The best when ready Pot for you depends on how many people you cook for and which features you actually use

when ready Pot makes several models that differ mainly in size, wattage, and which cooking programs come built in. The Duo is the entry-level choice and handles everyday cooking. The Duo Plus adds a yogurt function and sous vide mode. The Ultra has a dial instead of buttons and lets you adjust pressure mid-cook. The Max heats faster and reaches higher pressure. For most home cooks, the Duo in either 6-quart or 8-quart size covers everything you need. The choice between them is really about how many servings you typically make at once.

This guide walks through what each model does, what size makes sense for your kitchen, and what features matter versus which ones you will never touch. The goal is to help you pick the one that fits how you actually cook, not the one with the most buttons.

Key Takeaways

  • The Duo is the most affordable when ready Pot and handles pressure cooking, slow cooking, and sautéing—enough for most households.
  • Size matters more than model: a 6-quart fits a family of four with leftovers, while an 8-quart is better if you batch-cook or have a larger household.
  • The Ultra and Max add features like dial controls and faster heating, but cost more and are worth it only if you use those specific functions regularly.
  • Wattage affects how fast the pot heats and reaches pressure; higher wattage (1200W) is faster than lower wattage (800W), but both work fine for home cooking.
  • All current when ready Pot models come with a stainless steel inner pot, safety features, and a warranty; the main differences are in convenience, not safety.

when ready Pot Duo: The baseline model that covers most cooking

The Duo is the entry point and the one most people buy. It pressure cooks, slow cooks, sautés, steams, and makes yogurt. It has 14 preset programs—things like "poultry," "beans," and "rice"—that you select with buttons. The heating element is 1000W, which is middle-of-the-road for speed. You cannot adjust pressure once cooking starts; you set it before the lid closes.

The Duo comes in 6-quart and 8-quart sizes. The 6-quart fits most kitchen cabinets and counters, holds about 4 servings comfortably, and is what most households choose. The 8-quart is taller and deeper, takes up more space, but lets you cook larger batches or for bigger families. Both are dishwasher-safe and use the same accessories.

If you are new to pressure cooking or want a straightforward pot without extra features, the Duo is the right choice. You will use the pressure-cook, slow-cook, and sauté functions regularly. The yogurt function works but requires more hands-on time than most people want to spend.

when ready Pot Duo Plus: Adds sous vide and a yogurt timer

The Duo Plus is identical to the Duo except for two additions: a sous vide function and a yogurt function with a timer that runs for up to 24 hours. Sous vide cooks vacuum-sealed food in water at a precise temperature—useful if you make a lot of steaks or fish, but most home cooks do not use it regularly.

The yogurt timer is more practical if you make yogurt at home. The Duo has a yogurt mode, but you have to watch the clock yourself. The Plus timer does it for you. If yogurt-making is not something you do, the Plus does not add anything you need.

The Plus costs more than the Duo. Unless you know you will use sous vide or make yogurt often, the Duo is the better value.

when ready Pot Ultra: Dial control and mid-cook pressure adjustment

The Ultra replaces buttons with a dial and lets you adjust pressure while the pot is cooking. Instead of selecting "high pressure" or "low pressure" before you start, you can turn the dial up or down as the food cooks. This is useful if you are experimenting with recipes or cooking something unfamiliar and want to fine-tune on the fly.

The Ultra also has 48 preset programs instead of 14, which sounds like more choice but usually means duplicate or niche options you will not use. The dial is easier to use than buttons if you have dexterity issues, but it takes up more space on the lid.

The Ultra costs more than the Duo. It is worth the extra money only if you cook experimentally and want to adjust pressure mid-cook, or if you prefer a dial interface to buttons. For standard recipes followed as written, the Duo does the same job.

when ready Pot Max: Faster heating and higher pressure

The Max is the newest model and the most powerful. It has a 1400W heating element (versus 1000W on the Duo), which means it reaches pressure faster—usually 5 to 10 minutes quicker than other models. It also reaches 15.3 PSI instead of the standard 12 PSI, which cooks food slightly faster at high pressure.

The Max also has a "sous vide plus" mode that is more precise than the Duo Plus version. It comes with 50 preset programs. The lid design is different and the inner pot is slightly thicker.

