Rechargeable hand warmer recalls now cover OCOOPA, HotHands and Gobi Heat. Check the model number on the underside.

If you own a pair of rechargeable hand warmers that snap together with magnets, turn them over before they go in your cold-weather kit. Three federal recalls since July 30 cover about 1.58 million of them, and the model number printed on the underside is how you tell whether yours is one.

The three recalls

OCOOPA’s is the largest. CPSC recall 26659, published July 30, 2026, covers about 1.5 million OCOOPA rechargeable hand warmers, models UT3053, UT3056, ZLS-118, ZLS-118S, ZLS-118D, H01 and H01(PD). CPSC says the lithium-ion battery “can overheat and ignite.” The record lists 1,480 reports of overheating, 15 fires and 350 burn injuries, including the death of an 83-year-old consumer in San Diego in February 2026. They sold on Amazon, Walmart.com and OCOOPA’s own sites from September 2018 through May 2026, for $15 to $60.

Two more followed on October 1. HotHands rechargeable warmers, model H163650: about 77,000 units sold at Bass Pro Shops, Meijer, Target, The Home Depot and Amazon from July 2025 through August 2026, for $30 to $40. And Gobi Heat model UT3053: about 5,500 units sold on GobiHeat.com from October 2024 through August 2026. Neither of those records reports an injury.

Why the brand on the shell tells you little

The two October recalls trace back to the July one, and the companies say so themselves. Kobayashi’s recall notice states that HotHands rechargeable warmers “share the identical lithium-ion battery and electrical components” with the OCOOPA product, and that it is recalling them even though it has no reported incidents of its own. Gobi Heat’s recall page names OCOOPA Innovation Corp. as importer and manufacturer, and Gobi’s model number, UT3053, is one of the numbers on OCOOPA’s July list.

What is not recalled

HotHands air-activated packets, the disposable kind most people carry, are not part of this. Kobayashi’s notice says so in capital letters, and only the electric rechargeable unit with the white HotHands logo is covered.

A lookalike from a brand not named here is not covered by any of these three recalls, and no CPSC record we read says anything about it. If yours matches the description (two units, magnetic, USB-C charging, LED heat lights, silicone lanyard) and carries no model number listed above, ask the seller who made it.

What to do this week

1. Read the underside. Match the model number. HotHands also asks for the four-digit batch number, OCOOPA for the three-digit one.
2. Stop using it, and stop charging it. All three remedies start there.
3. File the claim. Each one asks you to write “RECALLED” on the warmer in permanent marker and send a photo. OCOOPA refunds through the claim page its CPSC record lists (ocoopa.com/pages/product-recalls), HotHands through the notice page above, and Gobi Heat offers a refund or store credit worth 120 percent. Kobayashi says not to throw the warmer out until your claim is complete.
4. Dispose of it properly. Not the trash, not curbside recycling, not the battery box at a hardware store. CPSC directs you to a municipal household hazardous waste center, and to call ahead. On the road, that means a phone call to the next town’s solid waste office before you drive over.
