Cobalance CB-100 review

A single-bottle electric cooler holding any temperature from 41 to 64 °F for up to twenty-four hours.

What it comes down to Holds a single bottle anywhere between 41 and 64 °F for up to twenty-four hours, and it is the only product on this shelf that names a bottle it will not fit: Dom Pérignon.

What the maker puts in writing

  • One 750 ml bottle, 41 to 64 °F, held for up to 24 hours
  • Bottles under 3.74 in diameter
  • Fits Veuve Clicquot, Moët & Chandon, Louis Roederer
  • Does NOT fit Dom Pérignon or other wider or taller bottles
  • Freestanding or built in · LED flashes until temperature is reached

The exclusion is the best thing here

DOES NOT FIT Dom Pérignon or some other wider or taller bottles.

Eight products on this shelf. Seven say they fit most standard bottles. One names a bottle it rejects and gives the diameter that decides it.

For an object that physically grips a bottle, that sentence is worth more than any temperature range.

Holding, not chilling

Forty-one to sixty-four degrees, for twenty-four hours. That is the full span from a cold champagne to a cellar-temperature red, and it is held rather than reached quickly.

If the bottle starts warm, this shelf has two machines that take it to 43 °F in minutes, and they work by spraying ice water rather than by thermoelectrics.

What works, and what does not

Strengths

  • The only product on this shelf that names bottles it will not fit, and gives a diameter limit — under 3.74 inches
  • A published 41-to-64 °F range held for up to twenty-four hours, which covers champagne at 41 and a cellar red at 55
  • An LED that flashes until temperature is reached and then stays lit, so you know when to pour

Compromises

  • It holds; it does not chill. A warm bottle put in it is a warm bottle for a while — the Cooper Coolers here do 77 to 43 °F in minutes
  • One bottle at a time, and no wattage published
  • Named exclusions are useful, but "other wider or taller bottles" leaves the rest to measurement

Its two closest on cost

Same shelf, nearest price — what the same spend buys instead.

What readers ask us

Will it chill a warm bottle?

Slowly. This is a holding cooler: it reaches and maintains a set temperature and the LED tells you when. For a bottle that arrives warm and is wanted cold, the Cooper Coolers on this shelf publish minutes and this publishes hours.

Why does the Dom Pérignon exclusion matter?

Because champagne bottles vary more than wine bottles, and a cooler that grips a Veuve will not take a wider punt. This is the only listing on this shelf that names a brand it rejects — which is more useful than any of the "fits most bottles" claims around it.

Twenty-four hours — is that useful?

For an outdoor table or a long party, yes: it means one filling and no ice. It is the longest hold figure on this shelf; the frozen sleeve here claims hours and the insulated bucket claims longer than nothing.
