WHY THIS ONE
Cold coffee is a solved problem
Every desk worker knows the third-sip disappointment: the meeting ran long and the mug went cold. A warming plate holds your drink at temperature so the mug waits for you, not the other way round.
- Warm for hours
- The heating plate maintains drinking temperature through calls, sprints and lost track of time.
- Desk-sized footprint
- At 130 × 110 × 23 mm it takes coaster space, not desk space.
- Built like an appliance
- ABS body over a metal heating surface, made for daily duty.
- Simple to run
- Set the mug down, switch on, forget about it.
HOW TO USE IT
Warm drinks on autopilot
-
1
Place the warmer
Flat spot beside the keyboard, cable to power.
-
2
Set your mug on it
Flat-bottomed mugs make the best contact.
-
3
Switch on and sip
The plate holds temperature; lift, drink, return.
Important: this is a warmer, not a kettle — it keeps hot drinks hot rather than heating cold ones from scratch.

BEFORE YOU ORDER
Questions people ask
Will it boil water?
No — it is a keep-warm coaster. Start with a hot drink and it holds the temperature there.
USB or plug version?
M306 (USB) is the desk-friendly pick for laptops and adapters; M316 versions use a 220V wall socket — check your region’s plug before choosing.
Does the mug material matter?
Flat-bottomed ceramic and metal mugs transfer heat best; avoid double-wall insulated cups, which block the warmth by design.
How does the multi-buy discount work?
It comes off on its own at checkout, with no code to type. Two items anywhere in your basket take 10% off, three take 15%, four take 20%. They do not have to be the same product.
When will it arrive?
Orders are dispatched within 1–2 business days and tracking is emailed as soon as the parcel leaves. If it is not for you, unused items can be returned within 30 days — email us first for the return address.
