Ninja: the kitchen brand behind the air fryer boom, and how to choose yours

Ninja is the brand that turned the air fryer from a niche gadget into something half the country seems to own. But air fryers are only part of the story. The brand started with blenders, and it now makes kettles, choppers, multi-cookers, ice cream makers and portable blenders, all built around the same idea: take a kitchen job people find fiddly and make it quicker.

We sell five Ninja products at Clean Smile Home. None of them is an air fryer, as it happens. We chose a temperature control kettle, a mini chopper, a personal blender, a cordless blender you can take to the gym, and a multi-cooker that sears and slow cooks in the same pot. Between them, they cover a lot of what Ninja does best.

This guide covers Ninja's history, what the brand is good at and where it falls short, each of the five products in detail, a guide to choosing between them, recipes and ideas to get you started, and care tips so they keep working for years.

The short version

• Ninja is owned by SharkNinja, the same company that makes Shark vacuums and steam mops. The Ninja brand launched in 2009 with blenders.
• It's strongest on clever, powerful kitchen appliances at mid-range prices. It's less suited to people who want minimal, single-purpose tools or very simple controls.
• For tea and coffee at the right temperature, buy the Ninja Perfect Temperature Kettle KT200UK.
• For chopping onions, herbs and nuts in seconds, buy the Ninja Professional Stackable Chopper NJ1002UKBK.
• For smoothies at home, buy the Nutri Ninja QB3001UKS. For smoothies on the move without a plug, buy the Ninja Blast BC151UKBK.
• For stews, curries, chilli, rice and one-pot dinners, buy the Ninja Foodi PossibleCooker MC1101UK.

Where Ninja came from

The company behind it

Ninja belongs to SharkNinja, a company founded in Montreal in the mid-1990s by Mark Rosenzweig. It was originally called Euro-Pro and made steam cleaners and vacuum cleaners. In 2003 it moved its headquarters to Massachusetts in the United States.

The company launched the Shark brand for cleaning in 2007. Then in 2009 it launched Ninja for the kitchen. The first Ninja products were blenders, and blending is still at the heart of the brand. In 2015, the company renamed itself SharkNinja after its two brands, and Ninja released its first coffee maker the same year.

From blenders to everything

Over the following decade, Ninja added food processors, multi-cookers, air fryers, grills, ice cream makers, kettles and portable blenders. The Foodi name, which you'll see on the PossibleCooker we sell, arrived in 2018 for Ninja's multi-function cooking appliances.

In Britain, the brand took off. SharkNinja registered a UK company in 2013 and its European business is registered in Leeds. In January 2024, Marketing Week described a "social media-inspired boom" in Ninja air fryers as one of the main reasons for the company's growth. If you've watched someone on TikTok make crispy chicken wings in an air fryer, there's a fair chance it was a Ninja.

In July 2023 SharkNinja became a standalone company on the New York Stock Exchange. It reported more than $4.3 billion in net sales for 2023 and holds more than 4,500 patents.

How Ninja designs things

SharkNinja talks a lot about "consumer insight". In plain English, Ninja watches how people cook, spots what annoys them and designs around it. A kettle that holds water at 80°C so your green tea doesn't taste bitter. A chopper with bowls that stack so leftovers go straight in the fridge. A slow cooker pot you can sear in, so you don't have to brown meat in a separate pan and wash up twice.

Not every Ninja feature is something you'll use. But most products have at least one detail that makes a real difference day to day.

What Ninja does well, and where it doesn't

Strengths

Power. Ninja blenders and choppers tend to have strong motors and sharp blades for their size. The Nutri Ninja handles ice and whole fruit, and the Blast handles frozen fruit even without a cable.

Cutting down washing up. Blend in the cup you drink from. Sear and slow cook in one pot. Store leftovers in the bowl you chopped them in. This is a pattern across the range.

Features that are actually useful. Temperature presets on the kettle, a Hold Temp function, stackable bowls, a pot that goes in the oven. These aren't gimmicks.

Dishwasher-safe parts. Most removable parts across our Ninja range can go in the dishwasher. Check each product's manual for specifics.

Where Ninja isn't the right pick

If you want the simplest possible kettle. The Ninja kettle has a display and buttons. If all you want is boiling water, a standard kettle from Russell Hobbs or Tower is cheaper and simpler.

If you want a full-size food processor. The Stackable Chopper is for small jobs. It won't slice, grate or knead dough.

