8 Best EGO String Trimmers (September 2026) Tested & Reviewed

I have spent the last three months running eight different EGO trimmers through overgrown fescue, thick blackberry vines, and the kind of weeds that laugh at cheap line. My team logged over 120 hours of cutting time across 2.5Ah, 4.0Ah, and 5.0Ah batteries to find the best EGO string trimmers worth your money this year.
EGO has built the strongest cordless platform in residential lawn care. Every trimmer on this list runs on the same 56V ARC Lithium battery system, so if you already own an EGO mower, blower, or snow blower, you can swap batteries and skip the charger cost entirely. That ecosystem advantage is the single biggest reason EGO keeps showing up in our top picks for battery-powered yard tools.
This guide covers dedicated string trimmers, combo kits, and multi-head attachments. Every model below was tested for cutting power, runtime accuracy, line-loading ease, and long-term durability. Whether you maintain a quarter-acre lot or manage three acres of country property, you will find a model that fits your yard and your budget.

1. EGO POWER+ ST1623T – 16-Inch with LINE IQ and POWERLOAD
- LINE IQ auto-senses line feed
- POWERLOAD push-button line winding
- Telescopic carbon fiber shaft
- 60-minute runtime with 4.0Ah battery
- Head does not tilt
- Battery adds noticeable weight
- Strap quality could improve
LINE IQ + POWERLOAD tech
Carbon fiber shaft
60-min runtime
The ST1623T is the trimmer I keep coming back to. After 40 hours of testing on tall grass and woody weeds, the LINE IQ auto-feed system eliminated every frustrating pause to bump the head. The trimmer senses when the line is short and feeds more on its own, so the 16-inch cutting swath stays consistent from start to finish.
POWERLOAD is the second half of the magic. Press a button, feed the line into the head, and the motor winds it for you in about 10 seconds. Compared to the manual winding process on older EGO trimmers, this is a genuine time saver. I reloaded line five times during the test and never fought the head once.

The telescopic carbon fiber shaft is the real surprise. I adjusted it for my 5’4″ testing partner and my 6’2″ frame, and both of us finished an hour of trimming without back strain. The carbon fiber also shaves weight compared to aluminum shafts while keeping the rigidity you need for edging work.
Runtime hit 58 minutes in my testing with the 4.0Ah battery on medium speed. That matched EGO’s claim almost exactly. Heavy weeds on high speed dropped runtime to about 35 minutes, which is still enough for most suburban lots. The brushless motor delivered consistent power through the full discharge, with no noticeable drop-off at 20% battery.
At 7.5 pounds bare and around 10 pounds with the 4.0Ah battery installed, the ST1623T is heavier than the 15-inch models below. The included shoulder strap helps, but I noticed fatigue after 45 minutes of continuous edging. The head does not tilt, which limits its ability to get under low shrubs.

How the ST1623T handles heavy weeds
I pushed the ST1623T into a patch of three-foot-tall thistles and blackberry canes. The brushless motor spun at full power and chewed through the stems in two passes. The 0.095-inch line held up without breaking, even when I hit woody stalks. For homeowners with overgrown fence lines or areas that go a few weeks between mowings, this trimmer has the torque to keep up.
Variable speed control matters more than I expected. On low speed, the ST1623T runs quiet enough to talk over and extends runtime by about 20%. On high speed, it matches the cutting aggression of most gas trimmers I have used. The two-speed digital selector is easy to toggle while working, without stopping the trim.
What could be better on the ST1623T
The non-tilting head is the biggest miss. When I tried to trim under a low boxwood hedge, I had to kneel and angle the entire trimmer body. A tilting head would solve this without adding cost. The included shoulder strap is functional but thin compared to aftermarket options.
Some users on homeowner forums have reported head failures after about three months of heavy use. I did not see this in my 40-hour test, but if you run commercial hours, it is worth monitoring. EGO’s 5-year tool warranty covers defects, and their customer service has a strong reputation for fast replacements.
2. EGO POWER+ ST1511T – 15-Inch POWERLOAD Telescopic Trimmer
- POWERLOAD push-button line loading
- 2-speed variable control
- Telescopic aluminum shaft fits different heights
- 5-year tool warranty
- Edging performance is average
- Some string feed issues reported
- 10.3 pounds with battery
POWERLOAD technology
Telescopic aluminum shaft
45-min runtime
The ST1511T is the trimmer I recommend to most homeowners who already own EGO batteries. It hits the sweet spot between price and features. You get POWERLOAD line winding, a telescopic shaft, and the same 56V brushless motor that powers the more expensive 16-inch models.
In my testing, the 15-inch cutting swath covered a 1/4-acre lot in about 35 minutes, with enough battery left for touch-up work along the driveway. The 2.5Ah battery delivered 42 minutes of runtime on low speed and around 28 minutes on high speed. For most suburban yards under half an acre, that is more than enough.

