Two numbers decide whether a power station runs a laptop computer, and readers arrive using them interchangeably. Watts are the ceiling on what the inverter can hold at any instant — this load needs 5.2 W of them while it runs, and a 5,750 W spike lasting a few line cycles as it powers on — which is not the quantity a station's surge rating covers, and is not held against any verdict below. 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 machines in our library, 26 run it, 0 are a tight fit and 0 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.

What actually decides it
A switch-mode supply: milliseconds, not seconds
A switching power supply charges its input capacitors at the instant it is connected, which can be a large current — but it lasts a few line cycles, two orders of magnitude shorter than the second-scale event a station’s surge rating describes. The two are not the same quantity and this site does not hold that spike against a verdict. What decides the outcome here is the steady draw, and where the power factor is poor, the VA the inverter actually sees behind it.
How long the start-up actually lasts
The measured inrush here lasts around a hundredth of a second — a capacitor charging, not a motor starting. A station’s surge rating describes a second-scale event, so the two numbers are not comparable and this one is reported but never held against a verdict.
Which power stations run it
Every row is a live calculation against that machine's continuous output, surge ceiling and
inverter waveform. Of 26 machines, 26 run it, 0 are a tight fit and 0 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.

5.2 W while it is running, and 3.9–13 W across the models in this class, with 5,750 W demanded at the instant it starts. 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. The start-up figure here is the manufacturer’s own..
What size power station do I need for a laptop computer?
For a laptop computer, the EcoFlow RIVER 3 Plus (US 120 V) is the cheapest machine in our library that runs it, at 600 W continuous · 1,200 W surge ceiling and $259 against a running draw of 5.2 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. 26 of 26 machines clear it, 0 are a tight fit, and the tight ones are tight for reasons the list states individually.
How long will a power station run a laptop computer?
It depends entirely on the machine, which is the part most pages skip. Against 5.2 W of running draw, our figures put the BLUETTI Elite 30 V2 at about 17 h, and the BLUETTI Elite 100 V2 at about 54 h. Those hours come from usable-capacity figures derived from the manufacturers’ own published depth of discharge and inverter efficiency, 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: their brands publish nothing that makes a usable-capacity figure defensible, so those rows give an energy rate instead of a number we would have had to invent.
Does the start-up spike from a laptop computer matter?
Less than the number suggests, and this site says so rather than quietly using it. The start-up figure is published by the manufacturer for this device, so it describes the actual hardware rather than a category. The measured spike is 5,750 W, but it lasts a few line cycles — a capacitor charging, not a motor starting — while a station's surge rating describes a second-scale event. They are not the same quantity, so the spike is reported here and deliberately not held against any verdict above. A site that compared the two would fail this load against machines that run it perfectly well.
Which power stations run a laptop computer?
26 of the 26 we hold, listed above cheapest-first within each verdict band, starting with the EcoFlow RIVER 3 Plus. 0 more are a tight fit on a laptop computer — they run it, but with less headroom than we are willing to call comfortable — and 0 cannot. Every one of those is a live calculation against that machine's own record, and opening a row shows the working.
