Hardware

Power (watts)

KitchenBoss G321: 1100 watts
KitchenBoss G300: 1100 watts
Below Avg Above
Rating
Generally, the higher the wattage, the more power. If you're looking to heat a lot of water, or want to have a sous vide that heats up quickly, this is an important factor for you to consider.

Voltage

KitchenBoss G321: 120v
KitchenBoss G300: 120v
Voltage is what makes electric charges move. But for this comparison, it's just important to note that appliances in the USA use 110-120v, while Europe uses 220–240v. Map for reference.

Hertz

KitchenBoss G321: Unknown
KitchenBoss G300: 60hz
Hertz is the frequency unit of the vibration cycle time. But, again, for this comparison, it's just important to note that USA uses 60hz, and Europe uses 50hz. Map for reference.

Height (in.)

KitchenBoss G321: 15 in.
KitchenBoss G300: 15 in.
Below Avg Above
Rating
The smaller the sous vide, the less space it takes up. However, size can sometimes come with a trade-off in power. We generally favor smaller sous vides over larger ones, because most people won't be cooking for a restaurant of people.

Tube Diameter (in.)

KitchenBoss G321: Unknown
KitchenBoss G300: 2.25 in.
Below Avg Above
Rating
The tube diameter determines how much space you have left in your pot or container for placing your food. We think a smaller diameter is better, as it gives you more space in your container to fit more food.

Weight (lbs.)

KitchenBoss G321: 2.8 lbs.
KitchenBoss G300: 3.3 lbs.
Below Avg Above
Rating
Weight is pretty self-explanatory. We think that the lighter the sous vide, the better.

Length of Power Cord (in.)

KitchenBoss G321: Unknown
KitchenBoss G300: Unknown
Below Avg Above
Rating
An often overlooked feature. The longer the cord, the more freedom you have to cook where you want to. And sometimes, there just isn't enough space around your outlet. Definitely keep the length of cord in mind when choosing the right sous vide for your kitchen.

Set Flow Direction Manually

KitchenBoss G321: Unknown
KitchenBoss G300: Unknown
Sous vides heat and circulate water around the cooking container. Most sous vides control the flow automatically, evenly heating the entire pot. However, some sous vides allow you to set the water flow direction manually, in case you've got an oddly shaped container. We think this is a small benefit, but overall, not super impactful.

360° Directional Pump

KitchenBoss G321: Yes
KitchenBoss G300: Yes
Below Avg Above
Rating
The 360° directional pump is a standard feature in most sous vides. Unlike the previous feature (manual flow direction), the 360° pump automatically circulates water in all directions, helping keep temperatures consistent throughout the container.

Maximum Temperature (°F)

KitchenBoss G321: 194°F
KitchenBoss G300: 194°F
Below Avg Above
Rating
Obviously, the higher the maximum temperature, the better. The more temperature range, the more you're able to cook. We also consider it an overall indicator of a sous vide's power.

Minimum Temperature (°F)

KitchenBoss G321: 104°F
KitchenBoss G300: 104°F
Below Avg Above
Rating
Much like the maximum temperature, the lower the minimum temperature, the better. As we stated before, the more temperature range, the more you're able to cook.

Temperature Setting (Smallest Increment °F)

KitchenBoss G321: 0.1°F
KitchenBoss G300: 0.2°F
Below Avg Above
Rating
The smaller the increment setting, the more precise you can be with your cooking. If a recipe says cook something at 153°, but you have a sous vide that can only select either 150° or 155°, it's going to be a bit disappointing. We definitely feel this is an important feature to consider.

Flow Rate/Pump (gallons/min.)

KitchenBoss G321: 5.3 gal/min.
KitchenBoss G300: 4.2 gal/min.
Below Avg Above
Rating
The flow rate is the amount of water that the sous vide can pump per minute. The more it can pump, the faster the container can heat and remain heated. Flow rate is another measure of sous vide strength.

Motor Speed (revolutions/min.)

