Will an Anker SOLIX Solarbank 3 E2700 Pro run a CPAP machine? (EU)
Tight fit — no usable-capacity figure see why below ↓
This load’s manufacturer asks for a pure sine wave and we have found no published inverter waveform for the EU build. The watts are not the problem — the refusal to assume a waveform is.

0 – 1,200 W across the rails above
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. What it will not do is print a runtime, and the reason is specific: we have found no published depth of discharge or inverter efficiency for the EU build, so there is no usable-capacity figure to divide.
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.
No usable-capacity figure for this machine
Anker SOLIX states a nameplate watt-hour number for it, and we have found no published depth of discharge or inverter efficiency for the EU build. Dividing the nameplate by this load would be wrong by 20–35% in the flattering direction, so this page shows the nameplate for what it is and refuses to turn it into hours.

The surge ceiling on this page is ours, not the manufacturer’s
We have found no published surge rating for the EU build. So the start-up check runs against the continuous output instead — an inverter cannot surge below what it sustains, which makes that the safest number we can defend. Real inverters usually manage 1.5–2× their continuous rating, so a start-up call held back by this figure may well be fine in practice; we are not going to say so until the manufacturer does.
Energy rate instead of a runtime
22 Wh per hour averaged over this load’s duty cycleThis number needs no battery figure at all, which is why this page can give it when it cannot give hours. Divide any usable-capacity figure you trust by it and you have your own runtime, with our arithmetic visible instead of hidden.
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 Anker SOLIX Solarbank 3 E2700 Pro offers
This figure is ours, not the brand’s: the continuous rating used as a conservative floor because we have found no surge rating for the EU build.

If this is not the pairing
BLUETTI Elite 30 V2 (EU 230 V) — 600 W continuous, and it holds a CPAP machine for about 7.9 h · from €219. See that pairing →
Anker SOLIX C300 (EU 230 V) reaches the same conclusion on a CPAP machine at 300 W continuous, and it is €269.99. Cheaper is only cheaper when the answer is the same — this one is. See that pairing →
