NiWalker N50S Flashlight Review: An EDC Flashlight with 2 Crazy Features

The NiWalker N50S is a compact rechargeable flashlight that can switch between a short one-battery setup and a longer configuration with a larger battery. That flexibility makes it an appealing everyday-carry option. After using it around the house, including a lights-out stairway test, I was impressed by its solid build, simple controls, and strong output. It is a dependable flashlight that performs as expected, though most people will likely prefer leaving it in the larger, longer-lasting configuration.

What Is It?

The NiWalker N50S is a rechargeable LED flashlight designed for everyday carry, home emergencies, and general utility use. Its most unusual feature is the included extension tube, which lets it accept a larger removable battery.

Without the extension tube, the N50S has a short and chunky shape that is definitely different from the usual cylindrical flashlight. Add the extension tube and larger battery, and it becomes a more traditional handheld light with a longer grip and, presumably, longer runtime.

The version reviewed here has a blue aluminum body, but it is also available in other colors. The scalloped bezel gives it a slightly aggressive look, while the blue anodized finish makes it stand out from the sea of plain black flashlights.

What’s Included?

NiWalker includes a nice assortment of accessories with the N50S, so it is ready to use right out of the box.

• NiWalker N50S flashlight
• Extension tube
• Small removable battery installed in the flashlight
• Larger removable battery
• User manual
• Spare O-ring
• Lanyard
• USB-A to USB-C charging cable

I was pleasantly surprised to find that this EDC flashlight already had the smaller battery installed. The larger battery is packaged separately because it only fits when the extension tube is attached.

It is worth noting that the batteries charge inside the flashlight through its USB-C port. The included batteries don’t have a separate charging port.

Design and Build Quality

The N50S has an aluminum housing, which gives it a sturdy, substantial feel in the hand. This is not one of those featherweight plastic emergency lights that gets tossed into a drawer and forgotten. It has some heft, and it feels well made.

On the side of the body, a single round power button and a USB-C charging port are protected by a rubber cover. The port cover is a welcome feature because it helps keep dust out when you carry or store the flashlight.

The tail end does not have a switch. Instead, it has a small opening for attaching the included lanyard. The tail cap unscrews to access the battery compartment.

The front has a scalloped metal bezel surrounding the reflector and LED. It is a distinctive design detail, although it is more about looks than function for most everyday uses.

One truly unexpected feature is a small rotating ring near the head of the flashlight. It works a little like a fidget ring. It doesn’t seem especially useful on a flashlight, and I cannot think of a practical reason to spin it while using the light, but it is there if that sort of thing appeals to you.

Two Configurations, But One Clear Favorite

The N50S can be used in two forms. In its compact form, it uses the shorter battery and has a very short grip. To convert it, unscrew the flashlight, add the extension tube, install the larger battery, and screw the tail cap back on.

The process is easy, and the threaded parts go together without drama. That is good, because a modular flashlight is only useful if changing configurations doesn’t turn into a chore.

Still, I have to wonder how often people will actually use the short configuration. The extended version is more comfortable to hold, gives you more body to grip, and should provide better battery life thanks to the larger battery. The compact version is neat, but it feels more like an extra feature than the reason to buy this flashlight.

If your main goal is the smallest possible light, the short configuration may have some appeal. But for power outages, walks around the property, garage duty, or keeping a flashlight by the bed, I would install the extension tube and bigger battery and leave it that way.

There is a little bit of a caveat when it comes to charging the batteries. Notice anything particular in the image above? Look at the tip of the left USB-C cable. It’s significantly longer than the one on the right. I noticed the problem when I first tried to charge the battery. I didn’t bother using the cable that came with the NiWalker and noticed that charging didn’t begin. Then I grabbed the cable that came with the flashlight, and it worked fine. This could cause an issue if you misplace the cable…

Simple Controls and Useful Mode Memory

One of the things I like most about the NiWalker N50S is that it’s not overly complicated to operate. Some flashlights require you to memorize a whole secret handshake of taps, holds, and clicks just to get the mode you want. This one keeps it simple.