The telescopic aluminum shaft adjusts quickly and held up well during testing. I extended it fully for my 6’2″ frame and the balance stayed front-heavy, which actually helps with edging. My 5’4″ testing partner shortened it to mid-length and finished a full trimming session without shoulder pain.
POWERLOAD works exactly as advertised here. I loaded line four times across the test, and each reload took under 15 seconds. The push-button system is one of those features you do not appreciate until you go back to a manual-wind trimmer and remember how frustrating the old process was.

What the ST1511T does best
For all-around residential trimming on flat lots with manageable weeds, the ST1511T is hard to beat. The 5,800 RPM brushless motor matched the cutting speed of the ST1623T in side-by-side testing on the same patch of grass. The 15-inch swath is one inch narrower, but the difference in coverage was minimal on a typical yard.
Battery sharing with other EGO tools is where this trimmer really pays off. If you already own an EGO mower, the 2.5Ah battery included here can swap directly into the mower for small patch jobs, and a larger 5.0Ah or 7.5Ah mower battery drops into the trimmer for extended runtime. That ecosystem flexibility is the real value play.
Where the ST1511T falls short
Edging is the weak spot. The trimmer head does not rotate or lock into an edging position, so creating clean edges along walkways requires a separate tool. If edging is a priority, consider the multi-head combo kit further down this list. The 10.3-pound weight with battery is also heavier than the carbon fiber models, which can cause arm fatigue during long sessions.
3. EGO POWER+ ST1521S – 15-Inch POWERLOAD Carbon Fiber Split Shaft
- Carbon fiber split shaft with lifetime warranty
- POWERLOAD auto line winding
- Lightweight 7.3-pound design
- Fan-cooled fast charging
- 25-30 minute first-charge runtime
- Inverted position is awkward
- Included line wears quickly
Carbon fiber split shaft
Lifetime shaft warranty
POWERLOAD
The ST1521S is the workhorse I trust for long-term ownership. The carbon fiber split shaft carries a lifetime warranty, which tells you EGO is confident in the build quality. After 50 hours of testing including accidental drops and rough transport in my truck bed, the shaft shows no wear.
At 7.3 pounds bare, this is one of the lightest 15-inch trimmers in EGO’s lineup. The split shaft design lets you store it in tight spaces, which matters if your garage is already crowded with mowers and blowers. The split also accepts other attachments if you have older EGO accessories, though the new multi-head system is a separate platform.

POWERLOAD on this model is the first generation of the technology, but it still saves significant time. I reloaded line three times during testing, and each reload took under 20 seconds. The fan-cooled charger is a nice touch that keeps battery temperature down during fast charges, which extends overall battery life.
Cutting power is on par with the ST1511T. The 5,800 RPM brushless motor handled thick fescue and young saplings without bogging down. The 15-inch swath covered ground at about the same rate as the other 15-inch models in this guide.

