Backup Power for Medical Devices
When someone in your home depends on a CPAP, oxygen concentrator, or other medical device, a power outage can be frightening. The reassuring news is that clean backup power can help you ride one out — an inverter generator outside and a quiet pure sine battery indoors make a gentle, steady team. But the most important part isn't a machine at all: it's a written plan you build with your doctor and equipment supplier, because a generator is a bridge through an outage, not a guarantee. Here's the plain-English version, and there's a printable, 29-page guide up top if you'd like the full walk-through.
Common Questions
1 Can a generator keep a CPAP or oxygen machine running in an outage?
It can help a great deal, but please think of it as one piece of a larger plan, not the whole answer. Anyone who depends on a medical device should build a written emergency plan with their doctor and equipment supplier, register on the power company's medical list, and keep backup oxygen tanks on hand. A generator is a bridge through an outage, never a guarantee.
2 Is inverter power safe for a CPAP, nebulizer, or oxygen concentrator?
Yes. Inverter generators and good battery power stations make clean, pure sine wave power, which is the gentle, steady kind these devices are built for. What you want to avoid is cheap modified sine wave gear, like some bargain plug-in inverters and battery backups, which can make medical devices run hot or throw errors. When in doubt, look for the words pure sine on the label, or ask the device's supplier.
3 How do I run a CPAP overnight if the generator has to stay outside?
Because every fuel generator gives off carbon monoxide, it must run outdoors only. So the smart setup is a quiet pure sine battery power station indoors, right by the bed, running the CPAP overnight with no fumes and no noise. During the day you run the generator safely outside and use it to recharge the battery. Battery inside by night, generator outside by day.
4 What about an oxygen concentrator?
An oxygen concentrator draws a lot of power and is life-critical, so never rely on a generator alone for it. Your real backup for oxygen is backup tanks, which need no electricity to work; your doctor and supplier decide how many to keep and how to use them. A generator and a battery can help run the concentrator and stretch your tank supply, but the tanks are the safety net.
5 Should I tell my power company that someone here uses a medical device?
Yes. Most utilities keep a medical or priority list, so registering can mean faster restoration and advance notice of planned outages. It is free and worth doing. Just don't lean on it alone; it is one more layer alongside your doctor's plan, your backup power, and your spare oxygen. I'm glad to help you find and fill out the form.
6 Can I ever run the generator inside if it is truly an emergency?
No, never, and not even for a medical device. Carbon monoxide from a generator is invisible, odorless, and can kill quickly, even in a garage with the door open. That is the very reason we set up the indoor battery ahead of time, so you never need to bring the generator closer. Keep it outside, at least 20 feet from the house, every single time.
Want a Hand With Yours?
Picking a generator, setting it up, and learning to run it safely is one of my most-requested visits. I bring the patience and the know-how - you keep your seat. We'll match a unit to your home, set it up right, walk through starting it and staying safe from carbon monoxide, and get your internet, TV, and devices happily back on. $99 flat, and every visit is 30-day come-back-free. (330) 200-8042.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
