June 5, 2026 — A recent incident report details a significant safety concern involving an EcoFlow DELTA Pro portable power station, which reportedly experienced a thermal event and emitted fire and smoke while connected to a standard household AC wall outlet for charging. The incident highlights potential fire hazards associated with the device’s internal charging system during normal operation.
Product Details
Incident Overview
On May 18, 2026, an EcoFlow DELTA Pro power station, identified by its model number EFD500, reportedly overheated and ignited internally while being charged using its factory-provided X-Stream AC charging system. The unit was connected to a standard household AC wall outlet, operating under normal intended conditions. According to the incident report, the device had not been physically damaged, modified, or exposed to water prior to the event. The thermal event, which led to fire and smoke emission, appears to have originated from the charging/inverter section of the power station while it was under AC input load. This incident created an immediate and significant fire hazard, necessitating prompt intervention to prevent the spread of flames. The affected unit has since been preserved for inspection and has not been powered on or used further.
Safety Concerns
This incident raises serious safety concerns for consumers owning or considering the EcoFlow DELTA Pro portable power station.
- Immediate Dangers: The primary and most immediate danger is the risk of fire and smoke. A thermal event leading to ignition can quickly escalate, causing significant property damage to homes or surrounding areas where the unit is being charged. Such an event also poses a direct threat of personal injury, including burns, smoke inhalation, and other fire-related harm, to anyone in the vicinity of the device. The incident explicitly states that immediate intervention was required, underscoring the severity of the fire hazard.
- Property Damage Potential: An internal ignition event within an electrical device carries a high risk of property damage, potentially leading to the destruction of furniture, electronics, and structural components of a building. The reported origin from the charging/inverter section suggests a critical failure within the unit’s power conversion system, which could lead to uncontrolled thermal runaway.
- Who Might Be Affected: Owners of the EcoFlow DELTA Pro (model EFD500) who use the device for AC charging are potentially at risk. This includes individuals who rely on the power station for home backup, outdoor activities, or as a primary power source. Given the widespread use of such portable power stations, a broad consumer base could be impacted.
- Long-Term Risks: While the immediate danger is fire, the underlying cause of the thermal event (e.g., component failure, design flaw, manufacturing defect) could indicate a systemic issue with certain batches or the overall design of the product, presenting a persistent risk to consumers until thoroughly investigated and addressed.
What Consumers Should Do
If you own an EcoFlow DELTA Pro (model EFD500) or a similar EcoFlow portable power station, it is crucial to take the following steps to ensure your safety:
- Immediate Steps: If you observe any signs of overheating, smoke, unusual odors, or abnormal noise from your power station, immediately and safely disconnect it from its power source if possible, and move it to a safe, non-combustible area away from flammable materials. Do not attempt to use the device again. If fire or significant smoke is present, evacuate the area and contact emergency services.
- How to Check if You Own the Affected Product: Verify the model number of your EcoFlow power station, typically found on a label on the unit itself or in its accompanying documentation. This incident specifically refers to the EcoFlow DELTA Pro (model EFD500).
- Prevention Measures: Until further information or guidance from the manufacturer is available, consider exercising extreme caution when charging your EcoFlow DELTA Pro. Always charge the unit in an open, well-ventilated area, away from combustible materials. Never leave the unit unattended while charging, and ensure it is placed on a non-flammable surface. Avoid charging the unit overnight or when you are not present to monitor it.
- Reporting Procedures: If you have experienced a similar incident or have concerns about your EcoFlow DELTA Pro, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at www.SaferProducts.gov. This helps the CPSC gather vital data for potential investigations and recalls.
