Quick answer: Kobayashi Consumer Products is recalling about 77,000 HotHands rechargeable hand warmers in the United States, plus about 72 sold in Canada, because their lithium-ion batteries and electrical components can overheat and ignite. The affected model is H163650. Consumers should stop using the warmers immediately and follow the company’s instructions for a full refund.
The U.S. Consumer Product Safety Commission announced the recall on October 1, 2026. No injuries or incidents were reported in the CPSC notice, but the agency describes the potential fire and burn hazard as serious.
Which HotHands hand warmers are recalled?
The recall covers HotHands-branded electric rechargeable hand warmers sold in pairs. The devices are white and orange, can connect magnetically, include a USB-C charging port and contain built-in lithium-ion batteries.
Look for model number H163650 on the underside of the warmer. A four-digit batch number is also printed on the device. The CPSC says only the electric rechargeable hand warmers with the white HotHands logo are part of this recall.
Where were the recalled hand warmers sold?
According to the CPSC, the recalled products were sold at Bass Pro Shops, Meijer, Target, The Home Depot and other stores nationwide, as well as online at Amazon.com. Sales ran from July 2025 through August 2026, with prices generally between $30 and $40.
What is the hazard?
The CPSC says the lithium-ion battery and electrical components can overheat and ignite, creating a fire and burn risk. Even though the recall notice lists no reported incidents or injuries, consumers should not continue using a recalled device while waiting to see whether it becomes hot or behaves unusually.
How to get a refund
- Stop using the recalled HotHands hand warmers.

Do not put the recalled battery in household trash
The CPSC specifically warns consumers not to throw the recalled lithium-ion device into ordinary household trash, curbside recycling or common used-battery collection boxes. Recalled lithium-ion batteries require different handling because they can present a higher fire risk.
Consumers should contact a municipal household hazardous-waste facility first to confirm whether it accepts recalled lithium-ion devices. If it does not, ask the local municipality for the correct disposal route.
How to identify this recall correctly
Several rechargeable hand-warmer products have been recalled, so model identification matters. This notice is specifically for HotHands model H163650 distributed by Kobayashi Consumer Products. Do not rely only on the fact that a warmer is rechargeable or orange and white; verify the model information printed on the device.
