What it comes down to The only pump on this shelf that publishes a vacuum pressure — it stops itself at −0.02 MPa — and it claims ten days of freshness at half the price of the other electric pump here.
What the maker puts in writing
Electric, one click, stops automatically at −0.02 MPa
Up to 10 days of freshness
2 silicone stoppers
Lithium battery, Type-C charging
Food-grade materials
The only pressure on the shelf
Minus nought point nought two megapascals. Twenty kilopascals of depression, published, with the pump shutting off when it gets there.
Five other listings here describe an airtight seal. One of them says how airtight.
That number also lets a cross-comparison nothing else in this category allows: the HAGSCTA preserver on the aerator shelf of this site publishes −40 to −50 kPa, which is twice as deep.
Electric, for the price of manual
Sixteen dollars and ninety-nine cents, against sixteen and six cents for the cheapest manual Vacu Vin on this shelf.
Ninety-three cents is what it costs here to stop pumping by hand, and this is the pump that tells you where it stops.

What works, and what does not
Strengths
The only pump on this shelf with a published vacuum pressure, and it is the figure that defines what a vacuum pump does
Ten days of freshness claimed at half the price of the other electric pump here, which claims seven
Stops itself at a stated pressure, so the seal is neither guessed nor felt
Compromises
Minus 0.02 MPa is −20 kPa, half the depression the HAGSCTA aerator on the next shelf of this site publishes
Two stoppers against four on the dearer electric pump here
No bottles-per-charge figure and no neck diameter published
Its two closest on cost
Same shelf, nearest price — what the same spend buys instead.
Food grade, stated not to affect the wine’s flavor
Bottles per charge
Not stated by the maker
Neck diameter
Not stated by the maker
Seal confirmation
By automatic shut-off at the stated pressure

What readers ask us
What does −0.02 MPa mean?
A depression of 20 kilopascals below atmospheric. It is the only vacuum figure on this shelf, and it is what makes the auto-stop meaningful: the pump is not guessing, it is reaching a number. For comparison, the HAGSCTA preserver on the electric aerator shelf of this site publishes −40 to −50 kPa.
Is a deeper vacuum better?
For preservation, generally yes — less oxygen left in the bottle. Twenty kilopascals is a modest vacuum; the fact that this pump publishes it while five others publish nothing is still the more useful point, because it is the only figure in the category you can argue with.
Electric at this price — what is the catch?
Two stoppers rather than four, and no battery life published. The dearer electric pump on this shelf gives both and claims three fewer days of freshness.

Argon gas system · needle through the cork · confirmed on 4 EU markets
Coravin's mid-range gas-injection system, pouring through the original cork via a fine needle rather than a Pivot stopper. The identical ASIN and EAN are confirmed present on Amazon.de, .fr, .it and .es — though no live price was found on any of the four listings checked.
Best for: Someone who wants Coravin's gas-preservation approach but prefers pouring through the bottle's original cork rather than swapping it for a Pivot stopper.
Argon gas system · up to 4 weeks · includes aerator, 2 stoppers, 2 capsules
A gas-injection preservation system that pours through a Pivot stopper without removing the cork, keeping wine fresh for up to 4 weeks per Coravin's own claim. The bundle includes an aerator, two Pivot stoppers and two Pure argon capsules. Confirmed live with a real price on Amazon.fr.
Best for: Someone who regularly pours small amounts from expensive or special bottles over several weeks, and values the longer preservation window enough to justify the higher upfront cost and ongoing capsule expense.
A vacuum preservation pump bundled with two stoppers from Rabbit, a wine-tools brand distinct from Vacu Vin. Confirmed with a real price on the US Amazon listing; EU presence was not confirmed during research.
Best for: A US-based buyer wanting a stainless steel pump with two stoppers included from the outset, from a recognized bar-tools brand distinct from Vacu Vin.
