How long will a BLUETTI Elite 100 V2 run a CPAP machine? (US 120 V)
Yes, it runs it 26 h
Includes this load’s 100% duty cycle and the station’s 10 W idle draw — not a label-wattage guess.

No start-up rail: this load has no locked rotor to publish an inrush for, so no start-up demand was checked.
Two numbers decide this, and readers use them interchangeably: watts are the ceiling on what the inverter holds at any instant, watt-hours are how much energy the battery holds. A machine can have plenty of one and not enough of the other.
The verdict is a calculation, not a lookup; the hours are a division, not the nameplate watt-hours. The working is in the evidence below.
This page answers an electrical question, not a medical one.
Where this page puts hours on a pairing, that figure is how long a power station’s battery lasts running this machine’s wattage — an electricity calculation, not a judgment about whether a break in therapy is safe. A small watt figure alone does not settle a verdict here either: this machine also carries a documented waveform requirement, and a station with no waveform on record is held at a tight fit regardless of how easily it clears the watts.
Where a verdict below reads a tight fit — the amber triangle on a row in the list of stations — read it as don’t rely on this pairing, whatever reason the row gives for that particular verdict, and not as a compromise likely to hold anyway. That state means the same thing here however it was arrived at: this site cannot clear the pairing with confidence, and that isn’t a passing grade with a footnote. Where a row says a check could not be run at all, that is a weaker claim than a near miss, not a stronger one.
What to do about a power interruption during therapy is a question for a clinician, the durable medical equipment (DME) supplier who set the machine up, or the manufacturer’s own guidance for it — not for this site. For the electricity side of an outage plan, this page can help: what a station needs to run this machine at all, and — where both makers publish enough to work it out — how long a given battery keeps it running.
Where those numbers come from
A blank is never left blank. A field we have found no figure for says so, and a field whose sources disagree — two documents, or one document with itself — says that instead of picking one.
What a CPAP machine demands
The inverter is loaded to 44 VA — 22 W ÷ 0.50 — which is the quantity its ceiling is actually measured against.
What the BLUETTI Elite 100 V2 offers
The arithmetic: 1,024 Wh nameplate × 90% depth of discharge × 90% inverter efficiency = 829.4 Wh
BLUETTI publishes the coefficients but not this figure, so it is computed rather than copied.
What the machine consumes just being switched on. It sits in the runtime denominator alongside the load.

If this is not the pairing
BLUETTI Elite 30 V2 (US 120 V) reaches the same conclusion on a CPAP machine at 600 W continuous, and it is $239. Cheaper is only cheaper when the answer is the same — this one is. See that pairing →
