Important (read first): This guide covers electrical specs and planning math only: capacity (Wh), outlets, UPS switchover times, and manufacturer noise figures. It is not medical advice. Watt Weekender has not tested any CPAP machine with any power station. Confirm AC or DC-adapter compatibility with your CPAP manufacturer and talk to your clinician about backup power for your prescribed settings (pressure, heated tubing, humidifier). Those settings change watt draw a lot, so the examples below use hypothetical watts.
Specs only, not hands-on tested. All three stations’ figures come from BLUETTI’s US product pages (spec tables, comparison tables, and FAQs), checked 2026-10-11. Where BLUETTI publishes two numbers, we show both.
Short version: on paper, the Elite 30 V2 (288 Wh, 9.48 lb) fits only low-draw nights, and BLUETTI’s own runtime formula puts a 40 W load at about 5.5 hours. The Elite 100 V2 (1,024 Wh, 25 lb) and AC180 (1,152 Wh, about 35–37 lb) both cover roughly one to two 8-hour nights at 40–80 W. The Elite 100 V2 lists a faster UPS switchover (≤10 ms vs 20 ms), lower noise (30 dB vs 40 dB), and is about 10 lb lighter. The AC180 has about 12% more capacity (128 Wh).

Noise figures come from different test conditions, so treat them as rough guides, not a head-to-head measurement.
Runtime math using BLUETTI’s own formulas
BLUETTI publishes a runtime formula for each station:
Runtime (h) ≈ capacity (Wh) × DoD × inverter efficiency ÷ (load W + self-consumption W)
| Station | DoD | Inverter efficiency | Self-consumption used | Usable Wh on AC (≈) |
|---|---|---|---|---|
| Elite 30 V2 | 95% | 90% | 4.5 W (AC only) | ≈246 Wh |
| Elite 100 V2 | 90% | 85% (“over 85%”) | 10 W | ≈783 Wh |
| AC180 | 90% | 85% | 15 W | ≈881 Wh |
Hypothetical CPAP loads on the AC outlet (replace with your own measured watts):
| Average draw (hypothetical) | Elite 30 V2 | Elite 100 V2 | AC180 |
|---|---|---|---|
| 30 W (low setting, no humidifier) | ≈7.1 h | ≈19.6 h | ≈19.6 h |
| 40 W | ≈5.5 h | ≈15.7 h | ≈16.0 h |
| 60 W (heated tubing) | ≈3.8 h | ≈11.2 h | ≈11.8 h |
| 80 W (humidifier high) | ≈2.9 h | ≈8.7 h | ≈9.3 h |
In 8-hour nights, that’s about 0.4–0.9 nights for the Elite 30 V2, about 1.1–2.5 nights for the Elite 100 V2, and about 1.2–2.5 nights for the AC180 across the 30–80 W range. These are planning numbers, not promises. Results vary with temperature, battery age, and how your machine actually draws power through the night, and BLUETTI labels its formula as reference only.
Self-consumption matters more on small loads. At 40 W, the AC180’s ~15 W overhead is more than a third of the load, which is why it barely out-runs the Elite 100 V2 despite 128 Wh more capacity. Turn off outputs you aren’t using (BLUETTI lists the Elite 30 V2 at 9 W with AC and DC both on vs 4.5 W AC only).
Want to plug in your own numbers? Use the Watt-Hour Calculator, or measure your machine for a night at home with a plug-in watt meter. That beats any estimate.
AC outlet vs 12 V outlet
- AC outlet (the CPAP’s normal power brick): the simplest path. The inverter costs some energy, which is already in the formula above.
- 12 V car outlet with your CPAP maker’s DC cable: often more efficient because it skips the inverter, but only use a DC cable or converter your CPAP manufacturer lists as compatible. All three stations have a regulated 12 V/10 A car outlet. BLUETTI doesn’t publish a DC-path runtime formula, so we don’t estimate one here.
- USB-C: don’t assume USB-C will run a CPAP unless your machine’s maker says so.
UPS switchover: does 10 ms vs 20 ms matter?
If you plan to leave the CPAP plugged into the station while the station is plugged into the wall (so it switches over during an outage), the switchover time is the number to check. BLUETTI lists ≤10 ms for the Elite 30 V2 and Elite 100 V2, and 20 ms for the AC180. Whether your specific machine rides through either is a question for your CPAP maker, and worth testing at home by unplugging the station from the wall while the machine runs (your test, not ours).
Flying with a CPAP power station
The FAA’s PackSafe rules for passengers limit lithium-ion batteries to 100 Wh each, or 101–160 Wh with airline approval (up to two spares). All three stations are far above that (288 Wh and up), so none of these is a flight battery. For air travel, ask your CPAP maker about its own approved travel battery and check your airline’s rules before you go.
Who should lean which (constraints, not medical rankings)
- Elite 30 V2: short naps, very low verified draw, or as a small bedside UPS for a single night’s partial outage. At 9.48 lb it’s the only one that’s genuinely light. It’s not a full-night pick for heated tubing or a humidifier on paper.
- Elite 100 V2: the balanced pick on paper for outage backup or car camping. It covers about one to two nights at 40–80 W, has ≤10 ms UPS, a 30 dB rating, and 1,000 W solar input for refilling on multi-day trips. See solar charge-time math.
- AC180: a bit more capacity for about 10 lb more weight and a slower 20 ms UPS rating. It makes the most sense if the higher-draw end of your range (60–80 W) is common and weight doesn’t matter.
- Other brands or a budget cap: compare against Jackery and EcoFlow in our CPAP travel guide and under-$500 roundup.
Quick checklist
- Read your CPAP manual for input volts and watts, and whether a DC cable exists for your model.
- Measure or estimate your nightly watts at your real settings.
- Run the formula above with margin, then pick a Wh class.
- Test one full night at home before you rely on it.
- Plan recharging: wall, car, or solar.
- Tell your clinician you’re planning battery backup and follow their guidance.
