A normal mug has one job: hold a drink. A temperature control mug has a second one: keep that drink at a heat you chose. The idea is simple. The details are where people get unsure, mostly about batteries, safety, and what happens if they use it wrong. So let us go through them.
A temperature control mug combines an insulated body with a small battery-powered heating system and a temperature sensor. You set a target temperature, the sensor watches the drink,k and the mug adds just enough heat to hold it there. The Slursh Temperature Control Smart Mug holds 50°C to 62.5°C, accurate to about ±1°C, and runs about 1.5 hours on battery or all day on its wireless charging coaster.
Two layers: insulation and active heat
The body is double-wall vacuum insulated. The vacuum gap between the two walls slows the rate at which your drink loses heat to the air. Insulation alone only slows cooling. It cannot stop it.
The active part is the heating system. Slursh calls it the Intelligent HeatLock system. Sensors read the temperature of the drink, and the mug adds heat to keep it where you set it.
What happens when you use it
- Set and sip. Pick your temperature on the LED touch display. You can switch between °C and °F.
- HeatLock. The sensors hold your chosen warmth to within about ±1°C.
- Coaster power. Sit the mug on the wireless charging coaster, and it keeps running all day at your desk.

What it is not
It is not a kettle. Pour in a hot drink, and the mug holds it there. It is also not made for cold drinks. If you want ice-cold water for the gym, a different bottle will do the job better.
Is it safe?
Drink temperature. IARC, part of the World Health Organization, classified drinking very hot beverages, above 65°C, as “probably carcinogenic to humans” in 2016, linked to oesophageal cancer. The Slursh mug’s top setting is 62.5°C, which is below that line. That is a useful fact rather than a promise. No temperature is risk-free, so if you have a throat or stomach condition, ask your doctor what suits you.
Scalds. Hot liquid can burn, whatever the mug. Keep the lid on when you move around, and keep it out of reach of small children.
Electronics. There is a battery and electronics inside. Use the charging cable and coaster that come with it, and follow the care instructions in the box when it comes to water and cleaning.

Care basics
Cleaning a mug with electronics is different from cleaning an ordinary one. Our cleaning and care guide for the smart mug walks through it step by step.
Who it suits
Slow sippers at a desk. People who work from home and forget their tea. Anyone tired of microwaving the same cup three times a morning. If you drink quickly or want something to throw in a bag, a simpler insulated bottle is the better pick.
