Ninja kettle that ‘saves money’ and has rapid boil speeds now £40 off

The Ninja Perfect Temperature kettle has a 4.6 star rating on Amazon alone, with customers praising it as ‘one of the best’

Amazon shoppers are lauding praise on a kettle by kitchen gadget experts that ‘keeps the water hot for 30 minutes’ and ‘saves energy’ – and it’s currently on sale. Reduced from £99.99 to £59, the Ninja Perfect Temperature kettle comes in a sleek matte black hue, which is such a stylish addition to kitchens.

While most kettles have a simple lever to generate heat, this Ninja kettle is a little more high-tech and comes with a base on which a digital display provides real-time temperature read-outs as it climbs. The base also features six pre-set temperatures ranging from 60°C to 100°C, which can be selected at the touch of a button.

It’s got a relatively large 1.7L capacity, too, which is essentially enough for seven cups of tea or coffee, and boils in under 50 seconds, which is pretty rapid compared to the average of two to four minutes.

For those who tend to forget about their tea, the kettle also has a clever function that holds the temperature of the water for up to 30 minutes, which is great for those who need a hot water top-up or want to make a second drink with no need to re-boil.

Ninja isn’t the only place where shoppers can get a smart kettle, as Lakeland’s own Digital Double-Walled Kettle is £44.99 and has a temperature adjustment system as well as a keep warm function. Meanwhile, Bosch’s Styline Variable Temperature Kettle is on sale for £60 from £85 and has a two-tone silver and black design as well as an adjustable temperature control with four different settings.

Although with £40 off, the limited-time deal on this Ninja kettle is pretty decent, especially as it’s had some rave reviews from users who praise it as ‘one of the best’ and a 4.6-star rating.

One person left a five-star review, which read: “Ninja products have always been a staple in both my home and my family’s homes — we’ve always rated them highly — and this kettle is no exception. One of my family members bought it first, and after seeing it in action, I knew I needed one too.

“I’ve had it for about a month now and genuinely don’t regret the purchase. It boils quickly — within seconds to a couple of minutes, depending on how much water you’re heating — so you’re not waiting around long.

“One of my favourite features is the temperature selector. I drink matcha regularly, and 80°C is the ideal temperature for it. Being able to set the kettle to 80°C instead of boiling to 100°C makes a noticeable difference in flavour — it tastes smoother and less bitter compared to when I was using a standard kettle.“Another feature I love is that it holds the temperature for up to 30 minutes. This is perfect if you’re like me and get distracted halfway through making a drink.”

Someone else noted: “The Ninja Perfect Temperature Kettle has genuinely impressed me from the first use. It heats water incredibly fast, and the temperature control is spot‑on. Whether I’m making coffee, tea, or anything that needs a specific heat level, it delivers exactly what I want every time.

“No more guessing or waiting around. The build quality feels premium. The stainless steel design looks great on the counter, the handle is comfortable, and the lid opens smoothly. The display is clear and easy to read, and the controls are intuitive — even if you’re half-asleep in the morning.”

They also remarked on how quiet the gadget is, stating: “One of my favourite features is how quietly it boils. It’s powerful, but it doesn’t sound like a jet engine taking off. The keep‑warm function is a brilliant bonus too, especially when I’m multitasking.”

While the majority of reviews were positive, marvelling at the features of the kettle, some people were left disappointed in its longevity, with some discovering the kettle leaking after a few years. One user said: “Good, while it lasted. The temperature sensor gave up after only 13 months.”

That being said, most people have been left impressed, citing that it not only boils in a ‘matter of seconds’, but also helps ‘save money’ – one person stated: “Great for saving power. You can heat the kettle to a set temperature without boiling, taking mins off the boil time each use, so saving on power drain to your house. If like me the kettle is on throughout the day, all the mins saved each boil saves money. Great kettle, love it.”
