The COAST Slayer is a rechargeable EDC flashlight built around a simple idea: give you flood, spot, and a shortcut to your favorite setting without turning the user interface into a memory test. It is small enough for pocket or bag carry, bright enough for real outdoor use, and durable enough for emergency kits, camping gear, vehicle use, and normal everyday tasks.
National Preparedness Month was the reason I first shared it, but this is not only a 72-hour-kit flashlight. The Slayer is the kind of light that can live in a pocket, purse, backpack, nightstand, glove box, or camping bin and still get used outside of emergencies.
COAST Slayer Review: Quick Verdict
The COAST Slayer is worth considering if you want a rechargeable EDC flashlight with simple controls, USB-C charging, a deep-carry clip, dual flood and spot lenses, and a useful Beamsaver Memory Mode. It is not trying to be the brightest flashlight COAST makes, and it is not a tiny keychain light. Instead, it lands in the middle as a practical daily-use light that also makes sense for camping, power outages, and emergency kits.
The 1,150-lumen Turbo mode is helpful when you need a quick burst of extra light, but the more useful features are the separate flood and spot modes, the shortcut button, the pocketable size, and the IP67-rated aluminum body.
Best fit: The Slayer makes the most sense for someone who wants a rechargeable EDC flashlight with easy controls, useful output levels, a durable body, and enough versatility for home, vehicle, camping, and emergency use. Check the current COAST Slayer price.

COAST Slayer Features
Inside the aluminum body is a ZITHION rechargeable battery. Charging is handled through a USB-C port hidden under a rubber cover at the tail end of the light. At the opposite end are dual lenses for spot and flood output. Up top are the two control buttons, and on the side is a sturdy deep-carry clip.
Color options include silver, blue, red, and dune, which is a variation of FDE. My evaluation copy is the low-key silver version with a black clip. The overall shape is slim, easy to hold, and more interesting than a basic round flashlight tube.
Beamsaver Memory Mode
The controls are one of the best parts of the COAST Slayer. The forward button cycles through the different lighting modes. There is no need to memorize a complicated sequence of taps and long presses. I have other lights with all sorts of features hidden behind button combinations, and if I cannot remember them, my wife certainly will not.
COAST keeps this one simple. The rear button is used to memorize your favorite mode. Cycle through the settings, stop on the one you want, and hold down the rear button. Once it flashes, that setting is saved. From there, you can access your preferred mode quickly with the rear button while still using the front button for the other settings.
For me, that shortcut makes the most sense with low flood. It gives enough light for close work without blasting the room, ruining night vision, or waking someone up.
Flood, Spot, and Turbo Output
The Slayer gives you five output options across its two lenses. The flood lens has low, medium, and high settings at 42, 205, and 380 lumens. The spot setting provides 540 lumens for reaching farther across a yard, driveway, campsite, or dark room. Turbo combines spot and flood for a temporary 1,150-lumen burst.
That mix works well for real use. Flood is better for close work, walking, checking under furniture, or lighting up a small area. Spot is better for distance. Turbo is there when you need more light right now, but it is not the setting I would use most of the time.
For a larger light with more output, power-bank capability, and AAA backup, see my COAST XP20R flashlight review. For area lighting during camping or power outages, the COAST EAL40R rechargeable lantern makes more sense than a handheld flashlight.
COAST Slayer as an EDC Flashlight
I have never had a shortage of uses for a flashlight. Is the cat outside or under the bed? Use the memory button for low flood to check under the bed. No cat. Head out to the backyard, switch to high flood, and sweep the yard. Use the spot feature to check the overgrown weeds on the side yard. Still no cat. Back to low to check the dark corners of the upstairs closet. Our cat really did disappear.
Waking up in the middle of the night is another good use case. Instead of turning on a room light and waking up my wife, I can grab the Slayer and use the low flood shortcut. In one case, it turned out to be the other cat, who had dragged in a giant moth and was chasing it around the kitchen. I did not choose these pets.
It is also useful around the garage and house. Drop a socket while working on a car, need to peek into the attic, look under a sink, check inside the furnace, or scan the yard at night, and the Slayer is an easy light to grab. It is large enough to hold comfortably, but not so large that it becomes annoying to carry.
Styling and Pocket Carry
The shape is ergonomic, and the styling has faint firearms cues. Stacking the lenses vertically reminds me a little of a handgun barrel with a guide rod below it. The angled cuts on the side are also slightly reminiscent of slide serrations.
That does not make it a weapon light or tactical light. It just gives the Slayer more personality than a plain tube-shaped flashlight. Overall, it looks good, fits well in hand, and carries easily with the deep-carry clip.
Emergency Kit and Camping Use
Although the runtime is not designed for days of heavy use on high, the Slayer still makes sense for emergency and camping use. It is a flashlight, not a lantern, so the runtime is reasonable for the size. If we had a three-day power outage or a long weekend camping, I would expect it to be useful as long as I used the lower modes when possible.
USB-C charging also matters. I got tired of throwing away batteries a long time ago, and we have several portable power banks for recharging USB devices. Being able to recharge the Slayer from the same kind of setup is a practical advantage.
Durability is part of the appeal too. With an aluminum body, recessed lenses, sealed buttons, and an IP67 rating, the Slayer is built for rougher use than a cheap drawer flashlight. It is small enough to keep handy, but not so small that it disappears the first time you need it.
Pros and Cons
What I Like
- USB-C rechargeable battery
- Simple controls
- Useful Beamsaver Memory Mode
- Separate flood and spot lenses
- 1,150-lumen Turbo mode
- Deep-carry pocket clip
- Durable aluminum body
- IP67 dustproof and waterproof rating
- Good size for EDC, vehicle, camping, and emergency use
What Could Be Better
- Runtime is not ideal for extended high-output use
- The clip may be the weak point for some users
- Not as compact as a tiny keychain light
- Not as powerful or versatile as a larger emergency flashlight
I had no issues with the clip over a couple of weeks of carrying and use. If it did fail, my experience with COAST customer service gives me confidence that they would take care of it.

Final Thoughts on the COAST Slayer