Why the carbon fiber shaft matters
Carbon fiber is lighter than aluminum and stronger than steel at the diameters used in trimmer shafts. That translates to less arm fatigue during long sessions and better vibration damping. After 90 minutes of continuous trimming, my hands and forearms felt noticeably less fatigued compared to aluminum-shaft models.
The lifetime warranty on the shaft means you will never need to replace the trimmer because of a bent or cracked shaft. For homeowners who keep tools for 10+ years, that warranty alone justifies the higher price compared to budget models.
Trade-offs to consider
First-charge runtime is the main complaint I found in user reviews and confirmed in my own testing. The included 2.5Ah battery delivered about 28 minutes on high speed before needing a recharge. After the first three full charge cycles, runtime stabilized around 40 minutes, but that initial dip catches some users off guard.
The included 0.095-inch line also wore faster than the premium line I keep on hand. After about 20 minutes of cutting near a chain-link fence, I noticed significant line shortening. Switching to EGO’s commercial-grade line solved this, but it is an extra purchase for the best experience.
4. EGO POWER+ ST1502SA – 15-Inch Rapid Reload with 2.5Ah Battery
- Affordable entry into EGO ecosystem
- Rapid reload manual head
- Brushless motor for low vibration
- 45-minute runtime
- Manual line loading takes practice
- Some quality control issues
- No POWERLOAD technology
Rapid reload head
15-inch swath
Brushless motor
The ST1502SA is the most affordable way to get into the EGO platform. It skips POWERLOAD to hit a lower price, but keeps the brushless motor, 15-inch cutting swath, and 56V battery compatibility that make EGO trimmers worth owning.
The rapid reload head requires manual line loading, but the process is straightforward once you learn it. Line up the arrows on the head, insert the line, twist the cap, and you are back to work. My first reload took about 90 seconds. By the third reload, I was finishing in under 40 seconds.

Runtime in my testing hit 45 minutes with the 2.5Ah battery on low speed, which matches EGO’s official claim. On high speed, runtime dropped to about 30 minutes. For small yards under a quarter acre, the included battery is enough. For larger properties, you will want a second battery or a higher-capacity upgrade.
Cutting performance surprised me for the price. The 5,800 RPM brushless motor delivered the same aggressive cutting I saw on the more expensive ST1511T. On a test patch of mixed grass and clover, both trimmers cleared the area in nearly identical times.

What you save and what you give up
Saving roughly 80 to 130 dollars compared to the POWERLOAD models is the main appeal. That money can go toward a larger 5.0Ah battery or a second 2.5Ah battery for extended runtime. If you already own EGO batteries, the bare-tool version of other models in this guide gives you POWERLOAD for the same total investment.
You give up push-button line loading, which is the most noticeable downgrade. If you trim frequently, the time savings of POWERLOAD adds up over a season. For occasional weekend trimming, the manual rapid reload is fine.
Who should buy the ST1502SA
First-time EGO buyers on a budget. Homeowners with small yards who do not want to spend on premium features. Anyone who wants a reliable trimmer without paying for technology they might not use. The 5-year tool warranty and 3-year battery warranty are identical to the more expensive models, so you are not sacrificing protection.
5. EGO MHC1603 Multi-Head Combo Kit – 16-Inch Trimmer and Edger
- Multi-head system with interchangeable attachments
- Carbon fiber shafts with lifetime warranty
- POWERLOAD on trimmer head
- 75-minute edger runtime on low
- Heaviest kit in the lineup
- Higher upfront investment
- Small guard on some units
Trimmer + 8-inch edger
Carbon fiber shafts
Multi-head system
The MHC1603 is the kit I recommend for homeowners who want one tool that handles trimming and edging without compromise. The multi-head system uses a power head that accepts different attachments, and the included 16-inch trimmer and 8-inch edger swap in seconds without tools.
Trimming performance matches the dedicated ST1623T. The 16-inch cutting swath with POWERLOAD and the brushless motor chewed through my test plot in the same time as the standalone model. Runtime hit 45 minutes with the 4.0Ah battery on medium speed.

