Need something to control the power going into USB heating element

I've got some USB heated gloves
They're wired and you need to connect to a USB connection

They're brilliant!
Except they get too hot for my liking
There's no controls for turning heat up or down
Is there a device I can add tot he middle that varies the power or voltage going to the gloves?
I'm sure I've seen something like this before - i just can't remember where!

I was hoping on of you guys might know

Thanks
