The Moment That Matters
The 3am Feed.
She stirs. You reach for her bottle — and it's already warming.
Charged on the bedside table through the night, so the fridge-cold milk you poured in is feed-ready in about two minutes. No stumbling to the kitchen. No waiting by the kettle.
One hand cradles her, one lifts the bottle. She settles. And back to sleep you both go.
Comfort within reach — before she’s fully awake.

“Warmed her bottle on a park bench in about two minutes — no fuss, no queue for hot water. It just works.”

No adapters, ever
Works with every bottle you already own.
Relievoo warms the milk — not the bottle — so there's nothing to swap, clip on or lock in.
No adapters, no rings, no brand lock-in. Just body-warm milk, ready in about two minutes.
Loved by mums who use
Whatever's already in your changing bag, Relievoo fits it.
You Choose The Warmth
Gentle warmth, just the way she likes it.
Turn the dial anywhere from 37°C to 60°C and Relievoo holds it there — accurate to ±1°C, so every feed is warm, not scalding.
Even, all through
No microwave hot spots, no molten‑lava guesswork.
Gently warmed, not boiled
Capped at 60°C, so there’s no scalding steam.
A gentle warmer, not a steriliser — on purpose. It caps at 60°C to keep every feed soft and warm, so it stays kind to little hands and little tummies.

Customer Reviews
Good to Know
Frequently Asked Questions.
The little things mums ask before their first warm-up.
Will it fit my bottle?
Yes — any brand. It warms the milk you pour in, so there are no adapters and no brand lock-in.
Is it safe for breast milk?
It gently warms to around body temperature (~37°C), held to ±1°C with even heating and no hot spots — warm, not scalding or boiled.
Does it sterilise?
No — and that's on purpose. It's a gentle warmer, not a steriliser. It stays in the 37–60°C range and never reaches the ~100°C boil a steriliser needs.
How fast is it?
About 2 minutes from fridge-cold, or roughly 60 seconds from room temperature — around 5–10× faster than typical portable warmers.
How's the battery?
Up to 14 hours, or around 12 warm-ups, per charge. It recharges over USB-C from any phone charger or power bank — and doubles as a power bank itself.
Will it leak in my nappy bag?
No — the chamber is sealed and leak-resistant, so it travels safely tucked in your nappy bag.
Can I take it on a plane?
Yes — it's fully cordless and cabin-friendly, so it goes straight into your carry-on.
How do I clean it?
The 304 food-grade stainless chamber gives a quick, easy rinse — no fiddly parts to scrub.
