Power Station Safety — 10 Things You Should Never Do

Portable power stations are remarkably safe compared to gas generators, but they're not indestructible. Lithium batteries store a lot of energy in a small space, and mishandling them can lead to damage, reduced lifespan, or — in rare cases — fire.

Here are 10 things you should never do with your portable power station.

1. Never Store at 0% or 100% Charge

Lithium batteries degrade fastest at extreme charge levels. Storing a power station at 0% for months can cause permanent damage (battery voltage drops too low to recharge). Storing at 100% accelerates capacity loss. Store at 50–80% for best lifespan.

2. Never Cover the Vents During Operation

Power stations generate heat during charging and discharging. Blocking the ventilation fans or intake grills can cause thermal buildup, triggering the protection circuit or — worst case — battery damage. Keep at least 6 inches of clearance on all sides.

3. Never Use in Flooded Areas

Water and electricity don't mix. Even though some units have IP ratings, no portable power station is designed to operate while submerged. If your apartment floods during a storm, move the power station to higher ground before using it.

4. Never Daisy-Chain (Unless Supported)

Connecting the output of one power station to the input of another can create dangerous voltage loops. Some units like the EcoFlow Delta Pro support parallel connection with a special cable, but never use standard extension cords to link stations.

5. Never Exceed the Continuous Wattage Rating

Every power station has a max continuous output (e.g., 1800W). Plugging in devices that exceed this will trigger the overload protection and shut down the station — or damage the inverter. Check the wattage of everything you plug in.

6. Never Use Damaged or Third-Party Chargers

Always use the manufacturer's AC adapter and solar charging cable. Third-party chargers may not have proper voltage regulation or temperature protection, increasing fire risk.

7. Never Expose to Extreme Temperatures

Most power stations operate between 32°F–104°F (0°C–40°C). Charging below freezing damages lithium batteries permanently. Leaving a station in a hot car in summer can trigger thermal shutdown or battery degradation.

8. Never Ignore Warning Signs

If the battery bulges, makes hissing sounds, or emits unusual odors — stop using it immediately. Move it to a safe, outdoor area if possible and contact the manufacturer. These are signs of thermal runaway.

9. Never Disassemble or Modify

Power stations contain high-voltage battery packs (24V–60V DC) that can deliver dangerous shocks. Internal repair should only be done by qualified technicians. Modifying the battery or inverter voids warranty and creates serious safety risks.

10. Never Leave Charging Unattended for Extended Periods

While most modern stations have auto-shutoff when fully charged, it's still good practice to unplug once charging is complete. This reduces wear on the battery management system and eliminates any fire risk from electrical faults.

What to Do Instead

• Store at 60% charge in a cool, dry place
• Check charge level every 3 months
• Keep the station in a visible, accessible location
• Use a surge protector for sensitive electronics
• Register the product for warranty and recall notifications
