I1R 2 Pro Eos 180 Lumens EDC Rechargeable Keychain Flashlight, Powered by Built-in Rechargeable Battery with Type-C USB Cable, Slim Mini Handheld Light for Everyday Carry (Black)

I first learned about these lights from Chris Boden’s YouTube channel, and they have proven to be excellent portable flashlights. The high and low modes are genuinely useful, with enough brightness to clearly see what you’re doing. They are extremely compact, about the size of an AA battery, and fit perfectly on a keychain or clipped to a bag. The construction feels very durable and well-made without adding unnecessary weight. USB-C recharging is convenient and fast. Overall, this has been a great purchase.

Keychain flashlights are really handy tools to always have with you. However, my last two models have had the problem of turning themselves on in my pocket and then when I need to use them, the batter is dead or almost dead. My last one was a high quality Fenix 03R (not V 2.0). It has 4 brightness levels where the lowest has a very long runtime and the the highest was very bright. It also had a separate red light with one brightness level and a flashing function. The button was perfectly flush with the body and it charged via USB-C. If it wasn't always dead it would've been the ideal keychain flashlight. It was very good and very useful when it was working. However, almost every time I took it out to use it wouldn't turn on or would flash twice (indicating low battery) and then turn off. It had a lockout function, but I never go into the habit of using the lock-out function and then unlocking it every time I needed to use it. It would've been annoying too. This light is worse in terms in features. Only 2 settings. The low setting is very low, but lasts long at least. The highest setting isn't nearly as high as the Fenix light, but good enough. I'm glad it charges via USB-C since I'm trying to switch all of my devices to use that (note that the front of the light partially blocks the USB port so you have to get it in, watch for the charging light to come on and then don't touch it or it will come out just a tiny bit and not charge, the included charging cable is slimmer than most so it doesn't cause as much of a problem, but if your cables are fat at the end you won't be able to get it in far enough to initiate charging). But the thing that is most important is that it is ready to go when I need it. The best flashlight in the world is still useless if it is always discharged. To turn this light on you need to push the head in and twist it a few turns for the weak light, then twist it a turn and a half or 2 to get it in to high output mode. This isn't something that can accidentally happen in my pocket, so I am happy. If there was a light that activates like this, but comes with the robust feature set of the Fenix I would be in heaven, but this is what I want and is good enough for me.

TLDR; Exceptional brightness and ultimate convenience in a minuscule package. The 180-lumen output and USB-C charging make it the best ultra-compact light for a keyring or pocket. I purchased the Olight I1R 2 Pro Eos because I was tired of fumbling for my keys or looking for things under the couch with my phone's weak, flood-style light. I wanted a true, dedicated light source that was so small and light I would forget it was on my keychain until I needed it. The move to USB-C charging on this "Pro" version was the final push, as it matches all my other modern EDC gear. The performance of the I1R 2 Pro is astonishing given its size. Pumping out 180 lumens on High mode, this tiny torch throws a surprisingly focused beam (up to 48 meters) that absolutely obliterates a smartphone's flash for finding a dropped item or navigating a dark pathway. The default Low mode of 5 lumens, which activates first with a gentle twist of the head, is perfectly calibrated for close-up tasks like finding a keyhole or reading a map in the dark without destroying your night vision. Switching between the two modes is simple: a slight twist for Low, and a full twist for High. The head is "captive," meaning it unscrews to reveal the USB-C port for charging but does not detach, eliminating the risk of losing the head—a massive improvement over previous designs. Charging is fast—about 100 minutes—and the upgrade to the modern USB-C standard is a massive win for compatibility and convenience. The integrated 130mAh battery provides up to 12 hours of use on Low, which is more than enough for intermittent keychain use. Its durability is also noteworthy, with an IPX8 waterproof rating and robust aluminum construction that shrugs off being constantly jingled with keys. Pros and Cons Pros 180-lumen maximum output is exceptionally bright for a keychain light. Modern and convenient USB-C charging port. Extremely compact and lightweight (only 22g / 0.78oz). Simple and intuitive twist operation with two useful modes. IPX8 waterproof rating provides high durability. Cons High mode runtime is brief (23 minutes before stepping down) due to the tiny battery. The "Cool White" LED tint could have better color rendition (CRI). Built-in battery is not user-replaceable. Verdict The Olight I1R 2 Pro Eos is, without question, the best keychain flashlight available at its price point. It successfully bridges the gap between ultra-portability and true utility. It is best for the everyday carrier who wants a genuine, high-power light source always available, not just a novelty. If your primary need is quick, powerful illumination for brief moments throughout the day, the I1R 2 Pro's high output and easy USB-C recharge make it an essential and highly recommended addition to any EDC setup.

