Product Details
Product: EcoFlow EFD310
Incident Overview
On August 21, 2026, an EcoFlow Delta Max 2000 battery, identified as model EFD310, experienced a catastrophic failure within a consumer’s bedroom. According to the incident report, a fire originated inside the battery. The battery then exploded, causing a large fire that spread battery shrapnel, toxic smoke/soot, and flames around the room.
At the time of the fire, the battery was not plugged into the wall directly, not charging any appliances, and not being used by anyone.
There were no physical injuries that happened. However, while extinguishing the fire, the two house members present both inhaled the toxic smoke for thirty minutes and may suffer from respiratory issues. Their conditions will continue to be monitored.
Safety Concerns
This incident with the EcoFlow Delta Max 2000 battery raises several critical safety concerns:
- Immediate Dangers: The explosion and subsequent fire present extreme immediate hazards. The spread of flames can quickly engulf a room or home, posing a severe risk to life and property. The spread of battery shrapnel acts as a projectile hazard, capable of causing traumatic injuries.
- Toxic Smoke/Soot Exposure: The smoke produced by battery fires, especially lithium-ion batteries, is highly toxic, containing various hazardous chemicals and particulate matter. Inhaling this smoke, even for a relatively short duration, can lead to respiratory issues. The two house members in this incident inhaled toxic smoke for thirty minutes and may suffer from respiratory issues, with their conditions continuing to be monitored.
- Unpredictable Failure: The fact that the battery exploded while not in use, not charging, and not connected to a power source is particularly alarming. This suggests a potential for spontaneous thermal runaway or internal short-circuiting that could occur at any time, without warning, and irrespective of user interaction.
- Property Damage Potential: Such an incident inevitably leads to extensive property damage from fire, smoke, and soot, potentially rendering affected areas uninhabitable and requiring costly remediation.
- Who Might Be Affected: Consumers who own or are in proximity to EcoFlow Delta Max 2000 units or similar high-capacity portable power stations could be at risk. First responders called to such incidents are also at risk of smoke inhalation and exposure to hazardous materials.
What Consumers Should Do
If you own an EcoFlow Delta Max 2000 (model EFD310) or a similar portable power station, please consider the following actionable advice:
- Identify Your Product: Check the model number on your EcoFlow portable power station to determine if it is an EFD310 (EcoFlow Delta Max 2000).
- Immediate Fire Safety: In the event of a fire involving a portable power station, prioritize your safety. Evacuate the area immediately and call emergency services (911 in the U.S.). Do not attempt to extinguish a large battery fire yourself unless you have appropriate training and equipment, as toxic fumes and reignition are significant risks.
- Monitor and Store Safely: While this incident occurred when the unit was not in use, generally, avoid leaving large battery units unattended, especially while charging. Store them in cool, dry, well-ventilated areas away from flammable materials and out of direct sunlight.
- Report Incidents: If you experience any overheating, swelling, unusual odors, or other signs of malfunction with your EcoFlow Delta Max 2000 or any other consumer product, stop using it immediately. Report the incident to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. Your report helps identify dangerous products and prevent future harm.
