Anova Precision Cooker Nano 2.0 AN400-EU00

You do not grill with a sous-vide stick. You clamp it to a pot of water, set a temperature, and it holds the bath at that value while the meat cooks in a sealed bag inside it. The crust only comes afterwards, in a pan or on the grate. Because of this second step, we list the stick in our grill accessories category, together with the Inkbird ISV-100W, the only other sous-vide stick there.

Nano instead of AN500: what is behind the Amazon link

The heading and product name of this page name the Anova Precision Cooker 2.0, and the product name also gives the model number AN500-EU00. The link, however, leads to ASIN B07QQSM8VD, and under that Amazon lists a device with the model and part number AN400-EU00. Its Amazon title begins with “Anova Präzisionskocher Nano 2.0 AN400-EU00”. At Anova this number is assigned unambiguously: AN400-EU00 is the version of the Anova Precision Cooker Nano with an EU plug (220 V). Anova does not use the suffix 2.0 for the Nano on its product page. In the shop too, none of the six sous-vide sticks from Anova has a 2.0 in its name; the AN500 is simply called Precision Cooker there.

The difference goes beyond the name. Anova gives the Nano 750 W and the AN500 1000 W. The AN500 connects to the app over Wi-Fi, the Nano over Bluetooth. The Amazon title does say “WiFi”, but the manufacturer says otherwise itself: on the page for the successor Nano 3.0, it says the Nano was switched from Bluetooth to dual-band Wi-Fi.

We therefore describe the Nano here, because that is what you get through the link. You could not have ordered an AN500 from Anova itself on 25 September 2026 either: in the manufacturer’s shop none of its variants was available, AN500-EU00 included. Of the Nano, only the US version was available there, at 149 US dollars, the same price as for every other plug variant. Anova does not say whether the Nano is being discontinued. It no longer appears on the “Meet the Anova Family” overview page, which lists only the Nano 3.0, Precision Cooker 3.0 and Pro.

Design, buttons, status light

The product image shows a black, round rod with the Anova lettering and a round display at the top. Below the digit display are minus, a start symbol and plus, with three small symbols above. A narrow blue strip glows on the shaft, and the cable lies in a loop beside it. Amazon lists the colour as black, silver.

Page 20 of the multilingual quick start guide labels ten parts in the German section. The buttons with thermometer, target and clock are called Aktuelle Temp. (current temp), Zieltemp. (target temp) and Timer, minus and plus decrease or increase temperature and time, with Start/Stopp in between; in addition there are the display, interface, clamp and plug. Anova support has a dedicated page for the status light. Steady white means: ready, but not in operation. Pulsing blue shows heating up, steady blue the target temperature reached, flashing red an error.

Anova gives the dimensions as 78 mm wide, 105 mm deep and 325 mm tall, and the weight as 0.63 kg. As material the manufacturer names plastic and stainless steel, without saying which part is made of what. According to Anova, the Nano can be stored in any kitchen drawer, right next to the whisk and ladle.

In detail: why the water bath sets the doneness

On the grate, a steak cooks over a heat that is far above its doneness point. You take it off when the core is right, and by then the edge is more cooked than the middle. In a water bath this gradient disappears, because the meat cannot get warmer than the water around it. If you set the stick to the core temperature of your desired doneness, the whole piece reaches exactly that value over time and stays there. Which value belongs to which doneness is in our core temperature chart.

That is why almost everything depends on the control. Anova gives the Nano an accuracy of ±0.1 °C and explains on the product page why that matters: for steak, only 3 °F lie between rare and medium rare, which is about 1.7 °C. The adjustable range is 0 to 92 °C. The display in the product image shows 130.0; given this upper limit, that can only be Fahrenheit. In Celsius it is 54.4 °C.

The second figure that matters is circulation, according to Anova 8 litres per minute. Without a pump the bath would stratify, because warm water rises, and a bag at the bottom of the pot could sit cooler than the spot where the stick measures. The flow mixes the water through so that the bag sees the same temperature as the stick.

The heating time can be estimated: one litre of water needs about 4.18 kJ per degree. Bringing ten litres from 15 to 55 °C therefore takes about 1.67 MJ or 0.46 kWh. With the Nano’s power that takes a good 37 minutes without any heat loss, with the AN500’s power just under 28. In a real pot the time is longer, because the pot wall and water surface give off heat, and it grows with the quantity: twice as much water, twice as long. Anova advises covering the vessel with a lid or foil; this shortens the heating time and saves energy.

Can the stick come outside to the grill?

