Review: Good EDC light. - Easy operation, solid build, well designed, and inexpensive. The brightness level is impressive especially for a flashlight this small. I also like the different light modes, they are useful and practical. The advertised run time seemed to be accurate (at lowest level, about 50 + hours). Charging is fast and the battery is removable, this means you can have a spare battery that will allow you to run this light longer. Another good thing is that you don’t need to buy a proprietorial Wuben battery, you can use any 18350 batteries. Finally, it has the right weight and size, perfect for EDC. This is definitely one of the best Chinese made flashlight in this price range ($20+). Highly recommended.
Review: Very good mini light - I am very pleased with these lights. They are compact, highly luminous, durable, and can be easily clipped or magnetically attached to various surfaces. While numerous inexpensive options exist, these lights stand out due to their exceptional brightness, quick charging capabilities, and ability to withstand considerable impact. The robust metal construction, including the clip, provides a sense of quality. Although not tested underwater, they have performed admirably during heavy rain. Their versatility is remarkable, offering adjustable brightness from a subtle glow to intense illumination. While the turbo mode generates significant heat and has limited runtime, it is readily accessible with a few quick clicks. The battery life is sufficient for our use as on-off lights, and I have found them consistently reliable. Overall, these lights offer excellent value and robust construction. I have subjected them to drops, drenching, and creek rinses, and they continue to function perfectly.

## Questions & Answers

**Q: Why does the flashlight have poor contact after replacing the battery with the extension tube?**
A: Because the battery we use in WUBEN is a battery with a 0.05mm charging protection board (size: 18x70mm), which can increase the safety and service life of the battery;

**Q: What is the function of the extension tube?**
A: It allows us to choose whether to choose different batteries according to our different needs.

### ⭐⭐⭐⭐⭐ Great flashlight. Had to buy 18650 3.7v batteries to fit in the extension.
*by C***O on May 31, 2026*

I love this flashlight. It's a little pricey, that's the only downside. I got the whole bundle in green for 40 dollars. The sensor doesnt let you wave your hand, but you just tap the sensor and it turns on. The size of the flashlight is great too, but i also got the extension for the bigger battery. Just bought the batteries for 20 bucks. So im into the flashlight for at least 60 bucks. But I say its worth every penny so far. The light brightness is great too. The dim is really dim, and the bright is really bright. They also have a turbo brightness that is slightly too bright. Thats what I was looking for. When the light is in the headlamp harness you can tilt it up or down. Tilted down puts it at the perfect angle for a headlamp. Actually one more downside is the part that sits on your forehead is not the most comfortable thing, but its still wearable. I would be down to have some padding on it. Also looks like there is a spot to put another strap on the handbags harness. Wondering what that thing is for. I will be back after I test the 18650 3.7v batteries that i got for the extension adapter. Edit: I came back to say that finding the 3.7v 18650 button top lithium ion battery on amazon has been an ordeal. Ive now spent over 50 bucks trying to get a battery to use the adapter on my flashlight. I still dont have the battery. I have a nice case for batteries and a 25 dollar 2 port charger that I got tricked into buying.. if you buy this flashlight and still need the longer battery, go to home depot for the battery. They have chargers too. Amazon has 8 dollar chargers but if they are as big of a scam as the batteries I wouldn't trust it. Any battery over 3500mah is a scam, especially over 5000mah.. be careful out there, China has gotten real good at making fake batteries that work long enough to fall outside the return window.
