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.
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.
Against the rest of the camping gear
Close prices, same category: comparable camping gear. We keep only the specifications all of them publish, because a column with gaps compares nothing.

magcheer 1-liter wide-mouth vacuum flask
$22
1 liter — stated in the title
Double-wall vacuum insulation — stated
18/8 stainless steel — stated, described as food grade and non-toxic
32 oz — stated, about 950 ml, and stated in both the title and the bullets
Double-layered vacuum insulation — stated, with the bottle described as 100 per cent sweat free and free of condensation
18/8 of 304 stainless steel — stated, with non-toxic, BPA-free and phthalate-free claims. It is the only listing in this group to give the AISI number behind 18/8; on the European side one listing distinguishes SUS 201 outside from SUS 304 inside
Up to 12 hours — stated, with fresh taste claimed. The common figure on this shelf
16 oz — stated, about 470 ml, described as compact. The maker states that the Stainless King also comes in 40 oz and 68 oz. It is the second-smallest capacity in this group
Vacuum insulation — stated as the maker’s own technology, with the exterior stated to stay cool to the touch with hot drinks and sweat-free with cold. No layer count beyond the vacuum
18/8 stainless steel — stated as high quality, for the body and for the built-in cup
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
40 oz — stated, about 1.18 liters. The listing adds that 18, 24, 32, 40 and 64 oz versions exist, which confirms that capacity is a variant of one listing in this category rather than a separate product
Advanced vacuum insulation — stated, with no layer count. The word vacuum is used, which two listings on this shelf avoid
Not named. Food-grade stainless steel is stated, with resistance to rust, dents and odors, and no 18/8 or 304 figure. It is the only American listing in this group not to state 18/8
12 hours — stated. The common figure on this shelf
What separates the models, in camping gear
If price decides: Fanhaw 40 oz, three lids, at $12.
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.
Specifications: the manufacturer sheet for camping and hiking gear and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
500 ml · vacuum insulated · SUS 201 outside and SUS 304 inside · 24 h cold and 12 h hot stated · brushed finish · top handle
The only flask here that names a different steel for the inside and the outside, alongside a stated vacuum, both retention figures and a brushed finish.
Best for: A day out where a named inner steel, a stated vacuum and a dishwasher-safe body matter more than the hours quoted.
8 oz · TriMax triple insulation, the only triple-wall claim here · food-grade stainless, grade not named · 24 h stated once, hot and cold not separated · removable 3 oz silicone cup · folding hidden handle · dishwasher safe, flask and cup
The only triple-wall claim on this shelf, on an eight-ounce flask with a removable three-ounce silicone cup in its base — and a single 24-hour figure that does not separate hot from cold.
Best for: A hip-pocket flask for spirits or a single coffee, where two can share from one cup