KitchenBoss G321: 3800 rpm
KitchenBoss G300: 2900 rpm
Below Avg Above
Rating
Motor speed is how many revolutions per minute the sous vide's motor can spin. Much like flow rate, the motor speed is an indicator of the sous vide's strength. The faster, the better. However, it's important to note that most manufacturers don't measure their motor speed.

Max Water Capacity (gal.)

KitchenBoss G321: 13.2 gal.
KitchenBoss G300: 4 gal.
Below Avg Above
Rating
The max water capacity is the maximum amount recommended by the manufacturer. The higher the maximum, the more food you can cook, and the stronger the sous vide. So it goes without saying that the higher the capacity, the better the score.

Max. Water Line (in.)

KitchenBoss G321: Unknown
KitchenBoss G300: 5.5 in.
The max water line is the maximum height that water level can be on the sous vide heating tube. Think of it like a tea kettle: if you overfill it, when it boils, the water can come out of the pot. With the sous vide, if the water is too high, it can damage the machine. On it's on, this isn't a massive factor in scoring a sous vide, but it's something to keep in mind.

Min. Water Line (in.)

KitchenBoss G321: Unknown
KitchenBoss G300: 2.6 in.
Below Avg Above
Rating
The minimum water line is the opposite of the maximum water line. It's the area of the sous vide heating tube that must be covered by water. The lower the minimum line, the less water necessary for the sous vide to work. Generally, we think the lower the minimum line, the better.

Minimum Container Depth (in.)

KitchenBoss G321: Unknown
KitchenBoss G300: Unknown
Below Avg Above
Rating
Some sous vides are too large, or have a clamp that's too high, to fit on specific containers. This is where a minimum container depth comes into play. Generally, the smaller, the better, because you shouldn't be required to have giant containers to run the sous vide.

Noise Level (db.)

KitchenBoss G321: 15.5 db
KitchenBoss G300: 15.5 db
Below Avg Above
Rating
Noise level is somewhat important, as you don't want to be distracted by your sous vide cooking your food. Not many manufacturers measure the noise level, but for those that do, we wanted to include it. Here's a noise level reference.

Maximum Clamp Opening (in.)

KitchenBoss G321: Unknown
KitchenBoss G300: Unknown
Below Avg Above
Rating
The clamp which holds the sous vide in place on the container can open this amount of inches. This is especially important to note if the container(s) you plan on cooking in have thick walls or a lip/edge that's wide.

Adjustable Height Clamp

KitchenBoss G321: No
KitchenBoss G300: No
An adjustable height clamp allows you to choose how much of the heating tube goes into the water. This makes it much easier to get the correct water height on the sous vide heating tube.

Detachable Height Clamp

KitchenBoss G321: Yes
KitchenBoss G300: Yes
The height clamp is the piece on the side of the sous vide that keeps it attached to the container. When it's detachable, it makes it easier to clean and store.

Digital Display (LCD/LED)

KitchenBoss G321: Yes
KitchenBoss G300: Yes
A majority of sous vides have an LED/LCD screen, which let you interface with the machine. Some sous vides can only be operated via an LCD/LED screen, others only use an app, and some use both. We'd stick to finding a sous vide with a screen and an app if possible.

Manual Temperature Calibration

KitchenBoss G321: Unknown
KitchenBoss G300: Unknown
There are times where after a lot of use, the sous vide can be off by a few degrees from what the temperature reading says. With manual calibration, you can correct the machine to make sure it's accurate.

Built-in Refrigeration

KitchenBoss G321: No
KitchenBoss G300: No
With built-in refrigeration, you can place your food directly into the container in the morning (or whenever), and it'll keep it refrigerated until you've scheduled it to cook.

Removable Skirt / Bottom Cap

KitchenBoss G321: Yes
KitchenBoss G300: Yes
The skirt/cap is the bottom cover part of the sous vide. With a removable skirt/cap, you can more easily clean the sous vide. However, we don't know how often you'll need to clean the sous vide, as the only thing you'll be heating is water (unless a bag breaks or something).

Color

KitchenBoss G321: Silver
KitchenBoss G300: Silver
Color really comes down to preference. You'll basically be choosing between white, black, and metal.

