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
- 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) — safe for all CPAP machines, oxygen concentrators, and sensitive medical equipment; manufacturer explicitly rates it for medical devices
- 1024Wh LiFePO4 (LFP) battery runs a typical CPAP (30–90W, no humidifier) for 11–30+ hours on one charge
- 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 CPAP, lamp, phone, and medication refrigerator simultaneously
- 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
- No built-in auto-transfer/UPS — short gap on power loss (milliseconds) vs. true UPS, fine for most CPAPs
Our Verdicts
Anker 737 Power Bank PowerCore 24K
The Anker 737 is the 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.
EF ECOFLOW Portable Power Station DELTA 2, 1024Wh LiFePO4 (LFP) Battery, 1800W AC/100W USB-C Output
The DELTA 2 is the right power station for a caregiver kit: its 1800W continuous pure sine wave inverter and 2700W surge handle every CPAP machine and most home oxygen concentrators (30–500W) without compatibility concerns — the manufacturer explicitly certifies pure sine output. A typical CPAP at 50W draws less than 1/36th of its 1024Wh capacity, yielding 15–20+ hours on a single charge with no habits required beyond plugging in and pressing one button. It is the one piece of equipment that protects the one piece of medical equipment that cannot be skipped.
