BigBlue 28W Solar Panel Charger with Dual USB-C and USB-A, Portable Solar Phone Charger for Camping, Hiking, Backpacking, Emergency Solar Charger for iPhone, iPad, Samsung Galaxy, Power Bank, GPS etc

Panneau test efficace pour recharger grâce au soleil des petits appareils électriques ou électronique : téléphone, batterie, rasoir électrique...Le meilleur panneau que j'ai commandé !Je recommande.

My intended use of this product is to maintain complete power independence for months-long, off-grid backpacking (thru-hiking). I've always laughed at the hikers who try to make things work with a single panel on top of their backpack, but the bigblue can work, under the right conditions.My electronics consist of generic bluetooth listening devices, a cell phone, a gps communications and tracking device, a rechargeable tracking watch, a rechargeable air mattress inflator, a rechargeable headlamp, and a 10,000 mAh power bank with dual charge inputs and a maximum recharge rate of 22W. Since the bigblue only delivers a maximum of 5V @ 2.4A to each of its 3 usb, connectors, it means you can only expect a maximum of 12W from each usb connector. Therefore, to obtain the maximum possible powerbank recharge rate from this setup, I needed a powerbank with 2 charge inputs. The only such one I could find in the 10k mAh range was the nitecore nb10000 gen 3. In theory, I could get 24W from 2 of the bigblue usb connectors, and I would be wasting a couple of watts on the nitecore, but in reality so far I have not gotten more than about 16-17W form the bigblue, as measured using an Anker Prime 27,650 power bank. That's in southern US and november sky, but I would not expect more than about 20-21W under perfect conditions, anyway.I have tested and determined that hanging the bigblue from the backpack is pretty much useless and not worth the effort. Also, it only delivers a trivial amount of power under heavy cloud conditions. It does deliver modest amounts of power when the sun is still fairly bright through a fully overcast sky. Under partly cloudy skies, with thicker clouds, the output falls off dramatically when the sun is blocked.The most workable solution that I have found is to pack up the bigblue in the morning, leaving it in the top of my pack. I'll take a 15 minute break mid-morning and quickly pull out the bigblue and connect the nitecore to 2 ports and my cell phone to the third port, providing the right sun conditions exist. The bigblue does not have a kickstand, and the panels flop around, so I find a long, straight stick and prop up the panels using a few bits of gear to prop the stick and panels up straight. The same process is repeated at lunch time for a 1 hour lunch break, and possibly another short break mid-afternoon. Using this approach, under the right conditions, I can fully recharge my phone from about 80% and I can recharge up to 2 bars out of 4 on my power bank. This is generally all I need, but I have not determined how long this setup would last with prolonged days of no adequate sun. I could probably last a week or so with careful use of electronics, but then I would be digging out of a power deficit for several days after. If the cloudy conditions persist, I would be forced off trail to recharge.I have also found that the bigblue can still deliver 3 watts or so folded up, with only one panel exposed to full mid-day sun and laying flat . This might work to charge low-power devices with the bigblue laying flat on top of the backback. It's always going to be important to make sure any means of securing the unit does not cast any shadow anywhere on the panel.My bigblue weighs 24-7/8 ounces. It's an awful lot to lug around. I think a lot of that weight is in the fabric, velcro closures and hanging grommets. I keep looking at the thing and wondering how much I could cut off. The 3 output connectors, with limit to 12 watts on each, is a pain when trying to find a suitable power bank that can recharge at a faster rate than 12 watts. Maybe 2 usb-c's, with no limitations, would work better? The weight and the connectors are my reason for 4 stars.So far, I have not tested for many days on trail, but it's looking possible. The implementation is not ideal, but I'm balancing that against having to go off trail and find an outlet.

太陽に当てても充電が出来ない！と思っていたら、私の勘違いで、蓄電する訳ではなく、太陽に当てながら充電をする物でした。レビューを入れたところ、親切に対応していただきました。星1→星5に変更しました。

I actually really like it,It's a moderate at 15 watts,I didn't realize this was the smaller wattage of the panels,I actually thought the color had something to do with the price.But what's important is,it works really well and better then I expected.It's enough to charge things moderatly fast, in good sun of course, it's Ultra lightweight,and I couldn't believe how small and well made this thing is!It has a special compartment/pocket to hold the phone or battery pack in place with a strap to keep the item from falling out while charging,And keeps the item out of the direct Sun.It's actually a lot fancier looking than I expected as well and the panels seem to be tough!This will be perfect for adventures in the woods!

