Lost my thermostat button for my dew heater, any alternatives/backups?

[WilliamAstro]

I just lost my thermostat button that controls the heat to the dew heater for my lenses.

It has three options "Low, Middle, High".

Is there a spare of the same thing or similar? Cheers

P.S. This is where I got it from

Amazon have a similar controller though it ends in a DC plug for £8.49

Aliexpress seem to have the same controller for £4.53 and free shipping from China.

do you think it doesnt need this and it can just heat up via a power bank? because these seem to have long delivery

If you don't have the controller in circuit and directly connect the the dew heater to the power bank, it will run the same as if the controller is set to high power. If this isn't too warm then you can use it this way with no problems. 🙂
