A popular brand of rechargeable hand warmers can overheat and catch fire, and the maker just recalled more than 77,000 of them nationwide.
Quick Take
- Kobayashi recalled HotHands Rechargeable Hand Warmers, model H163650, over fire and burn risks tied to the lithium-ion battery and electrical parts.
- About 77,000 units sold nationwide from July 2025 through August 2026 are affected, sold at Target, Meijer, Bass Pro Shops, The Home Depot, and online for $30 to $40.
- Consumers must stop using the warmers right away and can get a full refund from Kobayashi after marking the product “Recalled” and submitting photo proof.
- The recall is often grouped with a separate Gobi Heat hand warmer recall, bringing the combined total to more than 82,000 units nationwide.
What The Official Recall Notice Says
The U.S. Consumer Product Safety Commission announced the recall on October 1, 2026. The notice warns that the lithium-ion battery and electrical components inside the HotHands warmers “can overheat and ignite.” That creates what the agency calls “a risk of serious injury from fire and burn hazards.”
Kobayashi Consumer Products, LLC is the company behind the recall. Its own recall page identifies the exact model affected: H163650. The company says it sold the rechargeable warmers from July 2025 through August 2026, meaning anyone who bought one in roughly the past year should check their product right away.
Local news coverage has helped spread the word as cold weather sets in, a season when these products see heavy use. Buffalo’s WGRZ reported the units were sold nationwide and online, confirming the $30 to $40 price point and listing Bass Pro Shops, Meijer, Target, and The Home Depot as retail sellers.
How Consumers Can Get Their Money Back
Kobayashi is not offering a repair or a replacement part. The fix is simple: stop using the warmer immediately and get a full refund. The company has set up phone, email, and online claim channels to process those refunds.
The process requires a few extra steps before a refund ships. Consumers need to get a claim number from Kobayashi, then write “Recalled” along with that claim number directly on the product. They also have to snap a photo showing the marking next to the model and batch numbers before mailing in or submitting the claim.
Those steps exist for a good reason. A recall only works if consumers actually act on it. Government data on past recalls shows response rates can swing wildly, from single digits up to around a third of buyers, depending on how clear the instructions are and how easy the remedy feels. Extra paperwork can cut into that number.
Why This Recall Gets Bundled With Another Brand
Some coverage lumps this recall together with a separate action involving Gobi Heat hand warmers, producing headlines citing more than 82,000 units total. That combined figure comes from adding the HotHands count to the Gobi Heat numbers, even though they are two different companies with two separate recall notices.
Shoppers should not assume every rechargeable hand warmer in their drawer is affected. The safest move is checking the model number printed on the unit itself against the H163650 designation Kobayashi has published, rather than relying on a combined headline number that mixes two brands.

A Familiar Pattern With Small Rechargeable Devices
Hand warmers join a long list of compact lithium-ion gadgets that have faced recalls for the same basic reason. Battery cells, charging circuits, and wiring packed into a small plastic shell can fail in ways nobody notices until the device gets hot in a pocket or on a nightstand.
A product does not need a high failure rate to justify a recall. Even a small number of overheating incidents can be enough, because the worst-case outcome involves fire or burns. That calculus explains why agencies act quickly once a hazard like this gets confirmed, rather than waiting to tally a long list of injuries first.
Anyone who bought a HotHands rechargeable warmer in the last year should check it now, before the coldest months push it back into daily use. Confirming the model number takes thirty seconds and could prevent a far worse outcome later in the season.
