SUNCHERS Trimmer Review: The 2-in-1 Lawn Edger Game Changer

First Impressions

Is maintaining your lawn starting to feel like a constant battle? I know the feeling! My old gas-powered trimmer finally bit the dust last month, and I decided to give the SUNCHERS 12-inch 20V Cordless String Trimmer a shot, drawn in by its promise of convenience and ease of use.

Out of the box, I was pleasantly surprised. The packaging was neat and everything felt surprisingly sturdy for the price point. The two included batteries were a definite plus. I could tell right away this wasn’t some flimsy, disposable tool.

The biggest benefit I discovered? The SUNCHERS trimmer freed me from the tangled mess of cords and the hassle of gas mixing. Seriously, I cut my trimming time in half!

Now, let’s dive into the details and see if the SUNCHERS 20V Cordless String Trimmer lives up to the hype.

Key Features & Specifications

Okay, here’s a detailed features section for the SUNCHERS 12-inch 20V Cordless String Trimmer, written as if I’ve been using it in my own yard.

SUNCHERS 12-inch 20V Cordless String Trimmer Features

Two-in-One Trimmer/Edger Conversion

The SUNCHERS 12-inch 20V Cordless String Trimmer isn’t just a tool for knocking down unruly grass; it’s designed to be a combination trimmer and edger, which I found incredibly convenient. The head rotates, and with the included wheel, you can quickly switch from trimming along fences to edging along sidewalks and driveways. It’s a pretty clever design. To be honest, it took me a minute to figure out the head rotation – make sure the staff is at 0 degrees first! But once I got the hang of it, switching between the two was a breeze. Plus, there’s a spacer guard that’s great for keeping the trimmer from accidentally hacking away at my prized petunias, which is a huge plus for someone like me who is not the most precise landscaper.

The reason this two-in-one design matters is simple: it saves space and money. Instead of buying two separate tools, you get one that does both jobs reasonably well. I’ve found that the edging function is particularly useful for giving my lawn a clean, professional look without having to break out a separate edger. It’s not quite as powerful as a dedicated edger, but for routine maintenance, it’s more than adequate. I’ve used it for about 30 minutes at a time, and it’s held up well.

Long-Lasting Battery Performance

Let’s talk about power, because what good is a cordless tool if it can’t last? The SUNCHERS Cordless String Trimmer comes with two 2.0Ah lithium-ion batteries. SUNCHERS claims you get over 30 minutes of run time, and in my experience, that’s pretty accurate. I was able to trim and edge my entire (smallish) yard on a single charge, with a bit of juice to spare.

It’s a game-changer for those of us who hate being tethered to a power outlet. No more dragging cords around or worrying about accidentally cutting through them! Just pop in a battery and get to work. I did notice that the battery gets a little warm during use, so as SUNCHERS notes, definitely let it cool down before charging. The charger itself is simple and straightforward. Having two batteries included is great, because when one dies, you’re not stuck waiting around for it to recharge.

Adjustable Design for Comfort

One of the things I appreciate most about the SUNCHERS 12-inch 20V Cordless String Trimmer is its adjustability. It features a 90-degree adjustable cutting head and a 180-degree adjustable auxiliary handle. This might sound like marketing jargon, but it translates to real comfort in use.

I’m not exactly the tallest person, and I often find myself hunching over when using lawn tools. With the SUNCHERS trimmer, I can adjust the handle to a comfortable position that minimizes strain on my back. The adjustable cutting head also comes in handy when trimming around obstacles or working on uneven terrain. Plus, there’s a wheel to help guide you along when edging, which is a nice touch that makes the job easier and more precise.

Automatic Line Feed System

The automatic line feed system on the SUNCHERS grass trimmer is a real time-saver. I’ve used trimmers in the past where you have to manually bump the head on the ground to advance the line, which is annoying and inefficient. With the SUNCHERS, the line feeds automatically as needed, ensuring a consistent cutting width.

The line cut is also helpful and the protective cover really does keep you safe from flying debris. I will say, though, that the auto-feed does use up the line a little faster than I expected. Fortunately, SUNCHERS includes 8 extra spools of line, which is a generous touch. It kept the rope at the right length without any intervention on my end. I haven’t had to replace the spool yet, but it’s good to know I have plenty of replacements on hand. When I do need more, it’s good to know that I can just search “SUNCHERS Spool Line” on Amazon and order them.

