Greenworks Tools is recalling about 554,780 Kobalt-branded yard power tools and lithium-ion batteries after dozens of reports of batteries smoking, sparking or catching fire while charging, according to the U.S. Consumer Product Safety Commission.

The voluntary recall covers select Kobalt 24V and 48V outdoor power equipment sold with USB-C rechargeable batteries, including string trimmers, leaf blowers, lawn mowers, chainsaws, pruning saws, power cleaners and other tools.

The CPSC said charging the lithium-ion batteries through the USB-C port while the batteries remain inserted in the tool can cause the battery to short-circuit, creating a fire hazard that poses a risk of serious injury.

The recalled products were sold at Lowe's stores nationwide and online at Lowes.com between January 2026 and May 2026. Prices ranged from about $20 for standalone batteries to $482 for complete tool kits.

Only Kobalt products equipped with the recalled USB-C batteries are included in the recall. The affected batteries were sold in 3.0Ah, 4.0Ah, 5.0Ah, 6.0Ah and 8.0Ah capacities. Certain 3.0Ah and 6.0Ah batteries were also sold separately.
