Gear Review: SunJack Waterproof Lightstick

If there is one thing that we all share in common, it is our interest in having adequate light to brighten our way when the grid is down. Perhaps that is why some of us, no names mentioned, has over two dozen flashlights of all sizes and types. And that is in addition to chemical light sticks.

With all of these portable light sources, what if you had a powerful source of light that was not only bright enough to light up a room, but was waterproof and rechargeable using any USB source? And better yet, what if it could also be used to charge up your phone, eBook reader, or other USB device?

Review of the Sunjack Waterproof Lightstick - Backdoor Survival

Today I would like to introduce you to the SunJack Waterproof Lightstick which is, indeed, one very handy piece of equipment to have around. Not only is bright but from what I can tell, it is pretty much indestructible. And the best part? The nice folks at SunJack, who you might recall from the review I did on the SunJack Portable Solar Charger, have set aside one SunJack Lightstick for a lucky Backdoor Survival reader.

SunJack Waterproof Lightstick – Just the Facts

In my usual style, I want to show you the Lightstick in action, but first, let me share a few of the basic facts.

Shaped like a long tube, the SunJack Waterproof Lightstick is about 10 inches long. The end cap includes a green power button that toggles between low, medium, high, and strobe. Depending on the setting, one charge will deliver up to 46 hours of constant light.

The stated charging time is 4 to 5 hours. It can be charged up using any USB source including a wall jack or a computer USB port. That said, I hooked the SunJack Lightstick to my SunJack Solar Charger and found that it took a bit longer given that the day was cloudy and overcast.

For the technically inclined, the output is 5V 2Amp and the maximum output wattage is 3.5W.

Practical Uses for the SunJack Lightstick

Given its slim profile, the SunJack Waterproof Lightstick is ideal for bug out bags, get home kits, and vehicle emergency kits. I find that it fits neatly in my pack, right alongside a LifeStraw which is are similar in size.

At the full power setting, and even at low and medium power, this is a very bright light. Impressive, actually, given its compact form factor.

If kept in a vehicle, it can be used as a trouble light when checking under the hood or as a spot of bright light when changing a tire. It can also be used as a flashing signal requesting help if stranded by the roadway. It would definitely light up a campsite at night with the added advantage that it can be charged with a portable solar panel during the day while not in use.

Another practical use is to use it as a beacon when traveling with a group. The leader can raise it above his or head in strobe mode to signal to the pack of followers. Being totally waterproof, using the Lightstick out in the bush or on the trails would be no problem at all.

Speaking of waterproof, I took the SunJack Lightstick down to the shoreline and set it afloat in salt water. I left the light on. The only problem I had is that it started to float away! My fault totally but the good news is that it floats, making it difficult to lose if suddenly tossed in the water during a flood or storm.

When it comes to charging power, I was able to charge my iPad, my Kindle, and my iPhone from a single charge on the SunJack Lightstick. Each device was at about 60% at the time but given that the LED indicator lights still showed a charge on the Lightstick itself, I am confident that it would have charged them from a full-out run down state.

  1. Other than flashlights, I only have candles, a few oil lanterns, and a container of Crisco made into a candle.

  2. What is awesome about this light is the 40 hours of light. Most of the lights i have only last 20-25 hours at the most.

  3. I have flashlights, two LED lanterns, plenty of batteries, one wind up flashlight, and candles. It will get me through the normal lights out events we have around here. Need to replace my outdoor dedcorative solar lights – the newer ones are much more reliable than my fairly ancient models. They offer a source of gentle lignt when fully charged. Bigger stuff – going to go to bed with the sun I guess. The light stick would be a nice addition to my supplies.

  4. Besides flashlights we have candles, glow sticks, headlamps (love them) and have thought about getting a solar lantern as well. The solar lightstick would be a great to have for emergency situations as well.

  5. Great site. We have candles and a coleman lantern for lighting in addition to flashlights. I like the idea of chemical light sticks in emergencies.

