Anker Rechargeable Bolder LC90 LED Flashlight, Pocket-Sized Torch with Super Bright 900 Lumens CREE LED, IPX5 Water-Resistant, Zoomable, 5 Light Modes

Anker makes very high quality products and is one of the most reputable Amazon brand type products I’ve ever used! Boulder Flashlight Review: Thank U Anker for providing HONEST LUMEN RATINGS unlike sooo many flashlight brands on Amazon claiming 1000-100000 lumens when they only output 10-30% of that. These Anker Boulder lumen ratings seem extremely Acura TE if anything I would say they are brighter than their rating. I own both Boulder lights this 900lumen zoom able and the 400lumen which is my favorite it is much smaller and still super bright and rechargeable. They are both tough lights I use the 400lumen at work almost daily for Tig welding on tool steel. Put this flashlight in a magnetic flashlight holder stick it to the die and now I can weld for 1.5 hours easy on high light with the 400lumen. The 900lumen can do that for about 3 hours. It os very bright light and make welding much easier in darker places. I use it hunting or taking dog out. Then just put it on the charger and it’s good again. Easily one of the better flashlights I’ve ever owned and for the price it is the best. My stream light pro tac AA is still my favorite but it’s also $40 and half as bright as the 400 lumens. It is still the most rugged tough light I’ve ever owned . I’m on my second one I wear it on me at work every day. I like having a light that I can just put batteries in when needed also so if needed I can. My work provides AA batteries . I have dropped it roughly 40 times. Falling out of mag holders or falling or rolling off stuff. It still work it is amazing. Well these Anker boulders are not that tough but they are still very tough. They can also handle being dropped. They seem to have a limit though I had one fail where u really have to shake it or tap it to get it to light but it took a beating. The quality is great the price is great. Can’t go wrong. A stream light like this would cost 4-5times the price. I can’t afford to buy a bunch of stream lights especially when these perform soo good do a great price.

I did buy this on sale for about $23 a couple years ago, and the price is now $34, but I still think it’s a great deal considering the quality of this light. It’s extremely bright. Anker products are well known for their high quality, and this is no exception. The light holds a charge forever! I keep it in my vehicle and it’s always ready to go. It has an adjustable beam that you change from wide to focused by pulling in or pushing out the lens assembly, and the soft wide beam gives a good wide beam of light while the narrow beam gives a bright, focused beam that illuminates a good distance away. Standard beam, flicker and SOS I think, I never use the others, but I do know that if one were coming up on a trespasser at night and used the flicker/strobe feature it would be very disarming to anyone it was shining on because of the brightness and “chaos” of the strobe, and it would work really well if stopped on a dark roadside for safety against oncoming traffic! I have many Anker products and love them all, and this one is a favorite! I didn’t rate water resistance because I’ve never had it wet, but I would imagine it’s as good as any and am certain it would be fine in heavy rain due to the build quality and tightness of moving parts/seals. The ONLY thing I wish Anker would do that they didn’t with this light is offer a red and/or blue lens cap accessory, there are MANY uses for such caps including enhanced roadside safety and emergency uses. PLEASE Anker, produce colored lens caps for this and other lights like this one!

I just got my LC90 today and I already love it. It's stunningly bright, literally. Turning the strobe function on in an already relatively bright, indirectly sun-lit room is an unpleasant experience. I can't imagine what it would be like to have that flashing straight in your eyes so I can see now how it could be used for self defence. The beam lights up the top of a tree a solid 100 yards from my apartment. It's incredible that this much light can come from a single led. The flashlight has a nice, solid feel to it with good fit and finish throughout. It's perfectly sized: not bulky but just a little bigger than a pocket flashlight. It feels good in the hand. The zoom feature is very smooth with just the right amount of resistance. The beam pattern is clean without hot spots (unlike my Maglites). The micro usb charging port is very clever and gives you a lot of options for being able to charge the unit wherever you are without having to carry around a bulky charger. Plus rechargeability means you never have to struggle with thoughts of "oh my flashlight's batteries are wearing down just a little bit and my flashlight is getting dimmer. I *could* replace the batteries (if I have more on hand, at $1-2$ a pop), though the flashlight's still working. It's just unsatisfyingly dim now." I don't know about you but I right now have 4 other flashlights sitting in a drawer and they all could stand to have their batteries replaced. The batteries alone would cost half the cost of this flashlight so I went ahead and upgraded instead! Now my flashlight will always be ready at full power. One or two people here complained about the flashlight having too many functions, but it's great that the flashlight remembers the last mode you had it in so if you mostly use it in its medium brightness mode, it will be set that way whenever you pick it up. I have a Mini Maglite, a 2 C-cell Maglite, and an old school but still excellent Streamlight 3 C-cell LED flashlight (circa 2005 and still running) and they all pale in comparison to this LC90. Buy it, you won't regret it!

