August 24, 2026 — A DENGWENQIANG OFS-391 charging block purchased from Amazon.com reportedly overheated to the point of melting and emitting a burning plastic smell. This incident, reported on August 4, 2026, is not isolated, with multiple other customers experiencing similar severe overheating issues and leaving one-star reviews for the product.
Product Details
Incident Overview
The incident, reported on August 4, 2026, involved a consumer who purchased a DENGWENQIANG OFS-391 charging block from Amazon.com. The product, designed to plug directly into an electrical wall outlet, reportedly overheated severely during use. This extreme overheating caused the charging block itself to melt and emit a distinct, concerning burning plastic smell. The consumer promptly unplugged the device upon noticing the issue. This appears to be a systemic problem, as the report indicates that “multiple other customers who have reported the same issue and have left one-star Amazon reviews,” suggesting a widespread defect rather than an isolated incident. The specific date of purchase is not detailed, but the incident occurred subsequent to purchase.
Safety Concerns
The severe overheating and melting of the DENGWENQIANG OFS-391 charging block present significant safety risks to consumers and their property:
- Immediate Dangers: The primary immediate danger is the risk of fire and electrical shock. An overheating electrical device, particularly one that melts, can ignite nearby flammable materials such as curtains, furniture, or carpets, leading to significant property damage or even structural fires. There is also a risk of burns to individuals handling the device, especially if they attempt to unplug it while it’s actively overheating. The burning plastic smell indicates off-gassing, which can release toxic fumes into the air, posing respiratory hazards.
- Long-Term Risks: Repeated overheating and melting of electrical devices can damage electrical outlets and the home’s electrical wiring system, leading to long-term safety hazards and expensive repairs. Exposure to burning plastic fumes over time could have health implications, though the immediate concern is acute exposure.
- Who Might Be Affected: Anyone using the DENGWENQIANG OFS-391 charging block is potentially at risk. This includes individuals, families, and even businesses that might use these charging blocks for various electronic devices. Children or individuals unaware of the risks might unknowingly continue to use a faulty device or be exposed to its hazards.
- Property Damage Potential: The most significant property damage potential is a house fire. An overheated and melting charging block can easily ignite combustibles, causing extensive damage to homes, personal belongings, and potentially leading to total loss. Even without a full-blown fire, melting plastic can damage the electrical outlet, wall, and nearby surfaces.
What Consumers Should Do
Given the severe nature of the reported incidents, consumers who own a DENGWENQIANG OFS-391 charging block should take immediate action:
- Immediately Stop Use: If you own a DENGWENQIANG OFS-391 charging block, or any similar DENGWENQIANG charging product, immediately stop using it. Unplug it from the electrical outlet. If the device is hot, exercise extreme caution or avoid direct contact until it has cooled.
- Identify the Product: Check your charging blocks for the brand “DENGWENQIANG” and model number “OFS-391.”
- Do Not Discard or Modify: Do not attempt to repair the device or discard it. Retain the product as it may be crucial evidence if further investigation or recall action is pursued.
- Report the Incident: If you have experienced overheating or melting with this product, report the incident to the U.S. Consumer Product Safety Commission (CPSC) at www.SaferProducts.gov. This helps the CPSC gather data and potentially initiate a recall.
- Contact the Retailer/Manufacturer: Reach out to Amazon.com or DENGWENQIANG to report your experience and inquire about potential refunds or remedies.
- Prevention: Always monitor charging devices. If you notice any unusual heat, burning smells, smoke, or visible deformation, immediately unplug the device and discontinue use. Never leave charging devices unattended, especially overnight or when away from home. Ensure proper ventilation around charging blocks.
