If someone in your house depends on an electric-powered medical device, the planning mistake is starting with the generator. The real first step is smaller and less exciting: get the exact specifications for your exact device, confirm what your care team wants you to do, and decide where you’ll go if backup power isn’t enough. A generator or battery bank is one layer of that plan — not the plan itself, and not a guarantee that the device keeps running when you need it most.
This page walks through that coordination in order, then gives you a one-page worksheet to fill in with your own household’s information. It does not tell you which generator to buy or how long your specific battery will last — nobody can answer that without your device’s manual and your provider’s input.
Why “Buy a Generator” Is the Wrong First Step
Medical devices that depend on electricity cover a wide range of equipment — oxygen concentrators, ventilators, feeding pumps, dialysis equipment, power wheelchairs and scooters, suction machines, CPAP and BiPAP machines, and more. Each has different power needs, different built-in battery backup (if any), and different tolerance for an interruption.
Ready.gov’s power-outage guidance tells people who rely on electric medical devices to talk with their medical provider about a power-outage plan before an outage happens, not during one. That ordering matters: a generator bought without that conversation can still leave you with power that doesn’t fit the device, or that starts too slowly to matter.
Step 1: Get the Exact Information on Your Device
Before anything else, pull together what your equipment manual and manufacturer actually say about your device. You’re looking for:
- The exact model name, model number and serial number
- Whether the device has built-in battery backup, and how it’s described in the manual
- The manufacturer’s and equipment provider’s contact information, including an after-hours or emergency number if one is listed
- Whether the device has a manual, non-electric backup option — some do, many don’t
Write this down on paper and keep it somewhere easy to grab. A phone works until it doesn’t — once it’s dead, a note saved only in an app isn’t reachable.
Step 2: Confirm the Plan With Your Care Team
Your device’s manual tells you what the equipment can do. Your care team tells you what you should do with the specific device prescribed to you or your family member. Ready.gov directs people who rely on electric medical devices to talk with their provider about a power-outage plan and to ask how long any battery backup is expected to last for that piece of equipment.
Questions worth bringing to that conversation:
- How long can this device run on battery backup before it needs grid or generator power again?
- Is there a safe manual alternative if the device stops, even temporarily?
- At what point should we stop troubleshooting at home and get the person to a facility with reliable power?
It’s also worth asking your power company whether it offers a registry or priority-notification program for customers who depend on life-sustaining equipment. Some utilities run these programs and will flag your account for advance notice of planned outages. The honest limit here: not every utility offers one, and even where a program exists, it’s typically a notification system, not a guarantee of faster restoration in a widespread outage — treat it as one extra layer of information, not your backup plan.
Step 3: Decide Where You’d Go if Backup Power Isn’t Enough
Backup power can fail, run short, or simply not be an option in a given situation. Ready.gov’s own guidance tells people to identify, ahead of time, an alternate location they can go to if heat or cold becomes extreme during an outage. The same logic applies directly to medical equipment: decide now, while you have time to think clearly, where you’d go if a device at home can’t be safely powered — a relative’s house with power, a hospital, or a community location your local emergency management office has identified.
Write down the address, the route, and who in the household needs to be ready to move and how.
If mobility is part of what makes relocation harder — stairs, a wheelchair, limited transportation — our guide for when a family member can’t use the stairs during an outage covers that piece specifically.
Step 4: If You Do Add Backup Power, Follow the Safety Rules Exactly
Once the device information, the care-team plan and the relocation plan are settled, a battery backup or generator becomes one more layer — not the foundation. If a portable generator is part of your household’s plan, the Consumer Product Safety Commission’s rules are not flexible:
- Never run a portable generator indoors, including in a garage, basement, crawlspace or shed — opening doors and windows does not make it safe
- Keep the generator outdoors and away from windows, doors and vents
- Keep the generator dry, and never touch it with wet hands — a wet generator can shock you
- Let the engine cool before refueling
- Install working carbon monoxide alarms with battery backup, and test them
Carbon monoxide from a generator is invisible and can kill in minutes. That rule doesn’t bend because someone in the house needs the device running — if you can’t place the generator safely, the device goes on the relocation plan instead. For the full placement and cord-safety breakdown, see our generator carbon monoxide and extension-cord safety guide. If you haven’t sized out what a generator or power station would actually need to run, the backup power load calculation guide is the next step for that decision, separate from the device-and-care-team coordination this page covers.
Your One-Page Household Decision Worksheet
Copy this into a notebook or printed sheet and fill it in for each person in the household who depends on electric medical equipment. It’s organized into three parts, in the order they matter most.
Immediate Actions (Do This Week)
- Write down each device’s exact model, serial number and manufacturer contact info
- Call your medical provider or equipment supplier and ask the battery-backup and manual-alternative questions above
- Ask your power company whether it offers a medical-equipment registry or priority-notification program, and enroll if it does
- Pick and write down one specific relocation location with reliable power, plus the route to get there
Information to Gather From Sources, Not Guesses
- Your device manufacturer’s stated battery-backup duration for your exact model
- Your care team’s written instructions for a power interruption, including any manual backup steps
- Your local emergency management office’s list of community locations with backup power, if one exists
Purchases to Defer Until the Above Is Settled
- Any generator, battery bank or power station — size and type should follow your device’s actual power needs, not come before them
- Extension cords, transfer switches or wiring accessories specific to a power source you haven’t chosen yet
- Anything marketed as a guaranteed solution for medical devices — no backup power product can promise uninterrupted life support, and a claim that says otherwise is a red flag, not a feature
A Few Limits Worth Being Direct About
This page gives you a structure to build a plan — it does not replace your device’s manual, your equipment manufacturer’s guidance, or your clinician’s instructions. No generator, battery backup or power station discussed on this site is a guarantee of uninterrupted power or life support. A utility registry, where one exists, is a notification tool, not a promise of priority restoration. If a device stops working and the situation feels urgent, follow your care team’s emergency instructions or seek medical help directly rather than troubleshooting the power source first.
For the rest of your household’s outage plan — water, food, lighting and communication — the full power outages and heating guide covers each piece in order, and the household water storage plan is worth building out alongside this one if pets are part of the household too.