Nice light. I bought two, a few years apart. The first I like better--you can actually replace the battery yourself if desired. They glued the battery in on the new model which I do not appreciate. Though you can easily break the glue bond with some cushioned pliers and replace the battery if necessary (videos available), tho this will likely void your warranty (and Anker is historically very good with warranties). Light travel/intensity is great for my general purposes chasing cows out of my back yard and one for the truck, and tests show the stated lumens are accurate, unlike 95% of flashlights sold online. High beam is nicely bright on a full charge but dims somewhat after 5 min on high, or so. Still bright, just not maximal. The adjustable beam is very nice, though I wouldn't complain if the tightest beam was even narrower. I like this flashlight very much. I bought two. However, I have two primary complaints: 1) You must cycle through the 3 steady-beam intensity levels, the strobing level, and the (silly?) "SOS" level to return to the highest beam. This can be obnoxious. Personally, I need high beam always. I would probably not even mention it if it had 3 steady beam levels you had to cycle through. But for me, the strobe, although bright and obnoxious, isn't going to stop any determined attacker, and the "SOS" signal just seems silly and unlikely to ever see any practical use, even if you get lost in the woods or break down on a dark highway. Ok, but I knew this when I bought the second unit, so obviously I can live with it. 2) Battery compartment redesign so you 'cannot' access and change the battery. This is a major flaw in my opinion, and the reason I probably won't buy a third light for myself or for gifts unless this is reverted. Both older and new styles unscrew at the rear to expose a USB plug-in port for recharging (takes a couple hours to refill). Ok, unusual but I can live with it. The older model also would unscrew to reveal the battery that could be changed out immediately with a spare to get you right back into use. The new model has the battery compartment glued shut so nope, no spares for you--unexpectedly out of juice in the dark woods? Tough--find someplace to charge it for awhile. Naaah, no thanks. That also means that your flashlight is a disposable flashlight because when the battery dies, and it will eventually die (after they start degrading noticeably in battery life), you 'cannot' replace it. That makes it a very expensive flashlight. Anker's got a great 18-month warranty on most of their products that is admirable. But this is planned obsolescence that is not appreciated. On the old model if your battery failed after 18 months no big deal, just pop in a new one. On Anker's new model if it fails after 18 months, well, guess you gotta buy a new flashlight. Ridiculous and transparent. And not appreciated. It's also nice to be able to carry spare flashlight batteries camping and such and not having to wait hours for a recharge (if even possible while camping--certainly not convenient). Nice light. Good company and warranty. Crummy redesign that lowers its value.

I purchased this flashlight in 2020 shortly after being promoted to sergeant. I didn’t use it every day, but whenever I did, it performed flawlessly — and I rarely had to recharge it. I left law enforcement in August 2024 and put all my gear, including this flashlight, into a storage box. I didn’t touch it again until October 2025 when I started working security. To my amazement, it powered on at full brightness — despite not being charged in over a year. The battery life and overall build quality are genuinely impressive. At this point, I don’t see myself needing another flashlight anytime soon… but if I ever do, it will absolutely be another Anker.