I recieved the ild version of the product, not the same as the picture shown. Though very few changes in the updated one but its not right to cheat. Used very few times till now and satisfied with the quality and charging level. More can be said only after using it properly for a trek

Zusammengefasst ein top Produkt, womit ich nach knapp einem Jahr Verwendung vollstens zufrieden bin. Habe es für Festivals und Wanderungen gekauft nutze es aber regelmäßig und es funktioniert für Handys, Kopfhörer, Kleine Lichter, etc super. Preis-Leistung für mich ein Knaller. Wer meint mehr Strom produzieren zu können als es kostet... weiß ich nicht, dauert wenn Jahre... aber zum Wandern, etc. super, beim Fahrrad fahren ne powerbank dran, übern Rucksack werfen, alles wird voll, klar dauert es ca. doppelt so lange wie an der Steckdose, aber da sollte man denke ich mit rechnen. Besser als jede Solarpowerbank oder quatsch den ich vorab hatte.Bezugnahme zu 1 Sterne Bewertungen:Es gibt sicher Montagsmodelle, aber was man (leider generell immer häufiger) unter 1 Sterne Bewertungen findet sind gerade bei Technik so oft Bedienfehler und Unwissenheit, das ist unglaublich.Zu Bewertungen wie "geht nicht in Schatten" oder "Im Winter unbrauchbar" brauche ich nichts sagen. "In voller Sonne kaum Ladeleistung". WIKEL! Optimal sind 30-35° zur Sonne... die sich auch noch selbst bewegt... daher fiddel ich mir am Fenster, siehe Bild, immer mit einem Zollstock was zurecht und dann schwupps, doppelte Leistung, auch bei disigem Wetter oder leichten Wolken."Flackert nur und lädt nicht"Ich nutze auch gerne eine alte Powetbank mit nur 3000mAh weil diese nichts erwartet, selbst bei einer Anzeige von 0A am Pad lädt sie auch wenn es bewölkt ist, bei Wolken braucht dann aber selbst die locker 8+h, aber ist ja auch Solar, Solar braucht Sonne.Große Powerbanks erwarten teilweise min. 0,5A, habe ich das Pad im falschen Winkel in der Sonne, es schafft so nur 0,4A ich schließe eine Powerbank an, welche höhere Spannung erwartet: Startet der Ladevorgang, bricht ab wegen zu wenig Spannung, fängt an, bricht ab, ...... einfach mal ein Handy oder Kopfhörer oder ähnliches mit kleinem Akku zum testen nehmen, anschließen und mal das Pad bewegen und schauen wann was passiert. Generell unterschiedliche Powerbanks und Geräte verhalten sich teils auch anders an dem Pad, da kann das Pad aber auch wenig zu, liegt i.d.R. an den Geräten."In voller Sonne zeigt es 0 Ampere" - Klemm was dran, dann kann das Amperemeter auch die Ampere die abgenommen werden messen.. nichts angeschlossen, keine Anzeige..."Surface lädt nicht // Laptop lädt nicht"Das Ding ist mit 28Watt ausgewiesen, ein Surface Netzteil hat min. 44Watt, die neuen 60-127Watt... Grob informieren wäre schon gut bevor man andere Käufer abschreckt, findet man in 5sek heraus.... Ein Surface Go Modell schafft das Pad im voller Sonne vielleicht gerade so (24W).Sollte mein Pad doch noch nach Garantie auf einmal nur noch halbe Leistung bringen oder sonstiges Update ich euch, aber ich klicke auch gerne mal auf die 1Srerne Bewertungen und werde dann skeptisch und kaufe es ggf nicht, daher hier mal ein bisschen Feedback aus meiner Sicht nach einem Jahr dazu.Liebe Grüße

When I first purchased this portable solar panel, I was skeptical about its capabilities. To be honest, I didn’t anticipate its impressive performance. Let’s begin with the build quality. The manufacturer has done an excellent job with the design and construction. The foldable design makes it incredibly portable, and the panels themselves feel sturdy and well-made, not cheap at all. I appreciate that it comes with carabiners, which makes attaching it to a backpack or hanging it easy and convenient.Since I’m always on the go and carry a lot of tech, I’m constantly in need of extra power for my gadgets. I paired this solar panel with a NESTOUT 15000N portable outdoor battery, and they work seamlessly together for my needs. The solar panels keep my battery charged, and I use the power from the battery to quickly charge my devices. The USB-C ports and USB-A port works great without any problems and allows me to connect to my devices quickly without any delay.Now, don’t expect these small panels to charge devices rapidly. They do the job, and so far, with the sunlight I’ve been exposed to daily, they’ve worked flawlessly. I highly recommend this product. Considering its limitations and my use case, I believe it was a wise investment. I’ve also recommended it to several friends who work outdoors, and they’re equally impressed with its performance.

Contrairement à certains commentaires, je trouve que ces panneaux solaires depliants rechargent très bien, je peux avoir une charge à 100 %/joir sur une batterie de 10000 a ou téléphone. Je suis toujours très etonnée de constater qu'il charge, biensûr moindrement, en temps un peu couvert. C'est le deuxième que je rachète, je profite toujours des promos. Il faut savoir qu'il rechargera moins sur un sac à dos car on est susceptible de changer d'orientation souvent, mais en fixe il est impeccable.
