One model number covers the entire recall: H163650, printed on the underside of the HotHands Rechargeable Hand Warmers that Kobayashi Consumer Products, LLC of Dalton, Georgia sold in the United States between July 2025 and August 2026. The U.S. Consumer Product Safety Commission puts the count at about 77,000 units, with roughly 72 more sold in Canada. Every one of them is a white warmer with orange accents, sold as a two-pack.
The question of which warmers are involved has a short answer, but the surrounding recalls make it easy to get wrong, because two other rechargeable hand-warmer recalls landed within weeks of it and one of them shares a model number with a different brand.
Model H163650 and what it looks like
According to the CPSC notice for recall number 27-011, announced October 1, 2026, the product is named “HotHands Rechargeable Hand Warmers.” Each pack holds two magnetic warmers that can snap together, with a USB-C charging port, adjustable heat settings, LED indicator lights and a silicone lanyard. The pair retailed for between $30 and $40 at Bass Pro Shops, Meijer, Target, The Home Depot and Amazon.com, along with other stores nationwide. The commission’s notice lists no separate SKUs or UPC codes, so the printed model number is the test.
Kobayashi’s own recall notice on hothands.com repeats that identification and adds a boundary that matters for anyone who bought HotHands in a store aisle: the recall excludes the air-activated HotHands warmers, the disposable packets that heat through a chemical reaction. Only the rechargeable model is affected, and only units sold in the July 2025 to August 2026 window.
Lithium-ion cells in a pocket-size shell
The hazard is stated in the CPSC’s words: the lithium-ion battery and electrical components “can overheat and ignite, posing a risk of serious injury from fire and burn hazards.” The notice places the fault in the battery and electrical components, and it follows the pattern the commission describes in its own guidance on battery standards, where overheating, fire and thermal burns are listed as potential hazards that occur “while the product is in use, in storage, and during battery charging.”
A hand warmer sits in about the worst place for that failure. It is held against skin or tucked inside a glove or a coat pocket, and it is built to run warm on purpose, so a cell that runs away has little distance to travel before it reaches fabric or a hand.
The CPSC page records no incident reports for the HotHands model. That sets it apart from the OCOOPA recall in July, which came with a death and hundreds of burns.
Gobi Heat and OCOOPA, the two lookalike recalls
The same day as the Kobayashi announcement, the commission published recall 27-009 for Gobi Heat rechargeable hand warmers: about 5,500 units of model UT3053, plus 47 in Canada, sold through GobiHeat.com from October 2024 through August 2026 at $20 to $40. The wording of the hazard is identical to the HotHands notice, and the wording is where the resemblance ends. Gobi Heat is a separate company, a separate product and a separate remedy process, so a HotHands owner has nothing to do with it unless the warmer says Gobi Heat.
The second recall is far larger. On July 30, 2026, the CPSC announced that OCOOPA Direct was recalling about 1.5 million rechargeable hand warmers, sold between September 2018 and May 2026 on Amazon, Walmart.com and OCOOPA’s own sites for $15 to $60. The commission counted 1,480 reports of overheating, 15 fires and 350 burn injuries, plus one death: an 83-year-old in San Jose, California, in February 2026.
The OCOOPA notice lists seven model numbers: UT3053, UT3056, ZLS-118, ZLS-118S, ZLS-118D, H01 and H01(PD). UT3053 is the same number the commission gives for the Gobi Heat product, which means a model number alone does not settle whose recall a warmer belongs to. For HotHands buyers the cleanest check remains the combination the notice spells out: the HotHands name, the model number H163650 on the bottom, and a purchase between July 2025 and August 2026.
Counting the 77,000
The 77,000 figure is a United States count and a rounded one, taken from the CPSC notice itself. It describes units sold at retail and online, not people affected, and since the warmers were sold in two-packs, the number of households holding one may be well below it. The commission did not break the total down by retailer or by month.
What the Kobayashi notice does set out in detail is the remedy: a full refund, claimed by registering on the recall website, marking the device and photographing it with the model and batch numbers visible before it goes to a household hazardous waste facility. The commission’s own page for 27-011, last read on October 7, 2026, still carries the same unit count and the same absence of reported incidents.