I always like having a keychain EDC light on me vs a penlight style. I usually use the light on my phone, but I just like to have a small backup. I have been using the Streamlight Nanolight for several years. I really like the light and its size, but the output is a little anemic in some situations. The i1R2 is just a little bit bigger than the Nano but the light output is much more powerful. I like that the light has a 2 stage brightness levels without having to program a switch. Tighten the lens slightly and the low power light comes on. Tighten it a little further and the light goes to the high power mode. Very intuitive and it works the way you would expect it to. The twist style feature is the same as the Nano and I was concerned about both turning on in my pocket, but that has never been an issue. The construction of the OLight is top notch as all of their products have been. It's case is aluminum, nicely knurled, and black anodized. I really like the usb-c charging port. I always have a charger around and it's nice not having to worry about batteries. Unscrewing the lens end reveals the charging port. There is a light spring that opens it fully once it is unthreaded a few turns. The lens does not unscrew completely, but remains captive which is nice. There is also the requisite "O"-ring for twist resistance and keeps the electronics free of moisture. The threads grab easily when closing up the charging port and do not feel as though they could be stripped out. There is a small key ring on the tailpiece to attach to my keychain or it could be used with a lanyard. I just started using the light so I can not say what the durability and longevity are, but Olight products have a reputation for quality so I am not too concerned. You can never have too many flashlight! This one is very nice, give it a try.

Excellent baby light. I'm a welder and I use it every day. I also have to charge it about every other day. Small light. good illumination for inspecting welds. durability - I have used this unit for about 6 months now. It is very nice if you want a very small light or a backup light. Recently the lower light function became more or less disabled. The advantage and weakness of this light is the threaded light intensity function. turning the light on and off rarely engages the low light option now, but will always turn on the full intensity when fully unthreaded still. function - threading the unit closed will turn the light off and protect the charging port and internals from debri/pocket lint. If you work in an environment like me with some grit and grime almost always around, the threads will wear down a bit over time, but still function surprisingly well. They come well lubricated out of the box and have not need much attention. usbc charging. really should be standard, but its a great "feature". fully charging may take about an hour, a quick charge to get it running 6 hours is very fast.

I’m a flashlight dude and have several decent lights (mostly Streamlight and Surefire) but I never had one this small, really. I love the low setting and high is very bright. The biggest selling point for me was the usb c charging as I’m on that never ending mission to live a “one charger/one cable” lifestyle. I bought about 10 of these for Christmas gifts and everyone claims they love them. (Unanimous love for the usb c charging.)

The Olight i1R 2 Pro Eos is extremely lightweight, extremely bright flashlight on my keychain, which allows me flexibility when out and about. Especially in winter, it gets dark very early where we live. This flashlight allows me to see amazing detail of anything that might give me problems--how many of you have ever come face to face with a skunk on your sidewalk at night? It is very handy to use to open the lock to the door on those dark nights. I love that I don't have to worry about buying batteries to replace spent ones. This recharges very quickly and lasts a long time. The array of colors allows me to color code for family members and to pick a color I can find in my purse! That saves a LOT of digging! The flashlight is well designed--easy to turn on to a dim light, then a little further twist brings the fully bright 180 lumens to bear on whatever you want to light up. The charging port is right in the short handle with a twistable cover to keep it clean when not needed. I think everyone should have an OLIGHT keychain flashlight. Get them when Prime Days deals are on. These are very worth every penny! Love this Little Light of Mine!

Great little flashlight! Perfect 2 stage brightness for the simple activities that this flashlight was designed for. I have several Olight flashlights all are great quality and durability. Their products can cost a little more, but they are very worth the price. Olight will last and perform without issues time after time. Very pleased with this latest purchase, I'll be purchasing more of this style to keep in my IFAK and my vehicle center console.
