Klarus Mi2 Rechargeable Keychain Flashlight – 40 Lumens

This little flashlight seems like a keeper, so far. It comes in nearly impossible to open packaging with a short micro-USB cord for charging. The flashlight worked immediately and has been fully charged. I know that because when you plug the flashlight in, a red light turns on. When fully charged, the light turns blue. It operates with a simple button push to turn it on. It takes an intentional push to turn it on, so I don't anticipate accidental engagement. If you push the power button again right away, it switches modes to it's highest level of light. If you push the button again, it turns off. Pretty simple. I also discovered that when the light is on its lowest setting, if you push and hold the power button, the light will gradually increase to the highest level, so you have real flexibility in the output level of the light.

The design is similar to the Nitecore Tube, which I have had on my keychain for a couple of years. The tube is a little smaller and has been reliable for me. I'm looking forward to comparing the two over the next couple of weeks. In any case, the Klarus Mi2 looks like a great purchase so far.

After losing my beloved Nitecore TIP SS Stainless Steel Edition 360 Lumen light after only a month I decided I couldn't trust myself with a $45 replacement. So I decided to try this.

It's a perfectly fine little light but at its brightest doesn't quite equal my cell phone (I was wrong - see edit below). To be honest I'd recommend the Finware 5 Pack Mini LED Keychain Flashlight as a better value.

Edit 09/18/2019: Having carried this light for a while I have to revise my estimate to 5 stars. The maximum brightness is at least double my cell phone in the 2-click High mode (user error!). I like the UI now that I'm used to it.

Also, it can be on while charging so you could connect it to a power bank and extend the On time indefinitely. A flexibility not possible with the Finware lights.

I wanted a light, compact, durable flash light to keep with my dog leash now that the days are getting shorter and it makes it easier to pick up poop at night. This flash light is bright and easy to use. I prefer having the button over a twist like most compact keychain flash lights on Amazon use. The dual brightness levels are a plus as well, I can leave it on the lower brightness so me and the dogs can be seen when walking then turn it up when it's time to get out a poop bag. Just received it so can't rate durability yet but will update review as needed.

My work demands a variable output, high intensity small flashlight on a daily basis. I have bought several of those high dollar ones. They all have failed within weeks, if not sooner. They seem more interested in touting how good they are, but don't actually put it to real use. It's all great when you use it once in awhile and it seems bright.
This little gem however, outperforms them everywhere. From price to size to productivity. Just a nice touch...the light never hard turns on or off..it always has a quick fade to it. Your eyes will love that. I have only charged it once since buying it and it still is bright. I use it everyday. Buy this light.

This is my first torch by Klarus but, it won't be my last. Good price. Lightweight and sturdy build. The low setting is perfect for late night trips to the bathroom without stepping on my cat. I would definitely buy this again. I saw more colours available on another site- at a higher price.

I am a night nurse, and I needed a nice little keychain flashlight to throw on my badge. It helps me sneak into patients rooms and not disturb them. I love that it is rechargeable. I keep the charger at work, and I've only had to charge it once. There are two settings, and even the lowest setting is bright. I've already recommended it to my teammates!

I love this key chain flashlight! Even though I gave it 5 stars, I'd give it 4 1/2 stars if possible.

Pros: Small, lightweight, two modes, bright, affordable, micro USB rechargeable, quiet (doesn't rattle with my keys).

Cons: My only con, and the reason I took off half a star, was because the flashlight comes on at times while in my pocket. If it had a power lock, that would bring it back up to 5 stars for me. However, with the USB recharge capability this isn't much of a problem.

I use this flashlight for minor tasks. It stays on my key ring. I haven't got to test whether it's "waterproof" or not, nor would I want to. It's still nice to know if it does get wet while in the rain it'll hold up!

This is one of the better keychain lights I have bought. It's very compact, slim, easy to use. The multiple settings for brightness is very effective. I use the low setting generally as it saves recharging and the brighter setting when I need more light. I would definitely buy this again.

It is a nice size for a keychain, but not very bright.. It will work well for close up 2-3 ft, but beyond that it doesn't help. But for the price it was fine. I bought a surefire, which was quite a bit more expensive, but does a better job.

This is about the same brightness that you get with a phone light but it's compact and very easy to access.
I use it on my night walks with my dogs and it's way less cumbersome than most flashlights.
On high, I get about an hours use.
Quick recharge and I'm out the door again.
Great value.

