If your rechargeable hand warmer is an Ocoopa, a HotHands or a Gobi Heat, stop using it until you have checked the model number. The U.S. Consumer Product Safety Commission has posted a hand warmer recall for each of the three brands because the lithium-ion batteries can overheat and ignite. This guide explains which units are covered, how to claim a refund and how to get rid of the battery safely.
Hand warmer recall at a glance
The three notices differ a lot in size, and only one reports injuries. Here are the numbers straight from the CPSC pages.
| Brand | Recall date | U.S. units | Price range | Reported problems |
|---|---|---|---|---|
| Ocoopa | July 30, 2026 | About 1.5 million | $15 to $60 | 1,480 overheating reports, 15 fires, 350 burn injuries, one death |
| HotHands (Kobayashi) | Oct. 1, 2026 | About 77,000 | $30 to $40 | None reported |
| Gobi Heat | Oct. 1, 2026 | About 5,500 | $20 to $40 | None reported |
Hand warmer recall: which brands and models are affected
Ocoopa Direct recalled about 1.5 million warmers sold from September 2018 through May 2026 on Amazon.com, Ocoopa.com, Ocoopa.net and Walmart.com. The company has received 1,480 reports of overheating, including 15 fires and 350 burn injuries, and one death was reported: an 83-year-old consumer in San José, California, in February 2026. The covered models are UT3053, UT3056, ZLS-118, ZLS-118S, ZLS-118D, H01 and H01(PD.).
The HotHands recall covers model H163650, a white-and-orange two-pack with USB-C charging, sold from July 2025 through August 2026 at Bass Pro Shops, Meijer, Target, The Home Depot, other retailers and Amazon.com. Only units with the white HotHands logo are included. The Gobi Heat recall covers black warmers with gray accents, sold in two-packs on GobiHeat.com from October 2024 through August 2026.
How to check your model number
On Ocoopa warmers, the model and a three-digit batch number are printed on the underside. HotHands units carry a model and a four-digit batch number, and the Gobi Heat model number is printed on the underside as well. One detail is worth noticing: UT3053 appears in both the Ocoopa and the Gobi Heat notices, so go by the brand name on the warmer and where you bought it, and contact the company if you cannot tell.
Check the date too. The Ocoopa hand warmer recall covers units sold over nearly eight years, so an older warmer from a past winter can still be on the list. The HotHands and Gobi Heat notices cover sales from the last year or two.
What to do if your hand warmer recall applies to you
- Stop using the warmer and unplug it from any charger.
- Go to the company’s recall page to start a claim. Ocoopa offers a refund as a gift card or to the original payment method, and Gobi Heat offers a refund or store credit worth the purchase price plus 20%. HotHands offers a full refund.
- Write “Recalled” on the warmer in permanent marker, then upload a photo showing the marking, the model number and the batch number.
- Keep the warmer somewhere safe, away from anything flammable, until you have disposal instructions for your area.
How to dispose of a recalled battery
Do not put a recalled warmer in the household trash or regular recycling, and do not drop it in a retail battery collection box. The CPSC notice says to follow local and state hazardous waste rules, and to call your household hazardous waste center first to confirm it accepts damaged lithium-ion batteries.

Before you buy a replacement after a hand warmer recall
The CPSC lists every notice on its recalls page, and a quick search for the brand and model takes a minute. A notice with no reported injuries, as with HotHands and Gobi Heat, still tells owners to stop using the product. If cold-weather costs are on your mind, our winter heating costs guide covers bigger savings than a pocket warmer will.
Editor’s take
The Ocoopa figures are the ones to remember: 350 burn injuries is a pattern, not a one-off. The two October recalls show the same battery risk reaching better-known retail brands before any injuries were reported, which is the best argument for checking a notice rather than waiting for a problem. Any lithium-ion gadget kept in a pocket or glove deserves the same check, and every hand warmer recall is worth a minute of reading.
