Keep that mug of coffee drinkable through a long stretch of work.
This USB mug warmer holds coffee, tea, or hot chocolate at a comfortable drinking temperature. It plugs into any powered USB port and gives most standard mugs a stable warming surface. An on/off switch with an indicator light shows at a glance when it is running.
Why we picked it
- Simple USB power - Runs from laptops, desktop PCs, or USB adapters wherever you work.
- Clear indicator - The switch light tells you when the warmer is on.
- Slim and portable - Light enough for a laptop bag; good for offices, dorms, and cafes.
Good to know
Plug it in, switch it on, and set your mug on the flat plate. It keeps already-hot drinks warm; it will not heat a drink from cold. Flat-bottom ceramic or metal mugs make the best contact. For safety, switch it off and unplug when you step away.
Common questions
Q: Will it heat a cold drink?
A: No. It keeps an already-hot drink warm; it does not boil or heat from room temperature.
Q: What mugs work best?
A: Flat-bottom ceramic or metal mugs. Thick or double-walled insulated mugs hold heat differently.
Q: Can I leave it on for hours?
A: It is made for extended desk use, but turn it off and unplug it when you leave your workspace.
Q: What powers it?
A: A standard USB connection: computers, powered USB hubs, or USB wall adapters that meet standard output.
