PowerSmart Weed Eaters: Gas or 40V Cordless?

PowerSmart makes value-focused outdoor power equipment, including gas and battery string trimmers aimed at homeowners who want to keep a yard, cabin lot or rural property under control without buying a professional-grade tool. Its gas trimmers pair a string head with a metal brush blade, which is useful on properties where grass gives way to thick weeds and saplings.
The four options here include two near-identical 25.4cc gas trimmers with brush cutter blades, a 40V cordless trimmer and edger sold as a bare tool, and a combo that pairs the gas trimmer with a 21-inch push mower, so the choice mostly comes down to gas reach and power versus cordless weight and convenience.

Cons

- Needs mixed gas and oil
The PowerSmart 25.4cc Gas Weed Wacker, model PS4532 in red, is a straight-shaft gas trimmer with a 25.4cc 2-cycle engine. It combines a 16-inch cutting width using 0.095-inch trimmer line with a 10-inch brush blade for thicker growth and small branches, so one tool can handle both lawn edges and overgrown fence lines.
PowerSmart describes a low-emission engine, a balanced design with shoulder straps for smoother, less tiring cuts, and a pull starter it says starts within five pulls. The shaft is designed to come apart for compact storage, which helps if the trimmer lives in a shed, truck bed or cabin closet. The listing gives a length of 73 inches and a weight of 18.8 pounds, which seems high for a trimmer of this size and may include packaging, so confirm before you plan on carrying it for long stretches. The listing also shows an odd pack size of 26 in one field; expect one trimmer.
As with any 2-cycle engine, it runs on a gasoline and oil mix, which means carrying a fuel can and mixing oil in the right ratio. This powersmart gas string trimmer suits cabin owners and rural homeowners with long grass, thick weeds and saplings where battery runtime would run short. For the lightest carry, the 40V model below is the alternative.

Pros
- Same 25.4cc engine
- Brush blade and 0.095-inch line
- Shoulder strap included
Cons
- 7 lbs listed weight
- Essentially same as red model
The PowerSmart Gas Weed Wacker 2-Cycle 25cc, model PS4532A-DP1 in black, shares its feature list with the red model word for word: a 25.4cc 2-cycle engine, a 10-inch brush blade, 0.095-inch trimmer line, a 16-inch cutting width, a low-emission design, shoulder straps, a quick pull start and easy disassembly for storage.
The listed weight is 18.7 pounds and the length is 73 inches, virtually identical to the red model. The model number differs slightly, but the listing does not describe any functional difference beyond color, so treat it as the same powersmart 25cc trimmer in a different finish.
Choose between the two gas trimmers based on availability and color preference. Both suit anyone who needs a powersmart brush cutter for occasional clearing on a larger property. If you are comparing dedicated gas clearing tools, our guide to a gas brush cutter covers heavier-duty options for thick undergrowth.

PowerSmart 40V 13″ Cordless String Trimmer for Campsites and Small Lots

- CONVENIENT FEATURES Auto-feed spool system with 0.065-inch line advancement, plus ergonomic design for comfortable operation and precise working
- COMPLETE PACKAGE Includes trimmer unit, auxiliary handle, safety guard, edge guide, and 3 replacement spools for immediate use
Pros
- Light at 6.1 lbs
- Trimmer-to-edger in one push
- Two speed settings
- Three spare spools included
Cons
- Battery and charger not included
- No brush blade
The PowerSmart 40V 13″ Cordless String Trimmer, model MB2462, is the lightweight option at 6.1 pounds, about a third of the listed weight of the gas trimmers. It converts from string trimmer to edger with a push button, and an L-shaped blade rotates 180 degrees to adjust the cutting width between 12 and 13 inches.
Two speed settings let you run higher speed for tough grass or lower speed to stretch runtime, with a listed top speed of 5000 rpm. An auto-feed spool advances 0.065-inch line, and the package includes an auxiliary handle, safety guard, edge guide and three replacement spools. It is sold as a bare tool, so the battery and charger are not included. The listing says a 40V MAX 4.0Ah battery delivers up to 60 minutes, but you must buy that battery separately to get that figure.
The powersmart 40v string trimmer suits cabin owners, RVers with a seasonal site and small-lot homeowners who value low weight, no fuel mixing and quiet operation. It lacks a brush blade and uses thinner line, so it will struggle with saplings and thick weeds. If you plan to recharge at an off-grid site, a solar generator for RV use can keep batteries topped up between sessions.

