Backup Power Safety Basics

Backup power is useful, but it is still power equipment. The safest setup is the one you understand before the outage starts.

Portable batteries

• Keep vents clear.
• Do not exceed rated AC output.
• Do not treat a portable battery as a hardwired home battery.
• Use grounded, properly rated cords.

Gas generators

Gas generators belong outside, far from doors, windows, garages, and vents. Carbon monoxide is the reason battery stations are often better for indoor essentials.

Medical devices

For CPAP machines and other medical devices, verify manufacturer guidance and talk with a clinician or equipment provider if uninterrupted power is medically important.

Indoor vs outdoor safety

Portable power stations are popular because they can power small essentials indoors without engine exhaust. Gas generators are different. They produce carbon monoxide and must run outdoors only, far from doors, windows, vents, crawlspaces, and garages. Never bring a gas generator inside because the weather is bad.

Cord and load safety

• Use properly rated extension cords and avoid running cords under rugs.
• Do not overload a station just because it has multiple outlets.
• Keep battery vents clear and avoid covering the unit with blankets or boxes.
• Do not backfeed a home through a dryer outlet or wall outlet.
• Use a transfer switch or interlock only if it is properly installed for that purpose.

Medical-device safety

For CPAP machines, oxygen equipment, refrigerated medicine, or other health-related needs, check the device manufacturer guidance and talk with a qualified medical or electrical professional when needed. A consumer power station can be helpful, but it should not be your only plan for life-safety equipment.
