Kobalt battery recall flags USB-C charging fire risk

A tool-battery recall in the US can feel like somebody else’s paperwork. Then picture the normal shed scene: line trimmer in the corner, pack still clipped in, USB-C lead dangling, lights off while everyone heads inside. That is why the Kobalt battery recall is worth a look from here. Greenworks has recalled about 554,780 Kobalt-branded 24V and 48V yard-power tools and batteries sold through Lowe’s in the US after reports that packs could short-circuit while charging through the USB-C port with the battery still sitting in the tool.

The useful numbers are plain enough. The CPSC notice lists 34 reports of batteries producing smoke, sparking or catching fire. It says no injuries and no property damage have been reported so far. That is better than the alternative, but it is still the kind of warning you want before a hot pack gets its chance in a shut garage, under a bench or beside the cardboard pile you swear you will break down this weekend.

The charging setup is the part to clock. These batteries were being charged while still in the product. Convenience is the whole pitch with gear like this: plug it in where it sits, top it up, move on. It also nudges blokes into a crook habit. Cordless kit gets left on charge because it feels closer to charging a phone than dealing with a tool battery. In this case, Greenworks’ own recall page tells owners to immediately stop charging the batteries while they are inserted in the product.

That keeps the geography honest. This is not an Australian recall notice. The affected Kobalt tools were sold in the US from January to May 2026, with prices ranging from US$20 to US$482. The lesson still travels. If you have bought US-market Kobalt gear through imports, resale channels or the usual marketplace rabbit holes, check the model and battery details against the recall list. If another cordless platform in your shed uses in-tool charging, have a proper look at where that battery sits while it is topping up and whether anyone would notice smoke quickly.

What shed owners should do now

Check whether your gear is part of the recall and follow the replacement steps on the official Greenworks recall page. Stop charging any affected battery while it is clipped into the tool. That is the clear instruction from both manufacturer and regulator. For the rest of the shed, treat this as a charger tidy-up. Put packs somewhere heat, smoke or sparks will be noticed early. Keep chargers away from loose cardboard, rags and half-open boxes of screws. If a battery runs unusually hot, swells or smells off, stop using it and park the job until you know what is happening.

Battery-platform decisions are about more than torque numbers, runtime claims and a cheap skin-only deal on a Saturday morning. Charging design matters. So does the spot where the pack lives when no one is watching it. We would not panic about every USB-C-equipped tool that turns up in yard and shed gear. We would stop treating tool batteries like phone accessories. A recall that catches 34 incidents before injuries is the kind of warning smart owners use to clean up the habit early.
