The OCOOPA brand name is printed on the top of the devices, while the model number and three-digit batch number appear printed on the underside.
The recalled hand warmers were sold online through Amazon.com, Ocoopa.com, Ocoopa.net and Walmart.com between September 2018 and May 2026 for between $15 and $60. The products were manufactured in China.
Consumers asked to stop using recalled hand warmers
What’s next:
Consumers are urged to stop using the recalled hand warmers immediately.
OCOOPA Direct is offering affected consumers a full refund, either as an OCOOPA gift card or through the original method of payment. To receive a refund, consumers must write the word “RECALLED” on the hand warmer with a permanent marker and submit a photograph showing the marking, along with the product’s model number and three-digit batch number, through the company’s online recall portal.
Because the products contain defective lithium-ion batteries, consumers should not throw them in household trash, curbside recycling bins or standard battery recycling collection boxes. Instead, the batteries should be disposed of through a local household hazardous waste collection center or another approved disposal method in accordance with local and state regulations.
The CPSC is also encouraging consumers to report any additional incidents involving the recalled hand warmers through SaferProducts.gov.
