BigBlue 30W Solar Panel with Fast Charging USB-A, PD 24W USB-C and DC Ports, IP68 Waterproof, Portable Folding Solar Charger Compatible with iPhone, iPad, Samsung, LG, Power Banks, Power Station etc

This is perfect if you don’t have access to electricity! My husband used this for his two week drill for his phone, watch, and AirPods. It does need to stay in the sunlight while charging so we recommend bringing something to cover your devices so they don’t overheat.

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!

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.

Buenos acabados y bajo peso

Charged iPhone 14 Pro from 37% to 100% in less than two hours in full sun

Best camping item!! I take multiple trips a year ranging from 7-10 days. I am able to keep my android phone, ecig, headlamp, lantern along with various other items fully charged the entire time. Several days will be overcast or rainy and I'm still able to get a charge. I've been using this for 2 years now and it is a must have in my supplies!!

Company claimed that it is 28 watt. But i checked it with tester, single port and dual port. Also one panel to four panels. On the single port it deliver 11 watt at noon and fully sunny day. It is ok because of usb limitation and dont wave quick charge or power delivery. But If i add second device then the other device down to 4 watt. I mean total wattage still about 11 watt.The other problem is if a bit shade then the wattage going down and never come up until you unplug and plug again.People who on the comments only talking about “ohhh it is charging very fast.” But how much watt? I think they are comparing to 5 watt wall charger. If so yes it is faster than it. Really funny. Because most of phones and powerbanks supports fast charhing. For example you can’t charge 26k mah powerbank in full day. Needs about 2 days at least.It writes it has Sunpower cell but not different than other monocrystaline products. I think it is not high efficiency one. If not look at to the sun directly then half power. I mean about 4-5 watt. I’m totally frustrated! Because I searched a lot,read lots of comments videos then I bought. I think many of them is promotion.All panels connected parallel. It is not bad actually. It can deliver a bit power Even one panel is open. BUT each panel deliver 3.5-4 watt!!! as my tester. 4X4=16 Watts on fully sunny day. Im not talking about one usb output. Total output is about 16 watt. I hate lier sellers.Pros:-very light and small. 600 gr. Can good for backpacking or small devices. Such as old phones, lights etc.-all panels connected by parallel so you one panel is closed then will continue to work. With less power ofcourse:)- a bit flexable and durable.Cons:- not 28 watt!!!. 11-16 watt in fully sunny day.- if connecting to 2 device then power down because sharing the source.- solar controller in the bag looks weak for hot days.- there is no Quick Charge( we are in 21. Century) it is only 5 volt.- there is no type-c or PD.-need to dirrct sun for enough power. If not your phone will open close open close …-
