BigBlue 28W Foldable Solar Charger with 3 USB Ports (5V/4.8A Total) Portable and Waterproof Solar Panel + 4 Steel Hooks Compatible with Phone, Huawei, Xiaomi, Samsung Galaxy

I was very sceptical if solar chargers would be any use in the UK due to the mixed weather we have but i was astonished by how good this panel charger is. Used it in the Scottish Highlands over a 6 day trekking adventure in Knoydart. It worked flawlessly, never had to use tge power banks i had carried in my pack. During lunch stops or late afternoon set it up and it charged my phone, head torch etc within about 30 minutes to an hour. Brilliant piece of kit. Big thumbs up from me.

Camping trip essential! Or even some free juice at home! Works very well in full sun, especially when paired with a powerbank. This seems the best set up as the powerbank doesn't use any power. It only stores it, so it can be working away all day, storing up those precious rays,ready for you to use when the s7nbgoes down. Each panel is roughly A4 so it's a little bulky but to be expected to actually be of any benefit! Excellent product 100% recommend

Pros: -With solid sunlight, can charge a phone, and/or similar device, from 0% to 100% within a few hours(Depending upon your Milli-Amp capacity). -3 standard USB ports for charging which can be used all at once. -steel rings to attach clips to, quite durable. -Good stitching and build quality. -LED to display charging potential(Though, this can be deceptive, since it only means it has detected light, not that there's ENOUGH light to power anything except the LED.) -Rubber cover for USB ports when not in use -Charging controller and USB ports are within a pouch, so the device can be left on charge in a container. Cons: -Power supply various dramatically with sunlight degree. a drifting cloud will reset the charing on the phone, turning the screen on. So if you have a 1-minute screen idle before it turns off, and you're charging on a cloudy day, your screen will keep turning on and off because the charge will vary, reducing it's effectiveness. (I suggest leaving the solar panel connected to a power bank and charging your phone from that to prevent this). -Weight is on the heavy side of things considering, but this isn't as bad as other people are making out. -Under direct sunlight, can get warm. Doesn't get too hot though. Conclusion: This is an excellent solar panel for the price. It is portable, though slightly heavy. Thanks to it, and with moderate sunlight, have been able to charge a very big power-bank(26,800mA) within a few days. I have not needed to use a wall socket to charge my 7-odd USB devices ALONGSIDE charging my power bank. I have more power than I need thanks to this panel. So, if you need to charge phones, game controllers, Bluetooth chargers etc, this will do so long as you have good sunlight. If you have clouds, you will have trouble. For the price, it's a good product.

Most of the time it lives on the dash, as in the picture and here in Southern Portugal, even in October, it can charge my tablet, my phone, my ecig and my 30,000mAh from behind the windshield. If in parked up during the day I put it outside the car and it charges everything even more quickly. I spend a lot of the day either driving or away from the car so it doesn't go outside that often. Great design, if I park in a crap area overnight it folds away flat to be hidden as it charges things, even in moderate sun, very quickly. Best solar charger I have used by far and, before I forget to mention it, it is really light for the overall size.

The charger is really great. I was skeptical, but actually it works perfect. It tooks approximately 2 hours to fully charge my Iphone 14 pro at the full sun. I'm very happy with it.

I went to france carp fishing for a week last year, I had multiple power banks and lots of other bits that i needed to charge up whilst over there including head torches my phone and camera batteries etc. I bought this just in case I had issues with the power banks etc. due to being isolated in the middle of nowhere. This thing is seriously great, I used this to charge my head torches and phone every day and even my smaller power bank, in decent sunlight it charged my headtorch and phone to full in a few hours. therefore leaving my power banks to charge my other bits and bobs. It is honestly brilliant, I have sold all my carp stuff as I just decided It wasn't for me anymore, however i have kept this, I use this whilst hiking, camping or just at home in the garden and its sunny and i need to charge something, after all who doesn't like a bit of free electric. If you are outdoorsy and are looking for a decent tough solar panel that can get some charge back in your phone or other tech then look no further. It also has studs in each corner of the panels when folded out and comes with clips to lay this out etc. or fasten it to anything if you wish, I have attached this to my rucksack whilst hiking with the clips and its charged stuff no problems. Folded down it is around the same size as an a4 piece of paper and the thickness of a book. If you are thinking of getting one, then don't hesitate they are blooming brilliant!!

