Using a portable power station indoors is the safest way to survive a blackout, but many new owners are worried about fumes. One of the most common questions we get—especially from those using medical devices like CPAP machines—is simply: “Is it safe to sleep next to this thing?”
Unlike traditional gas generators that spew deadly fumes, a portable power station indoors is generally safe. However, “safe” doesn’t mean “risk-free.” In this 2026 safety guide, we will cover the silent risks you must know: Heat accumulation, Pass-Through charging stress, and Battery Chemistry.
1. The Golden Rule: Battery vs. Gas
First, let’s clear up the confusion that scares many beginners.
- Gas Generators: ❌ NEVER use indoors. According to the CPSC, they produce Carbon Monoxide (CO) which is invisible, odorless, and kills in minutes.
- Portable Power Stations: ✅ Safe. You can use a **portable power station indoors** without any ventilation issues. They emit zero fumes because they store electricity chemically rather than generating it via combustion. You can use them in your bedroom, tent, or car without venting.
2. Can You Charge It While Using It? (Pass-Through Safety)
A frequently asked question in our community is: “Can I use my Jackery while it is charging from the wall?”
The answer is Yes, this is called Pass-Through Charging. However, strictly from a safety and longevity standpoint, you need to be careful:
- Heat Generation: Doing this generates double the heat (charging heat + discharging heat).
- Battery Stress: It puts extra stress on the internal cells if done daily.
- Recommendation: Only use Pass-Through for low-wattage devices (like phones or a router). Do not run a heavy heater while charging the battery!
Pro Tip: If you have used pass-through charging frequently and your device now refuses to hold a charge, it might be a BMS error, not a dead battery. Check our troubleshooting guide on Why Is My Jackery Not Charging? (7 Fixes).
3. Is It Safe for Bedroom Use (CPAP)?
If you rely on a CPAP machine for sleep apnea, you are likely placing the battery right next to your head while sleeping.
- Noise Levels: Most modern units like the EcoFlow RIVER 2 are whisper-quiet (under 30dB), so they won’t disturb your sleep.
- Ventilation: The real risk isn’t fumes, it’s overheating. Ensure the device has at least 6 inches of space for its fans to breathe. Do not cover it with a blanket or pillow!

4. Kitchen Safety: Running Refrigerators
When a blackout hits, preserving food is priority #1. You can absolutely run a refrigerator indoors with a solar generator.
- Placement: Do not put the power station behind the fridge where hot coils are located. Place it to the side for better airflow.
- Surge Protection: Most modern units have built-in BMS (Battery Management Systems) to protect your appliances against voltage surges.

5. Fire Risks: Why Chemistry Matters
As we discussed in our recent Lifespan Guide, the type of battery inside determines its thermal safety.
- LFP (LiFePO4): Found in the EcoFlow DELTA 2 and Jackery 1000 v2. These are chemically stable and extremely unlikely to catch fire even if punctured.
- NCM (Older Lithium): Prone to “Thermal Runaway” if damaged or overheated. If you use an older model indoors, keep it away from curtains and flammable materials.
Final Verdict
Yes, using a portable power station indoors is the safest way to survive a power outage in 2026. Whether you are keeping your CPAP running or keeping the lights on, just remember to give the battery “room to breathe.”

FAQ
Q: Do portable power stations emit radiation?
A: They emit a very small amount of EMF (Electromagnetic Fields), similar to a laptop or TV. It is considered safe, but if you are sensitive, keep the unit 3 feet away from your head while sleeping.
Q: Can I leave it plugged in all the time as a UPS?
A: Yes, models like the EcoFlow series support EPS/UPS mode. This is safe for indoors and ensures your devices stay on during a blackout without damaging the battery.
Q: Does it get hot during use?
A: The AC inverter generates heat when converting power. The fans will turn on to cool it down—this is normal. Just ensure the intake/exhaust vents are not blocked against a wall.
Q: Is it legal to use a portable power station indoors in an apartment?
A: Yes, using a portable power station indoors is 100% legal and safe in apartments because there are no emissions or fire hazards like gas generators.
