heats up as expected , works well on my power bank . be good under my pillow in the winter

Courier took so long and had a lot of pressed. But the product is very unsatisfactory.

Heats well, consumption 5 V./1.7 A. For how much I do not know.

From the paverbank they warm though they look flimsy

It came, it looks like all the rules, it is heated.