Solar panels stopped charging after just a couple of uses. Unfortunately I was travelling all this time and could not return them. Shockingly bad experience compared to my previous ones which lasted 8 years and still work fine.

This is now my third purchase of this type of product . I can tell you , this one is the BEST so far. As for its charging ability all I can tell you is that I use it on Mediterranean holidays , in the height of summer , with full sunshine all day. Charges my 5,000mAH phone battery to full in 8 hours.

BIGBLUE 28W. PRODOTTO MOLTO BUONO. Consigliatissimo. - VELOCISSIMA RICARICA A SOLE DIRETTO - anche col nuvoloso qualcosa ricarica sempre - Una POWERBANK da 30.000 mAh, se la colleghi al mattino, quando torni la vedi ricaricata piena, già dopo pranzo, basta che dalle 12:00 in poi il sole sia perpendicolare al BigBlue. (Per capirci con una powerbank 30.000 mAh si possono ricaricare FINO a COMPLETA batteria 🔋 piena, 2 telefonini, un Tablet e 2 lampade da tavolo ricaricabili. Alla sera se va via la corrente neanche me ne accorgo, perché sto sempre con le lampade ricaricate e non ho mai problemi di rimanere senza telefoni carichi o senza vedere, continuo le mie attività tranquillamente grazie alle ricariche effettuate col pannello solare sulle POWERBANK) - LA DITTA È MOLTO MOLTO BRAVA E PROFESSIONALE. QUALSIASI PROBLEMA ti rispondo subito, in Italiano e cercano sempre la soddisfazione del cliente. Si capisce da qui la SERIETÀ DI CHI CI TIENE alla qualità e a lasciare il cliente contento e soddisfatto del proprio acquisto e anche loro sono contenti CHE IL LORO PRODOTTO SVOLGA AL MEGLIO, LA FUNZIONE PER CUI È STATO CONCEPITO. Se capiscono che c'è qualcosa che non va non esitano a sostituire il BigBlue. Ne va del loro nome e sono molto contenta del loro impegno professionale. MOLTO SODDISFATTA. Spero sia stato utile.

Wirklich gut! Zuerst war ich skeptisch, da ich nach der Bestellung (Aktionsrabatt) bemerkt habe: es gibt (mind.) zwei Varianten des 28wPanels von Big Blue. Eine Variante mit Ladebox außerhalb der Schutzlasche und mindestens zwei Varianten mit Ladebox unterhalb der Schutzverkleidung. Letztere habe ich bestellt. Bei der letzten Version scheint es zwei Ausführungen zu geben: eine mit komplett schwarzem Solarpanel und eine mit schwarzem Panel und „Silberstreifen“. Ich habe die letztere Variante geliefert bekommen. Das Panel funktioniert wunderbar. Klappt man ein oder zwei Panel ein, funktioniert der Ladevorgang immer noch, dann mit „halber Kraft. Selbst hinter! der Windschutzscheibe des PKW funktioniert die Aufladung erfreulich gut. Die Ladegeschwindigkeit liegt dann etwas über 3/4 des Ladetempos des voll ausgeklappten Panel mit direkter Sonneneinstrahlung. (3/4 = ca. 5% einer 10.000mA Powerbank In 10 Minuten geladen - hinter der Windschutzscheibe!). Top 👍🏼 für diese Variante! Genau das, was ich gesucht habe: Ladung möglich auch bei Teilverschattung und hinter der Windschutzscheibe. Ansonsten: Verarbeitung gut. Hoffentlich auch unempfindlich gegenüber Feuchtigkeit und ausreichend robust. Das wird die Zeit zeigen.

La calidad del producto es estupenda: acabados muy buenos y un resistencia decente. La carga no es milagrosa, pero si que con un sol directo es muy buena. En cuanto el sol no da directamente, se pierde la capacidad de carga, pero hasta ahora no he encontrado ningún cargador por este precio al que no le pase. Desde luego, si uno prevé tener rayos de sol en sus viajes o excursiones, merece la pena. No he podido hacer un análisis tan profesional como el de algunos comentarios que leí a la hora de comprarlo, pero me carga dos móviles igual de rápido que un cargador enchufado a la red (cargador no de carga rápida). Con lo cual me doy por contento ya que me sirve para lo que quiero.

Rugged, well designed and practical to use. What more to ask?

Charged my phone fully in under 2 hours in full sun
