Questions about Thermoscup.

What is a thermos flask?
A thermos (or vacuum flask) is a double-walled container with a vacuum gap between the walls. That vacuum barely conducts heat, so it slows down how fast a hot drink cools or a cold drink warms up - that's what keeps drinks at temperature for hours instead of minutes.
How does Thermoscup keep drinks hot or cold?
Thermoscup uses double-wall 304 stainless steel vacuum insulation, the same principle behind any quality thermos flask. It's rated to keep drinks hot for up to 12 hours and cold for up to 24 hours, so your morning coffee is still warm at lunch.
How do I clean my Thermoscup?
The wide mouth opening is designed for easy cleaning - hand wash with warm soapy water and a bottle brush, rinse thoroughly and air dry with the lid off. The tea separator lifts out to clean separately. Avoid dishwashers and abrasive cleaners, which can damage the seal and the LED display.
Is Thermoscup BPA free?
Yes. All parts that touch your drink are BPA-free, food-grade 304 stainless steel.
What is the LED display, and does it need charging?
A small digital display is built into the cap and shows your drink's live temperature in °C as soon as it senses liquid - no buttons, no app, no charging cable to lose.
What's included in the box?
One Thermoscup Smart LED Flask in your chosen colour, with its removable 304 stainless steel tea separator fitted.
How is Thermoscup different from a Stanley flask?
Both are vacuum-insulated stainless steel flasks. Thermoscup adds a live LED temperature display built into the cap and a removable tea separator as standard, in a slimmer everyday-carry size.
What is your returns policy?
30 days to return an unused Thermoscup in its original condition for a full refund. See our Returns Policy for the full details.
Where do you deliver?
We currently deliver within the UK only. See our Shipping Policy for delivery timescales and costs.
