If you’re looking for a capable and affordable string trimmer to handle your yard, you’ve likely come across a popular model. This Black and Decker NSW18 review aims to give you a clear, practical look at what this cordless tool can and cannot do.
It’s a lightweight, 18-volt trimmer that promises ease of use for typical suburban tasks. Let’s see if it lives up to the hype and is the right fit for your garden shed.
Black and Decker NSW18 Review
This section provides a detailed breakdown of the trimmer’s key features and overall performance. We’ll cover its power, runtime, cutting ability, and how it feels to use over time.
Key Features and Specifications
Before we get into the hands-on experience, here’s a quick glance at the core specs of the NSW18:
* Power Source: 18V Lithium-Ion battery (works with Black+Decker’s 18V system)
* Cutting Swath: 12 inches
* Line Feed: Automatic Feed Spool (AFS)
* Shaft Type: Straight shaft
* Weight: Approximately 7.3 lbs (without battery)
* Included: Usually sold as a tool-only unit, but often bundled in kits.
Performance and Power in Real Use
The NSW18 is designed for light to medium-duty trimming. It’s not a commercial-grade brush cutter, and it performs best when used within its intended scope.
* On Grass and Weeds: It excels at trimming lawn edges and cutting down soft, young weeds. The 12-inch cutting path is sufficient for most perimeter work.
* On Tougher Growth: When you encounter thick, woody weeds or overgrown grass, you’ll need to slow down and make multiple passes. It can struggle a bit, which is expected for its class.
* Battery Life: Runtime depends heavily on the battery Ah rating you use. A 1.5Ah battery might last 15-20 minutes of continuous use in average grass, while a 4.0Ah or 5.0Ah battery extends that significantly. For a small to medium yard, having a second battery is a smart idea.
Design and Ease of Use
This is where the NSW18 often wins people over. Its design prioritizes user comfort.
* Lightweight: It’s very easy to carry and maneuver, reducing arm fatigue during longer sessions.
* Straight Shaft: The straight shaft design is more comfortable for taller users compared to curved-shaft trimmers, as it provides better reach without excessive bending.
* Automatic Feed Spool (AFS): This system is a major plus. It automatically advances the trimmer line when it detects you tapping the head on the ground. This means less interruption and no bumping to feed line manually.
Assembly and Maintenance
Getting the trimmer ready is straightforward. Usually, it involves attaching the shaft, installing the guard, and loading the trimmer line spool. The manual provides clear diagrams. Maintenance is minimal: keep the air vents clean, check for debris wrap-around after use, and store the battery properly.
Loading the Trimmer Line: A Simple Guide
Even with AFS, you’ll eventually need to reload the spool. Here’s how:
1. Press the tabs on the sides of the spool head to remove it.
2. Remove any old line remnants from the spool.
3. Find the center of your new trimmer line and insert it into the anchor hole in the spool.
4. Wind the line tightly and evenly onto the spool in the direction indicated by the arrows.
5. Feed the loose ends through the eyelets on the spool head.
6. Re-attach the spool head to the trimmer until it clicks into place.
Pros and Cons: A Balanced View
No tool is perfect. Here’s an honest summary based on extensive use.
Pros:
* Very lightweight and easy to handle.
* Automatic line feed works reliably, saving time and frustration.
* Quiet, emission-free operation (no gas or fumes).
* Excellent value for money, especially if you already own compatible 18V batteries.
* Low maintenance compared to gas trimmers.
Cons:
* Power is limited for heavy-duty tasks like clearing dense brush.
* Battery life with smaller batteries may require swaps for larger yards.
* The cutting head can sometimes be prone to tangling if you hit very thick vegetation.
* It’s not the most powerful option availible, so setting expectations is key.
Who Is The NSW18 Best For?
This trimmer is an ideal match for certain gardeners. You’ll likely be happy with it if:
* You have a small to medium-sized suburban yard.
* Your main tasks are edging lawns, trimming around flower beds, fences, and trees.
* You value a lightweight, easy-to-start tool over raw power.
* You already own other Black+Decker 18V tools (so you can share batteries).
* You want a cordless tool without the hassle of gas mixing and engine maintenance.
Conversely, you might want to consider a more powerful model if:
* You have several acres of land or very rough, overgrown areas.
* You need to frequently clear thick brambles or saplings.
* Runtime is critical and you don’t want to manage multiple batteries.
Tips for Getting the Best Results
To make your NSW18 work even better, follow these simple tips:
* Use the correct line. A 0.065-inch diameter round line is standard; avoid overly thick lines that can strain the motor.
* Keep your battery charged. Lithium-ion batteries last longer if you don’t store them fully depleted.
* Use a pendulum motion when cutting. Sweep the trimmer from side to side for an even cut.
* Clean the trimmer head after use, especially if you’ve been in wet or seedy grass.
* For thicker spots, take your time and let the tool do the work—don’t force it.
Frequently Asked Questions (FAQ)
Does the Black and Decker cordless trimmer come with a battery?
Often, it is sold as a “tool-only” product. You must check the product listing carefully. Many retailers offer it in a kit that includes a battery and charger, which is a great value if you’re new to the platform.
What is the warranty on the NSW18 string trimmer?
Black+Decker typically offers a 2-year limited warranty for their tools. It’s always best to keep your receipt and register the product online for confirmation.
Can I use a higher Ah battery for longer runtime?
Absolutely. Any Black+Decker 18V Lithium-Ion battery will work. Using a 4.0Ah or 5.0Ah battery will significantly extend your trimming time between charges compared to a standard 1.5Ah battery.
How do I troubleshoot if the line won’t feed?
First, ensure the spool is installed correctly and isn’t jammed. Often, the issue is that the line is too short to reach the cutting head. Tap the head firmly on the ground while the tool is running at high speed. If that fails, disassemble the head to check for tangles or a worn-out spool.
Is the Black Decker trimmer powerful enough for my yard?
For regular lawn maintenance—edging and trimming grass and soft weeds—it is generally powerful enough. If your yard has consistently thick, woody growth, you might need a more powerful brushless or gas-powered model.
Final Verdict and Recommendation
The Black and Decker NSW18 is a solid, no-fuss cordless string trimmer that does its job well within its designed limits. Its lightweight build, reliable automatic line feed, and ease of use make it a winner for routine yard maintenance. The value is particularly good if you’re already invested in the 18V battery ecosystem.
However, its limitations with heavy growth are real. It’s a precision finishing tool, not a land-clearing brute. If your needs align with light-to-medium duty trimming and you appriciate a simple, effective tool, the NSW18 is an excellent choice that will serve you reliably for seasons to come. Just be sure to have a spare battery on hand to finish the job without pause.