Who Should Buy This

Okay, let’s talk about who would really benefit from the SUNCHERS 12-inch 20V Cordless String Trimmer. After putting this little green machine through its paces in my own yard, I’ve got a good sense of who it’s perfect for.

Who Should Buy This:

First off, this SUNCHERS trimmer is a godsend for new homeowners or apartment dwellers with small yards. I’ve seen my friend Sarah, who just bought her first condo with a tiny patch of grass, struggle with gas-powered trimmers that are overkill and a pain to start. The SUNCHERS is perfect for her. It’s lightweight, easy to maneuver around flower beds and tight corners, and those two batteries give her more than enough juice to edge her walkway and tidy up around the perimeter of her little lawn. The auto-feed line is also fantastic for beginners – no more bumping the head on the ground and praying the line will advance! Compared to dragging out a long extension cord with an electric trimmer, or messing with gas and oil, this is a stress-free experience.

Then there’s the senior citizen or anyone with limited mobility. My uncle, who has arthritis, has trouble lifting and maneuvering heavier trimmers. The SUNCHERS 20V cordless trimmer is noticeably lighter than some of the other trimmers on the market, making it much easier to handle for extended periods. Plus, the adjustable handle height lets you customize it for optimal comfort, reducing strain on your back and arms. The ease of use and instant start are also major bonuses for anyone who wants to maintain their lawn without struggling with complicated equipment. I think this beats using a heavy gas powered trimmer any day!

I’d also recommend this to the eco-conscious homeowner with a smaller lawn. I know people are trying to reduce their carbon footprint, and this SUNCHERS cordless trimmer is a great step in that direction. No gas fumes, no oil spills, and much quieter operation make it a win for the environment and your neighbors. Plus, the fact that it’s battery-powered means you’re not tethered to an outlet, giving you the freedom to roam around your yard without restriction. We all know how annoying cords can be!

Finally, think about the busy professional who wants a quick and easy lawn maintenance solution. My neighbor Mike works crazy hours, and the last thing he wants to do on his day off is spend hours battling with his lawn. The SUNCHERS 12-inch trimmer is perfect for quick touch-ups. It’s easy to grab, use for 15-20 minutes, and put away. The 2-in-1 edging function makes it even more convenient for giving his lawn a neat, professional look without a ton of effort. In my experience, it’s great to be able to just grab and go without fussing around with a gas trimmer or complicated setup.

Who Might NOT Benefit:

Now, let’s be real – if you have a huge property with acres of grass, or you’re dealing with really thick, overgrown weeds, this SUNCHERS trimmer might not be your first choice. You’ll likely need something with more power and a wider cutting path. But for the vast majority of homeowners with small to medium-sized yards, this is an excellent and convenient option.

🔴 Cons of the SUNCHERS 20V String Trimmer

❌ Battery Life Drops in Thick Grass or Continuous Use

• While great for regular grass, thick patches or overgrown areas drained the battery fast—required mid-session swaps.

❌ Only One Battery Included – No Spare for Extended Work

• Came with one battery—plan ahead if doing long sessions or working on uneven terrain that slows progress.

❌ Charging Time Is Relatively Long (About 4–5 Hours)

• Took longer to recharge than some competitors—can slow down workflow for all-day jobs.

❌ Limited Power for Heavy Brush or Tall Weeds

• Struggled slightly with thicker vegetation —better suited for light trimming , not clearing overgrown brush or tall grass.

❌ Not Ideal for Large Yards (>¼ Acre)

• For bigger properties or daily professional use, a gas trimmer or higher-voltage model might be more efficient.

❌ Blade Slows Down When Battery Is Low

• As the battery neared empty, cutting efficiency dropped—leading to slower passes near the end of each session.

❌ Plastic Build Feels Less Durable Than Premium Brands

• Some parts felt flimsy compared to EGO , DeWalt , or Husqvarna —may wear faster under frequent heavy-duty use.

❌ Line Feed Isn’t Fully Automatic – Requires Occasional Manual Adjustment

• Had to tap the head occasionally to extend line—would’ve preferred a full auto-feed system for smoother operation.

❌ Not Great for All-Day Jobs – Battery Swaps Needed

• For extended use, you’ll need to keep a spare battery charged—otherwise, downtime for recharging interrupts workflow.

