The Fenix UC02 is a USB rechargeable keychain flashlight. This incredibly small, mini flashlight is powered by a single 10180 rechargeable battery and delivers a maximum of 130 lumens. A reliable twist head activates the two brightness levels. Twist the head off to access the micro-USB charging port (USB cable not included). Completely dust proof and waterproof, this keychain flashlight is perfect for everyday carry.
Disappointing product. Although the battery is fully charged the light will no longer turn on. I've used it less than an hour total and its already dead. Probably why the product was discontinued. Mixed thoughts on Fenix overall. The UC35 I have works well, but this UC02 is dead after short usage.
I love this light for its small size and dual brightness. The USB recharge feature and tiny replaceable battery is an excellent feature for long term use. It's very durable, the ring loop is in a good position and the lense face is recessed just enough to protect it. I've used it a couple of times as an emergency light on my bike for commuting and it's brighter than some other bikes on the road.
However, after about a year on my keychain, it starts to light intermittently -- the circuitboard in the head starts to unscrew itself a bit and the connection gets dodgy. Using surgical metal tweezers as a pin driver, I could screw the board back into position and it works as new!
I like that it starts at the low setting first before taking it to the higher, this way I'm not blinded.
Love this tiny thing. I alway have a phone and a headlight not to far away, but I use this thing all the time.
My only concern is it sometime unscrew itself in my pocket and I loose the little ring that keeps it stiff.
I have one extra remaining, after that it's going to be juggag time.
These are great little lights, super bright, quality build.