  6. I have Candles and Camp lanterns w/fuel and oil lamps with fuel I would really like to win this. I am so glad I found this site!
    Thank you Gaye

  7. Oil lamps (lots of extra wicks and oil), candles (in the freezer – they burn longer when cold), rechargable lanterns, solar outdoor lights, and flashlights (stash of batteries and solar recharger. But what a great addition this light would be! Thanks for all you do!!

  8. Besides flashlights, we have Candles and oil lamps if needed among other items we can use if needed after these are no longer.

  9. We have some candles and a flashlight, so probably not as well prepared as we should be at this point. Small steps…

  10. btw, i can’t get the FB entry on the rafflecopter to work. i went to your FB page & liked the post, but the rafflecopter just sits there when i click that one. :/

    • You should see a blue “I visited” box in the lower right hand corner of the FB Rafflcopter option. Click on that and you are done. I just tried it and it worked so perhaps there was a temporary glitch at your end?

  11. We all need one of these. Not light means stumbling about in pitch black darkness
    vulnerable to danger if only falling over a toy on the floor.

  12. SunJack seems to make Good, High Quality items. I have several of their 4W USB Camplight, and LOVE them. I will get one of these Lightsticks in the near future.

  13. Besides flashlights, we have solar lights, LED lanterns, regular and 100 hour candles, oil lamps, oil and propane lanterns, and headlamps. We’d love to add this light stick to our collection.

  14. We bought a bunch of those solar yard lights, plus we have those emergency essentials 100 hour candles, and regular candles, and 3 oil lamps.

  15. Love the recharge feature on the Lightstick. I can definitely see a Lightstick going into my son’s 24hr pack for his activities. We have some of the mini LED flashlights that take AAA, we have the big “beat a baddie” D-cell monster, and a bunch of varieties in between. There’s a battery operated Coleman that was used with Cub Scout camping in the boys’ tent. In addition to those, we have candles, glow sticks, and a decorative (but fully functional) flower bee hurricane oil lamp bought at Christmas Made in the South several years ago.

  16. I have a collection of antique oil lamps that I get to enjoy looking at each day that also have a practical use.

  17. I have a Coleman lantern, some chem lights (light sticks), and candles. Most of my light however is from flashlights, I probably have as many as you do 🙂

  18. We have candles, more candles and more candles. I have a couple of oil lamps, solar lights, and 10 hour glow sticks in everyone’s BOB’s. Have 100 hour emergency candles. But my favorite things are my jars of bacon grease and cans of tuna in oil that go with my supply of candle wicks! Instant candles 🙂

  19. Candles, LED lantern and currently one oil lamp with a few containers of lamp oil. I plan on getting a few more. The one I have was only $10 at Wal-mart. Most antique stores carry a slew of them as well. I need to stock up on more fuel as well. I also want to get some of those UVPaqlites. Have you tried those? Available on Amazon.

  20. Aside from flashlights, we have many candles, of different sizes. We also have a few lanterns, being careful when using indoors. I would like to look into getting some oil lamps, that are refillable.

  21. We have a lot of flashlights, rechargeable batteries and a solar recharger, tons of candles and tea lights, my grandmother’s antique oil lamps and plenty of bottles of lamp oil, 2 Little Sun Lights, Waka Waka lights and head lamps.

  22. I have several flashlights w/ extra batteries, my voyager radio which has a light, several oil lamps, need to get some 100 hour candles,2 propane canister lanterns, and 1 solar light. Need to obtain some scented oil for the oil lamps.
    Would really like to have one of these.
    Thanks for all you do.

  23. Besides flashlights we have candles,100 hour candles, tea lights, oil lamps, Coleman lanterns and crank style radios with lights.

  24. I have a couple of oil lamps and some candles, plus a solar powered lantern. This would be a great addition. Thanks for reviewing it.