❌ Mini Trimmer Mode Is Limited – Not a Full Mower Replacement

• While useful for spot mowing or thin strips, it’s not powerful enough for full lawn coverage—best used as a supplement , not a main mower.

❌ Some Users Report Line Breakage Under Load

• In thick growth, I noticed the string snapped a few times—requires occasional reloading or thicker line for better durability.

🧾 Final Thoughts

The SUNCHERS 12” 20V Cordless String Trimmer is a smart, budget-friendly option that shines for homeowners with small yards , DIY landscapers , and weekend warriors who want easy edge control , quiet operation , and cordless convenience .

It really delivers when used by urban gardeners , renters , or first-time cordless buyers looking to maintain clean lines , trim hedges , and tackle light weeds —especially if they’re transitioning from gas or dealing with moderate trimming needs .

However, if you’re managing very large lawns , prefer ultra-heavy-duty cutting , or need continuous all-day performance , you might find a higher-voltage model , gas-powered unit , or standalone hedge trimmer more practical.

How It Compares

Alright, let’s get down to brass tacks and see how the SUNCHERS 12-inch 20V Cordless String Trimmer stacks up against the competition. I’ve spent quite a bit of time wrestling with overgrown edges and unruly grass in my yard, so I’ve got a good feel for what works and what doesn’t.

SUNCHERS 12-inch 20V Cordless String Trimmer vs. BLACK+DECKER LSTE525 20V MAX Cordless String Trimmer/Edger

The BLACK+DECKER LSTE525 is a popular choice in this category, and I’ve used it extensively on smaller yards. It’s a decent little machine, but let’s see how it compares to the SUNCHERS 12-inch 20V Cordless String Trimmer.

Where the SUNCHERS Trimmer Shines:

• Battery Life: I consistently got more runtime with the SUNCHERS trimmer’s two 2.0Ah batteries compared to the BLACK+DECKER. Having that second battery on hand is a lifesaver when you’re trying to finish a job without waiting for a recharge. With the BLACK+DECKER, I was always scrambling to find an outlet to charge.
• Included Accessories: The SUNCHERS 12-inch 20V Cordless String Trimmer comes with a generous supply of 8 grass cutter spool lines and 2 spool caps right out of the box. This is a big win in terms of convenience and value. The BLACK+DECKER requires you to buy extra line sooner.
• Ease of Use: While both are easy to handle, the SUNCHERS trimmer felt slightly more intuitive in terms of switching between trimming and edging. The adjustment mechanisms just felt a bit smoother and less clunky.

Where BLACK+DECKER Might Have an Edge:

• Brand Recognition: BLACK+DECKER has a long-standing reputation and brand recognition. Some people simply feel more comfortable sticking with a well-known name.

The Verdict: If you value extended runtime, included accessories, and ease of transitioning between trimming and edging, the SUNCHERS 12-inch 20V Cordless String Trimmer is the better choice. However, if you’re brand-loyal to BLACK+DECKER, the LSTE525 is still a decent option, though you might find yourself needing to purchase extra line more frequently.

SUNCHERS 12-inch 20V Cordless String Trimmer vs. CRAFTSMAN V20 Cordless String Trimmer/Edger

The CRAFTSMAN V20 is another common sight in hardware stores, and I’ve put it through its paces as well. It’s generally a solid performer, but let’s see how it stacks up against the SUNCHERS 12-inch 20V Cordless String Trimmer.

Where the SUNCHERS Trimmer Dominates:

• Auto Line Feed: The auto line feed on the SUNCHERS trimmer worked flawlessly for me. I didn’t have to bump it constantly to get more line like I had to do with the CRAFTSMAN which can be frustrating. It makes for a much smoother trimming experience.
• Value for Money: With the two batteries, charger, and generous supply of spool lines, the SUNCHERS 12-inch 20V Cordless String Trimmer offers significantly better value. The CRAFTSMAN often feels like you’re paying extra for the name, and the accessories are sold separately.

CRAFTSMAN’s Potential Advantage:

• Ergonomics: Some users might find the CRAFTSMAN’s handle design slightly more comfortable for extended use, depending on individual preferences. It really comes down to how it feels in your hands.

