Safety officials tell owners to throw out 1.5 million hand warmers after a death

A rechargeable pocket warmer that sold in the millions has been recalled after its battery was linked to a fatal fire, and the safety instructions go further than a typical refund notice. Regulators are telling owners not just to stop using the devices but to dispose of them as hazardous waste, because the lithium-ion cells inside can overheat and ignite. The action, announced at the end of July 2026, covers roughly 1.5 million hand warmers sold over nearly eight years through some of the largest online retailers in the country.

The recall stands out both for its size and for the number of incidents behind it. Long before the formal notice, the manufacturer had already logged well over a thousand overheating complaints, a trail of reports that culminated in the death of an elderly consumer.

Why owners are told to throw the hand warmers away

The recall published by the Consumer Product Safety Commission states that the lithium-ion battery in the hand warmers can overheat and ignite, posing a risk of serious injury or death from fire and burn hazards. Unlike a refrigerator or appliance that can be repaired, a defective lithium-ion cell cannot be made safe in place, which is why the remedy is a refund paired with disposal rather than a fix.

The disposal instructions are unusually specific. The commission warns that the devices must not be thrown in the regular trash, placed in curbside recycling bins, or dropped into the used-battery collection boxes found at many retail and home-improvement stores. Instead, owners are directed to their municipal household hazardous waste program, and to call ahead to confirm the facility accepts defective lithium-ion batteries. That caution reflects a broader problem: damaged or defective lithium cells have started fires in garbage trucks and recycling centers, so the wrong disposal route can simply move the hazard downstream.

1,480 overheating reports and one death

The company behind the product received 1,480 reports of hand warmers overheating, which resulted in 15 fires and 350 burn injuries, including the death of an 83-year-old consumer in San Diego, California, in February 2026. That volume of complaints is what elevates the recall from a precaution to an urgent warning, and the burn-injury count in particular signals that many users were harmed even in incidents that did not become full fires.

The single fatality anchors the recall. A product that has already been tied to a death carries a different weight than one flagged only for potential risk, and it typically drives regulators to push the notice out widely and quickly. The commission is asking consumers who have experienced any related incident to report it through the government’s product-safety channels so that officials can continue tracking the failures.

The OCOOPA models covered by the recall

The recall involves OCOOPA-branded rechargeable lithium-ion hand warmers in models UT3053, UT3056, ZLS-118, ZLS-118S, ZLS-118D, H01 and H01(PD). The dual-sided warmers were sold in a range of colors and designs, typically in packs of two units that can be magnetically joined, and they charge through a USB-C port. Owners can find the model number and a three-digit batch number printed on the underside of each device, alongside the OCOOPA name on the top of the unit and on the packaging.

Because the warmers were marketed as a cold-weather convenience item and sold in seasonal waves, many households may own more than one, and some may be stored away out of season rather than in daily use. Regulators generally note that products tucked in drawers or winter gear are the hardest to reach with a recall notice, which raises the risk that some defective units will remain in circulation.

How to get a refund from OCOOPA

To claim the remedy, consumers are told to stop using the hand warmers and contact the importer, which is doing business as OCOOPA Direct, for a full refund issued either as a gift card or in the original form of payment. The process asks owners to write the word “RECALLED” on the device in permanent marker and submit a photo showing that marking, along with the model and batch numbers, through the company’s product-recall page. That verification step is common in refund-based recalls because it confirms the hazardous unit has been taken out of service.

Owners who no longer have proof of purchase are still generally eligible under the terms described, since the marking and photo serve as the record. The refund and the disposal requirement work together: the goal is to compensate buyers while ensuring the defective battery is routed to a facility equipped to handle it safely.

Where the hand warmers were sold

About 1.5 million of the hand warmers were sold online at Amazon, Ocoopa.com, Ocoopa.net and Walmart from September 2018 through May 2026, for prices ranging from $15 to $60. The devices were manufactured in China and imported by Shenzhen Street Cat Technology. Consumers who want to report an incident or search for other flagged products can do so through the federal SaferProducts.gov database. For anyone who recognizes one of the covered models, the guidance is unambiguous: stop charging it, claim the refund, and dispose of the battery through a hazardous-waste channel rather than the trash.
