What Customers Are Saying

Customers overwhelmingly praise this cordless string trimmer for its powerful brushless motor, lightweight design, and dual-speed control that rivals gas-powered models. Most highlight exceptional performance on thick weeds, fence lines, and brush up to an inch thick, with many noting it outperforms previous gas trimmers. The lightweight frame reduces fatigue, while the snap-in head and bump-feed spool with 0.095" line enhance ease of use. Customers appreciate battery compatibility with existing systems and report sufficient charge after completing full yards.

Powerful, Practical and Too Notch WeedWacker

Would Recommend

Used my new Kobalt WeedWacker today and it got the job done in almost half the time as my old unit. This device has input for 2 batteries for extra long run time. I was concerned it would be too heavy with the batteries but the design balances the weight distribution and it felt comfortable to use on a 1/4 acre yard. The batteries charged extremely fast with the included charger and 65 watt USB c cables. The unit is adjustable for any individual height requirements. It was easy to set up with ou...

Kobalt String Trimmer Kit 48v

Would Recommend

This is great and does a fantastic job quote quickly. I am unsure how long a full charge of a battery pack lasts, but the good news is that there's two battery packs (including accessories for charging)! Also, BIG NEWS, there are more attachments available. This seemingly singular KOBALT tool can be transformed into several others due to its UNIVERSAL CONNECT (UC) compatibility. I am already excited about getting the UC pole saw with extender; several possibilities for usefulness.

Great trimmer for home owner

Would Recommend

Packaged well and easy to unpack, assemble with clear instructions. Comes with more than what is minimally required which is a great plus. Weight is very light compared to most other trimmers and the power is on par with expectations, In thicker grass such as thick crab grass you do need to go slower than a gas powered however that is to be expected. Overall this is a great trimmer for normal yards and battery life is ample enough to finish an entire yard with left over power. Operating the tr...

Impressed is an understatement as I love this!!

Would Recommend

Absolutely 💯 percent impressed with this Kobalt electric weedeater. I have a Stihl one as comparison and this one I prefer as it is lighter and WHISPER QUIET! no need for hearing protection so you can hear things around you like vehicles, kids, or dogs. I live on a busy street so I want to be safe when they pass by. I used on a fenced in quarter acre and there was plenty of battery 🔋 life remaining to do more. I'm now going to be looking for other attachments I can use as this is now one ...

Excellent Replacement

Would Recommend

After many years of faithful service it was time to retire my 40 volt Kobalt trimmer and replace it with this newer 48 volt version. After opening the package and making sure all parts were included, the assembly was very quick and simple. The 24 volt batteries will charge on a standard Kobalt 24 volt charger or can be charged with the included adapter and charged with a UBC-C cable (also included). The 24 volt batteries are compatible with other Kobalt 24 volt tools. The overall weight of the 4...

Impressive Cordless Weed Trimmer!

Would Recommend

This unit is all you need for a normal sized yard. Pros: Very good battery life with two 24 VDC batteries for up to 48 VDC strength. Trimmed over 500 ft of driveway/sidewalk/curb edge, 400 ft of both sides of a field fence as well as around barn and several flat areas inaccessible with zero turn as well as perimeter of a 44x60 ft. building on a single charge. The 0.095 trimmer line is heavy duty enough for any grass trimming without excessive breakage and bump spooled easily. With the two b...

Powerful! But a strange battery charging system

Would Recommend

WOW has this thing got the power. You can FEEL it, and the bump feed works quite well. My only complaint is the weird charging method for the batteries. You have to have BOTH batteries attached and while it LOOKS like you can charge them ON the trimmer, it seems that only 1 will charge that way. There are USB-C ports for charging on the batteries and a seperate charging dock...a bit confusing but I plan to get to the bottom of how to do it the right way

Strong Performance Held Back by bad Features

Would Not Recommend

I wanted to like this Kobalt trimmer more than I do, but there are a couple of design choices that really hold it back. The biggest issue for me is the battery setup. It requires both batteries to run at the same time, but only comes with one charger. That’s honestly a pretty big inconvenience—charging becomes a slow, two-step process, and it just feels poorly thought out. That said, I will give credit where it’s due: the power surprised me. It’s stronger than I expected and honestly rivals my...

Works as advertised

Would Recommend

This is my 1st battery operated weed wacker and I have found no problem. The tool was easy to put together out of the box. No issues with the batteries. Compared to a gas powered unit the electric one was comparable to but much quieter which i really appreciated. I recommend it.

Solid trimmer for regular yard work.

Would Recommend

Before & after using the Kobalt 48V trimmer. My yard doesn’t have a ton of grass, but the areas that do were pretty overgrown. It handled it and got the job done. Not the most powerful I’ve used, but solid for regular yard work. Battery drains faster on thicker grass and charging takes a while, but overall it works. #TestedByJay #LawnCare #BeforeAndAfter #ProductReview #NoFluff

Weed eater

Would Recommend

Well cant have enough yard tools! I seem to eat weed trimmers. This one-is pretty tough and easy to put together. It can have other attachments, which is real convenient. Also can use the batteries across many platforms. Cool charger not bulky.

Lightweight and fast charging

Would Recommend

I’m impressed with the way the trimmer works. Not very heavy while working with and pretty quiet. Has two power settings and uses both batteries to activate. I like how you can change speed but remember, when doing this it exhausts your batteries faster. Besides that I think and know that this is a solid weed eater that could get a hours use if done correctly.

This is a must have if you run Kobalt power tools

I absolutely love the power and battery life. The fact that I'm considering selling my echo gas weed eater says something. And I haven't even purchased the edger or saw attachment.