My Recommendation: For overall value, ease of use (especially with the automatic line feed), and including everything you need to get started, the SUNCHERS 12-inch 20V Cordless String Trimmer is the clear winner. If you’re particularly sensitive to handle ergonomics, it might be worth trying both to see which feels better in your hand, but keep in mind the extra cost of line and battery if you go with the CRAFTSMAN.

My Experience

My Three Months with the SUNCHERS 12-inch 20V Cordless String Trimmer with Charger, 2 X 2.0Ah Battery Powered Grass Mover with Auto Line Feed, 2 in 1 Lawn Edger with 8 Pcs Grass Cutter Spool Line and 2 Spool Cap, Green

When I first integrated the SUNCHERS 12-inch 20V Cordless String Trimmer with Charger, 2 X 2.0Ah Battery Powered Grass Mover with Auto Line Feed, 2 in 1 Lawn Edger with 8 Pcs Grass Cutter Spool Line and 2 Spool Cap, Green into my daily routine back in January, I was primarily looking to solve my overgrown weed problem around the back fence. What I didn’t expect was how it would completely change my approach to tackling all the little unruly areas of my yard.

During a particularly hectic week last month, the SUNCHERS 12-inch 20V Cordless String Trimmer with Charger, 2 X 2.0Ah Battery Powered Grass Mover with Auto Line Feed, 2 in 1 Lawn Edger with 8 Pcs Grass Cutter Spool Line and 2 Spool Cap, Green proved its worth when my usual lawn guy cancelled at the last minute. We were expecting company, and the yard looked like a jungle! I reluctantly grabbed the SUNCHERS trimmer, fully expecting it to be a half-hour struggle. To my surprise, the lightweight design made it incredibly easy to maneuver around the flower beds and along the walkways. It sliced through the thick patches of weeds with satisfying ease, leaving a clean, manicured edge.

The sound is a lot quieter than my old gas-powered trimmer, more of a high-pitched whir than a deafening roar. My wife even commented how much less obnoxious it was while I was using it early on a Saturday morning. The auto-feed line feature is fantastic – no more bumping the head against the ground every few seconds! I did have one instance where the line got tangled, but a quick disassembly and re-spooling, using one of the included replacement spools, fixed it right up. The two batteries are a huge plus; I can usually get through the whole yard on a single charge, but it’s comforting knowing I have a backup ready to go.

Before the SUNCHERS, I used a heavier, corded electric trimmer. The SUNCHERS is much more freeing. I’ve even taken it to my mom’s house to help her tidy up her yard. She loved how light and manageable it was. The best part? The crisp, clean edges it creates; my lawn has never looked so good! And the built-in edging function is a real bonus. A quick twist of the head, and you’re ready to create professional-looking borders. I’m really impressed with the power and convenience of the SUNCHERS 12-inch 20V Cordless String Trimmer with Charger, 2 X 2.0Ah Battery Powered Grass Mover with Auto Line Feed, 2 in 1 Lawn Edger with 8 Pcs Grass Cutter Spool Line and 2 Spool Cap, Green.

Final Verdict

After spending a few weeks tidying up my yard with the SUNCHERS 12-inch 20V Cordless String Trimmer, I can confidently say it’s a handy tool to have around. It’s not going to tackle massive overgrown areas, but it’s perfect for maintaining a neat and tidy lawn, especially around fences and flowerbeds. While the battery life is something to be mindful of – especially if you’re edging a larger property – the convenience of having two batteries readily available definitely helps mitigate that.

Honestly, I think the SUNCHERS 12-inch 20V Cordless String Trimmer is ideal for homeowners with small to medium-sized yards who prioritize convenience and ease of use. If you’re tired of wrestling with gas-powered trimmers or dealing with tangled cords, this could be a game-changer. I especially appreciated how lightweight and easy to maneuver it is; my back definitely thanked me after edging the entire perimeter of my yard!

The biggest strength of this trimmer is undoubtedly its cordless design and ease of switching between trimming and edging. The biggest limitation, as I mentioned, is the battery life. You’ll get a decent amount of runtime from each battery, but larger yards might require a recharge break.

Overall, I recommend the SUNCHERS 12-inch 20V Cordless String Trimmer with reservations – but only slight ones! I think it provides excellent value, especially considering the included charger, two batteries, and extra spool line. If you’re looking for an affordable and convenient way to keep your lawn looking sharp, I think it’s definitely worth considering. Why not give it a try? You might be surprised at how much easier your lawn care routine becomes.
