Night feeds, quietly rewritten

The bottle is ready before you are

Nobody warns you that the hardest part of the night isn't the waking up. It's the four minutes afterwards: the kitchen light that's far too bright, the water that's never quite right, the bottle shaken and tested and shaken again, all one-handed because the other arm is holding a very cross baby with opinions. You get there. You always do.

With the Warmer Pro, the milk is already waiting at 37°C, held within a degree of it, and it stays that way for up to 14 hours on a single charge. From the fridge, it's ready in about two minutes. There's no plate and no adapter, so your usual bottles simply work, and the beep switches off so nobody else in the house stirs.

One quiet gesture tonight, and 3am becomes a much shorter story.

Real Relievoo nights, beginning at the bedside at 3am.

Why thousands of parents choose Relievoo

Real routines, real feeds — here's what parents tell us most often.

★★★★★

Perfect for long journeys

✅Used it on a 4-hour drive — no more stopping to hunt for hot water. Set the temperature before the feed and the milk was ready exactly when we needed it.

★★★★★

Finally got baby to take the bottle

✅Finding a warmer that holds breast milk at exactly the right temperature was a lifesaver — our baby now takes her bottle consistently and I can leave her without worrying.

★★★★★

So easy anyone can use it

✅Set up in seconds, slips into the changing bag, and we use it every single day — it just works.

Because Babies Don't Wait

Hunger doesn't check where you are. The Relievoo warmer makes sure you're always ready.

👶

Ready when baby is hungry

Warm milk wherever you are, without hunting for hot water or a plug socket.

🚗

Stress-free days out

Perfect for pram walks, road trips and holidays when feeding plans don't go to plan.

🌙

Easier night feeds

It keeps milk warm at your set temperature for up to 14 hours — no trips downstairs, no waiting around.

❤️

More freedom for parents

Feed on your schedule, not around access to hot water.

Designed for Everyday Parenting

Every detail exists to make one more feed easier than the last.

✓ At least 12 feeds per charge

A 14-hour battery covers days out, travel and everyday use — and tops up with USB-C from any phone charger or power bank.

✓ Constant temperature control

Choose any temperature from 37 to 60 °C and it holds there at ±1 °C until you're ready to feed.

✓ Works with every bottle brand

Relievoo warms the milk itself, so there's nothing to attach and no adapters to buy. Keep the bottles your baby already knows and loves.

✓ Keeps milk warm for up to 14 hours

Set it once and a feed is ready the moment baby asks — no reheating between feeds.

Will It Work With My Bottle?

YES — EVERY BOTTLE, EVERY BRAND

The Relievoo warms the milk directly in its food-grade stainless-steel chamber, then you pour it straight into whichever bottle your baby already loves — Avent, Tommee Tippee, MAM, Dr Brown's, Medela, Lansinoh, glass or plastic.

No adapters. No brand-specific heating plates. No compatibility chart to check.

Because we heat the liquid — not the bottle — it also works for formula water and keeps working when you change bottle brands as your baby grows.

Why Settle for a Warmer That Makes You Wait?

Most cordless warmers still ask you for the right adapter and the best part of ten minutes. Here is what changes when neither is needed.

Relievoo

Others

Fits your baby's bottle

✓Any brand, any bottle. We warm the milk in the chamber, so there is nothing to fit.

✗Most need a heating plate matched to your bottle brand, or an extra adapter.

Time from fridge to feed

✓About 2 minutes from the fridge. Around 60 seconds from room temperature.

✗Typically 7 to 9 minutes, and for a smaller volume.

Temperature control

✓Anywhere from 37 to 60 °C, adjusted continuously and held to ±1 °C.

✗Usually a handful of fixed settings, roughly 37 to 50 °C.

Bottles per charge

✓At least 12, on a 14 hour battery.

✗Typically around 6.

Keeps milk at your temperature

✓Up to 14 hours at the temperature you set.

✗Most are built to warm, not to hold.

Weight in the changing bag

280 g

Typically 350 to 400 g

Charges your phone too

✓Yes. USB-C in and out, so it doubles as a power bank.

