Pros & Cons
Medistrom Pilot-24 Lite CPAP Battery Backup Power Supply, 95Wh, for ResMed AirSense 10, AirMini, S9, and compatible 24V CPAP/APAP devices (bundled with cables)
Pros
- Seamless UPS-mode failover: the Pilot-24 Lite passes AC power through to the CPAP normally and switches to battery in milliseconds on power loss — no buttons, no action required from a sleeping user
- 8–16 hours runtime at typical CPAP pressures (up to 10 cmH2O), covering a full night in most outage scenarios
- Purpose-built for ResMed AirSense 10, AirMini, and S9 with included cables — no adapters to buy or guess at
- TSA-approved / FAA-compliant 95Wh battery: also travels with the CPAP user
- Recharges in 2–3 hours; lighter (1.3 lb) and smaller than a general-purpose power station
Cons
- Works only with compatible 24V CPAP/APAP devices — not universal; verify CPAP model before buying
- At $339 it is expensive per watt-hour versus a general power station, but the pass-through UPS function justifies the premium for CPAP-critical use
- 95Wh is not enough to run other devices simultaneously — single-purpose
- Not compatible with ventilator BiPAP or high-flow oxygen concentrators
Midland WR400 Deluxe NOAA Weather Alert Radio with SAME Localized Programming, 80+ Emergency Voice & Flashing Alerts, Alarm Clock/AM-FM Radio
Pros
- Plug-in with 4-AA battery backup: continues alerting through a power outage — exactly the moment it is needed most
- SAME (Specific Area Message Encoding) county-level programming filters out irrelevant state-wide alerts; only the user's county wakes the device
- Three alert modalities — 85 dB siren, synthesized voice announcement, and tri-color flashing LED — accessible to elderly users with hearing or vision impairment
- 80+ alert types (NWS weather + civil FEMA alerts) with no subscription, no app, no internet required
- Dual alarm clock + AM/FM radio: replaces bedside radio so it stays plugged in and relevant 24/7
Cons
- Programming the SAME county codes requires reading the manual once — not truly zero-setup out of the box
- Siren at 85 dB can startle; elderly users with heart conditions may want to lower the alarm volume in settings
- No battery-only portable mode beyond backup AA cells; not designed for travel
Our Verdicts
Medistrom Pilot-24 Lite CPAP Battery Backup Power Supply, 95Wh, for ResMed AirSense 10, AirMini, S9, and compatible 24V CPAP/APAP devices (bundled with cables)
The Pilot-24 Lite is the best secondary layer for a CPAP user who wants guaranteed overnight coverage without relying solely on the larger DELTA 2: it sits invisibly in-line with the CPAP, passes power through when the grid is live, and switches to battery the moment power fails — with zero intervention needed from a sleeping elderly parent. Pairing it with the DELTA 2 provides belt-and-suspenders CPAP coverage: the Pilot-24 handles the first 8–16 hours autonomously while the DELTA 2 holds capacity for everything else in the room.

The WR400 is the correct choice for a caregiver kit because it requires no new habits: plug it in, program the home county once, and it wakes the household with voice announcements and flashing lights 24/7 — even during a power outage via AA backup. For an elderly parent who cannot monitor a smartphone or app during a night storm, a dedicated plug-in alert device that shouts and flashes is the most reliable last line of warning.
