I'm currently looking for a coffee-warmer pad with USB port so that I can plug it into the laptop.
The selection is huge and most products have no customer reviews.
Does any of you have experience with such pads and can recommend me which?
This is a typical China product. "Good" USB coffee warmer will hardly exist. In addition, coffee tastes only fresh anyway, prefer to make smaller cups and more often get fresh.
I can't recommend it. These devices where you just put the coffee on it do not bring much, if only because heat transfer is bad and with USB they bring even less. Usb only makes 2.5-5 watts. It's nothing.
USB PD also provides up to about 80 watts, as you would be slowly in the right direction. But cheap China products certainly do not have a USB PD, and your devices probably will not.
The performance on a USB port is never enough for this and never, the coffee remains at most lukewarm.
