Battery and platform

The ISD401 runs on Greenworks’ 24V POWERALL lithium-ion platform, which spans 200+ tools including lawn and garden equipment. For existing Greenworks owners, this means the two 2.0Ah USB-C batteries in the box already work with other tools you own. The batteries also function as USB power banks for charging phones and other devices. Recharging a 2.0Ah battery takes about 60 minutes on the included dual-port charger.

Torque and speed

The brushless motor is rated at 2650 in-lbs maximum torque and 2800 RPM no-load speed. Three electronic speed settings are labeled in newton-meters on the manufacturer page: 100 Nm, 200 Nm and 300 Nm. The 300 Nm setting corresponds to roughly 2655 in-lbs, aligning with the maximum torque claim. Greenworks’ Canadian marketing describes the tool as capable of driving 4" deck screws into pressure-treated lumber and handling lag bolts up to 1/2" diameter. These are manufacturer claims, not independent test results.

What owners say

Owner discussions specific to the ISD401 are sparse. General Greenworks 24V platform owners appreciate the battery compatibility across lawn and garden tools. Trustpilot reviews for Greenworks as a brand show recurring complaints about customer service responsiveness, warranty claim difficulties, and battery longevity issues. Reddit r/lawncare discussions describe Greenworks customer service as “terrible” with long hold times and unresponsive support. Reddit r/Greenworks discussions mention price adjustment refusals. These are brand-level signals, not ISD401-specific defect reports.

Is it worth it?

At $69.99 from Greenworks direct (marked down from $139.99, as of October 2026), the ISD401 offers strong value: 2650 in-lbs torque, brushless motor, two batteries, charger, and 24V platform compatibility. The lack of independent testing and sparse owner history are acceptable tradeoffs at this price. At $81-110, compare with Ryobi, DeWalt, and Milwaukee entry-level kits that may have stronger test histories. Above $110, the value weakens unless the Greenworks 24V battery ecosystem is a deciding factor.
