Need something to control the power going into USB heating element

[OM2]

Frodo1 linked to it.

Thanks for all replies. The link he gave were for motorbikes. But that also had the thing I needed!
I found just the item itself: https://www.aliexpress.com/item/1005004402508842.html (USB 5V-12V Temperature Controller Heater Thermostat 3-Speed Adjustable 24W). Under £2. That will do nicely.
Just what I needed.
Thanks!

Under £2. That will do nicely.

Plus postage (USD$2.00 equivalent), Plus VAT.

But if I have to get up and move every 5 min - they're a pain, as I have to plug and unplug. My next project after solving the temp control would be a magnetic connecter so I can connect and disconnect easily

Or a powerbank so that power source goes with you too?

My apologies for not noticing your "want" for a "magnetic connector" earlier!

Magnetic "Pogo Pin" connectors are readily available - both with and without "leads"

I use a two pole, concentric version, on my phone, to charge it. A tiny adaptor plugs into the socket, then a usb lead matches it. When they get near, they snap together. One lead in car, one at the side of my bed, I built into a DIY stand, one in the living room.