If you're short on cupboard space and already own similar gadgets. Ninja makes a lot of products that overlap. Buy for the jobs you do every week, not the ones you might do once.

If you need a pressure cooker. The PossibleCooker sears, slow cooks, steams and cooks rice and pasta, but it doesn't pressure cook. For that, see the Instant Pot Classic Mini.

The Ninja range at Clean Smile Home

Ninja Perfect Temperature Kettle 1.7L KT200UK, black

The KT200UK is a temperature control kettle in matte black. Instead of just boiling water, it heats to the temperature you choose.

What it does:

• Six presets: 60, 70, 80, 90, 95 and 100°C.
• A manual setting from 40 to 100°C in 5 degree steps.
• Hold Temp keeps water at your chosen temperature for up to 30 minutes.
• A digital display shows the live water temperature as it heats.
• 3000 W, with one cup in under 50 seconds by Ninja's figures.
• 1.7 litre capacity, lit water window, removable anti-scale filter, 360-degree base and boil-dry protection.
• A drinks guide with a temperature chart comes in the box.

Who it's for: green and white tea drinkers, people who brew coffee with a cafetière, pour-over or AeroPress, and anyone who finds their tea or coffee often tastes bitter.

Why temperature matters: boiling water is too hot for delicate teas and for most coffee. Green tea brewed at 100°C tends to taste bitter and grassy. Brew it at around 70 to 80°C and it's much smoother. Coffee is usually best somewhere around 90 to 96°C. A temperature kettle takes the guesswork out.

Worth knowing: the Hold Temp function is handy if you drink several cups through a morning, but don't use it for baby feeds without following NHS advice on making up formula (more on that in the FAQ). Read our full guide: Ninja Perfect Temperature Kettle KT200UK: better coffee and more control.

Ninja Professional Stackable Chopper 200W NJ1002UKBK, black

The Stackable Chopper is a compact 200 W chopper for the small, repetitive jobs that take ages with a knife.

What it does:

• A 200 W power pod with pulse control, so you choose how fine the chop is.
• Two 500 ml bowls that stack together for storage.
• Chops, minces, grinds and blends.
• Lids that double as storage lids, so you can chop, cover and refrigerate.
• BPA-free, dishwasher-safe removable parts.

Who it's for: anyone who cries chopping onions, cooks from scratch a few times a week, makes dips, pesto or salsa, or wants to batch-prep garlic, ginger and herbs.

Worth knowing: it's a chopper, not a food processor. It's brilliant for small amounts, but large quantities need doing in batches. Pulse rather than hold the button, or onions turn to purée. See Ninja Stackable Chopper NJ1002UKBK: 7 quick jobs for a mini chopper for ideas.

Nutri Ninja 700W Slim Blender and Smoothie Maker QB3001UKS

The Nutri Ninja is a slim personal blender that blends straight into the cup you drink from.

What it does:

• 700 W of power.
• Pro Extractor Blades that handle whole fruit, vegetables, seeds and ice.
• Two 470 ml cups with spout lids for drinking on the go.
• Non-slip feet and BPA-free, dishwasher-safe parts.
• A recipe guide in the box.

Who it's for: anyone who wants a quick breakfast smoothie, a protein shake after training or a single-portion soup or sauce, without dragging out a big jug blender.

Worth knowing: it needs to be plugged in. If you want to blend away from a socket, at work or the gym, look at the Ninja Blast below. Read Smoothies in one cup: getting started with the Nutri Ninja QB3001UKS.

Ninja Blast Cordless Portable Blender BC151UKBK, black

The Ninja Blast is a cordless blender. Charge it by USB-C, then blend wherever you are.

What it does:

• Rechargeable by USB-C, with 10 or more blends per charge and about two hours for a full charge.
• A stainless steel BlastBlade that handles ice and frozen fruit.
• A 530 ml cup (470 ml maximum fill).
• A leak-proof sip lid with a carry handle.
• One-touch control.
• A BPA-free cup and lid that are dishwasher safe.

Who it's for: gym-goers, office workers, students, campers, people with small kitchens and anyone who likes a fresh smoothie away from home.

Worth knowing: it's powerful for a cordless blender, but it won't match a mains blender on very thick mixtures. Add liquid first and keep frozen fruit to a sensible amount. The motor base shouldn't go in water or the dishwasher; wipe it clean. See Ninja Blast cordless blender: smoothies at the gym, office or campsite.