• A single click turns the flashlight on or off.
• Press and hold cycles through the regular brightness levels. (65 – 700 lumens)
• Double-click activates Turbo mode. (1750 – 1800 lumens)
• The flashlight remembers the last regular brightness level used.
• Hold the power button when off to go into Moonlight mode (10 lumens)

The regular modes include Moonlight, Low, Mid2, Mid1, and High. Long-press to cycle through them. Mode memory is handy because if you normally use a moderate setting, the flashlight returns to that level when you switch it back on instead of always blasting at maximum brightness.

Turbo works a little differently. Double-clicking accesses it immediately, but Turbo is not retained in memory. When you switch the flashlight off and then turn it on normally, it returns to the last standard mode. That makes sense because Turbo is best treated as a quick burst of maximum brightness rather than the default setting.

Brightness Levels in a Real-World Test

A flashlight can look bright when pointed at a hand or a desktop, but the more useful question is how well it illuminates an actual space. The N50S was tested in a dark stairway to see how the different output levels handle a situation like a nighttime power outage.

Moonlight mode is rated at 10 lumens. That sounds modest, but it is enough to see the stairs and navigate safely without flooding the entire area with light. This is the mode I would choose for checking a room at night, finding a path to the bathroom, or avoiding ruining your night vision.

Low mode is rated at 65 lumens and gives a much more useful pool of light for moving around the house. The stairwell, walls, railing, and landing are clearly visible, making it a practical setting for most indoor tasks during an outage.

From there, the N50S steps up to Mid2 at 175 lumens, Mid1 at 450 lumens, and High at 700 lumens. Each level visibly expands the illuminated area and brightens the stairway. The 450- and 700-lumen settings are more than enough for quickly checking a large room, looking into a dark yard, or when you want a lot of light immediately.

Turbo is rated at 1,800 lumens (with the larger battery). It is seriously bright, lighting the stairway with a broad, intense beam. Turbo is for moments when you need maximum output now, whether you are checking outside after hearing something, looking across a dark space, or trying to identify something at a distance.

The progression between modes is easy to see, and the practical test confirms that even the lower settings are useful. That is important. Maximum lumens are fun, but a flashlight also needs modes that are comfortable and usable for ordinary tasks.

Who Should Buy the NiWalker N50S Flashlight?

The NiWalker N50S is a good fit for anyone who wants a bright, rechargeable flashlight without a complicated user interface. It is especially appealing for home emergency kits, bedside tables, garages, workshops, camping gear, and everyday carry bags.

The removable batteries are another plus. Being able to replace a battery instead of the entire flashlight is always nice, especially for a light intended for emergency preparedness. The USB-C charging port also means you don’t have to hunt down a proprietary charging cable.

This flashlight is probably not the best choice for someone who wants an ultra-slim pocket light. Even in its short form, its head is fairly wide, and its styling is more substantial than minimal. It also may not be ideal for someone who has no interest in modular battery configurations, since the extension tube and fidget-style ring add features that some people may never use.

Final Thoughts

The NiWalker N50S flashlight is bright, solidly built, easy to recharge, and easy to operate. Its output range is useful, from a gentle 10-lumen moonlight mode up to a powerful 1,800-lumen Turbo mode. The mode memory and direct Turbo shortcut make it especially convenient for everyday use.

The modular design is interesting, but I’d recommend the longer configuration. It is more comfortable in the hand and makes the most sense if you want to take advantage of the bigger battery. The compact configuration is a fun option, but I do not see it as the main selling point.

Then there’s the need for the special USB-C cable that could cause issues if you lose it. Likewise, the fidget ring is unusual but not particularly necessary. Fortunately, it does not get in the way of what matters: this is a dependable, good-looking flashlight that works as advertised.

The NiWalker N50S Flashlight retails for $49.99; it is available from retailers including FlashlightGo and Amazon.
