✦ Frequently Asked Questions
Will it heat milk from cold?
Slowly, and that is the honest answer. A USB heating film is low wattage — it is built to hold milk at feeding temperature and to take the chill off, not to heat a fridge-cold bottle in two minutes. If you need fast heating from cold, you want a mains countertop warmer instead.
So when is it actually useful?
Warm a bottle at home, wrap it, and it stays drinkable through a car journey or an afternoon out. That is the job it does well.
Does it have a temperature display?
No. There is no readout and no thermostat you can set. Always test milk on your wrist before feeding, exactly as you would with any warming method.
Can I leave it running unattended?
Don't. Unplug it when you are not using it, and never leave it heating overnight or with a child unsupervised.
What powers it?
Any USB source — a power bank is the most practical for a nappy bag. Output varies between chargers, so a low-output port will warm more slowly.
How do I clean it?
Wipe the faux leather with a damp cloth. Do not submerge it or put it in a steriliser — there is electronics inside.

WHY YOU NEED THIS
Why You'll Love Having This
Milk goes cold on the way to wherever you're going, and there is rarely a kettle when you need one. This wraps around the bottle and runs off a power bank, so a bottle warmed at home is still drinkable an hour into the trip.
Runs Off Any USB
A power bank, a car charger or a laptop port — no wall socket, and no waiting to find a kitchen.
Holds Temperature on the Move
Built to keep an already-warm bottle at feeding temperature through a car journey or an afternoon out.
Fits the Bottles You Have
An adjustable closure rather than a rigid cradle, so narrow-neck and wide-neck bottles both work.
Doubles as a Hand Warmer
Genuinely useful on a winter pram walk once the feed is done, and it rolls flat into the bag.
