Before you charge your hand warmers for a chilly morning, flip them over. HotHands rechargeable hand warmers with model number H163650 are being recalled, and owners should stop using them immediately.
This is worth checking even if yours have worked perfectly. The October 1, 2026 recall covers about 77,000 units sold in the U.S. because the battery and electrical components can overheat and catch fire. HotHands says there have been no reported incidents or injuries associated with this battery issue in its product.
Check the model, not just the HotHands name
The affected warmers are white and orange, come in a pair that joins magnetically, and have a white HotHands logo. Look underneath for H163650 and the batch number.
They were sold from July 2025 through August 2026 at Target, The Home Depot, Bass Pro Shops, Meijer, Amazon and other retailers.
There’s an important distinction here: HotHands says its air-activated hand warmers are not included. This notice is about the specified rechargeable model, so check the actual device before assuming every HotHands product in your winter stash is affected.
Get the refund started before you get rid of them
Start at the official recall page and choose “Submit Recall Claim.” The process gives you a claim number and instructions for a refund.
You’ll be asked to write “Recalled” and that claim number on the product in permanent marker, then send photos showing the markings, model number and four-digit batch number. The manufacturer also requests a receipt photo if you have one.
Keep the product until you’ve completed the claim. HotHands specifically says not to dispose of it first.
These cannot go in the kitchen trash
After the claim is complete, follow the recall’s hazardous-waste disposal instructions. Do not put the warmers in regular garbage, curbside recycling or the used-battery collection boxes at stores.
Call your municipal household hazardous-waste collection center before taking them in and ask whether it accepts recalled lithium-ion devices. If it doesn’t, contact your municipality for the appropriate next step.
