Kobalt 24V Max String Trimmer Review: 2024

kobalt 14 inch trimmer head

The Kobalt 24V String Trimmer attachment system is not only a super powerful weed eater, but capable of carrying some great attachments like a dethatcher, edger, and tons more. 

Kobalt power head handle looking nice!

I got my hands on this Kobalt 24V string trimmer system and put it to work, testing it around my yard and cranking all the different attachments. 

I’ve tested a bunch of attachment capable string trimmer systems like this Kobalt 24V model and my favorite has been the EGO multi-head. These two both sell at Lowe’s and will be side-by-side if you are making a decision.

Bottom Line: The Kobalt 24V string trimmer attachment system is a surprisingly solid, versatile system that comes in at an unbelievably low price point. If you are looking for a great alternative to some pricier systems, this is the perfect option. You can grab it at Lowe’s for a great price.

Testing the Kobalt 24V Max String Trimmer system

Once I got the Kobalt 24V Max String Trimmer out of the box, assembling it was a breeze. This comes as a split shaft, meaning it is already assembled and folded in the box. You simply snap it into place and put on the debris guard (if you want) and you’re ready to go. Here was my experience using this trimmer.

The Kobalt 24V Max string trimmer has nice cutting power

The 14 inch cutting swath on the Kobalt 24V Max string trimmer system is what I call the “Goldilocks” zone. This cutting swath isn’t so large that it reaches commercial landscaping territory, demanding a ton of juice from the battery and motor. 

Replace that string!

But at 15 inches, the Kobalt 24V Max trimmer is extremely powerful for any residential job. One thing I always do when I get a new string trimmer is to change out the weed eater string from its stock version to the kind I personally made, called GrassKicker. We designed this to be durable, sharp, and highly visible. 

When it comes to weed eaters, cutting swath is synonymous with power. Once I had the new string on here, the full 15 inch length was an absolute monster and a huge upgrade. The Kobalt 24V string trimmer has enough power for just about any homeowner (unless you live in a dense forest or have > 2 acres of land). 

Kobalt’s 24V trimmer is super durable

One thing I love about Kobalt’s 24V Max series string trimmer system is that it comes with a brushless motor. I’ve written extensively about brushless motors on lawn tools and am a strong proponent of making sure you have a brushless motor.

Luckily, the Kobalt 24V Max string trimmer has one of these motors, making it highly durable, giving it more torque, and a long life. And with all battery powered weed eaters, the Kobalt trimmer has no maintenance at all on the motor and will fire right up whenever you simply press the button.

The rest of this string trimmer has a super solid build – something that shocked me given the relatively low price. But the construction on this, especially around where the triggers are, felt solid and reliable and like it could last me for several years. 

The Kobalt string trimmer attachment system is universal

My Kobalt 24V Max string trimmer just came with the multi-head and string trimmer head. Since this string trimmer system is universal, I had a ton of other attachments I could pop on easily from my experience with other attachment capable systems. 

I loved that I could easily pop on an edger attachment and have a beastly battery lawn edger. Then I could grab a hedge trimmer attachment and have an extended hedge trimmer. Attachment capabilities on this trimmer make it a Swiss Army knife tool that not only saves a ton of money, but makes storage way easier. 

One attachment that I got separately because I had never seen it before is the Kobalt Dethatcher attachment. And I got this attachment only because it seemed strange. Usually lawn dethatchers are oriented like push mowers, so imagining using this with one hand across my whole yard just felt…awkward.

Well my imagination was correct. This Kobalt dethatching attachment was definitely awkward haha. I could see this attachment being awesome for small areas but would go crazy if I did this all across my lawn.

The Kobalt 24V MAX battery system has tons of tools

One thing you need to be careful about before buying this kobalt string trimmer is the difference between 24V and 24V MAX. In many battery lines, these two are surprisingly and unfortunately INCOMPATIBLE. 

On the bright side, Kobalt’s 24V Max system is huge – spanning dozens of lawn tools and even more hand power tools. From an investment perspective – I love only having to buy one or two batteries and one charger. This declutters my garage and keeps costs down when I buy the tool-only version of other tools. 

The Kobalt 24V Max leaf blower is a great addition to their lineup.

Kobalt 24V Max string trimmer system is inexpensive compared to others

This string trimmer sells exclusively at Lowe’s (just like all Kobalt stuff). At under $200 for the system and weed eater attachment plus batteries and charger – you’re getting a steal. If you already have a 24V Max battery, the price drops to well below $150. Holy guacamole. 

Final review: Kobalt 24V MAX string trimmer

I was pleasantly surprised by the Kobalt 24V Max attachment capable string trimmer. Sadly, I judged this string trimmer by its low price. But when I fired the string trimmer up and got to work, I ate my words. 

This string trimmer gets the stamp of approval from TLR.

SKIL 40V PWRCORE Power Head System Review: 2024

SKIL’s 40V PWRCORE Power Head System is brand new to the market. SKIL has been around for quite some time, but is just now getting into the Power Head System game.

Nice power comes from the top.

We’ve had the chance to review a few weed eaters with attachments that are all a part of a power head system, and SKIL has just made our list.

Today, we will deep dive into a bunch of features that make the SKIL PWRCORE 40 pretty nice. We also have a corresponding Youtube video that shows it in action.

Bottom line: The SKIL PWRCORE 40 multi-head system is a shockingly good system if you have SKIL tools and can save money on the batteries. You can grab this one at Lowe’s or on Amazon for a great price.

Jump ahead:

SKIL PWRCORE 40V Attachment Capable Power Head: Features

The SKIL PWRCORE 40V power head system that we got came with both weed eater and edger attachments, although more are likely to come soon. I expect a pole saw, cultivator, and snow blower attachment at least to be added in the next few months.

