This Greenworks 40V combo brings together a 12 inch string trimmer and a 390 CFM blower around a shared 2.0 Ah battery. It is aimed at light to medium lawn care like walkway edges, flower beds, patios, and leaf cleanup.
This review checks the listed features and specs, including auto feed, blower cruise control, weight, noise, and battery logistics. The assessment is based only on the supplied product listing.
Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
Pairs a 12 inch string trimmer with a 390 CFM blower to cover cutting and clearing in one kit.
Uses 0.065 inch line and auto feed to keep the 12 inch cut path working without manual bumping.
Maintains a set airflow for gutter and driveway work without holding the trigger continuously.
The included 2.0 Ah pack charges in about 60 minutes and works with the wider Greenworks 40V family.
Approximately 8 lb tool weight and 67 dB noise help with longer sessions and early morning use.
Design and Build Quality
The combo uses a green and black finish and a balanced lightweight frame, with the trimmer and blower both built around the same 40V battery platform. The trimmer head carries a 3 year warranty, which is a useful sign for the auto feed mechanism.
The blower includes cruise control to hold airflow without constant trigger pressure. The listing does not confirm the exact materials or tool dimensions, so durability claims are limited to the listed warranty and design features.
Performance in Everyday Use
The trimmer is listed to handle weeds up to 1 inch thick with a 12 inch cut path and 0.065 inch auto feed line. The blower is rated at 390 CFM and 110 MPH, which should move wet leaves and debris on hard surfaces.
One real limitation is battery stamina: the 2.0 Ah pack is on the smaller side for a 40V system, so larger properties or dense brush may require planned charging breaks. The 8 lb weight and 67 dB noise help with comfort during typical 2 hour sessions, but real world runtime depends on load and technique.
How It Performs: The Evidence
| Decision factor | What we found | Evidence and measurement | Score | Why it matters |
|---|---|---|---|---|
| Trimming width | 12 inch cut path | Listing feature bullet | 8.0 | Decent for edging and light brush, not the widest in class. |
| Trimmer line feed | 0.065 inch auto feed | Listing feature bullet | 8.5 | Auto feed reduces manual bumping, with 3 year head warranty. |
| Blower output | 390 CFM and 110 MPH | Listing feature bullet | 8.0 | Middle of the 40V range for hard surfaces and wet leaves. |
| Weight and noise | About 8 lb and 67 dB | Listing feature bullets | 8.5 | Comfortable for longer sessions and early morning work. |
| Battery stamina | 2.0 Ah pack with 60 minute charge | Listing title and feature bullet | 6.5 | Small for a 40V system; big jobs need extra packs or breaks. |

This review is based on the manufacturer's stated specifications, the current Amazon product listing and its images, the confirmed materials and design, and our own research into string trimmers as a product category. Our scores are editorial judgments made against consistent criteria, not laboratory measurements, and we did not carry out destructive or long-term stress testing.
