The Best Portable Solar Charger Reviewed by Wirecutter

” The BigBlue 28W USB Solar Charger produces the most power of any portable solar charger we’ve tested, and it has unique features that make it more versatile and durable, including three output ports (versus two on most other chargers), a weatherproof port protector, and an expansive but lightweight array of panels to catch every last ray of sunlight. Although other models come close to matching it in terms of power, the BigBlue is also smaller and lighter than other options with similar output, so it can more easily fit into a camping backpack, hiking daypack, or emergency kit.” — By Wirecutter Editor

    This worked better than I expected. My phone has a crappy battery and I recently went hiking in Zion National Park. We spend the entire day without power and at the end of it I had a well charged phone.It works best in good lighting of course. Overcast and shadows ruin it’s power output. It won’t work from just home lights, I tried haha =)My phone charges surprisingly fast. Even when a second phone is attached. I was able to take all the photos I wanted with no issues!I personally strapped mine to my camelback and used some mini bungees to do that. There are loops on the sides that make it easy to strap it to a backpack.Only downside I can think of is that the plastic coating gets a little scratched from rocks or plants, but it’s only cosmetic. It still looks great and works like a champ. I will be using this thing all summer, if anything changes I will update. I consider this a great buy!

    Charges tablets and smart phones fast in direct sunlight, much faster than my previous Goal Zero. It doesn’t have a battery pack to store energy though, so I bought a separate charger/external battery pack to use with it. Usually leave it on my car dash and charge the battery pack (RAVPower 22000mAh 5.8A Output 3-Port) so when i get back to the car I’ve got power waiting for me even if it’s already dark. Great buy.

    A lot of people complain about the charge times or it not working. First it’s a solar panel, it’s not going to charge as fast as it would plugged into your car or wall. Second it works best when it is outside in direct sunlight, not behind glass, not in the shade, not in cloudy weather, IN DIRECT SUNLIGHT. It will charge if it’s not in direct sunlight, but much slower. Also it’s going to take longer to charge if you’re using your phone while charging. The more you plug into it, the longer it will take to charge everything. It also doesn’t help if you’re using a 12ft long cable. So keep in mind when buying this, direct sunlight, turn off the device you’re charging, charge 1 device at a time when possible, and use the shortest cable possible.It’s very useful to have. Good for camping, hiking, hunting, survival, emergency preparedness, or just being environmentally conscious. If there’s a reason why you can’t charge your phone from an outlet, this is perfect. The size is about that of two tablets/iPads stacked on top of each other or a small laptop when folded up. And about 3 or 4 tablets/iPads side by side when opened up. It came with some carabiners so you can attach it to your backpack, tent, a chain link fence or just about anything that would help face it in direct sunlight. It also has a little indicator light where you plug your USB cable into that lets you know if you are getting power, the brighter the light, the more power you’re getting.As long as you keep those few things in mind this solar panel is effective and super simple to use.

    I’ve tried a 15w and 21w USB solar charger. Seattle is cloudy all the time, so the first two were unusable. But this one can deliver about 4-5 watts in the omnipresent cloudy northwest gloom.This charger also has a neat feature where if it doesn’t detect any current draw, it shuts off and restarts every few seconds. This allows a clean restart if a cloud or something blocks the sun momentarily. Older solar chargers lacked this function.This unit is large, but it works well.

    Keep in mind that this is supposed to be in direct sun, not inside the house or car. It is best to leave it to charge a portable battery and then use the battery to charge your devices. It did charge my battery and phone at the same time. But it took a while. Still a great buy

