WASHINGTON, DC — About 77,000 HotHands rechargeable hand warmers are being recalled because of a possible fire and burn hazard, according to the U.S. Consumer Product Safety Commission. The agency said the affected units contain lithium-ion batteries and electrical components that can overheat and ignite, creating a risk of serious injury.
The recall was announced Oct. 1 and covers rechargeable warmers distributed by Kobayashi Consumer Products. Officials said the company is offering consumers a full refund and asking them to stop using the devices right away.
Which HotHands warmers are included in the recall
The recalled products are white and orange, carry the HotHands logo and were sold in packs of two. The model number is H163650, which is the identifying number consumers should check before taking any action.
The recall applies only to the rechargeable electric hand warmers. Traditional disposable HotHands products are not part of the notice, according to the company and the safety commission.
That distinction matters because the HotHands name appears on multiple consumer products, but only the rechargeable version is covered by this recall. Buyers who own the disposable type do not need to follow the recall instructions tied to this model.
Where the hand warmers were sold and for how much
The warmers were sold nationwide at Target, The Home Depot, Bass Pro Shops, Amazon and other retailers. Sales ran from July 2025 through August 2026, with prices listed at about $30 to $40.
Because the devices were widely distributed across major chains and online marketplaces, the recall affects shoppers in many states. Consumers who purchased the product during that window should compare the package and model number with the recall details.
Retailer names and the long sales period make it more likely that the warmers may still be in homes, cars or travel bags. The commission is urging people to check any rechargeable HotHands units they own before using them again.
Why regulators say the batteries pose a danger
The CPSC said the hazard comes from the hand warmers’ lithium-ion batteries and electrical components. If those parts overheat, the devices can ignite and cause burns or other injuries.
That risk is the central reason for the recall, even though no incidents or injuries had been reported in the recall notice. The agency uses recall notices to reduce the chance that a product flaw turns into a reported injury later.
Lithium-ion batteries are common in many consumer electronics, but they require careful handling and safe disposal. In this case, officials are warning consumers not to treat the recalled warmers like ordinary household waste.
What consumers should do with the recalled warmers
People who have the recalled warmers should stop using them immediately and contact Kobayashi Consumer Products for a full refund. Refund instructions are available on the official HotHands recall website or by calling 866-534-9986.
The company is also warning consumers not to throw the devices in household trash or put them in regular recycling bins. Because the warmers contain lithium-ion batteries, they should be taken to a local household hazardous waste facility for disposal guidance.
Consumers should keep the units out of normal waste streams until they get directions from the appropriate local facility. That helps reduce the chance of fire during handling, transport or disposal.
What this recall means for shoppers who bought HotHands products
The notice is limited to a specific rechargeable model, but it is broad enough to affect customers who bought the warmers at several major retailers over more than a year. Anyone who picked up a two-pack of rechargeable HotHands units should verify the model number before using them again.
Shoppers who have questions about whether their product is included can check the recall information through the official channels listed by Kobayashi. The company says the refund process is available to affected consumers now.
For buyers, the main takeaway is simple: if the warmer is the rechargeable model H163650, stop using it and follow the refund and disposal steps. If it is a disposable HotHands product, it is not covered by this recall.
