magcheer 1-liter wide-mouth vacuum flask review

A 1 liter vacuum flask with a wide mouth stated to take ice, a screw lid with a vacuum seal, a carry handle and a non-slip silicone base — and no dimension behind any of it.

What this listing puts on record

A 1 liter black flask in stated 18/8 food-grade steel with double-wall vacuum insulation, a screw lid with a vacuum seal, a carry handle and a non-slip silicone base. All parts are stated dishwasher safe.

The mouth, which is the point of this one

The hub splits on this. A narrow mouth pours cleanly and loses less heat; a wide mouth takes ice, takes a brush and takes soup. This listing states it is wide, states it takes ice cubes, and states cleaning leaves no unreachable corners.

What it will not do is give the figure. No listing in this hub does, so wide and narrow remain words rather than a comparison.

The hours

24 hours cold, 12 hours hot — stated, with no conditions behind them, exactly as everywhere else here.

What it does not publish

No mouth diameter. No base diameter, despite a silicone base being a selling point. No empty weight, on a liter flask with a handle. No coating named behind sweat-resistant and several colors. No spare seal.

Before ordering

Wide-mouth flasks are harder to drink from while walking, and this one carries a liter. If you want one bottle for both drinking on the move and refilling with ice, that trade-off is the one to think about.

Availability

The American Amazon store was listing it at about $22 at the time of writing.

What it does well, and where it gives way

Strengths

  • A wide mouth stated to take ice cubes and to clean without trapping corners, which is the practical opposite of the narrow-mouth flasks here
  • All parts stated dishwasher safe, which is the cleanest maintenance claim in this hub
  • A carry handle and a non-slip silicone base, both stated, on a liter flask that is awkward without either

Compromises

  • Wide is a word and not a diameter, so whether your brush or your ice cubes actually fit is still unsettled
  • The vacuum seal in the lid is named and never offered as a spare part
  • No empty weight and no base diameter, on the larger of the two sizes this hub carries

What people ask before buying

How wide is the wide mouth?

The listing does not give a figure. It states the mouth takes ice cubes without difficulty and that cleaning has no hard-to-reach corners, which is a description rather than a dimension. No flask in this hub publishes a mouth diameter.

Does the whole lid go in the dishwasher?

The maker states all parts are dishwasher safe, which on a lid with a vacuum seal is a stronger claim than most listings here make. What it does not say is whether the seal should be taken out first, or where a replacement comes from.

Does magcheer say how its figures were measured?

No. Not published on the listing — no starting temperature, ambient temperature or fill level is given behind either figure. What the listing does publish instead is the finish: Black for this reference — stated in the title, with other colors offered; the coating is described only as sweat-resistant and is not named.

Our score

7.8/ 10

The wide-mouth liter of the hub, with the best cleaning story and the same blank line as everyone else where the diameter should be.

  • Highest Hot retention in the table: Thermos Stainless King SK2000 (18 hours — stated twice, in the bullets and in the description. It is the longest hot retention published on this shelf: the other fourteen listings claim 12 hours or less, and one European listing claims 13 hours of stability without separating hot from cold).

The buyer this one serves, among camping gear

A liter of iced drink where a wide mouth and a dishwasher-safe lid matter more than packing small.
