Stay Connected with the Sunferno Portable Solar Panel and Battery Pack

If there is one thing I know for sure, it is that prepper and survival types are in love with solar.  What is not to like?  With solar devices, we can use the power of the sun to give us light and to energize our devices, large or small. Whereas using the sun to power a refrigerator or laptop takes some doing, providing power to a phone, tablet, Kindle or other eBook reader is not only easy, but downright inexpensive.

Each month, it seems, I learn of a new device that can be used for this purpose.  It just keeps getting better and better.

Sunferno Portable Solar Panel and Battery Pack - Backdoor Survival

Today I would like to tell you about the Sunferno Portable Solar Panel and Rechargeable Battery Pack.  For simplicity, I call it the Sunferno and with its small, lightweight form factor, it is a fantastic addition to your preps, or as in my case, my EDC.

The Sunferno Portable Solar Panel

I know that I am repeating myself but when it comes to Every Day Carry, size and weight matters.  Size matters because your EDC (or daypack or handbag) should be as unobtrusive and compact as possible.  And weight?  That is self-explanatory.  Carting around a 20 pound pack of essentials everywhere is going to wear you down. For that reason alone, I love the Sunferno.  It weighs in at mere 6 ounces which is just about perfect. Sunferno Portable Solar Panel and Battery Pack - Backdoor Survival

The real key to liking something, however, is how it works.  Let me explain.

First of all, to best utilize the Sunferno, you need to charge up the embedded battery pack.  You can use the included USB cable plugged into a wall adapter.  I used the one that came with my iPhone but any similar type of adapter will work.  You can also use the USB port on your computer or, if you have one, in your vehicle. The charging status is noted by a series of blue lights as shown in the photo below.  When all 4 lights are lit up, the battery pack is fully charged. Also in the picture is my phone which is currently being charged by the battery pack.  I have performed the same operation with both my iPad and my Kindle and they are charge up fine.

So here is the deal.  When the energy stored in the battery pack is used up, you can set the Sunferno out in the sunlight to charge it up again.  You will know that it is charging because the first LED will be green.  At that point, you can plug in your device and either charge it up or use it. It is as simple as that.  But there is more!

Other Useful Features of the Sunferno

There are actually two USB ports on the Sunferno so you can charge two external devices at once.  The only limitation is that they do not exceed 5V each which for small electronics and tablets, is not a problem. Another cool feature is that it has an integrated flashlight.

You know me and flashlights – one is none and two is marginal.  I need at least three flashlights with me to feel adequately prepared.  To turn the LED torch style lamp on or off, all you need to do is hold the on/off button for 2 seconds.  Simple. Finally, the charger starts automatically after connecting a device.  It takes about two seconds to recognize and identify the connected device using smart charging technology but then you are good to go.

There is one thing I found confusing until I understood how it worked. (A hit tip to customer support who explained it to me.) The solar panel will only charge the internal battery up to 25% or its overall capacity (or the first 2000mAh of its total capacity of 5000mAH).  This is utilize the solar panel portion of the battery pack an emergency backup charger for those times when no other power source is available.

The Final Word

As I mentioned at the beginning, learning to harness the power of the sun is an important part of preparedness.  I am thrilled to find that more and more companies are developing and selling solar devices at a reasonable cost. It is my opinion that along with solar lighting, having some way to power electronic devices should be on everyone’s bucket list.  To that end, the Sunferno satisfies both requirements, and at an extremely reasonable price, especially with the BDS25OFF discount code. It is my understanding the the discount is good for a limited number of uses but that being said, I hope you will also enter the giveaway.  This is a good one!

  1. I read most of my ebooks on my kindle fire. Every once in a while, I use my computer. If I am seriously desperate, I will read them on my iphone.

  2. I have about a billion prepper books in my kindle app. I usually read on my iPad, but love that my phone can be used in a pinch.

  3. I read my books on a kindle. Love it. This would be a neat addition to my preps, if my wife doesn’t get to it first!!!

  4. New to the prep. So hlad i discovered your site. You truly give the best information without all the unnecessary info. Thank you so much for guiding us new ones through our preparations

  5. I use my Kindle for reading and any I want to keep in a device so I don’t have to access the internet I put on my laptop. This would be a wonderful addition to my preps. Thanks so much for the opportunity to win it. Good luck everyone.

  6. I read ebooks on my desktop with the kindle app or a pdf reader (if the book is in pdf format). I also have two android devices with the kindle app that I read books on. Then again, sometimes, if the book is short enough, I’ll print it out and read the hard copy!

  7. My husband has a Nook and I have a Kindle Fire–which needs to be charged quite often, so this would be a great gadget for that!

  8. Another great giveaway! Thank you!! I am a Kindle addict and read daily. I take my older Kindle with me always, use my Kindle with backlight at night (helps when you live in buggy Arizona) and also play with my Kindle Fire. I have a separate regular Kindle loaded with prepper books. This solar charger would be awesome. I would be lost if I couldn’t charge my books. Love them all!

  9. I read most on my Kindle (the original). I have an HD Kindle but I think my battery is stronger/longer lasting in the older (1st gen) one.

  10. Did you run it down and try to get that 25% solar charge? I have seen many of these devices that sound good but the solar charge always comes up lacking. Seems the ‘theoretical’ charge time/capacity just doesn’t stand up to the real world and many need days to charge…
    Still looking for something good 😉

    1. Yes I did. I had some pictures of the green LED on then off again after it was charged using the solar panel. There was too much glare to use them; taking photos is not my thing – lousy at it.

      Afterward, there was enough stored power to charge my phone up from 50%.