Pros
- 21-inch mower plus trimmer
- Mulch, bag or side discharge
- Auto choke on mower
Cons
- 62 lbs combined
- Ships in two boxes
The PowerSmart 21-Inch 144cc Push Gas Lawn mower and trimmer combo pairs a 21-inch high-wheel push mower with the 16-inch, 25.4cc gas string trimmer and 10-inch brush blade. The mower has a 144cc 4-cycle engine with recoil start and auto choke, and it can mulch, bag or side-discharge clippings.
The trimmer in this kit is the same PS4532 model, with 0.095-inch line, a 2-cycle engine and a pull start. Combined weight is 62 pounds, and the kit ships in two boxes that may arrive separately. PowerSmart pitches it for medium-sized yards.
This combo suits someone setting up a cabin or new property from scratch who needs both a mower and trimmer. Note that the mower runs on straight gas as a 4-cycle engine while the trimmer needs a gas and oil mix, so you will keep two fuel types on hand. For travelers who only need to tidy a campsite, it is far more than necessary.
Before you choose
How to Choose the Right PowerSmart Weed Eater
Start with the growth you need to cut. Tall grass, thick weeds and small saplings favor the gas trimmers with a 10-inch brush blade and heavier 0.095-inch line. Lawn edges and light weeds are well within reach of the 40V cordless model.
Next, consider weight and carry distance. The 40V trimmer weighs 6.1 pounds, while the gas trimmers list around 18.7 to 18.8 pounds. If you walk long fence lines or clear a campsite far from the vehicle, lighter is easier.
Fuel versus batteries is the next question. Gas gives unlimited runtime as long as you carry fuel, but requires mixing oil and more maintenance. The 40V tool is quieter and simpler but needs a separately purchased battery and a way to charge it. Readers comparing cordless options across brands can see our guide to a battery-powered weed eater.
Finally, storage. Both gas trimmers break down for compact storage, and the cordless model is shorter at 62 inches. When deciding which powersmart weed eater to buy, match the tool to your toughest growth and how far you will carry it.
Questions people ask
FAQ
Does the PowerSmart 40V trimmer include a battery?
No. It is sold as a bare tool without battery or charger. The listing’s 60-minute runtime refers to a 40V MAX 4.0Ah battery.
What is the difference between the two PowerSmart gas trimmers?
The listings describe the same 25.4cc engine, 16-inch cutting width, 10-inch brush blade and features. The main visible difference is color, red or black.
What trimmer line do PowerSmart weed eaters use?
The gas trimmers use 0.095-inch line. The 40V cordless trimmer uses 0.065-inch line on an auto-feed spool.
Can the PowerSmart gas weed wacker cut brush?
Yes. Both gas trimmers include a 10-inch brush blade for branches and thick growth.
Can the 40V PowerSmart trimmer edge?
Yes. It converts to an edger with a push button, and the blade rotates 180 degrees.
Which PowerSmart weed eater is best for a cabin or campsite?
For light trimming around a cabin, deck or campsite, the 40V cordless trimmer is the easiest to carry and store, and it avoids keeping mixed fuel on hand. For a lot that has gone wild with tall weeds and saplings, one of the 25.4cc gas trimmers with the brush blade will clear it faster and without worrying about battery runtime.
Is the PowerSmart combo worth it if I only need a trimmer?
No. The combo adds a 21-inch mower and brings total weight to 62 pounds. If you only need to trim, buy one of the standalone gas trimmers or the 40V model instead.