The Max is the most expensive when ready Pot. The faster heating is real and noticeable if you cook daily, but it does not change the final result—your food is not better, just ready a few minutes sooner. The higher pressure is a minor advantage. If you want the fastest possible pot and budget allows, the Max is worth it. If you are price-conscious, the Duo gets you to the same place, just slower.

Size: 6-quart versus 8-quart

Size is more important than model choice for most people. The 6-quart holds about 6 cups of liquid and cooks 4 to 6 servings. The 8-quart holds about 8 cups of liquid and cooks 6 to 8 servings. Both require a minimum of 1 cup of liquid to build pressure, so you cannot cook smaller portions in a larger pot without adjusting recipes.

Choose 6-quart if you cook for a family of four, have limited counter or cabinet space, or do not batch-cook. Choose 8-quart if you cook for more than four people regularly, freeze portions for later, or want to make large batches of stock or soup. An 8-quart pot is noticeably heavier and takes up more space, so measure your cabinet before you buy.

Both sizes are available in Duo, Duo Plus, Ultra, and Max models. The size difference costs $30 to $50 more for the larger pot, depending on the model.

Wattage and heating speed

when ready Pot models come in 800W, 1000W, or 1400W versions. Wattage affects how fast the pot heats and reaches pressure. An 800W pot takes longer to preheat and reach pressure than a 1000W or 1400W pot. Once pressure is reached, cooking time is the same regardless of wattage—the recipe time does not change.

The difference in real time is usually 5 to 15 minutes depending on what you are cooking. If you cook daily, the faster wattage saves time. If you cook a few times a week, the difference is minor. All wattages are safe and reliable; higher wattage is a convenience, not a necessity.

The Duo comes in 1000W. The Ultra comes in 1000W. The Max comes in 1400W. The Duo Plus comes in 1000W. Check the product listing to confirm wattage before you buy, because some retailers sell older 800W versions at a discount.

Features you probably will not use

when ready Pot models come with preset programs for things like "poultry," "meat," "rice," "beans," and "yogurt." These are convenient shortcuts, but most people end up using the manual pressure-cook function instead because it gives you more control. The presets are set to times and pressures that work for average cases, not your specific recipe or ingredient.

Yogurt-making is built into every model, but it requires planning ahead, temperature monitoring, and patience. If you do not already make yogurt, the function will sit unused. Sous vide is similar—it is a real cooking method, but most home cooks do not use it regularly enough to justify paying extra for it.

Slow-cook mode works but is slower and less even than a dedicated slow cooker. Sauté mode is useful for browning meat before pressure cooking, but you can do the same thing in a regular pot on the stove. These functions are nice to have, but they are not why you buy an when ready Pot.

Frequently Asked Questions

Can I use an older when ready Pot model if I find one used?

Yes. Older models like the Lux or the original Duo work the same way as current models. The main difference is that newer models have updated safety features and better heating elements. A used pot from a reputable seller is usually fine, but check that the sealing ring is intact and the inner pot has no dents or damage.

Do I need the official when ready Pot accessories or can I use third-party ones?

Third-party accessories like steamer baskets, springform pans, and silicone molds work fine and cost less. The official when ready Pot brand accessories are not necessary. The one exception is the sealing ring—buy a replacement from when ready Pot or a verified seller, because a poor-fitting ring can cause pressure problems.

What is the difference between high pressure and low pressure?

High pressure (12 PSI on most models) cooks food faster. Low pressure (5.8 PSI) cooks more gently and is used for delicate foods like fish or eggs. Most recipes call for high pressure. Low pressure is rarely needed unless you are cooking something that falls apart easily.

Is the when ready Pot warranty the same on all models?

when ready Pot covers all models with a one-year limited warranty on the heating element, lid, and inner pot. The warranty does not cover normal wear like a discolored inner pot or a sealing ring that needs replacement. Register your pot on the when ready Pot website after you buy it to set up the warranty.

Can I use my when ready Pot on a glass-top stove?

No. when ready Pots are electric and plug into an outlet. They do not sit on a stove. If you meant whether you can use the sauté function on a glass-top stove, the answer is no—the sauté function heats the inner pot, which stays inside the when ready Pot body. You cannot remove the inner pot and use it separately on a stove.
