Amazon Hand Warmer Burn Lawsuit Alleges Defective Product Caused Permanent Disfigurement

Lawsuit claims a defective hand warmer caused severe third-degree burns to a woman’s leg after only 15 minutes of use.

A Pennsylvania woman has filed a lawsuit alleging Amazon sold a portable hand warmer without adequate safeguards to prevent overheating, placing consumers at risk of serious burns even when the device was operated on its lowest setting.

The complaint (PDF) was brought by Elisa Vagnozzi in the Court of Common Pleas of Allegheny County, Pennsylvania on September 18, naming Amazon.com Inc., Amazon.com Services LLC and three unidentified individuals as defendants. The case was removed to the U.S. District Court for the Western District of Pennsylvania on November 2.

Vagnozzi claims the hand warmer lacked adequate temperature controls, automatic shutoff features and warnings about the risk of serious burns.

Portable Heating Device Risks

Hand warmers are portable heating devices that allow consumers to stay warm in cold conditions. However, defects in their design or manufacturing can create overheating hazards, potentially causing fires, severe burns or battery thermal runaway.

In recent months, a number of product liability lawsuits allege battery-powered warming devices have caused serious injuries because of inadequate safety protections. Claims in numerous heated insole injury lawsuits allege inadequate temperature controls and other safety deficiencies allowed the products to become dangerously hot during normal use.

Several of these complaints also name Amazon as a defendant, arguing the online retailer bears responsibility for distributing and selling allegedly defective warming products that exposed users to preventable burn injuries.

Amazon Hand Warmer Burn Allegations

According to the complaint, Vagnozzi purchased a portable hand warmer through Amazon on November 23, 2024. She claims she used the product only once before the incident, briefly operating it on its lowest setting, and did not substantially alter the device after purchasing it.

On January 5, 2025, Vagnozzi was playing board games with her son while sitting with her legs crossed. The lawsuit indicates she positioned one of the hand warmers between her left foot and right leg, with the device operating on its lowest heat setting.

After approximately 15 minutes, Vagnozzi allegedly suffered severe third-degree burns to her lower left extremity.

The complaint indicates Vagnozzi’s injuries required surgical debridement to remove damaged tissue, followed by an autograft procedure using healthy skin taken from her left calf.

“As a direct, proximate and legal result of the defective product, Plaintiff sustained life-altering and severe third-degree burns to her lower left extremity requiring surgeries and resulting in permanent disfigurement.”

— Elisa Vagnozzi v. Amazon.com Inc. et al.

Vagnozzi argues the hand warmer could reach dangerously high temperatures during normal use, despite the availability of safer designs incorporating automatic shutoff features and maximum temperature controls.

The lawsuit raises allegations of strict product liability and negligence against all defendants. It seeks compensation for medical expenses, pain and suffering, permanent disfigurement, lost income and other damages.
