How many watts does a variable-speed pool pump use?
PumpsAlso called: pool pump, variable speed pool pump, swimming pool pump
Two numbers decide whether a power station runs a variable-speed pool pump, and readers arrive using them interchangeably. Watts are the ceiling on what the inverter can hold at any instant — this load needs 627 W of them while it runs. Watt-hours are how much energy the battery holds. A machine can have plenty of one and not enough of the other.
Of the 26 station records we publish — every model we hold a page for, with its US and EU versions counted separately — 19 run it, 0 are a tight fit and 7 are out of reach. Each of those is a calculation against that machine’s continuous output, its surge ceiling and its inverter waveform — not a lookup table — and the reasoning is on every row.
The three numbers a power station is judged against
Running power121–627 W Official spec · verified 2026-08-09 · high confidence
This machine has no single running wattage — the band is its own, not a spread across models. Every verdict below is computed at the top of it, 627 W.
Start-up surgeNot found in the sources we checked no figure to date
Duty cycle100% Official spec · verified 2026-08-09 · medium confidence
This band is one machine turning itself up and down, not a spread across models, so there is no “which unit do I own” to resolve here. Where it sits moves with the conditions the machine is working in, which is why the runtimes below come out as intervals rather than as one number.
Start-up figure: No start-up figure found
We read 4 documents for this class on 2026-08-09 and found no published start-up figure in them. This library does not invent one: where a start-up check is required, the engine caps the verdict below green rather than assuming the machine starts cleanly.

What actually decides it
A variable-speed motor: it ramps instead of slamming
This compressor is fed by its own electronics, which start it gently and then modulate its speed to the work in front of it. The start-up peak is small or absent, and the running draw is a band rather than a point — low most of the time, climbing only under load. The binding constraint is usually the top of that band, not the start.
What kind of motor is inside
The motor is brushless and driven by its own inverter board, which is why the start-up demand is modest: the electronics ramp the motor rather than connecting it straight to the line.
There is no start-up figure, and there should not be
Nothing here has a locked rotor to publish a figure for: a heating element, a switch-mode supply and a variable-speed drive all start without an inrush worth rating. The absence of a start-up number on this record is a fact about the hardware rather than a hole in the library, so the engine does not cap any verdict below for it — which is the opposite of what it does when a figure is genuinely missing.
Which power stations run it
Every row is a live calculation against that machine's continuous output, surge ceiling and
inverter waveform. Of the 26 station
records we publish — US and EU versions counted separately — 19 run it, 0 are a tight fit and 7 are out of reach. The percentage is
this load as a share of that machine's continuous output; anything past 82% drops out of the green. Rows are ordered by verdict, then by
price — cheapest first inside each band.

What changes the numbers
Mains standards on recordUS 120 VThe figures above are recorded per mains standard, because the same appliance class is built differently on 120 V and 230 V. Where only one standard is on record, the ranking still lists machines from both regions — each row states its own.
Everything else we hold on this load
Each figure carries the tier it came from and the date it was checked. Sizing guidance is
kept apart from measured draw on purpose: one says what the machine pulls, the other says
what a manufacturer or a standard thinks you should buy for it.

A sizing figure, not a draw: it is what this class needs a machine to be RATED at, headroom included.
How many watts does a variable-speed pool pump use?
121–627 W while it is running. Those are different questions and most pages answer only the first. The running figure decides whether a machine can hold it; the start-up figure decides whether it can get it going at all, and it is usually the one that fails. We read 4 documents for this class on 2026-08-09 and found no published start-up figure in them.
What size power station do I need for a variable-speed pool pump?
For a variable-speed pool pump, the BLUETTI Elite 100 V2 (US 120 V) is the cheapest machine in our library that runs it, at 1,800 W continuous · 3,600 W surge ceiling and $499 against a running draw of 121–627 W. That is a verdict computed from this load’s running watts, its start-up demand and the inverter waveform — not a rule of thumb about doubling the wattage. 19 of 26 machines clear it.
How long will a power station run a variable-speed pool pump?
It depends entirely on the machine, which is the part most pages skip. Against a variable-speed pool pump at 121–627 W of running draw, our figures put the BLUETTI Elite 100 V2 at about 1.3–6.3 h, and the Jackery Explorer 1000 v2 at about 1.3–6.2 h. Those hours come from usable-capacity figures derived from each manufacturer’s own published usable-capacity coefficients — depth of discharge and inverter efficiency where a brand states them separately, with each machine’s idle draw in the denominator — not from dividing a nameplate watt-hour number by a label wattage. Most machines in the list carry no hours at all: we hold nothing for those builds that makes a usable-capacity figure defensible, so those rows give an energy rate instead of a number we would have had to invent.
Which power stations run a variable-speed pool pump?
19 of the 26 we hold, listed above cheapest-first within each verdict band, starting with the BLUETTI Elite 100 V2. The other 7 cannot run a variable-speed pool pump. Every one of those is a live calculation against that machine's own record, and opening a row shows the working.
