  • Geeky USB cup warmer

    Value for money. Plugs in to USB slot, has an on/off switch so no need to pull it out of USB slot when you don't need it on.

    Actually gets hot enough that you can't keep your hands on it otherwise you'd burn yourself.


    Doesn't keep my coffee warm enough, as another reviewer has said, it best suits cups with a FLAT bottom. This is very true, my cup has a curved bottom so the contact patch is not much.


    Great value for money. You might need to buy a new cup to make the most of this warmer though.
