux is not linear to energy output, as the light picks up, energy output increase more than ratio of 1.All in all, the product is well designed, light weight.Rebooting will occur when cloud overcast the panel causing amperage to drop, also the trigger for reboot is probably when amperage is lower than 0.1amp. (Maybe better documentation for that will help other users.)

Great for charging external batteries but not for directly charging phones or tablets.
