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

bought this and a competitor to allow free charging and usb power for phones, radieo, flash lights and walkie talkies both at home and "camping out" in SHTF situations or bugging out, recharge power is vital. so how did they do? I ran 2 mobiles down to 10%, placed this 14 w and the competitor 15 w in the sun and connected the phones, after 4 hrs this had charged to 85% while the other only 40% after 6 hours this reached full as opposed to 70%. next i tried some new rechargable batteries, AA, This took 3hrs while the other took 5 hrs. this is fairly light and easy to clean. at the same time i charged my phone I also charged a power bank, making the phone chargin more impressive. it also has a pocker for the power brick. Only negative being the carabinas, so thin they gave no confidence in hanging the panels and attached power bank, so I use my own heavy duty ones. pay the extra tenner for this, it will pay for itself very quickly.

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.

While cycle touring I use my phone extensively for mapping, navigation and ebooks, so keeping it charged up is high priority. I had low expectations for the 14W panel (I'd tried solar panels previously without much success) but was delighted to be able to charge an external 3200mAH battery while riding, which I then used to charge my iPhone SE (1,821mAh battery) during the night. The amount of charge obviously depended on the weather conditions - in late June the panel charged my backup battery even on bright overcast days (i.e. not blue skies) enough to fully charge my phone. If the sun was fully shining the backup battery would be fully charged in about 6 hours, with the panel draped over my panniers while riding. All in all very impressed. After a week of riding in mostly good weather I didn't need to plug in my phone to charge it once. One improvement would be to have attachment hoops in the middle of the unfolded panels to allow the panels to be fixed centrally.

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.

Wat een geweldig product. In de zon krijg je natuurlijk niet de volle 14w, maar dit zonnepaneeltje wekt ook stroom op bij bewolking. Zover heb ik er 8w uitgekregen wat al geweldig is voor mij (ik heb hem maar 1x getest, dit is wel in de zon) wat genoeg is voor mij omdat mijn smartphone laadt rond de 7.5w aangezien ik alleen gebruik maak van normaal, en niet snelladen. Hiermee is mijn smartphone in ongeveer 1.5 uur geladen. Echte aanrader!

High quality and durability, a must for offroad or outside camping for charging batteries. Tried and tested.
