The United States Consumer Product Safety Commission (CPSC) has announced a recall of about 1.5 million OCOOPA rechargeable hand warmers because their built-in lithium-ion batteries can overheat and ignite, posing serious fire and burn hazards.
OCOOPA Direct has received 1,480 reports of the hand warmers overheating, resulting in 15 fires and 350 burn injuries. An 83-year-old consumer in San Diego, California, died in February 2026 after an incident involving one of the recalled hand warmers.
The affected OCOOPA rechargeable hand warmers were sold online at Amazon.com, Ocoopa.com, Ocoopa.net, and Walmart.com from September 2018 through May 2026 for between $15 and $60.
The specific models affected are listed below.

The recalled dual-sided hand warmers were sold in various colors and designs in packs of two. The two warmers can be magnetically joined, and each has a USB-C port for charging its built-in lithium-ion battery. They also have adjustable heat settings, LED indicator lights, a hard plastic shell, and a silicone lanyard.
“OCOOPA” is printed on the top of the hand warmers and on the product packaging. You can find the model number and three-digit batch number on the underside of each hand warmer.
If you own any of these products, stop using them immediately, as they are a serious fire and death hazard. The company recall page has details on how to submit a claim for a full refund.
To submit a claim for a full refund, consumers are instructed to write “RECALLED” on the hand warmer with a permanent marker and submit a photo showing the marking, model number, and three-digit batch number. OCOOPA has set up a product recall page with complete instructions for submitting a claim. Check it out here.
Remember, never dispose of a recalled hand warmer in household trash, curbside recycling, standard battery recycling boxes, or other general recycling streams. Defective lithium-ion batteries pose an increased fire risk and require special handling.
Contact your local household hazardous waste collection center before bringing the hand warmer there to confirm that it accepts defective lithium-ion batteries. If it does not, contact your municipality for guidance on proper disposal under applicable local and state hazardous waste regulations.
Consumers who have experienced an incident involving one of the recalled hand warmers can also report it to the CPSC.