✗No

Warranty and returns

✓Lifetime warranty, plus 30 days to change your mind.

✗Typically 1 year.

Figures shown for other portable warmers are typical published specifications for cordless bottle warmers on sale in the UK in August 2026. They vary by model, and no individual brand is referred to. Relievoo figures refer to the Cordless Bottle Warmer Pro.

And compared with what is already in the kitchen: a plug-in warmer needs a socket, so it stays at home. A kettle or a microwave gives you no temperature setting and can leave hot spots.

How It Works

Three steps. About two minutes from fridge-cold to feed-ready.

1

🍼Pour

Pour milk or water into the stainless-steel chamber — up to 300 ml.

2

🌡️Set

Choose any temperature from 37 to 60 °C. A visual signal and a beep tell you the moment it's ready.

3

🍺Feed

Pour into your baby's bottle and feed — wherever your day takes you.

Easy to Clean. Designed for Everyday Use.

No plates, no small parts, no fuss.

The food-grade 304 stainless-steel chamber has no coating to scratch and no brand-specific parts to look after. After a feed, rinse it with warm soapy water and wipe it dry — it dries spotless and it's ready for the next bottle.

Out and about? A quick wipe with an unscented, alcohol-free wipe keeps it fresh between feeds.

⚠️Do not submerge the base in water — the chamber rinses clean, the base wipes clean.

FAQ

How long does it take to warm milk?+

About 2 minutes from fridge-cold to 37 °C, and around 60 seconds from room temperature. Heating time varies slightly with milk volume and ambient temperature.

Will it work with my bottle?+

Yes — with every bottle brand. The Relievoo warms the milk itself in its stainless-steel chamber, so there are no adapters or brand-specific parts. Avent, Tommee Tippee, MAM, Dr Brown's, Medela, glass or plastic: pour, warm, and pour back.

Can I use it with breast milk and formula?+

Yes — both. Set 37 °C for expressed breast milk and it holds there at ±1 °C. For powdered formula, follow the NHS guidance and prepare it with water of at least 70 °C first; the warmer is perfect for gently warming ready-made formula or keeping a prepared feed at temperature.

How do I clean the warmer?+

✅ Rinse the stainless-steel chamber with warm soapy water ✅ Wipe with unscented, alcohol-free wipes on the go ❌ Do not submerge the base in water

What if I'm not happy with my purchase?+

Every warmer comes with a 30-day money-back guarantee — return it for a full refund, no questions asked. It's also covered by our lifetime warranty: if anything goes wrong, we replace it.

Innovative and Practical Features

Every gram and every degree has a job to do.

Unplug and Go

True freedom for parents. Cord-free and hassle-free.

Forget hunting for outlets or lugging clunky equipment. At just 280 grams — lighter than a small water bottle — the sleek cordless design warms a bottle effortlessly at the park, at friends' places or on a long journey. It slips into any changing bag and even tops up your phone with its USB-C power-bank output.

Fast and Gentle Heating

No more waiting, no more worries.

Fridge-cold milk reaches 37 °C in about 2 minutes — around 60 seconds from room temperature. The chamber warms the milk evenly, so there are no microwave-style hot pockets. Just say goodbye to guesswork: a visual signal and a beep (which you can switch off for night feeds) tell you the exact moment it's ready.

Any Temperature. Exactly.

Continuously adjustable from 37 to 60 °C, held at ±1 °C.

No fixed steps to settle for: dial in the exact temperature your baby prefers, anywhere between 37 and 60 °C, and the warmer holds it there at ±1 °C for as long as you need — up to 14 hours. Set 37 °C for expressed breast milk and it stays gentle, feed after feed. No more testing on your wrist.

Long Lasting Battery

Reliable power, day and night.

With at least 12 bottles per charge and a 14-hour battery, you're covered for a full day out or several night feeds. Recharge with any USB-C cable — from a phone charger, a laptop or a power bank — so you're always ready for the next meal.

Ready to simplify feeding time and reclaim your freedom? Join thousands of parents enjoying stress-free feeds, wherever life takes them.