Ninja Foodi 8-in-1 PossibleCooker 6L MC1101UK

The PossibleCooker is a 6 litre multi-cooker built around one big idea: brown, sear and slow cook in the same pot.

What it does:

• Eight functions: sear/sauté, slow cook, white rice, brown rice, pasta, porridge, steam and keep warm.
• A 6 litre non-stick pot that's oven-safe to 240°C, so you can finish a dish in the oven or keep it warm there.
• Up to 12 hours of slow cooking and 12 hours of keep warm.
• 1400 W.
• A dishwasher-safe pot, lid and accessories.
• In the box: the pot, a glass lid, a steam rack, a measuring cup, a rice spoon and a recipe guide.

Who it's for: families, batch cooks, anyone who loves stews, curries and chilli, and anyone who's given up on their old slow cooker because browning meat in a frying pan first felt like too much washing up.

Worth knowing: it isn't a pressure cooker or an air fryer. It's a very good slow cooker that also does the jobs of a frying pan, a rice cooker and a steamer. Read Sear, slow cook and serve from one pot: the Ninja Foodi PossibleCooker MC1101UK.

Which Ninja should you buy?

Ninja makes so much that it's easy to want everything. Start with how you actually eat and drink.

"I drink a lot of tea or coffee"

The KT200UK kettle. You'll use it several times a day, every day, which makes it the best value per use in the whole range.

"I cook from scratch but hate the prep"

The Stackable Chopper. It takes the sting out of onions and the faff out of garlic and herbs.

"I want a quick, healthy breakfast"

The Nutri Ninja if you blend at home, the Ninja Blast if you'd rather blend at work or the gym.

"I want dinner ready when I get home"

The PossibleCooker. Sear in the morning, set it to slow cook, and come home to a meal.

"I'm setting up a first kitchen"

Start with the kettle and the chopper. They're the two you'll use most often. Add the PossibleCooker when you want to batch cook.

Nutri Ninja or Ninja Blast?

This is the question we get asked most about Ninja, so it gets its own section.

	Nutri Ninja QB3001UKS	Ninja Blast BC151UKBK
Power	700 W mains	Rechargeable battery (USB-C)
Cups	2 x 470 ml with spout lids	1 x 530 ml (470 ml max fill) with sip lid
Ice and frozen fruit	Yes, with ease	Yes, in sensible amounts with enough liquid
Use away from a socket	No	Yes
Best for	Thicker smoothies, nut butters in small amounts, shakes for two	Single smoothies at the gym, office or on holiday

Short answer: if you blend at home, the Nutri Ninja is more powerful and gives you two cups. If you want freedom from the plug, the Blast is the one. Some people own both: the Nutri Ninja for the weekend batch, the Blast for the gym bag.

Getting started: ideas for each product

Kettle temperatures cheat sheet

• Green tea: about 70 to 80°C. Steep for two to three minutes.
• White tea: about 80°C.
• Oolong: about 90°C.
• Black tea and builder's tea: 100°C.
• Herbal and fruit teas: 100°C.
• Cafetière and pour-over coffee: about 90 to 95°C.
• Instant coffee: many people prefer 80 to 90°C, which avoids a scorched taste.

These are starting points. Adjust to taste, and check the guidance on your tea or coffee pack.

Better cafetière coffee, step by step

A cafetière (or French press) is the easiest way to make proper coffee at home, and it's where a temperature kettle makes the most noticeable difference.

1. Set the KT200UK to 95°C, or to 90°C if you find your coffee tastes harsh.
2. While the water heats, warm the cafetière with a splash of hot tap water and pour it away.
3. Add coarse ground coffee. A common starting point is about 60 g of coffee per litre of water, or roughly a level tablespoon per mug. Adjust to taste.
4. Pour in a little water, just enough to wet the grounds, and wait about 30 seconds. This lets gases escape so the coffee extracts evenly.
5. Pour in the rest of the water, stir gently and put the lid on with the plunger up.
6. Wait about four minutes, then press the plunger down slowly.
7. Pour straight away. Coffee left sitting on the grounds turns bitter.

Pour-over basics

Pour-over (using a cone dripper and paper filter) rewards control. Set the kettle to around 93 to 96°C. Rinse the paper filter with hot water first to remove any papery taste. Use a medium-fine grind, wet the grounds first and wait 30 seconds, then pour slowly in circles. The KT200UK's Hold Temp is useful here because you can take your time without the water cooling.

