1.5 Million Ocoopa Hand Warmers Recalled After Fires and One Death
Federal regulators say the rechargeable warmers' lithium-ion batteries can overheat and ignite; the company has logged 15 fires and 350 burn injuries.
Ocoopa Direct has recalled about 1.5 million rechargeable hand warmers sold in the United States after the lithium-ion batteries inside them were found to overheat and catch fire, according to a recall announcement published July 30 by the Consumer Product Safety Commission.
The company has received 1,480 reports of the hand warmers overheating, resulting in 15 fires and 350 burn injuries. Those reports include the death of an 83-year-old consumer in San José, California, in February 2026. The CPSC said the batteries can overheat and ignite both during use and while charging, posing a risk of serious injury or death from fire and burn hazards.
The recall covers Ocoopa-branded rechargeable hand warmers with the model numbers UT3053, UT3056, ZLS-118, ZLS-118S, ZLS-118D, H01 and H01(PD). They were sold online at Amazon, Walmart, ocoopa.com and ocoopa.net from September 2018 through May 2026, at prices between $15 and $60.
The double-sided warmers were sold in a range of colors and designs, in packs of two that join magnetically, with a charging cable. Each unit has a USB-C charging port, adjustable heat settings, LED indicator lights and a silicone lanyard, with "OCOOPA" printed on top. The model number and a three-digit batch number are printed on the underside of each warmer.
What owners should do
Consumers who own a recalled model are told to stop using it immediately. To obtain a full refund — issued as a gift card or to the original payment method — owners must write "RECALLED" on the device in permanent marker and submit a photo of that marking, along with the model and batch numbers, through Ocoopa's product recall page.
Because the devices contain lithium-ion batteries, they should not be placed in household trash or ordinary recycling, and they should not be mailed back to the company. They must instead be taken to a household hazardous waste collection center. Local city or county public works departments can identify the nearest site, and the Environmental Protection Agency's website has a search tool for hazardous waste management facilities. Owners are advised to call ahead to confirm the center accepts defective lithium-ion batteries.
Disposable, air-activated warmers, which contain no batteries, are one alternative for cold-weather use.
