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
EF ECOFLOW Portable Power Station DELTA 2, 1024Wh LiFePO4 (LFP) Battery, 1800W AC/100W USB-C Output
Pros
- Pure sine wave inverter (1800W continuous, 2700W surge) supports many CPAP machines and some oxygen-concentrator setups within tested wattage limits
- 1024Wh LiFePO4 (LFP) battery can carry many non-humidified CPAP setups overnight after a full-device test
- Charges to 80% in ~50 minutes via AC wall outlet — fast top-up between storms or before a predicted outage
- Six AC outlets (US model) plus USB-C 100W; enough for a measured bedside load such as CPAP, lamp, phone, or medication fridge
- 10-year LFP battery lifespan (~3000 cycles to 80%) vs. ~500 cycles for older lithium chemistries
Cons
- 26 lbs — heavy for a frail elderly user to move alone; needs a fixed bedside location
- App-based remote monitoring requires smartphone familiarity (app optional, not required for basic use)
- At $449 MSRP it is the most expensive item in this kit; sale prices of $399–$428 are common
- Not a medical-grade UPS or life-support backup; EcoFlow lists 30ms EPS transfer and says compatibility must be tested
- EcoFlow warns against using it for medical emergency equipment related to personal safety without device/manufacturer guidance
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.
EF ECOFLOW Portable Power Station DELTA 2, 1024Wh LiFePO4 (LFP) Battery, 1800W AC/100W USB-C Output
The DELTA 2 is a strong caregiver-room power station, not a universal medical backup. Its 1800W pure-sine inverter and 1024Wh battery can run many CPAP and some oxygen-concentrator setups within wattage and surge limits, but the exact machine, cable, humidifier setting, and AC timeout behavior must be tested. Use it for capacity; use a dedicated CPAP battery or medical-grade backup when uninterrupted failover or life-safety equipment is involved.
