Pros & Cons
Anker 40W Dual USB-C Car Charger with Power Delivery (PowerIQ 3.0)
Pros
- Dual USB-C with PowerIQ 3.0 — fast-charges any modern phone simultaneously on both ports
- Compact 12V plug keeps the dash uncluttered; stable fit in cigarette lighter port
- 40W split across 2 ports handles radio mic charge + phone at the same time
- Works in 12V and 24V vehicles (RV house circuits, trucks, vans)
- Under $20 — best price-to-performance for a rig charging hub
Cons
- Only 2 ports — larger RV builds with 4+ devices need a separate USB hub or powered strip
- No USB-A port — legacy devices need USB-A to USB-C adapter
- No 12V pass-through socket — can't power accessories that need the lighter port itself
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 40W Dual USB-C Car Charger with Power Delivery (PowerIQ 3.0)
The Anker PowerDrive III Duo is the no-brainer 12V charging hub for any RV or van kit — dual fast-charge USB-C ports, sub-$20 price, and Anker reliability make it the default 'keep everything topped off while driving' piece. For rigs with 4+ devices, pair with a second unit or step up to a powered USB hub mounted to the dash.
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.
