Burn Hazard Prompts Recall of HotHands Rechargeable Hand Warmers 2026

A lithium-ion battery that can overheat and ignite is the danger behind a newly announced recall of HotHands Rechargeable Hand Warmers sold in Canada and the United States. Health Canada published the recall notice on October 1, 2026, as a joint action with the U.S. Consumer Product Safety Commission and the distributor, Kobayashi Consumer Products, LLC, of Dalton, Georgia.

If you bought a set of these warmers for winter, the advice is simple: stop using them now. The recall covers products sold from July 2025 to August 2026, so many units may already be in coats, gloves boxes and gear bags.

• Product: HotHands Rechargeable Hand Warmers
• Model number: H163650
• Hazard: Battery and electrical components can overheat and ignite, posing a burn hazard
• Units sold: 72 in Canada and 77,000 in the United States
• Sold: July 2025 to August 2026
• Recall number: RA-82676

Products Affected by This Recall

The recall involves HotHands Rechargeable Hand Warmers in white with orange trim. They were sold in packs of two warmers that can be joined together magnetically, and each pack includes a charging cable.

Each warmer has a USB-C port used to charge its built-in lithium-ion battery. The adjustable-heat units have LED indicator lights on a hard plastic shell and come with a silicone lanyard. The white HotHands logo appears on the top of the warmers and on the product packaging.

To check whether your warmers are included, look at the underside of each unit. The model number H163650 and a batch number are printed there.

What Triggered the Recall

According to Health Canada, the lithium-ion battery and electrical components in the recalled product can overheat and ignite. That creates a burn hazard for anyone holding, carrying or charging the warmers.

As of September 14, 2026, the company had received no reports of incidents or injuries in Canada or the United States. In other words, the recall is a preventive step based on the identified risk rather than a response to confirmed harm.

Even so, heat-producing devices powered by lithium-ion batteries are often kept close to the body, in pockets, or inside gloves and jackets. That is why a fault that could lead to overheating is treated seriously by regulators.

Who Should Be Concerned

Anyone who purchased HotHands Rechargeable Hand Warmers during the sales window should check their units. The company reported that 72 units were sold in Canada and 77,000 were sold in the United States. The product was manufactured in China.

Because the warmers are often bought as winter gifts, people who received a set as a present should also check the underside of the product for the model number.

Steps Consumers Should Take

Health Canada says consumers should immediately stop using the recalled product and contact Kobayashi to obtain a refund. Here is how the process works:

• Stop using the hand warmers and stop charging them right away.
• Visit the recall website at hothandsrechargeable.expertinquiry.com and follow the instructions to process your refund.
• After completing the refund process, dispose of the items safely so that they cannot be used again.
• Contact your municipality for instructions on how to safely transport and dispose of lithium-ion batteries.
• Do not place the batteries in household garbage, because they are considered hazardous waste.

For more information, consumers can call Kobayashi at 1-866-534-9986, from 8 a.m. to 5 p.m. ET, Monday through Friday. Questions can also be sent by email to kobayashi5236@sedgwick.com, or consumers can visit the company recall page at hothands.com/recall-notice-rechargeable.

Regulatory Response

The recall was issued jointly by Health Canada, the U.S. Consumer Product Safety Commission and Kobayashi. Health Canada reminded the public that the Canada Consumer Product Safety Act prohibits recalled products from being redistributed, sold or even given away in Canada.

The agency also encourages consumers to report any health or safety incident involving this or any other consumer product by filling out the Consumer Product Incident Report Form. The recall is also listed on the OECD Global Portal on Product Recalls.

Health Canada’s notice lists a related recall of OCOOPA rechargeable hand warmers over a fire hazard, a reminder that shoppers should keep an eye on safety notices for portable heated products this season.

Consumers who are unsure whether their warmers are affected should check the underside for the model number and err on the side of caution until they have confirmed it.
