Health Canada Recalls Two Rechargeable Hand Warmer Lines, 119 Canadian Units Headed for Hazardous Waste Disposal

Most owners won't have the packaging. That's fine. The identifier you need is on the warmer itself.

HotHands: model H163650 on the underside

Health Canada says the HotHands model and batch numbers are printed on the underside of the warmer, with the white HotHands logo on top. The recalled units are white with orange, sold in packs of two that join magnetically, with a USB-C charging port, adjustable heat, LED indicators and a silicone lanyard. If the underside reads H163650, it's covered. Note the batch number as well, because the refund claim asks for it.

This recall covers only the rechargeable model. Disposable air-activated HotHands packets aren't part of it.

Gobi Heat: UT3053 on the underside

The Canadian notice lists the Gobi pair by SKU and UPC but doesn't say where on the warmer the number is printed. The U.S. Consumer Product Safety Commission's Gobi Heat notice answers that: "Gobi Heat" is printed on top of the warmer and model number UT3053 on the underside. The warmers are black with grey accents, sold in magnetically joined pairs with a charging cable, LED indicator lights and a silicone lanyard.

Why UT3053 alone isn't enough

This is the detail that connects the October recalls to the September one. Health Canada names Shenzhen Street Cat Technology Co., Ltd. as the Gobi warmer's manufacturer. The same company appears as the importer, doing business as OCOOPA Direct, in the OCOOPA recall. UT3053 is also one of the seven OCOOPA models recalled in September, and OCOOPA's own recall page lists it as the UT3 Lite.

None of the notices says the two products are identical, so don't read more into it than that. The practical point is narrower: a warmer stamped UT3053 on the underside could fall under either recall, and the brand printed on top decides which one. A Gobi Heat logo means you contact Gobi Heat. An OCOOPA warmer means the September recall, RA-82578, which also covers models UT3056, ZLS-118, ZLS-118S, ZLS-118D, H01 and H01(PD).

The Canadian numbers are small, and both companies report zero incidents. That's reassuring, and it's also the wrong reason to leave a recalled warmer in a drawer.

The reason is the sheer variety of places these things end up. A rechargeable hand warmer is built to be portable and forgettable. It rides in a ski jacket, sits in a car console through a cold snap, or gets tossed in a bin of winter accessories in the garage. That storage pattern is what keeps the 119 figure from being trivial: the people who own these may not know it, and the device may be sitting next to something flammable when it does fail.

What the same failure has produced at scale

The OCOOPA recall shows what overheating looks like across a much larger installed base. The U.S. Consumer Product Safety Commission's OCOOPA notice covered about 1.5 million units and cited 1,480 reports of overheating, 15 fires and 350 burn injuries in the United States, including the death of an 83-year-old consumer in California in February 2026.

Those are American numbers, and they describe a different brand. In Canada, the Health Canada OCOOPA notice covered 23,000 units sold from September 2025 to May 2026, with no Canadian incidents or injuries reported as of August 27, 2026. Nobody should treat the U.S. injury count as a forecast for HotHands or Gobi owners. What it does show is why both October notices say "immediately" rather than "monitor": this product category has already shown it can fail badly.

The same logic applies to other lithium-ion devices people carry. Our coverage of the 30,000 MagSafe power banks recalled at Winners and HomeSense followed the same pattern of a small, portable battery stored all over the house.
