About this item

  • Upgraded Triple USB Port: Each maximum output is 5V/3A and the total maximum current is at 5V/4.8A. BigBlue 28w solar charger allows you to charge multiple devices at once (Note: if one device requires a large current, the other two devices may not be charged). The built-in smart charging technology can provide optimal and 100% safe charging in direct sunlight
  • Used High-quality Solar Cell: The solar cells BigBlue adopted improve the solar charger’s durability by reducing heat buildup, making them more robust and less prone to damage, which extends their lifespan. Without metal lines on the front, these cells capture more sunlight, enhancing electricity generation and providing a sleek, modern design.
  • Higher Solar Conversion: Upgraded solar panels convert up to 25.4% of solar power into free energy in enough sunlight, which is the most durable panels at present, standing up to elements and wear and tear better than conventional panels. BigBlue uses a special polymer surface to protect solar panels from occasional rain or wet fog ( The junction box is not waterproof)
  • Portable Camping Solar Charger: With a folded size of 11× 6×1.4in and a lightweight (1.5 lbs) design, it is compact and light enough to fit into any camping backpack or hiking daypack. It is also a must-have for stashing in an emergency kit. BigBlue solar phone charger is a great option if you’re taking an extended camping trip or traveling somewhere with an unreliable power grid
  • Wide Compatibility: BigBlue USB solar charger offers a tiny power plant that can generate power for your phone (Android and Apple), power bank, speakers, and other small electronics to keep them charged when the sun is out (Note: we don't provide the lightning cable for Apple devices). Our portable solar charger can't store electricity and can't charge laptops and power station
  • Package & Support: You will get a BigBlue 28W Solar Panel Charger, a 50cm USB-A to USB-C Cable, four Carabiners, a User Manual and our friendly customer service. Note: Any clouds, the angle toward sunlight, operating temperature and sunlight intensity will affect the real output, we don't suggest you use this foldable solar panel inside of a window or windscreen

    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), and an expansive but lightweight array of panels to catch every last ray of sunlight. 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

    How to Use Your Solar Panel

    1. Place the solar panels in direct sunlight (full expansion required). For windows: Hang outdoors (never behind glass – blocks 25% sunlight!).
    2. Connect your device (phone, power bank) to the USB port of the solar charger. Charging starts instantly – no buttons!
    3. Note: This solar panel charger does not have a built-in battery and cannot store electricity - It does not function at night or in low-light conditions.

    Best Performance Tips

    ✔️ Keep the solar panel stable, clean, and shaded-free during use.

    Overheat warning:

    ✔️ Place your phone or power bank in shade (e.g., under trees) while charging

    High-quality Solar cells

    ✔️ Reducing heat buildup, making solar panel charger more robust and less prone to damage, which extends their lifespan. Without metal lines on the front, these cells capture more sunlight, enhancing electricity generation and providing a sleek, modern design.

    The maximum output of each port is 5V/3A, BUT the real outputs are related to the sunlight intensity, temperature, angle, shadow, etc.

    Customers say

    Customers find the solar charger works surprisingly well and appreciate its compact size that fits comfortably in backpacks. Moreover, the device keeps electronics powered up, is well-made, and customers consider it worth the money. However, the charging rate receives mixed feedback - while some report quick charging from 25% to 80%, others say it struggles to charge at all. Additionally, sunlight level is also mixed, with some customers noting it needs full direct sun while others mention it works with indirect sunlight through windows.

    Pretty awesome and well made for the price!
    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!

      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.

      Bought one of these in 2019 for a sailing trip in the Caribbean on which this solar panel (and it’s twin) we’re heavily used for 3 weeks to charge our various devices. It worked very well (even draw a little power on cloudy days) and kept us free of battery anxiety for weeks. We never had to use the boat’s power to charge our non-essential electronics, which very became important during our voyage.

      We found the trick was to use the solar panel to charge a power brick, then we’d charge our phone / ipad / cameras / whatever from that brick later (usually overnight). We used the provided carabiners to clip the panels to the awning and then we harvested the sunlight.

      My only complaint is the pocket in my model (for sale here) closes with a small strip of Velcro. You have to be very confident that your power brick / device is secure enough in the pocket to not fall out (no problem if you’re using the solar panel on the ground, but there was a risk on a boat!).

      The opening to the pocket is on the bottom, so if you clip the panel to a vertical surface (like your backpack), the thing you are trying to charge will likely fall out of the pocket. I went for a hike with the solar panel unfurled and clipped to my backpack, and had to keep the power brick / phone either in my backpack, or in my pants pocket while it was tethered to the solar panel via charging cable. It was an ok workaround.

      My friend brought her solar panel on the trip—also Big Blue, exact same size and specs—but her pocket closed with a zipper. Highly recommend that kind of closure if you intend to be actively moving (hiking / biking / sailing) with your solar panel!

      Overall, given how we needed to conserve power on the boat, this panel was an essential tool on our trip that we relied on every day for weeks, and it delivered!

      This worked beautifully from a southwest window in my home. I hung it in the window and it charged my phone and a portable charger quickly (I don't remember how long but I remember being surprised that it wasn't multiple hours, it was fast). 5-stars because I learned that this product works indoors!

      I have bought other smaller voltage solar chargers that claim to charge an iPad and smart phones. They charge phones very well, but do not have the ‘pure’ electrical charge needed for an iPad. This one however does. It looks well built and seems to be made with quality.

      This works pretty well and charges faster than some of the other solar panel chargers I’ve bought in the past. It even works during cloudy weather.

      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。

      I was skeptical when a lot of reviews said these don't work great in cloud but honestly this still generates power even under partial shade from a tree. Would recommend using your own cord to run to your phone/battery so that can sit in the shade and not overheat. Very happy with the size, perfect for overnight hikes

      Quality product. Easy to use. I get 2A current a sunny winter day in the middle of Sweden. Light cloudy and I am down to 1.5A. A medium cloudy day about 1A. That means that I should get 3A in the summer and promised 4A further south. Not bad. Everyone should have one of these at home. Highly recommended.

      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

      Le produit est d'une conception qualitative, et il est parfaitement fonctionnel.
      Parfait pour du camping, vous y branchez votre powerbank le matin, vous profitez de votre journée, et vous revenez le soir avec une powerbank pleine pour charger votre téléphone durant la nuit ! Prévoyez une powerbank de 10000mah (+ ne servirait à rien, car le panneau n'est pas assez puissant et vous êtes soumis aux conditions météo, - risquerait de vous faire perdre de la charge les jours de beau temps, qui permettrait de compenser les jours pluvieux)
      Je recommande ! (Pour un seul téléphone et batterie externe)
      De plus, il se range parfaitement dans un sac à dos.