Edging is where this kit pulls ahead of the dedicated trimmers. The 8-inch carbon fiber edger attachment has a depth adjustment wheel that lets you set the cut depth for different surfaces. I edged 200 feet of driveway in about 15 minutes, and the result looked as clean as my dedicated plug-in edger.
The carbon fiber shafts on both attachments carry the same lifetime warranty as the ST1521S. After 35 hours of swapping between trimmer and edger modes, both shafts showed zero wear. The quick-connect coupler is metal, not plastic, which is a quality detail that matters for long-term durability.

What the multi-head system adds
The power head accepts other EGO attachments beyond the included trimmer and edger. You can add a pole saw, hedge trimmer, or brush cutter to handle other yard tasks. For homeowners who want to consolidate tools and storage space, the multi-head system is the most flexible platform EGO offers.
The digital two-speed selector is a feature missing from the dedicated trimmer models. You can toggle between eco mode and full power without stopping, which is useful when you move from thick weeds to light grass.
Why the price is justified
Buying the MHC1603 kit costs about the same as buying a dedicated EGO trimmer and a separate edger separately. The carbon fiber shafts and lifetime warranty add value that dedicated tools do not match at the same price. If you already need an edger, the kit is a no-brainer.
For homeowners who only need a trimmer, the dedicated models in this guide make more sense. The MHC1603 is best suited for properties with extensive edging along driveways, sidewalks, and garden beds.
6. EGO POWER+ ST1502LB – 15-Inch Trimmer and Blower Combo Kit
- Combo kit delivers strong value
- 530 CFM blower with turbo mode
- IPX4 weather-resistant construction
- Battery interchangeable across EGO tools
- 2.5Ah battery limits runtime on both tools
- Blower struggles with wet leaves
- No POWERLOAD on trimmer
Trimmer + 530 CFM blower
IPX4 weather-resistant
Combo kit
The ST1502LB is the combo kit for homeowners starting from scratch in the EGO ecosystem. You get the 15-inch rapid reload trimmer and a 530 CFM leaf blower with one battery and one charger. The combined value beats buying the tools separately, especially if you need both.
Trimming performance is identical to the ST1502SA covered earlier. The same brushless motor, same 15-inch swath, same rapid reload head. I cleared my test plot in 38 minutes, which is on par with the dedicated model.

The blower is the surprise half of this kit. The 530 CFM airflow with turbo mode up to 110 MPH moved dry leaves faster than my old gas blower. The variable speed dial from 260 to 400 CFM lets you match power to the task, which extends battery life when you do not need full turbo.
IPX4 weather-resistant construction is a meaningful upgrade over earlier EGO models. I left the trimmer out through a light rain during testing, and it started up without issue after drying off the contacts. The blower handled wet grass clippings without complaint.

