Two brands of lithium-ion hand warmers were recalled this month due to the risk of serious injury, according to notices published by a federal agency.

The recalls impact Kobayashi’s HotHands-branded rechargeable hand warmers and Gobi Heat Rechargeable Hand Warmers sold in North America.

The HotHands recall includes around 77,000 units sold in the United States and approximately 72 units sold in Canada, according to the Consumer Product Safety Commission (CPSC). Meanwhile, around 5,500 of the Gobi Heat units were sold in the United States, while around 47 were sold in Canada, the agency said.

Both items were manufactured in China, the Oct. 1 CPSC notices said.

For both the Gobi and Kobayashi items, the CPSC included the same warning: both hand warmers’ lithium-ion batteries and electrical components could overheat and ignite, posing a risk of serious burns and fire hazards.

The Kobayashi HotHands are white and orange, sold in packs of two warmers that can be joined magnetically, including a USB-C charging port for the lithium-ion batteries in each unit. They have LED indicator lights on the plastic shell.

The model number H163650 and batch number are written on the underside of the warmer, according to the notice. The white HotHands logo is located on the top of the unit and on the packaging of the product.

The Gobi Heat warmers were sold in packs of two that can be magnetically joined and also include a USB-C charging cable for the lithium-ion batteries, the CPSC notice said. They have LED lights on the plastic shell and come with a lanyard.

The text “Gobi Heat” is printed on the top of the warmers and on the packaging of the product. The model number UT3053 is written on the bottom, it said.

The notices say consumers should not use the recalled warmers.

For the HotHands products, consumers should contact Kobayashi for a full refund by going to the company’s recall page and following the instructions there. The products should be destroyed by consumers by writing “recalled” in a permanent marker and the claim number of the product before submitting a photo of the market item, the model number, and the batch number, which is four digits.

“Consumers should then dispose of the recalled product with the lithium-ion battery, in accordance with applicable local and state hazardous waste regulations,” it said.

For the Gobi Heat warmers, consumers can contact Gobi Heat by going to its recall website to get a claim number as well as similar instructions on how to destroy the hand warmers.

The HotHands notice warned: “Do not throw this recalled lithium-ion battery or device in the trash, the general recycling stream, or used battery recycling boxes found at various retail and home improvement stores.”

The reason, it said, is that lithium-ion batteries have to be disposed of differently from normal batteries due to the higher risk of fire they pose.

“Your municipal household hazardous waste (HHW) collection center may accept this recalled lithium-ion battery or device for disposal,” it advised. “Before taking your battery or device to a HHW collection center, contact that office ahead of time and ask whether it accepts recalled lithium-ion batteries. If it does not, contact your municipality for further guidance.”