Upper Tube Material (for Handling)

KitchenBoss G321: Plastic
KitchenBoss G300: Plastic
Below Avg Above
Rating
This is just a nice quality of life feature for your sous vide. Upper tubes that are made of metal feel nice to handle, and really give you the impression of a durable, quality sous vide.

Lower Tube Material (for Cooking)

KitchenBoss G321: Stainless Steel
KitchenBoss G300: Stainless Steel
Below Avg Above
Rating
The standard heating tube is stainless steel. We'd be highly cautious of purchasing any sous vide that doesn't have a heating tube that's stainless steel.

Max Single Cook Time (hrs.)

KitchenBoss G321: Unknown
KitchenBoss G300: 100 hrs.
Below Avg Above
Rating
For most cooking, this feature won't be super important. But in the event that you need to cook for a long time, the max single cook time lets you know how long the sous vide will stay on and cooking.

Water & Splash Resistance

KitchenBoss G321: IPX7
KitchenBoss G300: IPX7
Below Avg Above
Rating
The upper and lower halves of the sous vide have different purposes: the upper is for handling the sous vide, and the lower half goes in the water. But it's nice to have a sous vide which has a nice splash resistance. IP 67 is the best, IPX7 is second best.

Low Water-level Alarm

KitchenBoss G321: Unknown
KitchenBoss G300: Unknown
If there isn't enough water in the cooking container to cover the minimum water line on the heating tube, the sous vide will notify you with an alert/noise.

Low Water-level Shut-off

KitchenBoss G321: Unknown
KitchenBoss G300: Unknown
If there isn't enough water in the container to cover the minimum water line, the sous vide will automatically shut off. This is a nice protection feature for your sous vide.

Warranty (yrs.)

KitchenBoss G321: Unknown
KitchenBoss G300: 2 yrs.
Below Avg Above
Rating
The longer the warranty, the more belief the manufacturer has in their product. It's pretty self-explanatory, the longer the warranty, the better the score.

Manual Controls

KitchenBoss G321: Yes
KitchenBoss G300: Yes
Some sous vides operate only with an app, others only with buttons on the sous vide itself, and some with both buttons and app. We think it's nice to have manual controls as a backup if the app should somehow have issues.

Buttons

Can Operate in Celsius

KitchenBoss G321: Yes
KitchenBoss G300: Yes
Important for those those who get a lot of recipes from foreign countries, operating in Celsius is a great quality of life feature.

Alert Sounds (Beeping, etc.)

KitchenBoss G321: Yes
KitchenBoss G300: Yes
Alert sounds are a nice quality feature to consider when purchasing a sous vide. The feedback noises are appreciated whether it's just pressing buttons on the interface, alerting you to a problematic water level, or even just when your food has finished cooking.

Has Timer

KitchenBoss G321: Yes
KitchenBoss G300: Yes
A basic, necessary component of any sous vide. Most sous vides have a built-in timer. And if it doesn't have one, it's a bit questionable.

Delay Timer/Scheduling

KitchenBoss G321: Yes
KitchenBoss G300: No
Some sous vides will let you set a delay on the timer start. This means you can prep your meal before work and set the sous vide to start start cooking an hour before you get home. It's a great additional feature to have.

Time Setting (Smallest interval)

KitchenBoss G321: 1min
KitchenBoss G300: 1min
Below Avg Above
Rating
Some recipes require short, specific amounts of time cooking. The time interval setting is quite valuable for these types of recipes. Most sous vides have 1min or 5min interval.

Automatic Shut-down (when timer ends)

KitchenBoss G321: Yes
KitchenBoss G300: Unknown
Some sous vides have an automatic shutdown when the timer ends. It's a super handy feature in the event that you forget about the timer or something takes you away from the kitchen. It can save you on the electricity bill and putting unnecessary hours on the machine.

Connection

KitchenBoss G321: No
KitchenBoss G300: No
Below Avg Above
Rating
Connections lets you know whether or not the sous vide has Bluetooth, WiFi, both, or neither. When a sous vide has the connection feature, it allows you to control your sous vide from outside the kitchen.