I'm a flashlight addict, or is it that I have a flashlight fetish? Heck, I dunno, but I added this flashlight to my sack o' 200+ flashlights because in a video about "the top ten flashlights in 2023" the Anker Bolder not only made the list, but the reviewer also said the Bolder was one of the few of the ten top models that tested to an honest 900 lumens (that be a bright flashlight). I was so pleased with this light bought a second one so both my e-bikes now have super bright "headlights." Tip: Although the battery appears built-in and non-removable, that's not accurate. The 18650 battery is user removable. Technique: twist open the top cap, which you do to access the micro-USB charging port. You will see a knurled cap. I had to use a pair of pliers to GENTLY twist the cap off. Doing that revealed that this light has a generic (no brand name) 18650 battery. That's a feature because that means you can take a few spare 18650 batteries with you in the SUV or on the boat and never be short on battery power. Not much else to say about the light. I did put some metal tape around the edge of the lens end. This to cover the jagged edge that's there for self-defense. I find that jagged edge more of a hindrance than anything else. I don't like that kind of edge because it is a hazard. Too easy for it to injure, for example, if it drops on to the floor and hits my dog's head, or cuts my foot open. No thank you. The beam on this light is bright and on its narrow focus throws a looooooooooooooooooooong distance. You will love that kind of performance, I guarantee. And overall, this is a quality-made light. It feels like a $100 flashlight (I know because I have a few of those). Bottom Line: I have a lot of Anker products bought over the past 15 years, including about 20 of their USB phone chargers (Highly recommend you check those out. They work very well.) So I bought this with confidence in the Anker name. Buy this flashlight guys, I bet like me, after getting your first one you will be buying another two or three.

Let me start off by saying this flashlight is a beast! From a solid build to brightness and everything in between. I will start with build. The weight is just right, not too heavy, but not so light you feel like you have to be gentle with it. I like the one handed focus adjustment for the beam. At fist I didn't think I would ever use this feature, but it comes in handy. If I am standing on my deck I can use it like a flood light to see my whole yard. If I want to see what is going on a block away and piss off my neighbors it will get the job done. Size wise, it does fit in my pockets with no trouble, however I would say that it is still too bulky to be used as an EDC light for those wondering. Most of the time it sits by my bed as an emergency light.The things I could get picky about for build would be that since it doesn't need to fit in my pocket they could have added a bit more texture to the handle for added grip. The other thing would be the add something to it to keep it from rolling away when laying it down on a flat surface. Moving right into brightness I will advise other people not to do what I did when it arrived and that was to look right at it and turn it on to see if it came with a charge. It did! Once I regained my vision I tested it out around the house and in my garage. The thing I like about it, besides being obscenely bright was the color of the light. It is a nice white light not one that has that odd yellow hue to it. Another nice function that Anker added is that it will remember the last setting you were on when you turn it on again without having to go through them all to find the setting you want. When it comes to making a quality battery Anker has got it down and the one in the flashlight is no exception. It does take a couple hours to get a full charge and as long as I am using low or medium brightness it has always lasted as long as I need it. I am sure if you're using it on high your battery time will be reduced significantly, but for around the house high is almost too much. The standby time seems to do well also. It can sit there for a month at a time and still has a great charge. This came in especially handy when we had a power outage that started at 9pm and lasted all night. I just grabbed the Anker flashlight off the shelf and could light up my whole room with it. I would recommend this flashlight to someone that is needing a solid emergency flashlight for around the house, to keep in your car, or for a B.O.B.. If you are looking for more of an EDC flashlight I would suggest looking at Anker's smaller 400 lumen flashlight. I hope this review will be helpful in your prepping needs.

I started using this light in 2018, and since then have bought three more, it is just that good for a $30 flashlight. Cheap enough that I can just have one in any place I might need it, my bedroom, my car, my toolbox, without having to look for it or go get it. This is not the best flashlight in the world, but in my opinion it stands far above others at a similar price point, I also have 2 Streamlight Strions (~$100 per light) and honestly I prefer the LC90 over them, as it has universal 18650 batteries, the ability to focus between flood and spot, and charges with a standard USB cable. Brightness: - 5/5 - Ranges between too bright for some situations, and dim enough to not blow out your night vision Durability: - 5/5 - After 3.5 years across 4 lights, in varied conditions, they have all functioned without issue Usability: - 5/5 - The only part of this light that may need servicing is the battery, and I am still on the original for all of the lights, and it uses an easily sourced 18650 cell unlike some brands with proprietary batteries Battery Life: 5/5 - I do not know how long this light will last for on a full charge, I top it off after each use normally, and have used it for up to 5-6 hours in a day without any perceptible loss of brightness, the parasitic drain also seems to be fairly low, as the one in my car has sat in there for 6 months at a time without being used or charged, from as low as 28 degrees in the winter, to 170 degrees during the texas summer, and its still going strong, which is doubly impressive as that is my oldest one, purchased in 2018. Ultimately, if you want an everyday flashlight that is bright, flexible, and easy to use, and costs 50-70% less than other lights with the same capabilities, go no further, this is the one. Thanks Anker for your continued commitment to making quality electronics.
