Only the rechargeable units are covered
Kobayashi recalled about 77,000 HotHands rechargeable hand warmers in the United States October 1, with about 72 more sold in Canada, over fire and burn risks. CPSC says no incidents were reported. The recall is for specified electric rechargeable warmers, not the familiar disposable HotHands packs.
The covered model is H163650: white-and-orange units sold in pairs that can attach magnetically, with USB-C charging, LED indicators and a silicone lanyard. The model and batch numbers appear on the underside. Use those identifiers and the CPSC photos rather than the editorial illustration to match a purchase.
Get the refund evidence before safe disposal
The full-refund process requires stopping use, contacting the firm through the recall route, obtaining a claim number, marking the product and submitting photos showing the marking, model and four-digit batch number. Follow the actual claim instructions before disposal so required evidence is not lost.
CPSC explicitly warns against putting this recalled lithium-ion device in ordinary trash, curbside recycling or retail battery boxes. Contact the local hazardous-waste service first to check acceptance of recalled batteries. The units sold July 2025 through August 2026 for $30 to $40. A refund remedy does not remove the separate disposal hazard or make ordinary battery-recycling instructions suitable.
