Pros & Cons
Earth Pak Original Waterproof Dry Bag 20L, Roll-Top Closure, 500D PVC, IPX5
Pros
- 500D PVC construction is genuinely rugged and flood-resistant
- Roll-top closure is foolproof and requires no zippers to fail
- IPX5 rated — handles high-pressure water spray from any angle
- Floats if submerged briefly (5–10 sec)
- Under $30 — low-cost insurance for expensive electronics
Cons
- Not rated for sustained submersion — not for diving or flooding scenario where kit is underwater for minutes
- 20L is adequate but not large enough for full kit in one bag
Medistrom Pilot-24 Lite CPAP Battery Backup Power Supply, 95Wh, for ResMed AirSense 10, AirMini, S9, and select compatible 24V PAP devices
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 select other 24V PAP devices supported by separate cable kits
- 95Wh capacity sits under the FAA 100Wh spare-lithium threshold, so it is practical for carry-on CPAP travel
- 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 the exact CPAP model and cable before buying
- Heated humidifiers, heated tubing, mask leaks, and high pressures can cut runtime sharply
- 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
Our Verdicts
Earth Pak Original Waterproof Dry Bag 20L, Roll-Top Closure, 500D PVC, IPX5
At under $30, the Earth Pak 20L is the most cost-effective way to protect phones, documents, radios, and chargers from hurricane storm surge and driving rain. The 500D PVC and roll-top closure handle IPX5 conditions reliably; just don't expect it to survive full submersion for more than a few seconds. Buy two and seal the electronics separately.
Medistrom Pilot-24 Lite CPAP Battery Backup Power Supply, 95Wh, for ResMed AirSense 10, AirMini, S9, and select compatible 24V PAP devices
The Pilot-24 Lite is the best secondary layer for a CPAP user who needs automatic overnight failover without relying solely on a larger power station. It sits in-line with a compatible 24V PAP machine, passes wall power through while the grid is live, and switches to battery when power fails. The catch is compatibility and runtime discipline: confirm the exact CPAP model and cable, test the real pressure setting, and plan to disable heated humidification when runtime matters.
