Federal regulators are urging owners of roughly 1.5 million rechargeable hand warmers sold through Amazon and Walmart to stop using them immediately after the devices were linked to hundreds of burns, multiple fires, and a fatal blaze in California.
The U.S. Consumer Product Safety Commission announced the recall of Ocoopa rechargeable hand warmers after the company, Ocoopa Direct, confirmed it had received 1,480 reports of the devices overheating. Those reports include 15 fires, 350 burn injuries, and the death of an 83-year-old consumer in San Jose, California, following a fire involving one of the hand warmers in February 2026.
Seven model numbers are covered by the recall: UT3053, UT3056, ZLS-118, ZLS-118S, ZLS-118D, H01, and H01(PD). The products sold online through Amazon.com, Walmart.com, and Ocoopa's own websites at prices ranging from $15 to $60, the Daily Mail reported. Sales stretched from September 2018 through May 2026, meaning the devices have been in consumers' pockets, glove compartments, and coat drawers for as long as eight years.
The hazard centers on the hand warmers' lithium-ion batteries, which can overheat and ignite. Consumer safety experts describe the failure mode as "thermal runaway", a chain reaction in which a damaged or defective battery cell heats itself faster than it can cool, eventually catching fire or bursting. Once thermal runaway begins, the device can go from warm to burning in seconds.
That risk makes even disposing of the recalled units dangerous. The CPSC warned consumers not to toss the devices into household trash, curbside recycling bins, or standard battery recycling boxes. Instead, the agency directed owners to bring the hand warmers to a local household hazardous waste collection facility or follow their state and local disposal regulations.
Ocoopa Direct is operating an online recall portal where consumers can submit a claim for a refund. The company says it will return the money to the original payment method or issue an Ocoopa gift card.
The most serious incident tied to the recall occurred in San Jose, California. An 83-year-old consumer died after a fire involving one of the recalled hand warmers in February 2026. The CPSC has not publicly detailed whether the death occurred at the scene or later, and it remains unclear whether a coroner or medical examiner has formally attributed the cause of death to the device. Ocoopa Direct confirmed the fatality as part of its incident reporting.
Beyond that single death, 350 people reported burn injuries, a staggering figure for a product designed to sit in a user's hand or rest against the body for warmth. The 1,480 overheating reports suggest the problem is not isolated to a handful of defective units. With 1.5 million hand warmers in circulation, the ratio of complaints to units sold points to a systemic defect rather than user error.
The CPSC flagged lithium-ion battery failures as one of the fastest-growing product safety concerns in the country. The agency is increasingly urging consumers to register rechargeable products at the time of purchase and to monitor recall notices, advice that amounts to an admission that federal regulators often cannot catch dangerous products before they reach millions of homes.
The commission also encouraged anyone who experienced an incident with the recalled hand warmers to file a report through the CPSC's SaferProducts database. That database relies heavily on consumer submissions, which means the 1,480 overheating reports and 350 burn injuries already on file may undercount the true scope of the problem.
Several questions remain unanswered. The CPSC has not specified whether the recall was voluntary, initiated by Ocoopa Direct, or mandatory. It is also unclear whether all seven model numbers carry equal risk or whether certain models account for a disproportionate share of incidents. And consumers have not been told precisely what manufacturing or design defect caused the batteries to fail, only that they can overheat and ignite.
Consumers who own any of the seven recalled models should stop using them now, keep the devices away from flammable materials, and follow the CPSC's disposal guidance to the letter. A $15 gadget is not worth a house fire, or worse.