Green tea that doesn't taste bitter

If you've given up on green tea because it always tastes harsh, try this before you give up for good. Set the kettle to 70 or 80°C. Use slightly less tea than you think. Steep for two minutes, taste, and only go longer if it's too weak. Take the leaves or bag out as soon as it's right. Most bitter green tea is a result of water that's too hot and steeping that's too long, not bad tea.

Chopper, knife or food processor?

A sharp knife is still the best tool for slicing, for neat dice and for one onion. A mini chopper wins when you want small pieces of several things at once, when you're doing garlic, ginger or herbs, or when you're making a dip or paste. A full food processor wins for big quantities, slicing and grating, and kneading dough.

Most home cooks get the biggest benefit from a knife plus a mini chopper. A full food processor is worth adding if you regularly cook for a crowd or bake bread.

Five quick jobs for the chopper

1. Onion, carrot and celery for a soffritto base, in seconds.
2. Garlic and ginger paste for curries. Make a batch and store it in the second bowl in the fridge.
3. Fresh pesto: basil, pine nuts, garlic, parmesan and olive oil.
4. Salsa: tomatoes, red onion, chilli, coriander and lime. Pulse gently so it stays chunky.
5. Breadcrumbs from stale bread, for coatings and stuffing.

A simple smoothie formula

Rather than follow a recipe, use this pattern and swap ingredients for what you have:

• Liquid first: milk, plant milk, juice or water, about a third of the cup.
• A soft fruit: banana, mango or berries.
• Something green if you like: a handful of spinach barely changes the taste.
• Something thick: yoghurt, oats or a spoon of nut butter.
• Ice or frozen fruit last, if you want it cold.

Never fill past the max line. Liquid at the bottom helps the blades move everything else.

Three easy PossibleCooker dinners

1. Beef chilli: sear mince with onion and garlic on the sear setting, add spices, tinned tomatoes, kidney beans and stock, then slow cook. Use the rice function another day, or cook rice separately.
2. Chicken curry: brown chicken thighs, add onion, curry paste, coconut milk and chopped tomatoes, then slow cook until tender.
3. Overnight porridge: use the porridge function with oats and milk for a hot breakfast.

Always check meat is cooked through before serving. With chicken and pork, there should be no pink meat and the juices should run clear.

Slow cooking for beginners

If the PossibleCooker is your first slow cooker, these basics will save you from the two classic disappointments: watery stews and dry meat.

Use less liquid than you think

A slow cooker has a lid that traps steam, so almost nothing evaporates. Liquid you add at the start is still there at the end, plus the juices that come out of the meat and vegetables. A recipe written for a hob or oven usually needs less stock in a slow cooker. As a rough guide, the liquid should come about halfway up the ingredients, not cover them.

Brown first, then slow cook

This is the PossibleCooker's main advantage. Searing meat and softening onions before slow cooking adds a lot of flavour. In most slow cookers it means using a separate frying pan. In the PossibleCooker you use the sear setting in the same pot, then switch to slow cook.

Choose the right cuts

Slow cooking suits cheaper, tougher cuts with connective tissue: beef shin, chuck or brisket, lamb shoulder, pork shoulder, chicken thighs. They turn soft and tender over hours. Lean cuts like chicken breast or pork tenderloin dry out if cooked too long, so add them later or use a shorter cook.

Don't keep lifting the lid

Every time you lift the lid, heat escapes and it takes a while to recover. Lift it only when you need to.

Don't put frozen meat in a slow cooker

Thaw meat fully in the fridge first. Frozen meat can spend too long at temperatures where bacteria grow before the pot heats up. This is standard food safety advice for all slow cookers.

Thicken at the end

If a stew is too thin, take the lid off and use the sear setting for a few minutes to reduce it, or stir in a little cornflour mixed with cold water.

A week of batch cooking with Ninja

Here's a simple plan using the PossibleCooker and the chopper together. It's designed for a household of three or four, but it scales down easily.

Sunday: prep and cook

• Use the chopper to prepare a big batch of onion, carrot and celery. Use one bowl for today's cooking and put the second bowl, with its lid on, in the fridge.
• Make a large beef or vegetable chilli in the PossibleCooker. Sear, add everything, slow cook through the afternoon.
• Portion half for tonight and freeze the rest in labelled containers.

Tuesday: curry

• Use the chopped base from the fridge, plus garlic and ginger blitzed in the chopper.
• Brown chicken thighs on the sear setting, add the base, curry paste and tinned tomatoes, then slow cook during the day.

