Electric vs Battery Weed Eaters: Which Should You Buy?
As an Amazon Associate we earn from qualifying purchases.
Electric weed eater vs battery is mostly a question of power source and pack setup. Many listings call a trimmer “electric,” but the ones in this comparison are all battery powered, meaning a cordless trimmer that runs on a rechargeable pack rather than a cord. The real choice is between battery packs and their specs: the voltage, the amp-hour rating, the runtime the listing states, the weight, and whether the head is a string head or a blade head. Pick the battery you can run for the length of your yard, the weight you can hold for that long, and the head that matches the growth you cut. The eight listings below give those facts for each model.
Quick answer
- A battery weed eater with two packs gives the longest uninterrupted work, since you can swap one pack while the other charges. The Ohey, MoYohos and Windpost listings state two batteries.
- For light weight, the ALSO GO 24V model lists 2.8 pounds, and the Aokia bullets give 3.72 pounds for its single 12V pack.
- For thick weeds and brush, the blade-capable heads and steel or saw blades in the MoYohos, Ohey and Windpost listings are the group to compare.
- Check the battery brand before buying. The DeWalt-compatible and Milwaukee-compatible listings sell the tool without a battery.
Is it electric or battery? What the listings mean
The word “electric” in a listing usually means the trimmer has a motor and no gas engine. It does not mean a corded machine in this group. Every model in the pack is listed as battery powered, and none is listed as corded. So the comparison that matters here is between battery types: the voltage, the pack count, the runtime and the weight. If you need a corded electric trimmer, look for a listing that states a cord and an outlet, because none of the eight below does.
Two points are worth a closer look. First, the stated runtime depends on the pack. The DCA listing gives 60 minutes at low speed and 36 minutes at high speed on a 4.0Ah pack, and the ALSO GO 21V listing gives 40 minutes on two 2.5Ah packs. Second, several listings give a range or an alternate figure. The Ohey listing states 90 to 120 minutes using two 3000mAh packs alternately, and the FLYINGJOING listing states 120 to 180 minutes with two batteries. These are the listing claims, and they are not measured here.

The table shows what each listing says. Where a listing gives no runtime or no weight, the cell says “Not stated,” and no figure is filled in from memory. Some specs in these listings disagree with the bullets, for example the Aokia weight and the Windpost pack type, so read the full listing before ordering.
Product picks, one by one
MoYohos 21V cordless weed wacker
The MoYohos has an 880W motor rated up to 18,000 RPM and two 4000mAh packs with a charger. It comes with saw blades, rhombus alloy blades and plastic blades, and its shaft extends from 35 to 47 inches. The bullets say the head adjusts from 0 to 90 degrees, and the listing gives a weight of 3.9 pounds. This is a blade-capable trimmer that suits a reader who cuts both grass and heavier growth.
BLACK+DECKER 20V MAX weed eater, edger and sweeper combo (LCC222)
This is a combo kit. The listing includes two 20V MAX batteries and a charger, a string trimmer with automatic line feed, and a cordless leaf blower sold as a sweeper. The bullets say the trimmer weighs 4.5 pounds, the blower 3.7 pounds, and the battery holds its charge for up to 18 months. The listing gives a 10-inch cutting width. It is the choice for a reader who wants a trimmer and a blower on the same battery platform.
DCA 20V 14-inch brushless string trimmer
The DCA is a brushless trimmer with a 4000mAh pack and a charger. The listing gives 60 minutes on low speed and 36 minutes on high speed, a two-speed setting of 4600 and 6200 RPM, and a cutting width of 12 to 14 inches. The bump auto-feed head releases line with a tap. The listing says the trimmer weighs 7.6 pounds with the battery, and the shaft is aluminum alloy. It suits a reader who wants a longer runtime and a wider cut.
Windpost cordless 5-in-1 weed wacker
The Windpost comes with two rechargeable packs, a charger, auxiliary wheels, gloves and five blades. The listing states a 750W brushless motor at 18,000 RPM, a telescopic rod of 98 to 155 centimeters, and a dual safety switch. The specs list the pack as 21V 4000mAh in the bullets, and the specs table gives a different battery description, so check the listing. It is a good fit for a reader who wants a wheeled trimmer with several blade types.
ALSO GO 24V weed eater (HG0312)
This ALSO GO model comes with two 24V 2.0Ah packs. The bullets say the motor is a 650W pure copper motor at 11,000 RPM, and the shaft extends from 35 to 47 inches. The listing says the trimmer weighs three pounds and has five blade types, a dual safety lock, and an auxiliary wheel. The bullets describe it as lightweight for seniors and women. The runtime is not stated as a figure in the listing.
