January 20, 2026 – Reports have emerged concerning Renpho NA-H1222D heating pads, detailing incidents of electrical malfunctions and cord failures, including popping sounds and severed cords. Consumers are advised to exercise caution and review the safety information provided.
Product Details
Incident Overview
On December 21, 2025, a consumer reported incidents involving two Renpho NA-H1222D heating pads purchased from Amazon. The first heating pad experienced a cord coming out and apart after very little use. The second heating pad made a loud popping sound, followed by the cord becoming severed not far from the control unit.
The consumer also reported significant difficulty in contacting the manufacturer, joicom Corporation. Attempts to reach the company via phone reportedly led to instructions to email, which in turn resulted in missed return calls and an “endless loop” of communication challenges.
Safety Concerns
The reported incidents with the Renpho NA-H1222D heating pads present several serious safety concerns for consumers:
- Immediate Dangers: The primary immediate dangers include electrical shock and burns. A cord coming apart or becoming severed, especially with a popping sound, indicates a potential short circuit or arcing, which can expose live wires. This poses a direct risk of electric shock upon contact. Furthermore, uncontrolled electrical events can generate intense heat, leading to severe burns to the user.
- Fire Hazard: Electrical malfunctions, short circuits, and overheating due to damaged or severed cords are significant fire hazards. A heating pad operating with compromised wiring can ignite nearby flammable materials such as bedding, clothing, or furniture, potentially leading to widespread property damage or even structural fires.
- Long-Term Risks: Even if an initial incident does not result in immediate injury, continued use of a faulty heating pad can lead to recurring electrical issues that may escalate in severity over time. Unseen internal damage could worsen, increasing the risk of future electrical shocks, burns, or fires.
- Who Might Be Affected: Anyone using the heating pad is at risk. This includes individuals using it for therapeutic purposes, who may be less mobile or attentive to immediate signs of malfunction. The risk of fire also extends to anyone within the vicinity of the product, and to the entire household or property.
- Property Damage Potential: A fire originating from an electrical fault in a heating pad can cause significant damage to personal property, including bedding, furniture, and the structure of the home. Damage could also extend to electrical outlets and the household’s electrical system.
What Consumers Should Do
Consumers who own a Renpho NA-H1222D heating pad should take the following precautions:
- Stop Use Immediately: If you own a Renpho NA-H1222D heating pad and observe any signs of damage, unusual sounds (like popping), smells (like burning plastic), or malfunctions, unplug the device immediately and cease all use.
- Inspect Your Product: Carefully examine the heating pad, particularly the power cord and control unit, for any visible signs of fraying, cuts, exposed wires, loose connections, or discoloration. Even if your unit appears fine, remain vigilant for any changes in performance.
- Do Not Attempt Repairs: Do not attempt to repair damaged cords or electrical components yourself, as this can be extremely dangerous and may void any potential warranties or recourse.
- Report Incidents: If you have experienced a similar incident or have concerns about your Renpho NA-H1222D heating pad, report it to the U.S. Consumer Product Safety Commission (CPSC) at SaferProducts.gov.
- Contact Retailer: Reach out to Amazon to inquire about return, refund, or replacement options.
- Contact Manufacturer: Document all attempts to contact joicom Corporation regarding product defects or safety concerns.
