You get more than what you pay for

I bought this without doing extensive research because Anker rocks. Their power banks are the bomb and pretty much everything I've gotten from them so this excited me. It does work exactly as advertised- I just didn't realize it had design shortcomings before buying it. Pros USB rechargeability at this price point is pretty awesome and the battery life seems awesome, assuming it's actually that 3... mah they advertise. Update... the battery life is awesome. Being water proof, this bright, USB rechargeable, and having a mode memory is a good thing. That and the scalloped bezel is nice. The battery is replaceable, tho I haven't tried it. The light spread and pattern is great. Its comfortable to hold too. It performs very well. I have dropped it several times on rocks and concrete.. not a scratch! Cons. FIX THE MODES!!! It sucks that you have to cycle through strobe and sos everytime, that needs to be locked out accessible through specific button command. The button also needs soft clicking / partial actuation usability. I don't like that the USB port is on the back as opposed to the side, making the button tiny. NO! it's too clicky and just sounds cheap. Still feels pretty good. The runner is soft. The Gnurling or "antislip" surface is a joke. It needs to be more aggresive, meaning cut deeper and with wider gaps and slightly sharper edges.. its uniquely shaped but not very functional for not slipping. Lastly... the pocket clip and material all around seems thin. It feels strong however. It just doesn't look very nice. Not that that matters at this price point. I'm holding this light to foursevens standards, which is a problem I suppose because it's a 20$ light. Oh yeah.. no lanyard hole and the pocket clip isn't removable... poo All that garbage said, the only real problem I have is the modes, which is what I'm removing the star for.. and the weird button. but I already have a smaller EDC light, so this will be my dedicated spot light/ brighter defense light. This light is really good for the price still, so of you only want to use it for one mode most of the time, it's not even an issue other than having to hold the light to turn it off to forego cycling through all the other modes. I want them but not that bad... theyre not worth all the clicking... so either remove modes to keep it cheap and less annoying or program it right.

Anker -> Sweet Spot 'Tween Quality and Price -- Great Value -- Wish It Had a Zoom

I bought this and another Anker at the same time. I am sold on this brand. I had gone from $3 to $8 flashlights and was still getting lights that didn't last. But when I found out "real" flashlights could be $60 and up, I couldn't afford that. I ended up buying Anker because I had purchased other products by them and was pleased with their quality. This flashlight does not disappoint. Their promos read like the more expensive brand names, but their pricing seems lower than top brands. That is what I believe I got with this light. I also have a Fenix penlight that cost $10 more. The Anker is a little bigger and brighter and seems every bit the quality (though, I am not a flashlight expert) as the Fenix. I do like zoomable flashlights, but this does not zoom. It is bright and has a tight narrow beam that gives it a good throw (ie, how far away it lights) outdoors. Because of its narrow beam, it is brighter than my Anker 900 lumen tactical flashlight...not because it's brighter, but because the beam has a narrower focus. To me the tight focus is suited to outdoors. The narrow focus is less useful indoors.

Durable, reliable, and bright.

I use flashlights in the fire service. This is one tough little light that has held up well. 3 brightness levels, strobe (which is blinding) and the SOS modes are perfect. the switch is well protected and its rubber cover is not likely to get rubbed off ( like my last flashlight) . I have a handfull of ANKER products and I love their durability and quality. I will be getting another one of these soon. I can say ANKER has gained my trust in their products. Con: that little rubber switch i mentioned, its too small to operate with my gloves on. with those gloves about the only thing they can handle well are hoses and axes. So PROS:99% CONS: 1% I dont care much for the 1% anyway

Perfect for some. Leaves a little to be desired. You'd have to pay a LOT more to get much more.

I love it. I especially love it for the price. I would never carry this light because it's diameter increases near the emitter, the button is too small, and it has too many modes. It was however perfect for my dad who has needed a good flashlight for some time now. I was worried he would probably lose them on me so I never wanted to give him one of my $150+ snobby flashlights. I recently got one of the smaller anker lights and was impressed with it and gave him that but it's a pain for him to have an 18650 charger in his rv or try to find cr123a batteries in strores so as soon as I saw this as a lightning deal for $16 I knew I had to get it for him because of the micro usb charging. Like my smaller anker light it has a tight "hotspot" and a dimmer spill than I would like but it's still very bright and has excellent throw. Also it's worth noting that I think Anker is underrating the lumens as it is rated at 400 lumens but seems to be on par with 800 lumen flashlights from olight and surefire. My one 1050 lumen flashlight is definitely brighter and it's medium 400 lumen setting appears dimmer than the Anker. The button is very small due to the charging port being next to it but for what he will use it for that's actually a good thing because it will have less of a chance of getting turned on bouncing around in a box or bag in his rv or truck. The thing I like least about the light are the numerous modes. High, Med, Low, Strobe, SOS, off by button presses and a long press of the button will turn the flashlight off. That's kind of a lot to toggle through and I never use anything but high and medium on my other flashlights. If you turn it off with a long press it will remember the mode it was in when you turn it on again. I can't complain though. The price is SO good especially considering it has an internal battery and charger. My "snob" lights were all $150+ and batteries and chargers were sold separately and they are only a little bit better than this light (subjectively). It's just a great, solid, simple light without any hassle to get all the lumens at a great price.

