Greenworks Tools has recalled about 554,780 Kobalt 24V and 48V yard power tools beacuse the lithium-on battery can overheat, which poses a fire hazard and a risk of serious injuries or death.
The recall covers a wide range of Kobalt-branded outdoor power tools that use lithium-ion batteries with a USB-C charging port. These products include string trimmers, blowers, mowers, chainsaws and pruning saws. Only products sold with the USB-C batteries are being recalled.
