OCOOPA rechargeable lithium-ion battery hand warmers are being recalled because they can overheat and ignite, posing a risk of serious injury or death from fires and burns.
OCOOPA Direct has received 1,480 reports of hand warmers overheating, resulting in 15 fires and 350 burn injuries, including the death of an 83-year-old consumer in San José, Calif. in February 2026.
The recall includes models:
- UT3053
- UT3056
- ZLS-118
- ZLS-118S
- ZLS-118D
- H01
- H01(PD)
The hand warmers were sold in varying colors and designs. They were sold in pairs that can magnetically be joined and include a charging cable.
The adjustable-heat hand warmers have LED indicator lights on the hard plastic shell and a silicone lanyard. “OCOOPA” is printed on the top of the hand warmers and on the product packaging.
Consumers can find the model number and three-digit batch number printed on the underside of each hand warmer.
About 1.5 million hand warmers were sold online at Amazon.com, Ocoopa.com, Ocoopa.net, and Walmart.com from September 2018 through May 2026. The cost was between $15 and $60. The products were manufactured in China.
Consumers should stop using the recalled hand warmers immediately, the company and U.S. Consumer Product Safety Commission, or CPSC, advise, and contact OCOOPA Direct for a refund that will be an OCOOPA gift card or the original form of payment.
Consumers are asked to write in permanent marker “RECALLED” on the hand warmer and submit a photo showing that marking on it, the model number, and the product’s three-digit batch number to https://www.ocoopa.com/pages/product-recalls.
Consumers should dispose of recalled products with the lithium-ion battery according to local and state hazardous waste regulations.
The CPSC urges consumers to report any related incidents to the agency at www.SaferProducts.gov.