Best flashlight for the money

Put this flashlight thru 8 months of abuse before the switch went bad. Hot attics, damp or wet crawl spaces, rain and snow, dropped off of a ladder, and left in a hot van over the weekend in the middle of the summer. Battery runs forever before actually dying, I’d usually recharge it after the brightest setting got dim, which was about once every week or two. It pretty much paid for itself after 3 months of not buying AA or AAA batteries. I just used my phone charger in my car to charge it. Customer service was spot on. Had a new flashlight in my mailbox in less than a week after contacting them about the switch. Even supplied a return label to send the old one back . Big fan of Anker products. I’ve got Two flashlights, 5 phone charging cables,and 2 car chargers.

Can't go wrong with a trusted brand.

I've become an advocate for Anker. Recommending it for power banks, solar panels, USB cables, wireless Qi chargers, etc. This flashlight was available for Prime Day, so I jumped on it. "Anker item on sale? Buy now!". I don't believe in having too many lighting sources for emergency situations. And someone always manages to lose a flashlight I lend them when camping. Some people collect knives, other stamps, I collect practical tech/gear for emergency situations. Ex: When severe weather knocks out power for the neighborhood, my home is lit up and I'm watching Netflix via WiFi off my desktop with a Back-UPS. The light is plenty bright. The functions are practical. And for the price, I couldn't pass it up. My one quip would be the button location. I prefer the traditional tac-light placement on the end opposite of the bulb. I haven't tested it fully, but thus far it seems to hold a charge fairly well. I haven't touched it in 2 months, then let it sit on the high beam. It lasted an hour until I could visibly notice a decrease in the lmns it was putting out. Another hour and it dimmed more. Then the following 2 hours, it was bright enough to light the interior of a tent (or in my case, a dining room with white walls).

Anker LC40 is a 5 Star light.

Anker LC40 Flashlight goes way in. This light was already used about 10 times in 1 day I have it in my pocket and the light is awesome and hooks up to my Powerline II+ cable than right up to the Anker surge protector to charge. I have the 1 foot Powerline so it charges fast and I took the stock cable and gave it to the youngsters. Great light probably easily the best I have ever owned in my life I am 40 in September.

Brightest flashlight, especially for its compact size.

Incredibly bright, durable, easy to use flashlight. Wish it was possible to disable the strobe and SOS modes that I will never use. Useful Product Features: -Waterproof. It actually works underwater, just make sure the rubber cover on the back is tightly closed. -Rechargeable. Anyone with a smartphone charging brick can charge this, as it comes with the cable you need. -Very Bright. See the picture I posted. The photo is of the light on the brightest setting shining up a road at 2 am, pitch black sky with very little light pollution. Enough said. It easily lights up the entire road just as well as a car headlight beam. The one feature I wish was more advertised is that if you are on any mode with the light on, and you press and hold the power button, the light will turn off and you will not have to shuffle through all the modes. This is incredibly useful when all I want is a 1 mode flashlight.

The most used (out of many) flashlight I own

I have been collecting flashlights for a few years now. I use them daily for work as well as nightly when I walk my dog. The Anker Boulder is a tough light, it's super bright, it stays charged for a long time, and it's easy to charge. Some of my lights have removable lithium batteries that have to be charged in a separate charger, but the Boulder has a micro usb plug built in to the tail cap. I use it for at least 15 minutes every single night and I MIGHT charge it once every two months. I've dropped it in the rain, in the snow, and on concrete, and it has never once given me a problem. I am planning on buying a second one to keep in my vehicle, especially since I can charge it in my car with a cell phone charger. I've owned some expensive flashlights in the past, and this $16 light out performs them all with it's ease of use and durability.
