If you rely on medical equipment at home — a CPAP machine, an oxygen concentrator, or refrigerated medication — a power outage is more than an inconvenience. A backup power station keeps that equipment running when the grid doesn't, and sizing it correctly ahead of time means you're not figuring it out in the middle of an emergency.

Typical Power Draw by Device

• CPAP, no humidifier: ~30W, roughly 250Wh per night.
• CPAP, with humidifier: ~50–60W, roughly 500Wh per night.
• Portable oxygen concentrator: ~100–200W, roughly 800Wh over an 8-hour night at 2 LPM.
• Home oxygen concentrator: ~300–600W continuous — a substantially heavier load than portable models.
• Refrigerated medication: needs continuous, independent cold storage — a dedicated portable fridge/freezer is worth considering rather than relying solely on a shared power station.

Light, Medium, and Heavy Use

• Light use: A single CPAP without a humidifier, backed up for one to two nights. Look for 250–500Wh of capacity — our Compact range (up to 500Wh) covers this well.
• Medium use: A CPAP with humidifier, a portable oxygen concentrator, or one device plus incidental charging (phone, monitor), backed up for multiple nights. Look for 1,000–1,500Wh of capacity with at least 200W of continuous output — our Mid-Range collection (500–1,500Wh) fits here. If outages might run past a day or two, a portable solar panel is worth pairing in.
• Heavy use: A home oxygen concentrator, a powered wheelchair, or several critical devices running at once, including independent medication refrigeration. Look for 2,000Wh or more with at least 600W of continuous output to handle a home concentrator's heavier draw — our High Capacity or Ultra-High Capacity collections fit here. An expansion battery extends backup across multiple days.

Always test your specific equipment against a power station's actual output before relying on it in an emergency — rated capacity and continuous output can vary between units.
