I want to get a mug warmer for my desk to avoid having to throw away/microwave (bleugh) three-half finished mugs of tea a day.
I had one previously which my husband has snagged which was powered by a standard plug. I'm wondering through, now that I have a USB hub with plenty of free slots, whether I should pick a replacement with a USB power lead which I run off my laptop.
Is one safer than the other? Am always a bit cautious when ordering electronics from Amazon.