No. Both safety lists in the German section of the quick start guide contain the same sentence: “Nicht im Freien verwenden” (do not use outdoors). Point 10 of the second list also keeps the device away from hot gas and electric hobs; you will find the exact wording further down. The side burner on a gas grill is therefore ruled out twice over.

The process that Anova describes separates kitchen and grill anyway. On the product page there are four steps: clamp the stick to your own pot, put the food in a sealed bag into the water, cook using the buttons or the app, and finally sear, in a pan or on the grill. On page 21, the quick start guide names only the pan for the last step: take the food out of the bag and sear it hot until it is crisp.

On the grate the meat then stays only until the surface is browned; it is already cooked. The hotter the zone, the shorter this phase and the narrower the edge that keeps cooking in the process. If you prefer to cook thick steaks entirely on the grill, you will find reverse searing with an indirect zone in our steak guide. It follows the same idea: first gently to core temperature, then short and hot.

What you need for the kitchen is listed on page 20 of the quick start guide: sealable bags, any pot and the food. You clamp the Nano to the side of the pot and fill water in until it stands between the MIN and MAX lines. Below 85 mm, according to Anova, sensors switch the stick off. A shallow roasting tin in which the water stands lower is therefore out of the question.

Bluetooth instead of Wi-Fi, app with subscription

You do not need a smartphone. According to Anova support, the Nano is built for operation with and without a phone, and you set time and temperature by hand at any time. With a phone, the connection runs over Bluetooth BLE 4.2, and the app is available for iOS and Android.

On the product page, Anova writes that you could follow the cook from other rooms of the house. Support is more cautious: Bluetooth has a limited range, and with strong interference from thick walls or plaster sometimes only 10 feet, around 3 m. If you light the grill in the garden while the meat sits in the bath indoors, the connection can therefore drop. From the office you will not reach the Nano at all.

The app is called Anova Culinary. According to the quick start guide, it contains thousands of recipes and sous-vide guides; according to the Amazon description, you create your own recipes and share them with the community under #anovafoodnerd. According to its own statement, Anova has offered connected cooking through this app since 2014.

New customers have paid a subscription for the app since 21 August 2024, 1.99 US dollars per month or 9.99 US dollars per year. Anyone who already had an account and the app before stays free of charge. What the subscription includes depends on the device, according to Anova; the subscription page gives cooking guides, notifications, recipe search and saving recipes as examples. How this looks for the Bluetooth Nano, whether the subscription applies in the EU in the same way and what it costs in euros, the page leaves open. The buttons on the device need neither app nor subscription.

Cleaning and the safety lists in the instructions

Deposits on the stick are normal according to Anova. They usually come from the minerals in tap water and can look brown, black or even green. Against this, support recommends a vinegar bath: water and white vinegar in equal parts in a small pot, put the Nano in, set 70 °C, and let it run for 30 minutes.

For the inside, Anova describes a second method and expressly recommends it if a bag burst during cooking. For this you fill water above the MIN line, add some washing-up liquid and let the Nano run at the same temperature for the same time.

You cannot remove the lower sleeve on the Nano, and anyone who pulls it off by force loses the warranty, according to Anova support. The bottom cap, however, does come off: turn it clockwise, and to put it back on turn it anticlockwise. Before that, points 5 and 14 of the second list below apply.

Both lists are on page 23 of the quick start guide. We reproduce them in full, because individual points picked out would give a false impression of what Anova requires. The first appears under the sentence “To reduce the risk of fire, electric shock or injury:” (translated from the German)

• Do not use with a damaged cable or plug.
• If the device does not work properly, has been dropped, has been damaged, has been left outdoors or has fallen into water, take it to a service point before use.
• Do not use outdoors.
• Disconnect the cable from the mains when not in use and before servicing.
• Do not use as a toy. When used by or near children, they must be supervised.
• Use only as described in these instructions. Use only accessories recommended by the manufacturer.
• Do not pull or carry the device by the cable, or use the cable as a handle.
• Do not use extension cables or sockets with insufficient current rating.
• Do not disconnect from the mains by pulling on the cable. To disconnect the device from the mains, pull the plug, not the cable.
• Do not touch the plug or device with wet hands.
• Do not insert objects into openings. Do not use with a blocked opening. Keep free of dust, lint, hair and any other objects that could impair the airflow.
• Do not use the device in flammable or inflammable liquids such as petrol or in areas where these may be present.
• Store the device indoors in a cool, dry place.

