Pros & Cons
Anker 737 Power Bank PowerCore 24K
Pros
- High-capacity USB-C power layer for phones and satellite devices
- 140W-class output supports laptops and fast phone charging
- Display makes charge state obvious
- Compact enough for a command-post drawer
- Useful every day, not just during emergencies
Cons
- No radio or alert capability by itself
- Does not run a normal AC modem/router stack without a tested converter or DC path
- Needs to be kept charged before storm season
- More expensive than basic 10K power banks
- Airline and storage rules still matter
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
Anker 737 Power Bank PowerCore 24K
The Anker 737 is the phone and USB-C power layer that makes the rest of the kit usable. A radio plan fails if phones, satellite messengers, and USB-C radios are dead. Keep it charged in the same drawer as the written outage plan, but use a small power station or UPS for ordinary AC network gear.
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.