The light is well made and plenty bright enough for the purpose it serves. The light has come on while in my pocket (on a key ring with 3 or 4 keys) several times. A big improvement IMO would be a long press or double tap to turn it on. The on button is just ok and could be a little more tactile.

This is just what I was looking for, to carry on my after-work walk from office to car in the pitch dark. It's light as a feather and sufficiently bright. Yes, once or twice it's turned itself on while in my pocket, and that would be a nice thing to fix in a redesign. But (so far) it hasn't run the battery down. Thumbs up!

For a long time I had one of the small round ones which turn on with a twist of the head.
The LED got unscrewed and lost somewhere.

This one fits really flat between the other keys. So really a much better solution. And the USB charging allows me to re-charge while driving. So that is good.

It came fully charged. I did a full cycle discharge re-charge. It worked about 1.5 hr on high.

Things to know:
That "continuous, infinite" adjustment of intensity is BS. The speed from lowest to highest is about a 1.5 sec - if you can figure this one out ... you do not need a flashlight - you are a robot already :)

This is NOT a negative. I do not need anything more than Low and High.
Just wanted to mention it as it seems a marketing gimmick.

The charging port is well protected bu a silicone cover.

CAREFUL!

When you try to remove the cover open it from the side of the LED.
This cover fits real snug and you are not sure - should you pull more or should you switch the side you are pulling from.

If you pull from the opposite end you might tear off the stem that holds the cover.

It does come with a charging cable - but for a normal use you are going to need it so rarely - you better remember where you put the cable :)

I've own various little flashlights that vary in brightness and that you can clip in your pant's pocket. However, this little thing just works. It has its own battery that can be charged by any micro USB and it's light enough to hold with your car keys. I bought the Orange version so I can readily find it. It has a two click feature, where the light starts off and a moon level brightness and then gets brighter. I figure it's a great purchase as we head over to October, where the day gets shorter. I think it's 'Clicky Useful'!

I actually bought it to illuminate my tent to get in and get out. It's not bright enough to read by it, but perfect to show you a door and around a tent. I wanted something that I can leave attached and pack the tent with it inside. It's tiny. I wish it was just a tad bigger so it could hold a larger battery and last longer. Lasts about an hour on high, so plenty of time for a weekend of use.

This is one of the best find-the-poop flashlights available for dog walkers. Very lightweight, fits nicely on a keychain, and recharges easily and quickly.

Works well so far. Easy to use. 7 year old figured it out quickly and will have it on a lanyard. Nice and small.

I love it! I actually lost it for a while though since it IS so small and ended up buying two more. Only to later find it. So now I have three! No regrets

I got this for my wife to get to the bathroom at night. The button is too hard for her fingers and she can't get the quick punch to start it on dim. It ramps far too quickly to bright. After several months of use, she still struggles to start it dim. I still give it four stars, because it is of decent quality and good brightness for a keychain light. Most people will operate it fine.

All the other rechargeable keychain lights would make my keychain too heavy. I wanted something small and lightweight.

I was worried if the light wouldn't be powerful enough since it's so small, but it's actually great for its size.
Very satisfied.

On the low light (0.5 lumen), it will .last 24 hours and on the bright *40 lumen) it last 1 hour and ten min.! I highly recommend this flashlight!!! Itt is great for looking for your door key at night ect! I bought all 3 colors !!

Have only had the light for a few weeks, so long term we will have to see, but so far it has held a charge and has a very bright light.

I have been using this light at work as a nurse because it has two brightness settings appropriate for looking in eyes and mouths. I didn't realize it was rechargeable and I came here looking for a replacement battery. I am so relieved I can just recharge it on the same line as my phone.

Got one for me and my mom and we both love them. puts out more light than expected. love that they can be recharge with buying batteries all The time.

I got this for my secret Santa, he asked for a light. I also have one. It's so light is doesn't pull on my badge.
I work nights and it's so perfect to just look in on my patient or check an IV. Very much recommend this. Plus it's rechargeable is the bees knees!

5/21 - I like to be able to recharge the internal battery via USB rather than having to struggle to open and REPLACE expensive coin-size batteries.
12/23 Update: It lasted 2-1/2 YEARS before the switch got too hard to activate. The light is still as bright as ever.

Great design. The bulb extends out so it’s sort like a lamp. Don’t have to point it at a key hole to see it. Just get it close to what you want to see and you can see it without pointing it. Good battery life and brightness.

I’m a nurse working the night shift! This is perfect for “tasks” at night without waking the patient! I put it on my badge reel and it works great! Leaves both hands free for setting up IV pumps or taking vital signs! Highly recommend!