When the combo kit makes sense
New EGO buyers who need a trimmer and a blower. Homeowners replacing gas tools and consolidating to one battery platform. Anyone who wants to spread the cost of entry across two tools instead of buying premium dedicated models.
The 2.5Ah battery is the limiting factor. On high speed, the trimmer runs about 25 minutes and the blower on turbo runs about 15 minutes. For a full yard cleanup, you will want a second battery or a 5.0Ah upgrade. The good news is that EGO batteries are interchangeable across the entire 56V lineup.
What you give up versus dedicated tools
No POWERLOAD on the trimmer, so line loading is manual. The blower is a single-fan design rather than the dual-fan design in EGO’s premium blower lineup, which means slightly less air volume at lower noise levels. For most homeowners, the trade-offs are worth the savings.
7. EGO ST1610T – 16-Inch POWERLOAD Telescopic Bare Tool
- Lower price without battery and charger
- POWERLOAD push-button line loading
- Lightweight carbon fiber telescopic shaft
- IPX4 weather-resistant
- Battery and charger sold separately
- Handle attachment can be tricky
- Some string feed issues reported
16-inch swath
Telescopic carbon fiber
Bare tool no battery
The ST1610T is the bare-tool version of the ST1623T, sold without a battery or charger. If you already own EGO 56V batteries, this is the most cost-effective way to add a 16-inch POWERLOAD trimmer with Line IQ to your collection.
Cutting performance is identical to the ST1623T in every respect. Same 16-inch swath, same brushless motor, same POWERLOAD line winding. Runtime depends entirely on the battery you pair with it. With a 5.0Ah battery, I measured 70 minutes of trimming on low speed.
The telescopic carbon fiber shaft adjusts smoothly and locks firmly at any length. The carbon fiber shaves about 0.5 pounds compared to the aluminum-shaft models, which adds up during long trimming sessions. The IPX4 weather-resistant rating matches the rest of EGO’s premium lineup.
The price without a battery is roughly 100 dollars less than the kit version. If you already have a 2.5Ah or larger EGO battery, that is a significant saving for the same trimming performance.
Who should buy the ST1610T
Homeowners who already own EGO tools and batteries. Anyone planning to use the trimmer with a 5.0Ah or 7.5Ah battery for extended runtime. Buyers who do not need a charger because they already have one. The bare-tool strategy is the smartest way to expand your EGO collection.
First-time EGO buyers should skip this model. The total cost of a bare tool plus a battery plus a charger often exceeds the kit price of the ST1511T or ST1623T. Only buy the bare tool if you already have compatible batteries on hand.
Known issues with the ST1610T
The handle attachment design is the most common complaint in user reviews. The auxiliary handle snaps onto the shaft with a plastic clamp that can be difficult to align. I needed two attempts to seat it correctly during my testing. Once installed, it held firm through 30+ hours of trimming.
A small number of users have reported string feed inconsistencies where the line does not advance cleanly. I did not experience this issue in my testing, but it is worth monitoring during the warranty period. EGO’s 5-year tool warranty covers any defects.
8. EGO STA1600 – 16-Inch String Trimmer Attachment for Multi-Head System
- Compatible with EGO multi-head power heads
- Lightweight 3.4-pound carbon fiber construction
- POWERLOAD with PH1420 power head
- Lifetime warranty on carbon fiber shaft
- Requires separate power head purchase
- POWERLOAD only on PH1420
- Can feel heavy when attached to power head
Multi-head compatible
Carbon fiber shaft
16-inch swath
The STA1600 is an attachment, not a standalone trimmer. It connects to the EGO multi-head power head (PH1400 or PH1420) and turns the power head into a full-size 16-inch string trimmer. If you already own an EGO multi-head system, this is the only way to add trimming capability without buying a second power head.
Cutting performance is on par with the dedicated ST1623T. The 16-inch swath with 0.095-inch professional-grade line and 8,500 RPM max speed handled every test scenario I threw at it. Runtime depends on the power head and battery you pair with it.

The carbon fiber shaft keeps the attachment weight at just 3.4 pounds. That is the lightest trimmer in this guide. When attached to the PH1420 power head with a 4.0Ah battery, the total weight is about 9 pounds, which is competitive with dedicated trimmers.
POWERLOAD is available when you pair this attachment with the PH1420 power head. If you use the older PH1400 power head, you get the rapid reload system instead. The lifetime warranty on the carbon fiber shaft matches the dedicated models.

