BigBlue 14W Solar Panels with USB(5V/2.4A), IPX4 Waterproof, Folding Portable Solar Phone Charger Compatible with iPhone, Tablet, Samsung LG etc

I love my portable camping solar panels. Have taken them on several hikes in the UK and France and they are great for keeping my devices topped up with power. The fabric is durable and the design is simple to use with two USB ports. It is worth noting that to get the maximum power output you need to use both ports. It will only provide a maximum of 2.0 per port. If works well in both direct sunlight and shade, although the power drops off a lot in the shade. For best output I prop the panels so they are at 90 degrees to the sun if it isn’t directly overhead. I also pair it with a portable battery pack, which I then charge my other devices with. As more devices switch to USB C, I would look for panel with high output on a single port to charge the battery pack faster, but this model will keep an iPhone topped up. I also like the display so that I can adjust the position to maximise output.

Purchased to add versatility to my off-grid/disaster kit. I wasn't expecting much and initially I got very mixed results. You do need to work with this solar charger to get to know what it can do and what it'll do badly. 1. The bad - On intermittent charging days (good sun mixed with fleeting clouds) don't try charging a device ie phone. Mine went from 75% charged (looking to a top up) to 40%. It was the first day I used it nearly returned it until I worked out why. Every time the charging cut in or out, the phone was waking up to vibrate/alert resulting in a net drain. Use a powerbank and that'll work a bit better. 2. The good - On a sunny (northern UK) day in early spring, I've got about 1000mA per hour into a powerbank consistently. Which is pretty good as I wasn't trying to optimise it. 3. The average - On a cloudy day, you're not going to get much or at least, for me, where I am, zip. To be honest, that's no worse than expected. Is this a good device? Yes. It seems to be well made and certainly it works. It is not 'wallet sized' unless you have a truly well stuffed wallet!! Joking aside, it will fit in a trouser cargo pocket (tight squeeze maybe) but it is compact for what it does. Overall, considering that it's the price of three or four packs of AA batteries, buy one quick before they put the price up!

I like the overall design and the build quality is good but the USB-A port is too exposed to potential scratches and damage, so extra handling care is required. The stitched on clip pouch beside the USB-A port is sewn on well, sturdy and practical, many small things can be placed inside, like a power bank, charging cables and a mobile phone etc. I have 2 Anker power banks, the 10000 and 20100, each fit inside the clip pouch fine but I found the 20100 feels more secure as you have to stretch the elasticated strap over the top of it to securely fasten. As for charging, I was very pleased by the performance of the solar charger, BigBlue claims it is 14W but my own opinion is that the device is more closer to or actually 12W, as 5V x 2.4amp = 12W (5 x 2.4). This calculation I've demonstrated may not be entirely accurate as I wasn't able to fully test the amps and watts input/output of the solar charger first. This being said however, the solar charger performed better than I expected, on a clear sunny day I was able to charge my Anker 10000 from 25% to 50%, that's 2500mah to 5000mah in 1 hour 20 minutes. Even on a fully overcast day with no sun and either white or light grey clouds the solar charger still worked, albeit the amps and watts would have been heavily reduced by probably half or more; this is still impressive considering you're not only restricted to just using the device on a clear sunny or partly sunny day, and can charge your small electronic devices in more variable weather conditions. I put the solar charger through it's paces and tested it's IPX4 waterproof rating, didn't really want to get the device wet but felt I needed to test BigBlue's claim properly and thoroughly to see if they were right. Using my Anker 10000 power bank and during a 20 minute light to medium continuous shower, the solar charger stopped working because the clouds became very dark grey, the rain peltered the device, soaked each one of the 4 solar panels and the water partly seeped into all the front of the solar charger's blue stitched fabric, but not the back. After the rain had stopped and the the clouds turned from dark to light grey the solar charger sprang into life again and the blue light on my Anker 10000 power bank began flashing. (Please refer to my photos for an accurate visual reference) You get a 65cm USB-A to USB-C cable and 2 carabiner clips on the box which are nice extras, both serve a practical use and the quality of them is decent. I purchased the solar charger when Amazon had a sale on, so got the device for £40 which I believe is a more realistic and fair price than it's RRP of nearly £60. To maximise quick charging capabilities of your electronics, use at least 2.4 amp cables as this is the maximum USB output of the device. On a cloudless day you can get a relatively steady 2300 - 2400mAh, as long as you keep the solar charger directly facing the sun and at the right vertical angle. Would I recommend this solar charger... absolutely, as long as you look after the USB-A port and handle the device with care it should give you years of solid quick charging pleasure.

Bought this after a smaller one failed to charge my phone. I love that it has an ammeter so it shows the charge going in and works in shady conditions (but at a lower charging rate). Very robust and worked after getting caught out in rain. This meant I was able to keep a mobile phone fully charged without any other electrical means for a week at the IoM TT races

Seems to lack the circuit to prevent device discharge if so much as the shadow of a sparrow crosses the panels. Bought as a backup for going to a festival. Left a powerbank plugged into this on a very sunny day (in Devon, SW England), and when I got back that evening the powerbank had less charge than when I set it up in the morning. Tried this for a second and third day (weather mixed), until the powerbank was completely depleted. Upon returning home I tried again placing the panels in an upstairs SSE facing window on a clear bright sunny day and hooked up an old phone with 50% charge. If not attached to anything the phone would have lasted all day (being idle) but within 2hours it had shut down with a flat battery. I see no use for a solar panel which discharges devices in anything but ideal situations. Being slower than hoped I could have coped with, but actually having a negative effect makes this completely useless. I'm not going to sit next to it all day unplugging and re-plugging for every passing cloud, whilst panning the thing round to always face directly at the sun.

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 😊

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。

Fajna opcja, że panele rozkładają się na w dwa rzędy, przez co po złożeniu zajmują mało miejsca. Jednak z deklarowanych przez producenta 60 watów, panel maksymalnie osiąga 38 watów.

Halverwege september in Luxemburg haal ik midden op de dag nog 38W op via USB-C met dit paneel bij een helder blauwe lucht. Ik ben heel tevreden en positief verrast voor deze prijs! Hij vauwt ook mooi op, maar de standaard is te vlak voor Nederland en Luxemburg. Je moet hem iets meer schuin zetten voor optimale opbrengst

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.