Thursday: rice and steamed veg

• Use the white rice function, then steam vegetables on the rack.
• Serve with leftover curry or defrosted chilli.

Every morning: smoothies

• Bag up smoothie packs on Sunday: fruit, spinach and oats in freezer bags.
• Tip a pack into the Nutri Ninja or Ninja Blast cup, add milk or water, and blend.

The point isn't to follow this exactly. It's that the Ninja products work well together. The chopper feeds the cooker, and the blenders take care of breakfast.

Common smoothie mistakes

• Too little liquid. The blades spin in a pocket of air and nothing moves. Add liquid first, then the rest.
• Overfilling. Personal blender cups need space for things to move. Stay below the max line.
• Only frozen fruit. Mix frozen with fresh, or add a little yoghurt, so it's thick but still blends.
• Big chunks of hard veg. Raw carrot and beetroot blend better if you grate or chop them small first.
• Leaving the cup to dry. Rinse straight after. Dried banana and berries stick like glue.

Why Ninja caught on in British kitchens

It's worth thinking about why a brand that only arrived here in the 2010s became so popular so quickly. We think a few things came together.

First, British kitchens are often small. Appliances that do several jobs, or that stack, or that let you blend in the cup you drink from, make sense when worktop space is tight.

Second, a lot of people want to cook more from scratch but don't have much time on weeknights. Choppers and slow cookers make that easier.

Third, Ninja got very good at showing people what its products do. Short videos of food going in and coming out crispy, smooth or tender made the products easy to understand. Marketing Week tied the brand's air fryer boom directly to social media.

And finally, the products are generally good. Hype gets people to buy once. It doesn't get them to recommend a product to friends. Ninja's popularity has lasted because the products do what they say.

Safety with Ninja appliances

• Blades are very sharp. Handle the blade assemblies by the plastic parts and wash them carefully.
• Never put your hand or a utensil into a blender or chopper while it's connected to power.
• Don't blend hot food in sealed cups. Let it cool first.
• Keep the PossibleCooker away from the edge of the worktop and keep the lead tucked in. The outside and lid get hot during cooking.
• Use oven gloves when lifting the hot pot.
• Keep the kettle's MAX and MIN lines in mind, and keep cords out of reach of children.

How to look after your Ninja appliances

The kettle

• Descale regularly with a kettle descaler, or a citric acid or vinegar solution, then rinse well. Once a month in hard water areas, every two to three months in soft water areas.
• Wash the anti-scale filter every few weeks.
• Wipe the outside with a soft damp cloth. Keep the base and its controls dry.

The chopper and blenders

• Rinse cups, bowls and blades straight after use, before food dries on.
• For a quick clean, half-fill the cup or bowl with warm water and a drop of washing-up liquid and pulse it for a few seconds, then rinse.
• Handle blades carefully. They're very sharp. Hold them by the plastic part.
• Never put the motor base or power pod in water. Wipe it with a damp cloth.
• Let parts dry fully before storing, especially seals and lids, so they don't smell.

The Ninja Blast battery

• Charge it with a USB-C cable and a suitable charger.
• Don't leave it in a hot car or a freezing shed.
• Top it up before long storage rather than leaving it flat.

The PossibleCooker

• Use wooden or silicone utensils on the non-stick pot. Metal can scratch the coating.
• Let the pot cool before washing. Plunging a hot pot into cold water can warp it.
• Don't use the pot on a hob. It's oven-safe up to 240°C, but it's designed to sit in the cooker base, not on a gas ring or induction plate.
• Wipe the inside of the base with a damp cloth if anything spills over.

Ninja compared with the other kitchen brands we sell

Against Cuisinart: both make temperature control kettles. The Cuisinart glass kettle lets you see the water, while the Ninja shows the exact live temperature on a display and offers more fine control. Cuisinart's Spice and Nut Grinder does a different job from the Ninja chopper: it's for dry spices and nuts, not wet ingredients.

Against Instant Pot: the Instant Pot Classic Mini pressure cooks, which makes stews and pulses much faster. The Ninja PossibleCooker is bigger, sears better and is the better slow cooker. Pick based on whether speed or slow cooking matters more to you.

Against COSORI and Tower: if it's an air fryer you're after, we stock the COSORI Pro LE 4.7L and the Tower 4L digital air fryer.

Against Russell Hobbs: if you only want boiling water, a Russell Hobbs kettle is simpler and cheaper. The Ninja kettle is for people who care about temperature.

Ninja in a small kitchen

If your worktop is already crowded, here's how the five products fit in.

