It is always a pleasure to work with the Sunjack folks. I was excited when they asked me if I would like to review their Weatherproof LightStick. This is a LED flashlight in the form of a lightstick and can also be used as a battery as well. It is also waterproof and shock proof and is fairly compact size compared to other lightsticks I have seen around. Let me tell you about some of the key features of this product:
LightThe first feature I should mention is the light. This light stick has four modes. There are three brightness levels up to 350 lumens and a strobe setting. Sunjack claims that the light will last for over 40 hours on the lowest setting on a single charge. I left it on full power for quite some time and it took the battery level indicator a long time to even move. I did manage to get it to shut off after leaving it on its brightest setting overnight. It did drain the battery to one indicator light, but did not drain it completely. It seemed to have shut off when the battery got low.
WeatherproofThis product is IP68 rated. This means is that it is dust proof as well as immersion proof. This rating means that you can basically drop it into 1 meter (3 feet) of water or up to 3 meters depending on the manufacturer. Sunjack's website indicated it was good for six feet (2 meters). While running my own tests, I found it to not only be waterproof, but I also found that it floats which can be nice should you drop it in a lake or river. In other words, unless you plan on swimming under water with the light stick, you probably won't need to worry about it going even a few inches below the surface.
ChargingHaving a backup battery is a very important thing to have. I don't know how many times I used up the battery in my smartphone and was stuck because I was off somewhere where it was not possible to charge. The 5200 mAh rechargable internal battery offers some serious battery life. This is around twice the battery life of a high end smartphone. With the 2 amp USB output, you have plenty of charging power for plugging your cables into the standard USB port. Recharging the lightstick battery is simple with a standard micro USB input. Both the USB output and the micro USB input are protected under a waterproof cap to keep the ports protected while outside or in storage. Sunjack also offers solar chargers that do an excellent job of keeping the lightstick charged so you can keep your it charged this way instead of plugging it into your wall or car chargers if you prefer. Also, with the lightstick battery you can easily charge larger devices or even batteries that allow for USB charging.
- LED Indicators The LED indicators make it very easy to determine how much battery life you have left. I found the LED indicators to be bright enough to be used for a night light, but I couldn't figure out a way to keep them on for a length of time without it being charged or charging something. Anyways, it probably wouldn't make much sense anyway since they would go off one by one as your battery drains.
- Shock Proof If you are hard on your equipment, this lightstick can take a beating.
- Lanyards I like the two lanyards on the lightstick. This means you can easily hang it vertically or horizontally.
Overall, I think this is another excellent product by Sunjack. I plan on keeping this in my truck with my Sunjack solar charger so I should theoretically never have an excuse to be without power for my mobile devices. be sure to check them out.
