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
Medistrom Pilot-24 Lite CPAP Battery Backup Power Supply, 95Wh, for ResMed AirSense 10, AirMini, S9, and compatible 24V CPAP/APAP devices (bundled with cables)
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 included cables — no adapters to buy or guess at
- TSA-approved / FAA-compliant 95Wh battery: also travels with the CPAP user
- 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 CPAP model before buying
- 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
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.
Medistrom Pilot-24 Lite CPAP Battery Backup Power Supply, 95Wh, for ResMed AirSense 10, AirMini, S9, and compatible 24V CPAP/APAP devices (bundled with cables)
The Pilot-24 Lite is the best secondary layer for a CPAP user who wants guaranteed overnight coverage without relying solely on the larger DELTA 2: it sits invisibly in-line with the CPAP, passes power through when the grid is live, and switches to battery the moment power fails — with zero intervention needed from a sleeping elderly parent. Pairing it with the DELTA 2 provides belt-and-suspenders CPAP coverage: the Pilot-24 handles the first 8–16 hours autonomously while the DELTA 2 holds capacity for everything else in the room.