Overall really easy to use.

Let’s take a dive into our experience with the weed eater and edger attachments on the SKIL PWRCORE 40V system.

Using the SKIL PWR CORE 40 is easy

The SKIL Power Head comes with a nice molded rubber grip that feels super comfortable to use, almost like a pistol grip. One thing that I immediately noticed and liked was the safety feature. While I wouldn’t normally want a safety feature on my Power Head, it has the ability to move left and right to accommodate the primary hand of any user. 

The D-loop handle is pretty common on most premium power head systems, but I like that this one is slightly more adjustable to accommodate differences in height and hand position. 

Moves left and right.

Connecting the attachments into the power head is a breeze. You simply pop it into the head (there’s an arrow that shows you how to use it), then tighten it. Assembling the power head with each attachment was super simple as well.

SKIL PWR CORE has some serious power

The SKIL PWR CORE also comes with a variable speed trigger that lets you have complete control over the speed of the motor. On top of that variable speed trigger, there is a power switch that lets you move between levels 1 and 2 to have even further control over the speed and power of this unit.

One huge callout for this weed eater attachment is that it has a 16 inch cutting swath, which is comparable to some commercial weed eaters and definitely puts it in the higher range of residential weed eaters.

One thing that struck me immediately was how small the weed eater string was that came with this tool. It honestly looked like dental floss. We replaced it immediately, but found that .095” (the best size) string didn’t fit – so we had to settle for .080” string.

Big cutting swath!

Once the string was replaced, this thing had some decent power. The weed eater performed nicely, but so did the edger attachment. Fortunately, the edger attachment is a universal one and can fit any power head system. At a 9” radius, this edger attachment is pretty heavy-duty. 

The edger attachment can easily get down to 3 inches underground to help trench up the borders of your yard. It is easy to change the height on for anyone looking for a more shallow edging.

PWR Jump battery feature on the SKIL PWR CORE

One thing I like about this SKIL PWRCORE Power Head System is that it comes with a Power Jump charger. It supercharges your battery for the first 15 minutes of the charge, meaning it does 30% battery capacity upfront. And when you connect it, you’ll notice that it goes into overdrive and even makes noise trying to get the battery some instant juice.

This thing actually sweet.

The overall runtime claim is about 50 minutes on a fully charged battery. We put that to the test. Our classic zip-tie system on the trigger and safety (it was hard to do) held them down so that we could see how this thing does on full blast of the lower power setting 1. The SKIL PWRCORE 40 lasted for about 28 minutes before giving out.

After fully charging it again, we set it up on level 2 and ran it at full blast, where it lasted for about 23 minutes. Not bad, as we anticipated much more battery drain on the level two power setting.

Not bad!

Once the battery was totally dead, we timed how long it took to fully recharge – took about an hour and a half despite the advertised hour. 

The SKIL PWR CORE 40 is inexpensive

The PWRCORE Power Head System from SKIL comes in at right around $200 and comes with the weed eater head. Fortunately, it comes with a two year battery warranty and five year tool warranty.

One thing I like about this power head and describe it as a “high value” tool is that it comes with a brushless motor. This is how SKIL is able to put such a good warranty on this system.

Final Review: SKIL PWRCORE 40 Power Head System

This new power head system from SKIL has a lot to like. The brushless motor, large cutting swath, and universal attachment system at a relatively low cost make it a high value tool.

But they also made some claims about run time and battery charge time that were just plain false. And while this power head system has the capability of becoming really powerful, the fact that we couldn’t fit a higher, more appropriate-sized weed eater string made us feel like it couldn’t reach its full potential.

This is a MUST BUY if you already own the SKIL 40V battery and/or have a bunch of universal attachments as you can save a lot of money.

EGO’s is a bit nicer.

But if you are in the market for a new power head system and want to start from scratch, I’d research another like this EGO Multi-Head Power System.

What to look for in a battery-powered attachment system

If I would have read this article a few years ago, I would have made a different decision and likely saved hundreds of dollars. But I learned the hard way and want to make sure you don’t have to.

Here are the things I look for in a battery-powered attachment system:

A brushless motor

The first time around, I bought a brushed motor and I deeply regretted it a few months later. The main difference between brushed and brushless motors is how electricity is transferred from the battery to the motor. Brushed motors have a process that relies on friction. I quickly realized this when the palm of my hand was getting extremely hot while using the attachment system.

Brushless motors run cooler, more efficiently, provide more torque, and last longer. They are quickly becoming the gold standard in battery-powered lawn tools – but not everyone has caught up.

Universal attachments

Some of these weed eater attachment systems have the ability to take on any attachments. That’s a benefit to those of us that are looking to save money or have an existing attachment system that’s broken but the attachments work just fine. You can find attachments on Facebook marketplace or other second-hand stores for a way cheaper price. 

A high performing weed eater

Don’t just buy a weed eater with attachments because it is attachment capable. Buy a battery-powered weed eater that freaking dominates and also has the ability to add attachments. 

Good attachments

If I don’t mention this, I will get an email from one of you saying “you didn’t say to buy one with good attachments” so here you go. Obviously you want an attachment system that can accommodate high performing attachments that you will actually use. Avoid bundles that give you attachments that aren’t as good as the individual tools. The goal is to replace your other tools, not supplement them with an additional cost.

Why we review lawn tools

The reason we started this website in the first place was because we had so much trouble trying to find reasonable, understandable, honest reviews for lawn equipment. And it’s not cheap! After hours and hours of research, trying products and returning them, and messing up our yards – we started this site. 

We take tool testing seriously.

As guys who had to learn the hard way, we want you to know exactly what you are signing up for before you purchase a piece of equipment. That’s why we are committed to providing honest, easy-to-understand reviews that mean something.
