Ego is a leader in battery powered OPE products. The new ST1521S utilizes a Carbon Fiber shaft making it strong and lightweight. The trimmer is powerful and the Powerload head design means no more fumbling around with loading line.
As you know I am a huge fan of EGO OPE (Outdoor Power Equipment) tools. I was once that guy who never would have given up gas tools until I tried Ego. Now I am sold on battery-powered OPE products. I am not saying battery powered is as strong as gas, but it does the job and has plenty of power for your average homeowner. I have a typical house in a typical town where the houses are closer together. There is still plenty of room for my kids to play soccer and other outdoor actives so my yard isn’t extremely small, but it’s not an acre. So for the people like me or with a little larger lots, I think battery power is the way to go. So let’s jump into the EGO String Trimmer Review.
Ego String Trimmer Review Overview
Here is the perfect example why I love cordless OPE tools. I live in the Chicago area and spring is finally here. Normally when I fire up my lawn mower, trimmer or hedger, I am messing around. I have to get new gas for the year, fill everything up and then pull the starter cord until my arm falls off. If you have gas products, you know what I mean, it’s a pain. All you want to do is cut your grass and then get on with your day, but you can’t because you’re messing around with everything else expect cutting grass.
This year, I grabbed my EGO battery, which was charged because I use the snow blower. I put the battery on the mower and just started cutting. How can you argue with this type of productivity?
OK, I know you’re here for the EGO String Trimmer review but I wanted to at least touch base on battery OPE because I know there are still a ton of people who aren’t sold on this technology and ability to go all cordless and still be able to complete the job. I am not here to sell you on this technology, just to let you know my experience. Again I am not comparing this to a gas string trimmer.
EGO has had a string trimmer out for a while. The new ST1521S has a couple cool options on it so let’s see if it’s worth buying or even upgrading.
Ego String Trimmer Review Features
EGO designed the ST1521S with the battery on the back of the trimmer, which is also where the motor is located. You can buy this as a bare tool or with a 2.5 Ah battery. Since I have the EGO Mower and Snowblower, I also have a 7.5 Ah battery and a 5 Ah battery. I found the trimmer has a good balance with the 2.5 Ah battery and has plenty of run time to get my yard done. When I use a 5Ah battery, it becomes a little bit unbalanced and heavy in the back end of the trimmer. EGO uses a brushless motor to power the trimmer.
The string trimmer runs off a 56V battery which is universal for all EGO’s OPE products.
One new feature to this string trimmer is the Carbon Fiber shaft. Not only does this material make the trimmer lighter, but also it’s extremely strong.
All tools need some type of safety feature. Some safety features we have seen over the years have made the tool a pain to operate. With the EGO, it has a nice setup. You can easily depress the safety switch with your thumb and then pull the trigger with your finger, which is variable speed.
The grip has a nice rubber overmold and is comfortable.
The trimmer features two lines which mean more cutting in less time. It features a 15” cutting swath. The trimmer is designed to be used with .095” line.
On the bottom of the head, you can advance line using a bump feature. While the trimmer is running, you hit the head on the ground and it will advance line.
This is the coolest feature of this trimmer, the Powerload head. If you have ever had to replace the line in a trimmer, you know what a pain in the butt it can be. I won’t even go into all the issues I have when replacing the line.
With the EGO Powerload, you don’t even have to remove the head. Just put the line through the head. Once you’re about halfway through, push the button close to the head and it will wind it up for you. Seriously, how cool is this? It’s one of those features that should have been designed decades ago. Trust me, it would have saved me a ton of money because I wouldn’t have had to pay all that money to the swear jar.
The handle has a soft rubber grip and you can also change where it sits on the shaft. You will need an Allen wrench to move it.
Ego String Trimmer Review Performance
So how does this perform? For a battery powered string trimmer, it’s one of the strongest string trimmers we have tested. Again we are not comparing this to gas. So when it comes to your everyday trimmer needs, this tool jams. If your cutting through thick forests, then gas is the way to go. Now don’t get me wrong, this does a great job in heavy and tall grass and weeds, but if your clearing a lot of land, then I would go with gas.
I also noticed this trimmer doesn’t have a ton of feedback. We have tried trimmers where your hands are numb because of the vibrations but with the EGO, we found it smooth.
Another noticeable performance report was the bump and feed string. Again with some of the trimmers, we have tested, you have to really hit the head hard and repeatedly to advance the line. With this trimmer, it was a quick bump and the line advanced. It was nice not having to fight the line.
One of the downsides to this trimmer, which we see on all trimmers is the length of the shaft. I am 6′ tall and wish the trimmer was a little longer. After a longer period of use, I do feel it on my back. If it was another 7-10″ longer, it would make the world of difference. However then for the people who are 5″, it would be too long for them.
Ego String Trimmer Review Value
If you need to buy the kit, which includes a 2.5 Ah battery and charger, you will pay about $230 at The Home Depot. If you already have a battery, you can get the bare tool for about $170. When it comes to battery string trimmers, this is definitely on the higher end of the price line. However, I also believe the quality and power is the highest in the battery string trimmer market.
Ego String Trimmer Review Final Thought
All in all, I am a huge fan of this string trimmer. While I like the carbon fiber shaft for weight and strength, I love the Powerline head and how easy it is to replace the line. With a five year warranty and a lifetime warranty on the shaft, how can you go wrong? The best part of this string trimmer is that it’s in a family of other great OPE tools that run off the same 56V battery.
