Massive cordless tool battery recall over USB-C charging risk
The cordless tool battery recall USB-C 2026 story starts with a simple convenience feature that went wrong. The United States Consumer Product Safety Commission, or CPSC, announced that more than 554,000 Kobalt yard power batteries with a USB-C port for USB charging are being recalled because they can overheat and catch fire when charged through USB-C while the batteries are inserted in compatible tools. For drill and driver owners who now expect every lithium-ion battery to charge like a phone, this recall is a warning shot rather than a niche yard equipment issue.
The recalled products are 24 volt and 48 volt Kobalt battery packs with built-in USB-C ports, manufactured by Greenworks Tools and sold at Lowe’s in kits and as standalone products for lawn and yard power equipment. The recall covers trimmers, blowers, chainsaws, pressure washers and propelled lawn mowers, along with other lawn tools that share the same lithium-ion battery platform, and the CPSC recall number 26-123 ties the hazard directly to USB-C charging while the Kobalt pack remains locked into the housing. CPSC reports 34 incidents of smoke, melting, sparks or fire but no reported injury so far, although the agency flags a serious risk of property damage if the fire starts in a garage or attached workshop.
According to the CPSC notice, announced January 8, 2026, affected Kobalt USB-C batteries include model numbers KB 624-03, KB 624-04, KB 648-06, KB 648-07, KB 624-05 and KB 648-08, sold both as replacement packs and bundled in yard power kits. The official recall bulletin, titled “Greenworks Recalls Kobalt 24-Volt and 48-Volt Battery Packs with USB-C Ports Due to Fire Hazard,” specifies that the action covers all date codes and serial ranges for those models. For homeowners who mainly think about cordless drill sets, the cordless tool battery recall USB-C 2026 matters because the failure mode is exactly how many people already treat their power tools. You grab a drill or impact driver, leave the batteries inserted in the tool, plug a cable into the USB-C port and walk away, trusting the product label more than the physics of a stressed lithium-ion cell. When a Kobalt yard tool pack can ignite under that pressure, it is not hard to imagine the same design flaw migrating into compact drill kits and combo products that live on basement shelves next to paint cans and solvent.
How the Kobalt USB-C flaw works and why drill owners should care
At the heart of the cordless tool battery recall USB-C 2026 is a design that lets the same battery charge through both a slide pack charger and a USB-C cable, even while the battery is locked into a tool drawing standby power. When USB-C charging happens with batteries inserted in a blower, trimmer or lawn mower, the pack’s internal electronics juggle tool demand, cell balancing and external power, which raises cell temperature and electrical pressure inside the case. Greenworks and Kobalt told CPSC that this combination can cause an internal short, leading to venting, smoke or fire, and that is why the recall covers every affected model number rather than just a narrow production run.
For drill platforms, the lesson is simple but uncomfortable, especially as more brands experiment with batteries that include USB-C ports and phone-style charging. A lithium-ion battery designed for high current power tools is not the same product as a phone pack, even if both use a USB-C connector, and mixing tool load with USB-C charging in one compact housing adds failure points that do not show up in glossy kit marketing. If you are eyeing a new compact drill kit with a built-in USB charging feature, or a premium pack like the DeWalt FlexVolt tabless 12 Ah battery highlighted in this tabless battery race analysis, you should ask whether the pack can be charged while seated in the tool and how the brand manages that thermal and electrical pressure.
The Kobalt battery recall number issued through CPSC specifies that the remedy is a free replacement battery without any USB-C port, plus a charger adapter and prepaid return label, which shows how seriously regulators treat even a modest number of fire reports. Greenworks Tools and Kobalt have recalled both individual batteries and full yard power kits, including propelled lawn tools and pressure washers, because the same lithium-ion battery architecture runs across multiple products and yard equipment. For drill owners, that breadth matters, since the same kind of cross-platform battery sharing is exactly what makes modern power tools convenient, but it also means a single design flaw can ripple through every tool on the platform.
What cordless drill users should check and safer ways to charge
For a DIYer with a cordless drill set on the bench, the cordless tool battery recall USB-C 2026 raises three immediate questions about existing batteries and future purchases. First, look at every battery in your kit and ask whether any Kobalt battery or third-party pack includes a USB-C port or USB charging feature that encourages you to leave batteries inserted in the drill while plugged into the wall. Second, check the label for a clear model number and any recall number or CPSC notice, especially if you bought Kobalt or Greenworks yard power tools, a propelled lawn mower or pressure washers that share packs with your drill or impact driver.
Third, change your charging habits so the battery comes off the tool and onto a dedicated charger every time, even if the product marketing promises phone-style convenience. A standalone charger isolates the lithium-ion cells from tool electronics, reduces electrical pressure on the pack and makes it easier to notice swelling, heat or other warning signs before a fire or property damage event, which is exactly what regulators want to see after this wave of recalled products. If you are evaluating new power tools or replacement batteries, guides on topics like battery housing changes and fit checks can help you match the right kit to your drill without leaning on risky USB-C charging shortcuts.

The cordless tool battery recall USB-C 2026 is a reminder that a battery, whether in singular or multiple batteries form, is not just a replaceable consumable but the heart of every cordless tool, from a compact driver to a 21 inch lawn mower. In the end, the drill you trust is not the one with the biggest power number on the box, but the one whose battery stays cool and predictable on the tenth deck screw at a frozen 6 a.m. start.
