Are Your Hand Warmers Safe After the OCOOPA Recall?

Do not buy a replacement yet. Turn over the hand warmer already in your bag or drawer and check the model number and three-digit batch on the underside. On July 30, 2026, CPSC recall 26-659 covered roughly 1.5 million OCOOPA rechargeable hand warmers after 1,480 overheating reports, 15 fires, 350 burn injuries, and one death. [1]

Check the unit you already own

This recall is model-specific, not brand-wide. The recalled models are ZLS-118, ZLS-118S, ZLS-118D, H01, H01(PD), UT3053, and UT3056. OCOOPA's recall page maps UT3053 to UT3 Lite and UT3056 to UT4 Young, so the printed model number on the unit matters more than the marketing name on the box. [1][2]

• ZLS-118
• ZLS-118S
• ZLS-118D
• H01
• H01(PD)
• UT3053
• UT3056

If the model number matches, stop using it, do not charge it again, and keep it out of the normal gear cycle. OCOOPA directs owners to email [email protected] for a full refund by gift card or original payment, then mark the device 'RECALLED,' photograph it with the model and batch number, and remove it from regular household disposal. If the model does not match, write down the exact model anyway and re-check CPSC before charging it for the season. [2]

Take the recalled unit to a municipal Household Hazardous Waste center. Do not put it in trash, curbside recycling, or a retail battery bin. The point is not just to get rid of a product; it is to get a lithium-ion device out of the places where it can be charged, crushed, or mixed back into normal household use. [2]

What to use for winter running instead

This is where review roundups can mislead you if you skip the label check. In the sources reviewed here, Wirecutter's 2026 budget pick was the Ocoopa UT3 Lite, which OCOOPA maps to recalled model UT3053, while GearJunkie's 2026 guide still gave OCOOPA's UT3 PRO a top rechargeable slot. The lesson is not that every OCOOPA product is off-limits; it is that a roundup cannot tell you what is actually sitting in your pocket, so the CPSC page still comes first. [2][3][4]

• Air-activated disposables are the lowest-risk default for winter runs. Wirecutter reported that HotHands stayed above 99F for about 5.5 hours at around 102F and fit in a glove, with bulk pricing around $0.75 per pair. [3]
• Resealable air-activated warmers are a good middle ground when you want more runtime without a battery. GearJunkie tested Ignik's version at about 10 hours, with about 127F in-pocket and 140F on the surface. [4]
• Sodium-acetate reusables are the compact option for shorter outings or warm-up use. GearJunkie reported about 30 to 60 minutes per activation and a 5 to 10 minute boiling reset for HotSnapZ. [4]
• A verified rechargeable is the fallback when you truly need long runtime or power-bank use. Before trusting one for a run, confirm the exact model against CPSC and OCOOPA, keep the device around 110F to 120F, use a cloth barrier, charge it in an open area, never leave it charging overnight, and stop using it if the enclosure swells or runs excessively hot.
