February 24, 2026 — A recent incident report details a potentially life-threatening situation involving a CyberPower multi-plug adapter in a 5th wheel RV. A consumer reported being woken by an electrical smell in the middle of the night, only to discover a spring from an unknown source had become lodged between the prongs of a plug inserted into the CyberPower unit, leading to burnt wiring and fumes. This incident highlights critical safety concerns regarding multi-plug adapters and the importance of proper usage.
Product Details
Incident Overview
On January 2, 2026, a consumer reported a serious incident involving a CyberPower multi-plug adapter. The device, equipped with six outlets, a USB port, and a Type-C port, was in use in the consumer’s 5th wheel RV. In the middle of the night, the consumer’s fiancé was awakened by a distinct electrical burning smell. Upon investigation, the source was traced to the CyberPower multi-plug.
A critical discovery was made: a spring, which the consumer stated came out of the multi-plug, had become jammed between the prongs of a connected plug. This created an electrical short, causing wiring to burn and releasing harmful fumes. While the occupants fortunately suffered no physical injuries, the incident resulted in damage to both the outlet and the plug. The consumer emphasized the gravity of the situation, noting that had they not woken up, the outcome could have been life-threatening due to the potential for a full-scale electrical fire. The duration for which they had been inhaling the burnt wire fumes remains unknown.
Safety Concerns
This incident brings to light several serious safety concerns associated with multi-plug adapters and electrical safety, particularly in mobile living environments like RVs:
- Immediate Dangers: The primary and most immediate danger is the risk of an electrical fire. A short circuit, caused by a foreign object or internal malfunction, can quickly generate extreme heat, igniting surrounding materials. The burnt wiring and fumes indicate a high-risk situation that could have escalated rapidly.
- Smoke Inhalation: The report details “burnt wire fumes,” which can be toxic. Inhaling such fumes, especially in an enclosed space like an RV, can lead to respiratory distress, poisoning, and long-term health issues. In severe cases, smoke inhalation can be fatal.
- Property Damage: The incident already caused damage to the outlet and the plug. An uncontained electrical fire could lead to extensive damage or complete destruction of the RV and its contents.
- Who Might Be Affected: Anyone in the vicinity of the faulty product is at risk, particularly those sleeping nearby who might not detect the danger until it’s too late. Children and pets are especially vulnerable due to their smaller size and potential inability to react quickly.
- Foreign Object Intrusion: While the origin of the spring is disputed by the manufacturer, the presence of any foreign object creating an electrical short poses a significant hazard. This highlights the importance of regularly inspecting electrical connections and ensuring plugs are fully seated without any obstructions.
What Consumers Should Do
Consumers using multi-plug adapters, especially in RVs or non-standard electrical setups, should take the following precautions:
- Immediate Action for Suspicious Odors: If you detect any electrical burning smell, unplug all devices immediately if safe to do so. Locate the source of the smell and investigate carefully. If a device is hot or sparking, do not touch it; turn off power at the circuit breaker if possible and evacuate the area.
- Inspect Your Multi-Plug Adapters: Regularly check your multi-plug adapters and surge protectors for any signs of damage, such as discoloration, melted plastic, loose parts, or strange odors. Ensure all plugs are fully inserted and that there are no gaps or foreign objects near the prongs.
- Understand Product Limitations: Be aware of the manufacturer’s usage instructions, especially regarding environments. Many electrical products are designed for standard grounded wall outlets and may not be suitable for RVs, generators, or ungrounded power sources.
- Proper Use and Placement: Avoid overloading multi-plugs. Only plug in devices that draw appropriate power. Do not daisy-chain multi-plugs or use extension cords in conjunction with them unnecessarily. Ensure proper ventilation around adapters and do not place them near flammable materials.
- Report Incidents: If you experience a similar incident, immediately report it to the manufacturer and the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report helps identify safety trends and potentially prevent future incidents.
Manufacturer’s Response
On February 9, 2026, CYBERPOWER SYSTEMS USA INC provided a response, stating their investigation has been limited due to the customer not directly contacting them. CyberPower stated they could not substantiate the safety claims based on the brief CPSC report and without evaluating the alleged damaged unit or receiving further information.
Regarding the “spring” described by the consumer, CyberPower’s response noted that their products, including the presumed model P6WSUC, do not contain any springs or spring-like components. They posited that the spring must have originated externally and was likely the cause of the incident.
CyberPower also raised concerns about the product’s use in a 5th wheel RV. They referenced their user manuals, which specify plugging surge protectors into “standard grounded wall outlets” directly connected to utility power. They contended that a 5th wheel’s electrical connections (ungrounded power, RV hookups, or generators) do not qualify as “standard grounded wall outlets.” Furthermore, CyberPower highlighted user manual warnings against using the product if “exposed conductors” are present or if “properly grounded outlets are not available.” They also noted the manual’s instruction not to install the device if there is less than 10 meters (30 feet) of wire between the electrical outlet and service panel, suggesting that 5th wheels, typically shorter than 30 feet, would violate these installation instructions, constituting improper use.
