Verdict: Choose the electric side for mowing small lawns with battery tools and no fuel mixing. Choose the gas side for a mower plus a trimmer, if fuel upkeep is acceptable.
A property with lawn edges, fence lines and field edges needs different tools for different ground, and the electric vs gas string mower question comes down to what each listing actually includes.

Read the full review
The Litheli listing is a cordless lawn mower, not a string trimmer: a 20V mower with a 13 inch width, 5 height adjustments, a folding handle and an 8-gallon bag. The listing states 3400 RPM, 24 pounds and up to 1300 sq. ft. on a full charge. The battery figure is contradictory, so the 15 minutes battery life is the clearer limit.

- 3 years warranty for the whole machine, 1 year for the battery
- Mows up to 1300 sq. ft. on a full charge, per the listing
Cons
- Battery average life of 15 minutes limits longer sessions
- Plastic material and 13 inch width suit smaller lawns

Figures are manufacturer stated for the models below, collected 28 October 2026.
Power source: battery or gas
The electric listings run on batteries. The Litheli example uses a 20V battery, listed as 4.0Ah in the kit list, with a 13 inch width, and the Craftsman example uses 2 batteries at 4.0Ah with a 15 inch width and up to 45 minutes stated. Battery power means charging batteries, with no fuel to mix.
The gas listings are mower kits with different trimmer power. The SENIX example pairs a 201cc gas mower with a battery powered 10 inch string trimmer. The PowerSmart example pairs a 144cc gas mower with a 25.4cc gas string trimmer. The Craftsman listing states up to 45 minutes of runtime. The Litheli listing states 15 minutes of battery average life, which is a different measure, and no runtime is stated for the gas listings.
What each listing actually includes
Neither electric listing includes a string trimmer. The Litheli example is a cordless lawn mower with a folding handle and an 8-gallon bag, and the Craftsman example is a push mower with a grass bag, 2 batteries and 2 chargers.
Both gas listings include a trimmer. The SENIX example adds a 350 CFM blower at 80 MPH and a 21 inch hedge trimmer, while the PowerSmart example adds a 10 inch brush cutter blade and 0.095 inch trimmer line.
Handling and weight
Weight is stated for the Litheli example and the SENIX example only. The Litheli example weighs 24 pounds, while the SENIX example weighs 66 pounds as item weight. Weight is not stated for the other examples, so neither side can be called lighter as a whole.
Upkeep
Battery upkeep is charging and battery care. The Litheli listing states a 3 years warranty for the whole machine and a 1 year warranty for the battery, while the Craftsman listing states no warranty term. The Litheli maker lists its motor as low-maintenance and low-noise.
Gas upkeep is fuel and engine care. The SENIX listing states a 2-year warranty for the mower and a 5-year limited warranty on tools, with a 3-year warranty on battery and charger. The PowerSmart listing states no warranty term. Gas mowers need fuel with the engine off and cool, and trimmers need eye and hearing protection.

The Acre Score explained
The Acre Score weighs performance, build quality, value, safety and warranty. Safety scores zero for every example here, because no listing states a safety certification that the scoring counts. Warranty scores zero where the listing states no warranty term.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| SENIX 201cc combo | 9.6 | 30 | 21 | 21 | 0 | 4 |
| Litheli 20V mower | 9.4 | 26 | 19 | 20 | 0 | 4 |
| CRAFTSMAN V20 mower | 9.4 | 28 | 20 | 21 | 0 | 0 |
| PowerSmart 144cc kit | 9.4 | 27 | 21 | 19 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
Wear eye and hearing protection, long pants and sturdy footwear, and keep bystanders well back while the line or blade spins. Clear stones and debris first, and stop the engine or remove the battery before clearing the head. Refuel only with the engine off and cool. See OSHA landscaping safety. Read our Safety Disclaimer.
