CPAP Backup Portable Power
CPAP backup is about reliable overnight power for a medical device. This page filters out units too small for a meaningful night of use (under 240 Wh), anything with a modified-sine inverter, and units too heavy to live beside a bed or travel with (over 15 kg). Ranking rewards a documented pure-sine-wave output, usable capacity, and low weight. This index does not fabricate runtime hours — CPAP draw varies enormously with pressure and humidifier settings; check your device's draw against each unit's capacity.

What matters for CPAP backup
Waveform
Pure sine wave output is the safe default for medical electronics. Units whose official docs don't state a waveform rank below those that do.
Usable capacity
More watt-hours means more nights — especially with a humidifier, which multiplies draw.
Bedside practicality
A unit you can lift onto a nightstand or pack for travel beats a garage monolith.
DC options
Many CPAPs accept 12 V DC input, which skips inverter losses — check each product's port map.
Who this is for — and who should skip it
Good fit
- CPAP users wanting outage protection for overnight therapy
- Campers and travelers running a CPAP off-grid for one or more nights
Skip this page if
- Users whose CPAP officially requires a certified medical UPS — none of these units is one; several manuals explicitly exclude medical equipment
- Whole-home backup shoppers — see the home backup page
Hard disqualifiers (applied before any ranking)
- Battery capacity below 240 Wh — obviously too small for meaningful overnight use
- Modified sine wave output — unsafe default for medical electronics
- Unit weight above 15 kg — impractical beside a bed or in luggage
9 of 26 indexed products are filtered out by these rules — each is listed below with its reason. Ranking only ever happens among the 17 products that pass.

Related comparisons
1 kWh Class: EcoFlow DELTA 2 vs BLUETTI AC180 vs Jackery Explorer 1000 v2 vs Anker SOLIX C1000 vs Pecron E1000LFP
Five US-market 1 kWh-class LiFePO4 stations compared on official specs. All but the Explorer 1000 v2 deliver 1,800 W continuous; they diverge sharply on weight (10.8–16 kg), solar input (400–600 W), expansion (none to 4,864 Wh), and recharge behavior.
Mid Capacity: BLUETTI AC70 vs Pecron E600LFP vs Goal Zero Yeti 500 vs Goal Zero Yeti 700 vs Anker SOLIX C800 Plus
Five US-market LiFePO4 stations between 499 and 768 Wh. Output philosophy splits them: BLUETTI, Pecron, and Anker push 1,000–1,200 W inverters into this size class, while Goal Zero pairs smaller 500–600 W inverters with 4,000-cycle packs and sub-20 ms switching.
How this page decides
This page is generated from the index's normalized product records — official-manufacturer specifications with per-field provenance — using explicit fit rules, not editorial taste. Hard disqualifiers run first; ranking happens second, only among eligible products. Eligible products are scored as: documented pure sine wave (+80), capacity ×0.15 (capped at 1,100 Wh — beyond that adds little for CPAP), lightness (15 kg − weight) ×8, documented switchover (+30). No runtime hours are computed or claimed.
No runtime hours or real-world measurements are invented: every number traces to the source claims on each product page. Merchant relationships never affect these rules. See the methodology for the full data policy, and the JSON version of this page for machine consumption.
