With our reliance on portable electronics, a huge concern is what will we do when the power is out and our batteries are dead?

This is true not only for our phones which provide a vital link to the outside world, but for our tablets, and electronic readers, too.  Think about it.  We all have hundreds if not thousands of documents that will help us muddle through if the grid goes down.  Barring printing them out and setting up a massive library system, we will be stuck unless we have some way to power up our gizmos.

Enter the SunJack Portable Solar Charger which will not only charge up and power your devices, it will also store reserve power in a battery pack.

Sunjack Solar Charger Review

Today I am posting a brief review plus, as always, am giving you an opportunity to win the SunJack Portable Solar Charger and the companion Camplight LED Bulb for free.  More about the giveaway in a moment because first I want to tell you about the SunJack itself and how it works.

SunJack Portable Solar Charger – The Basics

The SunJack consists of a fold-up set of solar charging panels nicely packaged in a compact case that has a zippered mesh pocket for holding the included battery, charging cable, and two USB ports.  Closed up, it measures about 9” by 6.5” which is smaller than my iPad.  It comes with an external battery pack that once charged, can be carried in a pocket or backpack to provide portable power on the go.  Or, if you like, you can connect your devices directly to the panels themselves.

This means that with a fully charged battery pack and some sun, you could effectively power or charge four devices at once, 2 on the battery and 2 on a direct connection to the panel.  I can not imagine the need to charge more devices than 4 but extra battery packs are available for a very reasonable price.

As you can see in the photo below, the SunJack comes with built-in hooks as well as some carabiner clips so that you can hang the SunJack to face the sun in the most optimal manner.  I hung the panel vertically but there are hooks on all sides so you can choose the method that works best for you.

So why am I so crazy about the SunJack?  One of the reasons is that the instructions were a single-sided sheet of paper measuring 8.5” x 5.5”.  It was titled “Quick Start Guide” and included everything I needed to use the SunJack.  Not once did I get confused or need to go online to get additional operating instructions.  To me, a very detail oriented person that likes to do things the right way, this was huge.

The Nifty Camplight LED Bulb

The 4-watt Camplight LED Bulb is equally impressive.  Plugged into the USB port on the battery, it gave off a respectable amount of light.  Of course, you could also plug it into any USB source including a wall outlet or even your laptop.

It has a look at the top plus a long, 7-foot cord which will give you lots of options for placing the Camplight exactly where you want it.

Extra Credit

I thought I would mention that in addition to charging my old cell phone and my brand new, one day old iPhone, the SunJack charged an iPad, iPad Mini, Sony Reader, Nikon camera, and perhaps best of all, a Goal Zero Guide 10 battery charger for AA batteries.


I could not get a decent photo of my electronics charging since, logically, there was too much glare.  The photo above is from the SunJack website where you will also find additional technical information about the SunJack.

This graphic, also from the SunJack website, says it all:


Although it is always best to have full sun available when charging a solar device, most, including the SunJack, will charge up in the shade, but the time it takes will be considerably longer.  Still, with our NW skies, this is good to know.

A nice feature of the SunJack battery is that it has 5 very bright blue LEDs on the front that tell you the charging status of the battery.  Each of the LEDs represents 20% of the battery capacity so when they are all lit, the battery is at 100% capacity.

Something else I want to mention is that the SunJack battery has a built-in LED that can be turned on and used as a flashlight.  A single LED is not expansive enough to light up a room – that is what the Camplight is for – but it is bright enough to help you find your way around a dark room or, if you are like me, find the treasures hidden in the bottom of your pack.

The last thing, for now, is to remind you that it is always a good idea to pick up some extra cables for your devices.  I have extra cables for my phone, iPad, and eBook reader and like to keep them stashed where I can get to them in an emergency.  For example, I keep a set in my bug-out-kit and now, I have put a set in the mesh pouch of the SunJack.  Just be sure that since so many cables that look alike these days, you tag them with a label.

The Final Word

When it comes to my stuff, I prefer to use gear and electronic devices that simply work.  All the better if you don’t need to consult a manual or your teenaged neighbor for help.

The packaging, the usability, and flexibility of the SunJack Solar Power Charger are impressive. At 2 pounds, it is light enough to carry in a backpack and gives new meaning to good things come in small packages.  As a matter of fact, I was so very excited about the SunJack that fifteen minutes into unpacking and setting it up, I said to Shelly “Wow!  This is the greatest thing since sliced bread!”.  Can you believe I really said that?

I love SunJack and you will too.  Be sure to enter the giveaway to win one for free!

Enjoy your next adventure through common sense and thoughtful preparation!

The SunJack® is able to fully charge its internal battery pack in about 5 hours of direct sunlight, or directly power any USB device. When the sun isn’t shining, users can still energize their devices from the powerful SunJack® battery, which holds enough charge to power up to 4 iPhones.

SunJack CampLight USB Bulb:  This 4 Watt USB LED light is bright and ultra-portable at just over 3.5 ounces. It is highly durable – shatter, shock, and vibration resistant.

Never.  They do cost a bit more than those cables you can get for a buck or two from China, but honestly, these work 100% of the time and are about half the cost of similar cables direct from Apple and other manufacturers.

  1. I would send to my Marine son who has been deployed. If these work well in their conditions, I think it may be something to invest in…but I wonder how one would hold up with the dust?

  2. I enjoy backdoor survival and have learned from the articles you post. I would appreciate winning this charger as would many other people. Keep posting the great information. Thanks.