  25. With my battery and shakable flashlights, I have candles and a few headlamps. I could use alternatives for sure.

  26. I have an assortment of oil lamps. Dietz lanterns in two sizes along with Mag lights and plug in emergency lighting in two of our most used rooms. We also have a shake light and a dozen glow sticks for our bug out bags. Our dogs even have light up dog bone shaped lights for their collars so you can find them in the dark.

  27. Besides flashlights, we have a couple of hand crank lights, oil lamp, battery powered lanterns, and candles. At the end of summer, our local discount store drops the price on solar powered yard lights to $1. I picked up a few of these last year. Tried them out one night and they lasted about 12 hours on a full charge. Will use them first in an extended power outage to save on batteries.

  28. We have glow Sticks and candles. The glow Sticks are great for the kids and for attaching to the top of bags so they are easily found in the dark.

  29. In addition to flashlights I have oil lamps, candles, crank lights (not flashlights), and the solar yard lights that can be used if needed. Also, for a low light I can use my tablet (android/kindel).

  30. I also have a headlamp, candles and crayons to burn. This light stick would be a perfect addition as it doesn’t have a flame to burn the forest down and is not as dangerous as a hot candle.

  31. Candles, light sticks, I even went and bought that battery jumper/air pump/light from harbor freight you talked about a ways back.

  32. The “Sun Jack” lighting tool is definitely cool… a very bright idea!

    Other than flashlights, cases of those $5 candles-in-a-jar. The candles are safe while burning, easy to snuff-out with the lid when not using, and the jar can be used for other things when completely burned-out.

    While the “Sun Jack” is would seem much better for the average citizen…
    my candles would be much better if placed on all the seats in the halls of Congress!

  33. I have lots of flashlights, candles, and hope to get some solar rechargables like this! Very Nice. Thank you!

  34. I have candles and many, many flashlights but want to add some solar lights like this to my preps! Thanks for introducing this and for the chance to win.

  35. Oil lamps, Candles, camping lanterns and some rechargeable LED lights. The LED lights are about 18″ long, they almost look like mini fluorescent lamps. They really light things up.

  36. I buy inexpensive solar lights. I figure I can put them outside during the day to charge up, then bring them inside to light up the house.

  37. I have lots of candles, I am kind of a candle addict. 🙂 My husband collects antique and unique oil lamps & lanterns, although we buy the odorless oil for them, much easier on the body (otherwise I get a BAD headache), we also have little oil candles (much like the 100 hour candle, but votive sized), and I enjoy solar outdoor lights, so those can come in in case of emergency. And we have a few glow sticks scattered around here & there, they don’t give off a whole lot of light, but in the dark they are great to light up just enough to keep you from bumping into each other or chairs, tables, etc. Someday we’ll get solar hooked up, but in the meantime we do have several inverters and extra long-life (boat/atv) batteries stocked & charged and a few 12v lights. They’re the kind you would buy for a camper and they work GREAT!

  38. I have mostly flashlights that have to have batteries provided. This would be a great, and very useful, addition to anyone’s preps!

  39. Besides flashlights I have a modest candle and match supply plus a couple dozen lightsticks. In other words, not near enough.

  40. This looks like a very good product. It is good to try to multiple types of lighting. We do not have any solar lighting products. Something like this would be a good addition.

  41. Other than flashlights, we just have candles and camping lanterns. We do not have anything solar as of yet.

  42. Solar lantern, candles,both traditional and liquid paraffin, as well as some vintage oil lamps and supplies.Am stashing odds and ends for several types of improvised lighting.

  43. Oil lamps, candles, solar lights, lanterns (fuel and battery powered), head lamps, hand crank lights.

  44. I read this as WATERPROOF LIPSTICK ha ha on me, and thought good idea. Well you never know when a little lipstick could help. But lightstick thats useful to. I have lots of candles, kerosene lights, camping lights and flashlight.
