EGO Power+ ST1623T 16-Inch Line IQ 56V vs Husqvarna 525L 25.4cc Gas String Trimmer

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

EGO Power+ ST1623T 16-Inch Line IQ 56V comes out ahead by a narrow margin (4.7 vs 4.5). The gap is mostly about Suburban homeowners with 1/4 to 1 acre who want gas-class power, hate refueling, and don't mind a heavier tool for the convenience of auto line feed. — read the strengths below before deciding.

EGO Power+ ST1623T 16-Inch Line IQ 56V

4.7

$329

The EGO Power+ ST1623T pairs a brushless 56V motor with auto-feeding Line IQ and the brand's POWERLOAD spool, so most owners go a full season without ever touching the head. Pro Tool Reviews ran it for over an hour on a single 4.0Ah pack and scored it 9.7/10. The trade-offs are a 12.6 lb working weight and a price north of $300, but for a homeowner who wants gas-class performance without the maintenance, no other cordless trimmer sweats this combination of cutting width, ergonomics, and warranty.

Strengths

— 16-inch swath with Line IQ auto-feed eliminates the bump-feed dance
— POWERLOAD spool reload takes under 30 seconds with the included pre-cut line
— Telescopic carbon-fiber shaft carries a lifetime warranty

Watch-outs

— 12.6 lb working weight is on the heavy end of cordless picks
— Line IQ can shed string faster than it feeds when trimming hard fence lines
— Recharge time stretches to roughly 70 minutes on the standard 320W charger

Ranked #2 in Best String Trimmers

Husqvarna 525L 25.4cc Gas String Trimmer

4.5

$320

The Husqvarna 525L is the lightest 25cc pro-grade gas trimmer most homeowners will encounter at 9.7 lb dry, with the brand's X-Torq engine delivering 1.21 hp to an 18.1-inch cutting swath. Pro Tool Reviews scored the closely related 525LS at 8.8/10 and ranked the 525LST third overall in their gas trimmer shootout at 89 points. The recoil is the soft spot and you're still pumping mixed gas, but for landscapers and homeowners running multi-acre lots in heavy growth, this is the trimmer that earns its keep all day.

Strengths

— Pro-grade 25.4cc X-Torq engine produces 1.21 hp at 6,500 rpm
— 9.7 lb dry weight is exceptionally light for a 25cc straight-shaft
— Tap'n Go bump head reloads quickly and accepts standard 0.095-inch line

Watch-outs

— Pull-start recoil is the part most commonly cited as a weak point
— Two-stroke fuel mixing required and emissions/noise rule it out for some neighborhoods
— Two-year limited warranty trails some battery competitors on coverage

How they stack up

EGO Power+ ST1623T 16-Inch Line IQ 56V

Outclasses the Worx WG170 GT Revolution on cutting width (16 in vs 12 in), runtime, and build, but you pay nearly triple. Sits below the Husqvarna 525L on raw cutting torque in heavy weeds but matches it on noise, fumes, and warm-up time.

Husqvarna 525L 25.4cc Gas String Trimmer

Outcuts every battery option in this list — including the EGO ST1623T and Ryobi RY402110 — in tall heavy weeds thanks to the X-Torq powerband. The trade is the only gas pick here: fuel mixing and pull starts the cordless picks don't ask of you. About 3 lb lighter than other 25cc+ pro gas trimmers in its class.