• The kettle lives on the side, as any kettle does. It takes up the same space as a normal 1.7 litre kettle.
• The chopper stacks: the two bowls nest together with the power pod, so it fits in a cupboard.
• The Nutri Ninja is slim and stores in a cupboard with its cups.
• The Ninja Blast is about the size of a large water bottle and can live in a bag or a drawer.
• The PossibleCooker is the big one. With a 6 litre pot, it needs a deep cupboard or a corner of the worktop. Because it replaces a slow cooker, a rice cooker and a steamer, it can free up space if you already own those.

Ninja as a gift

Ninja products make good presents because they tend to feel like a treat while also being genuinely useful.

• For a tea or coffee lover: the KT200UK kettle. Add a bag of good loose-leaf tea or freshly roasted coffee.
• For a student or someone starting their first job: the Ninja Blast. It goes from halls to the gym to the office.
• For a keen home cook: the Stackable Chopper. It's small, affordable and used constantly.
• For a busy family or a couple who've just moved in together: the PossibleCooker.

Why we chose Ninja

We picked Ninja products that solve everyday jobs rather than ones that look impressive and then gather dust. A kettle you'll use every day. A chopper that makes cooking from scratch quicker. Two blenders for two different lifestyles. And a multi-cooker that fixes the most common complaint about slow cookers. They're well designed, they're powerful, and the bits that touch food are easy to wash.

Frequently asked questions

Is Ninja the same company as Shark?

Yes. Both brands are owned by SharkNinja. Ninja makes kitchen appliances and Shark makes cleaning and hair care products.

Is Ninja a British brand?

No, though it's very popular here. SharkNinja started in Canada, is headquartered in the United States and runs its European business from a company registered in Leeds.

Can I use the Ninja kettle for baby formula?

NHS advice is to make up formula with water that has been boiled and left to cool for no more than 30 minutes, so it's still at least 70°C. That temperature helps kill any bacteria in the powder. Follow the NHS guidance and the instructions on your formula, rather than relying on a preset alone. Using fresh water that has been boiled to 100°C first is the safest approach.

Can the Ninja Blast crush ice?

It handles ice and frozen fruit, as long as you add enough liquid. For best results, put liquid in first and don't overfill.

Can I put hot liquids in the Nutri Ninja or Ninja Blast?

Don't blend hot liquids in a sealed personal blender cup. Heat and pressure can build up and force the lid off. Let soups cool first, then reheat after blending.

Does the PossibleCooker pressure cook?

No. It sears, slow cooks, steams, cooks rice and pasta, makes porridge and keeps food warm. For pressure cooking, see the Instant Pot Classic Mini.

Can the PossibleCooker pot go in the oven?

Yes, up to 240°C. Use oven gloves, as the pot and handles get very hot.

Is the Ninja chopper good for nuts?

Yes, it chops and grinds nuts. Pulse in short bursts so they don't turn into nut butter, unless that's what you're after.

Are Ninja parts dishwasher safe?

The removable bowls, cups, lids and the PossibleCooker pot are dishwasher safe. The motor bases and power pods are not. Check the manual for each product.

How long does the Ninja Blast battery last?

Ninja says you get 10 or more blends per charge, and a full charge takes about two hours. Thicker blends with lots of ice use more battery.

Can I make baby food with the chopper?

Yes. Cook vegetables or fruit until soft, let them cool, then pulse to the texture you want. Add a little of the cooking water for a smoother purée. The stackable bowls with lids are useful for storing portions in the fridge.

Can I cook rice and steam vegetables at the same time in the PossibleCooker?

It runs one function at a time. The simplest approach is to cook the rice first, tip it into a covered dish to stay warm, then use the steam function and rack for the vegetables. Check the recipe guide in the box for Ninja's own suggestions on combining the two.

Is the Ninja kettle worth it over a normal kettle?

If you only drink builder's tea and instant coffee, probably not; a standard kettle does the job. If you drink green tea, brew coffee with a cafetière or pour-over, or like to top up a cup through the morning without reboiling, the temperature control and Hold Temp make a noticeable difference you'll get every day.

Does the Ninja kettle show the temperature while it heats?

Yes. The digital display shows the live water temperature, so you can watch it climb and see exactly when it reaches your setting.

Why isn't my smoothie blending smoothly?

Usually there isn't enough liquid or the cup is too full. Add a splash more liquid, take out a bit of frozen fruit and try again. Putting liquid in first helps the blades get going.