    Right off the bat, I’m going to start off by saying that this is NOT a perfect product. If you’re looking for a renewable energy source solution for any kind of practical or NBC prepping, and you think you’re going to find it for under $80, I would suggest maybe adjusting your expectations to something more reasonable and realistic.Despite all that, however, for the price, size and weight of this item, it’s an incredible camping and survival tool. Instead of carrying those extra pounds in batteries, you can just carry 4-8 18650s or AAs, and rotate their recharge cycles throughout your trip. If you ever get stranded or trapped because of some environmental condition, at least you know there is no out limit on you having the ability to have a source of electricity. So, your radio, beacon, gps, LED light, etc. have a much higher likelihood of being useful to you days beyond your planned trip.At 28W with three (3) USB charging ports, it’s probably the best value for the price (within this product category). It’s worth noting that this product is NOT 100% waterproof. The weatherproof sleeve over the solar cells is what keeps the functioning components from making contact with water. The USB charging area is protected only by a water resistant sleeve. My recommendation is to use your paracord to line panels 2&3 completely horizontally, panel 1 on a 45 degree upward slope, panel 4 on a 45 degree downward slope, and the sleeve protecting the USB completely vertically (facing down). This way, you can optimize the efficiency of whatever sunlight is available, and protect the USB connections (and the entire unit) from water damage. You can then try to cover your devices or chargers where the male part of the USB cable connects with a plastic bag.

    I go camping a lot with a bunch of kids and you know they can’t live without their smartphones/tablets. I use a small portable lipo battery pack but that is only good for a few phone recharges and only one tablet charge. So I decided to try solar panels, did a little research and decided to go with the 4 panel design for max power (28 watts). I tested it on my Apple IPhone 6 plus and it went from half charged to nearly full charge in 30 mins. It can charge three separate devices at one time, but remember it only outputs 28 watts so the more devices the less power each device will get which extends the charging time. The panel works best in direct sunlight just remember not to leave your device in the direct sunlight as it may overheat and be damaged. I usually place the panel on top of the park bench, hang the charging wires down below the table and place the devices that need to be charged under the table out of the direct sunlight.

     BigBlue 5V 28W Foldable Outdoor Solar Powered Charger With SunPower Solar Panels 3 USB PortsI often am out backpacking and hiking during the summer months. I carry rechargeable batteries, but find myself using them up before I return. I found this solar panel and wanted to try it for recharging my devices while out on the trail. Pros:    • 4 panels • 3 USB Ports • Loops for Caribiners • 4 Caribiners included • Short Micro USB Cable included • Charges even in low sunlight • Does not drain battery when out of sunlight  Cons:  NoneThis solar charger is very well made. All the stitching is tight. The velcro sticks very well. The panels are water resistant and scratch resistant. It folds up very compact. The overall weight is not very much compared to a large battery. The USB ports are easily accessible. There are three of them. The pouch is very convenient to store a phone or battery in while charging. Three devices can be charged at one time. When using a solar panel, I will often charge my batteries, then charge my phone. The power output on a partially sunny day was very impressive. Nearly 5 volts. As the sun came out more, it pegged the 5v mark. Amps increased as well. The meter I used to measure Voltage and amps was not very readable in the sunlight. But it was measuring very good voltage and amps. Overall, I am very pleased with this solar panel.

    I recently purchased the BigBlue 5V 28W folding solar panel for recharging phones, tablets, and other USB items. I deliberately ran my LG5 smartphone, Samsung 12.2 inch tablet, and my portable power bank down to near 0 and hooked all three of them up on a sunny, clear day. I put them on the picnic table laying flat in full sun and came back every few hours to see what their power levels were. By 7.5 hours all three devices were full capacity power and I couldn’t be happier. My tablet is a slow charger and the power bank holds an enormous amount of power and can jump a dead car battery. I am positive that my fast charging phone would be as fast or close to the speed of charging with electricity had I plugged it in to the panel alone. I keep this in my bug out bag for any type of emergency situation including our frequent local power outages. While it is a little bit heavy by backpacking standards at 1.3 pounds, the workmanship and function far outweigh a few extra ounces for a 28 watt panel. Extremely well made, a fast charger, and a reasonable price.

    Very satisfied with this product. Use it every day on Denali. This means it was quite exposed to different elements: I had to stuff it in my backpack with other things, rain/snow drizzled on it, very cold at night, etc.. Never stopped working. Given the three outlets more people of our expedition came to me to use my charger since it was the most reliable one. The holes on the edges and the carabiners that come with it make it very easy to attach it in a way that it can soak up a lot of sun (see picture).