Ohey 21V 20000 RPM weed eater (ST-01)
The Ohey listing is the longest-runtime claim in this group. It states two 21V 3000mAh packs, a combined total of 6000mAh, and 90 to 120 minutes of runtime when the packs are used alternately. The head includes 5 long trimmer lines, 5 short lines, 4 steel blades and 2 brush cutter blades, with an edging wheel. The shaft is listed at 43 to 55 inches. The listing also gives an LED display for remaining power.
ALSO GO 21V 2.5Ah 2-in-1 trimmer (HG0556)
This ALSO GO comes with two 2.5Ah packs and a fast charger. The listing says it runs for 40 minutes and has an auto line feed system with 10 spare spools. The head rotates 90 degrees for edging and tilts from 0 to 90 degrees. The listing gives a 12-inch cutting width and a weight of 5.3 pounds. It suits a reader who edges as much as trims.
Aokia 12V cordless weed wacker with adjustable pole
The Aokia is the lightest pack-powered option in this set on the listing’s own figures, and it has the longest reach. Its two detachable pole sections give lengths of 32, 48 and 65 inches. The bullets describe a metal blade for thick weeds and a saw blade for branches, and the battery is listed as a 12V 2000mAh pack. The bullets give a weight of 3.72 pounds, while the specs table says 4.8 pounds, so confirm the weight before you buy. A single pack is a limit on long jobs.
Which battery setup to choose
For a small yard with a few weeds, a single pack with a 30-minute runtime, such as the Aokia, may be enough. For a larger yard, two packs matter more than the voltage label. Two-pack listings include the Ohey, MoYohos, Windpost, ALSO GO 24V, ALSO GO 21V and the BLACK+DECKER combo, and the swap lets you keep working while one pack charges. A single-pack trimmer with a longer stated runtime, such as the DCA, can also cover a large job without a swap.
The voltage label alone does not tell you much. The 21V, 24V and 20V MAX labels all describe nominal pack voltage, and the listings give their own runtimes. Compare the amp-hour rating and the stated minutes, not the voltage number on the box.
Head type: string or blade
String heads trim grass and edges, and blade heads cut weeds and light brush. The Ohey, MoYohos, Windpost and Aokia listings include steel or saw blades, while the BLACK+DECKER and ALSO GO 21V listings are built around string heads with automatic feed. If your yard has woody stems, a blade-capable model is the group to compare. The listings say saw blades are for small branches, not for trees, so a trimmer is not a substitute for a pruning tool.
Weight and shaft length
Weight matters on long jobs. The ALSO GO 24V lists three pounds, the Windpost lists 2.5 kilograms in its bullets, the BLACK+DECKER trimmer lists 4.5 pounds, and the DCA lists 7.6 pounds with its battery. Shaft length matters for reach and for back strain. The MoYohos shaft runs 35 to 47 inches, the Ohey 43 to 55 inches, and the Aokia can reach 65 inches with its longest pole. Pick the length that lets you keep your back straight.
Mistakes to avoid
- Buying a tool-only listing and expecting a battery. The DeWalt-compatible and Milwaukee-compatible listings say the battery is not included.
- Trusting the highest runtime number. The Ohey and FLYINGJOING figures are listing claims for alternating packs, and the single-pack figures are lower.
- Ignoring the head. A string head is wrong for thick brush, and a blade head is wrong for an edging job.
- Skipping the safety switch. Several listings use a dual safety switch, and the listings say to press both before starting.

FAQ
Is a battery weed eater the same as an electric one?
In these listings, yes in practice. Every model here runs on a rechargeable battery, and none is listed as corded. The word electric describes the motor, while the battery describes the power source.
How long does a battery weed eater run?
It depends on the pack and the listing. The DCA lists 60 minutes at low speed on a 4.0Ah pack, the ALSO GO 21V lists 40 minutes on two 2.5Ah packs, and the Ohey lists 90 to 120 minutes with two packs used alternately. Several listings do not give a runtime figure.
Which is better for thick weeds?
A blade-capable model with steel or saw blades. The MoYohos, Ohey and Windpost listings include them. A string-only head is better for lawn edges.
Are two batteries better than one?
For a large yard, yes. Two packs let you swap while one charges. The listings for the MoYohos, Ohey, Windpost, ALSO GO 24V and BLACK+DECKER combo all include two packs.
Can I use my own battery?
Only if the listing says so. The DeWalt-compatible listings and the Milwaukee-compatible listing are tool-only, and they name the battery models they accept.
Which model is lightest?
On the listing’s own figures, the ALSO GO 24V lists three pounds. The Aokia bullets give 3.72 pounds, and the specs table gives 4.8 pounds, so confirm the number before you buy.
Bottom line
Choose the battery setup first. If your yard is large, pick a model with two packs and a stated runtime you can use, then choose the head for the growth you cut. If you cut mostly edges and lawn, a string head with automatic feed is enough. If you cut thick weeds or brush, pick a blade-capable model with steel or saw blades. Confirm the weight and the battery in the full listing before you order.