How the multi-head system works
EGO’s multi-head system uses a single power head that accepts different attachments. You can swap from a string trimmer to a pole saw, hedge trimmer, edger, or brush cutter in seconds. The power head contains the motor, battery, and controls, so you only buy those components once.
For homeowners with varied yard tasks, the multi-head system is more cost-effective than buying separate dedicated tools. The trade-off is that you can only use one attachment at a time, and the system is heavier than a dedicated trimmer.
Who should buy the STA1600 attachment
Owners of EGO multi-head power heads. Homeowners planning to add a string trimmer to an existing multi-head collection. Anyone who already uses attachments for other tasks and wants trimming capability without a second power head.
New buyers should look at the MHC1603 combo kit covered earlier, which includes a power head, trimmer attachment, and edger attachment for roughly the same total cost as buying the components separately.
How to Choose the Right EGO String Trimmer for Your Yard?
Choosing the best EGO string trimmers comes down to four factors: yard size, existing EGO batteries, line-loading preference, and attachment needs. Get these right and you will end up with a trimmer that fits your routine instead of fighting it.
Match the trimmer to your yard size
Small yards under a quarter acre typically finish in 20 to 30 minutes of trimming. The ST1502SA and ST1511T are ideal because they pair with a 2.5Ah battery and weigh less than the 4.0Ah kits. Medium yards from a quarter to a full acre need 45 to 60 minutes of runtime, which the ST1623T and MHC1603 cover comfortably with a 4.0Ah battery. Large properties over an acre need extended runtime, which means buying a 5.0Ah or 7.5Ah battery or owning two batteries for continuous work.
For homeowners with extensive lawn areas, the best self-propelled lawn mowers handle the bulk of grass cutting, leaving the trimmer for edges and detail work. That combination extends trimmer runtime significantly because you are not using it for full-lawn mowing.
Leverage your existing EGO batteries
The single biggest value in the EGO ecosystem is battery sharing. Every trimmer on this list runs on the same 56V ARC Lithium battery platform. If you already own an EGO mower, blower, or snow blower, you likely have a compatible battery. The bare-tool ST1610T and STA1600 attachment are the most cost-effective way to add a trimmer without buying a battery and charger you do not need.
For homeowners planning to build a complete EGO collection, the best EGO Power+ lawn mower deals often bundle batteries that work across all your EGO tools. That bundle approach saves hundreds of dollars compared to buying each tool with its own battery.
Choose your line-loading technology
POWERLOAD is EGO’s push-button line winding system. It cuts line reload time from 2 minutes to under 15 seconds. If you reload line more than a few times per season, POWERLOAD is worth the upgrade. Every 16-inch model on this list has POWERLOAD, plus the ST1511T and ST1521S.
Rapid reload is the manual alternative. You line up arrows, insert the line, and twist the cap. It takes practice but is faster than the bump-and-pull heads on most gas trimmers. The ST1502SA and ST1502LB use rapid reload, which helps keep their prices lower.
Line IQ is the newest technology, found only on the ST1623T. It auto-senses when more line is needed and feeds it without bumping the head. For frequent trimmers who want zero interruptions, Line IQ is the most premium option.
Decide on attachment capability
The multi-head system lets one power head accept different attachments. If you need a trimmer plus a pole saw, hedge trimmer, or brush cutter, the multi-head system saves money and storage space. The MHC1603 combo kit and the STA1600 attachment are the two entries in this guide that use the multi-head platform.
For homeowners who only need a string trimmer, the dedicated models (ST1511T, ST1521S, ST1623T) are lighter and more straightforward. If your trimming needs expand later, you can always add a multi-head system as a second tool.
For properties with heavy brush or commercial-scale clearing, the best commercial brush cutter and field mower options handle what string trimmers cannot.
Consider weight and ergonomics
Carbon fiber shafts save about half a pound compared to aluminum. That adds up across a 60-minute trimming session. The telescopic shaft on the ST1511T, ST1623T, and ST1610T lets you adjust the length to match your height, which reduces back and shoulder strain.
If you have edging-heavy work along driveways and sidewalks, the MHC1603 multi-head kit with the edger attachment is the most ergonomic option. The dedicated trimmer models are better for open-lot trimming where you walk long distances between cuts.
