UL Solutions has issued a safety notice warning that Model A23 hand warmers sold on Amazon.com feature an unauthorized UL Certification Mark. Because these devices have not undergone required safety evaluations, the manufacturer is urging users to stop using them immediately.
Why it matters
The presence of an unauthorized certification mark means these hand warmers have not been tested for safety standards, which is particularly critical for devices containing lithium-ion batteries. Using uncertified electronics poses unknown risks to the user and their home environment.
The notice, identified as 26PN-0213, covers Model A23 hand warmers produced by Shenzhen Little Black Technology Electronics Co., Ltd. These items were distributed through Amazon.com.
The players
UL Solutions
An independent global safety science company based in Northbrook, Illinois, that has spent 40 years testing battery technology and operating in 110 countries.
Shenzhen Little Black Technology Electronics Co., Ltd.
The manufacturer of the Model A23 hand warmer involved in the safety certification notice.
The details
The safety risk arises because unauthorized certification marks were applied to both the hand warmers and their packaging, falsely suggesting they had been evaluated by UL Solutions. Because the device uses lithium-ion battery technology, it requires rigorous testing to ensure it meets established safety benchmarks. Users should not attempt to repair or modify these units and must follow local lithium-ion battery disposal protocols to safely discard them.

The Home Front
This notice highlights the ongoing challenge of verifying product safety standards for electronics sold on large e-commerce platforms. It underscores why certification marks remain a primary indicator for homeowners assessing the safety of battery-operated goods.
If you own a Model A23 hand warmer, remove it from use immediately and check your purchase history on Amazon to verify the model. Ensure you follow local waste management guidelines for lithium-ion battery disposal rather than placing the unit in regular household trash.
The takeaway
Unauthorized certification marks are a significant warning sign that a product may not meet basic safety requirements for battery operation. If you possess a Model A23 hand warmer, prioritize disposing of the unit safely according to your local lithium-ion recycling regulations.
