There must be more interesting ways than this of keeping your girfriends hands toasty. We have had electical and chemical suggestions. How about a biological approach?

Have you consiered using a transistor connected as a variable resistor?

Fix the transistor/s so the metal is the heatsink. Use a temperature sensor in the transistors bias circuit

(This is a good way to use up those power transistors that you buy at £1 for 20 and turn out to be out of spec - low gain / high leakage)

As has already been said previously, it's asking a lot of a small battery. It would need a large and heavy battery to produce any useful or worthwhile heat. It may be better to look at other energy sources.

Could it be possible to modify a portable gas soldering iron or butane powered tongs/hair curlers? The catalytic element produces heat without a flame and the item can be refilled with lighter fuel gas.

Battery heated gloves are sold for people who ride snowmobiles and motorcycles.

Any for motorcycles.

But don't they plug into the vehicle battery?

Hee, hee.
Keep her freezing hands away from there!
I think ordinary insulated gloves would just keep her cold fish hands cold.

Buy her a hat. Her head loses a lot of heat and her body compensates by reducing blood flow to her extremities. With a hat on her head then her hands and feet will be warmer.

bitem2k Can’t you still understand what she expects from you? It’s one of girl’s tricks.
She is asking for you. Stay with her as much as closer…….

Getting cold or hot is normal. Human body is always adjusting to the nature.

If you run fast you will be sweat. Why is that????? Your machine will get hot. So the sweat is cooling your body.
If you stay in a very cold area how you staying????? By keeping your hands across the body by keeping tight. Why is that????

A doctor will explain this very well. I just showed you some examples.

No need to apply balms or no need to find electronic items to keep her hands warm.
Doctors & manufactures accept but also it has some side effects too. These effects will show you after a long time not now.

Be careful with these artificial techniques. Doctors’ recommendation is a must.

Do you like to see your girl is getting older before you?

Ok, thanks eveyone for the suggestions.

why don't you just hold her hands ?

the main problem is battery power required