  11. It is an android tablet, Nextbook. I also just sit at the old desk top in the dining room so I can supervise home school, also. 🙂

  12. I just knew there was a reason why I hadn’t filled this one space in my EDC. Considering the size in relation to your phone, now I know. 🙂 BTW: I have a main EDC and smaller pacs which slip in depending on where I’m going. This would be in the main carry.

  13. I generally try to avoid eBooks and get the hard copy instead. For the few books that I’ve got that only come as an eBook I use my laptop with a kindle app.

  14. My husbands kindle. Although I don’t get much of a chance to read anything on it because he’s always reading on it! lol

  15. I only have an iPhone currently, so I don’t read books electronically. I am going to purchase a device soon, but still trying to decide what I want.

  16. Uh oh. I’m way behind. No Kindle, no ebooks. I would like to read books on my iPhone. But Amazon will not sell them to me. I do have an app for books on my phone. But I think I have to boot up my laptop, which I almost never do, and then do something, no idea what, to my Amazon account.

    A question. In the event the SHTF, what could be physically stored on my phone, in the way of books or movies, so that with a solar charger I could use my phone for something even without Internet?

    1. You need to download the Kindle for iPhone app from the app store. Once you do, when you make a purchase (or get a free at the moment eBook), you can have it directed to your phone.

      The amount of “data” stored on your phone is dependent upon the size of it’s memory. I put a lot of music and audiobooks on mine and still have tons of space for books and apps. Music and videos take up a lot of memory. Books not so much.

      I have an old Sony reader that still works great but the Kindle Paperwhite is the bee’s knees due to its integrated way of being readable in the dark. Tablets take a lot more power than standalone readers.

      Why do you say Amazon won’t sell you eBooks? Perhaps it is because you do not have a Kindle app installed anywhere. I gave the app on my iPads, laptops, and phone. Everywhere. They all sync. Plus, I send library books to the app. I should wrap up the article I have been working on about eBooks. Honestly. I need to do that.

  17. I read my ebooks with my iPod Touch. It fits easily into my pocket and I can pull it out whenever I have a few spare minutes to read.

  18. I am an avid reader so have Nook. I have kindle app on my phone and tablet and nook app on my iPad and phone. Just in case! You never know!

  19. I use my phone, Nook or super cheap tablet. There are tons of books saved which is handy while waiting for lessons, appointments or just free time.

  20. I read my ebooks on my laptop PC, my Kindle Fire and my Nook, which I really like the most since it’s simple and light weight.

  21. I read on my Kindle, IPAD and phone, which ever is charged up the most. This item would be ideal to have in a BOB.
    Thanks for all the great useful give away.

  22. I read them from my laptop. It would be nice to find a nifty little charger like this that would work for my laptop.

  23. I have both a Kindle Fire and a Samsung Galaxy tab that I read with. All depends on where I am, home or elsewhere. I usually have one or the other. My app syncs so I can stay up to date, no matter what I read or where.

  24. I have a Samsung Galaxy Tablet that I downloaded the android app for Kindle. I’ve downloaded quite a few of the books you recommend.

  25. I have both a Kindle, and use the Kindle app for iPhone, sometimes also use the Apple iBooks app as well.

  26. I do not read ebooks, not even on my computer; I don’t even have a cell phone. I read paper books and celebrate my library card. I am more of a Luddite than a member of the “connected” society.

  27. Don’t have an E-Reader I buy books or use the computer. Also I tried to confirm that I subscribe but the little box won’t let me type my EM addy in it. Just thought you’d like to know, every thing else works
    Thank you for the give-a-ways.

  28. I have a Nook that I bought about five years ago that travels to work with me to read on my lunch break, and an iPad with both the Nook and Kindle apps on it that I use everywhere else.

  29. I usually use my phone (Samsung Galaxie) for reading ebooks. I listen to audio books a lot more often then I read ebooks though.

  30. I use my Kindle Fire to read most things, but I also use my Samsung Galaxy S5. Love Backdoor Survival.

  31. I have a first generation Kindle as well as two Kindle Fire 7 HD. I also have the Kindle reading app installed on my Chromebook and laptop. Having a back up power supply would be amazing! The thought of being without my e-books is an unpleasant one, to say the least.

    1. Please try again. I am not sure why this problem occurs every once in awhile but everything is working fine at my end. I am going to contact Rafflecopter support about this.

  32. I have been looking at solar chargers to buy, but if I can get one for free why not try? Thanks for the opportunity!

  33. What a great tool to have. The SUNFERNO Portable Solar Panel and Battery Pack should be a welcomed addition for most everyone’s preparedness “tool chest”. Thank you, Gaye, for your very timely and informative website. Thank you, SUNFERNO, for having such a great product.

  34. I read ebooks on my HP Slate7. My Galaxy GrandPrime phone has a 5 inch display and is bright, but not quite big enough to enjoy ebooks on.

  35. I travel a good deal so I read using a generic e-reader, Samsung Galaxy S3, laptop and hard copy. This device should work just fine for me.

  36. I was camping with my two sons at a recent cub scout trip and saw a similar product that one of the other den parents were using. I asked if I could plug my iPhone in and of course he said yes. The one I used was not this model, but the charge time was faster than I thought, the device was small (about pocket size) and very lightweight.

    This model looks to be similar and I would imagine performs equally as well. It would be great have around in areas where there is no power.

  37. Just ordered the SUNFERNO from Amazon and tried to use the BDS25OFF code. The code wasn’t allowed — said that it was expired. I was disappointed!

    1. I am furious with Sunferno for discontinuing the code before the agreed to period was over. I do apologize. The product is good but they really disappointed me in this regard.

      I feel very bad but this was not something I was aware of until after the fact and apparently Amazon will not let them re-instate the same discount code again. They plan on giving me a new discount code but I am not sue that will help in your case.
