Features and Performance
The SunJack LightStick is made of plastic and it is significantly bigger than disposable light sticks we’ve been already familiar with. It has a solid build and I feel very sturdy holding it in my hand. I actually dropped it to a hard floor once but it still seems perfectly alright. In my test, I also used it in the rain for a couple of minutes and as you can see, it still survives. So, the waterproof feature seems to be legit as well.
The product has a simple design and it is ready to use out of the box. I don’t know how long my product has been kept in their warehouse but when it is delivered to my office, the battery is still full and I didn’t need to charge it at all. I turned the light stick on at the highest brightness and it easily could last for more than 4 hours. There is a battery indicator on the body of the light stick, so you can easily check how long it could last. The manufacturer states that the battery could last up to 46 hours at the lowest brightness setting.
The button on one end of the stick is used to change the lamp brightness from low to high. You also have a flashing mode that I find very useful in case of emergency. The light can flash very bright and more importantly, the battery could last up to 49 hours. On the other end of the stick, you can see a USB port and a mini-USB port after twisting off the waterproof cap. The USB port is used to charge your mobile device while the mini-USB is used to charge the light stick itself. The built-in 5200mAh battery is enough to charge your high-end smartphone twice, it also supports fast charging 2A output.
The light emitted from the lamp is purely white and it is amazingly bright at 350 lumens. You can check out some pictures below to see how bright it is