The second list is numbered and begins with “Always take basic safety precautions when using electrical appliances. These include:” (translated from the German)

1. Read all instructions. Including these instructions.
2. Do not touch hot surfaces.
3. To protect against electric shock, do not immerse the cable, plug or electrical components of the device in water or other liquids.
4. When used by or near children, they must be supervised.
5. Switch the device off and disconnect it from the mains when not in use and before any cleaning. Let the device cool down completely before assembling or disassembling.
6. Do not use devices with a damaged cable or plug! Do not operate the device if it malfunctions or has been damaged in any way. Contact Anova Support at support@anovaculinary.com for help.
7. The use of accessories is not recommended by the device manufacturer and can cause injury.
8. Do not use outdoors.
9. Do not let the cable hang over the edge of a table or counter. Do not let the cable come into contact with hot surfaces.
10. Do not place the device on or near a hot gas or electric hob or in a heated oven.
11. Be extremely careful when moving a device that contains hot liquids.
12. For operation, plug the plug into a wall socket. To disconnect, select “Stop” on the device interface or in the Anova Culinary app, then pull the plug from the wall socket.
13. Use the device only for its intended purpose.
14. Do not open the lower housing while the device is connected to the mains or in operation, because it contains heating elements and driven parts.
15. Do not use directly on a granite or marble surface. Always place an insulating layer between the hot pot and the granite or marble surface.

What Anova leaves open

For a purchase, one figure above all is missing: the maximum amount of water the Nano can heat. Anova gives the lower switch-off limit and the lines for minimum and maximum on the device, but no litre figure and no container size. Equally open remain the heating time for a given amount of water, the noise level, the cable length, the timer’s setting range, the material of the clamp and the scope of delivery; the quick start guide only shows what you have to add yourself. Whether parts may go in the dishwasher, and whether the Nano can cool a bath below the temperature of the water filled in, even though the stated range begins at freezing point, is answered by none of our sources. Country of origin, place of manufacture, an importer in the EU and a declaration of conformity are also missing; the warranty page gives only Anova Culinary, Inc. in San Francisco as an address. As documentation, Anova links a multilingual quick start guide with four German pages; we did not find a detailed German user manual. Anova does not say when the Nano came onto the market; Amazon gives 24 November 2022 as the release date for this listing.

Two details do not fit together. Amazon lists dimensions of 0.98 x 9.45 x 27.17 inches for the device. The 27.17 inches would be around 69 cm, more than double the height Anova gives, while the weight of 1.38 pounds matches the manufacturer’s figure. In addition, the quick start guide contradicts itself on accessories: the first list allows the accessories recommended by the manufacturer, point 7 of the second advises against accessories. Anova nevertheless sells a stand for the Nano in its own shop.

Correction note: An earlier version of this text described the stick with the power and Wi-Fi of the AN500, with a stainless steel housing, quiet operation and water baths of 20 to 30 litres, and it considered a brief rinse under running water sufficient. For the device behind this link, Anova documents none of this.

Three alternatives from our catalogue

Only one of them is also a sous-vide stick. The two cast iron pieces are here because they answer two other questions: whether you need a water bath at all, and what you sear in afterwards.

The prices are guide values from our data sheets and not current to the day; the price box on this page may differ. The rating is our editorial assessment from the data comparison. Whether the Inkbird controls as tightly in the water as the Nano is not answered by the table; for that, both would have to hang in the same pot.

When the Nano suits you and when it does not

The first question is where you cook. If you want to cook at the grill spot while the fire is burning, the Nano is out for the reasons given. For this case the Petromax Feuertopf is in the table: it controls nothing, but it may go in the embers.

Then the connection. If you want to see on your phone while out and about how far along the bath is, the Nano is ruled out. According to Inkbird, the Inkbird ISV-100W connects over 2.4 GHz Wi-Fi, and it has the lower guide price in our table. At Anova itself too, the Nano is the only one of the six sticks in the shop that has Bluetooth only; the other five connect over Wi-Fi.

Third, the amount of water. If several large pieces are often to go into the bath at the same time, our estimate from above speaks rather for more power. Anova has the Precision Cooker 3.0 with 1100 W for this and promotes it as heating medium to large water baths faster. An EU version of it, however, was not in stock in the Anova shop on 25 September 2026 either. If you only have shallow pots, the Nano 3.0, Precision Cooker and Precision Cooker 3.0 manage with a lower water depth than the Nano, according to Anova; the figures are in the questions below.

In terms of budget, more than the stick counts. You need bags, a pot with enough water depth and, for the crust, a pan or the grill; if you lack the pan, the Lodge L8SK3 is in the table. If you create your Anova account new and want to use the app with all its functions, the subscription comes on top.

The wrong choice is the Nano for anyone who cooks commercially, for example for catering or a snack stand. Anova’s warranty does not apply to commercial use, the only exception being the Precision Cooker Pro.
