"Awesome light, small and classy! Fits great in 5th pocket/coin pocket. The two modes are very useful."


















The MecArmy X3S micro USB rechargeable keychain light follows the latest trend of big power from small lights. This keychain light measures under two inches long, and yet is powerful enough to deliver a 130-lumen output. Lights this small typical delivery a maximum lumen output that is less than 100, so what sets the X3S apart from its competitors? For starters, this keychain light runs on one 10180 Li-ion battery, which provides enough power to delivery such a bright output from such as small light. Additionally, this portable flashlight is available in either copper or brass materials. Though heavier than titanium and aluminum, due to the small size of the X3S, the extra weight of the material won't be uncomfortable or disruptive to your everyday routines. Not only is the X3S copper and brass flashlights unique collector's items, but they are also usable on a daily basis.

Simply twist open the head to reveal the hidden port. There is no need to remove the battery or the head from the key light, therefore eliminating the possibility of lost parts. All you need is the included Micro USB cable and a power source to re-power the 10180 battery in just 1 hour. A built-in charging indicator will glow red while charging and green when complete.

"Awesome light, small and classy! Fits great in 5th pocket/coin pocket. The two modes are very useful."
"So I bought this to replace a Jetbeam flashlight of the same size that flickers a bit when on. The X3S is HORRIBLE. When it functions, the color, beam pattern and brightness are fine. That’s is the end of the good qualities. The light will not charge with about half the micro USB cables that I have, including the one that it came with. The laquer on the body is peeling off and the patina on the copper body is an ugly green/grey instead of a nice copper brown like other raw copper that I have. Today, the head of the light fell off completely when hanging on my necklace, despite the fact that the head is so hard to turn that it requires two hands to operate. After reassembling the flashlight, the battery was drained, which makes zero sense, as the head tightens to turn on and loosens to turn off. The X3S is complete garbage. I would absolutely recommend NOT buying one of these lights."
"If you drive you always have your keys with you, right? Hang this little light on our key ring and you will never know it is there until you need it. That is when the brightness will surprise you. I just ordered another one--for my wife. She keeps wearing out the little free ones that Battery Junction sends out with their orders. It holds a charge for a long time. I have charged my only twice since I purchased it and I am constantly using it. My second favorite light!"
"I love the weight the feel and the lighting great for a keychain !!"
