Heated glove? Answered

Ok 50 inch of nichrome is not helpful without the diameter.

The thicker it is the more current it will take and not get hot at all.

So we can't guess from your lack of specks.

That being said apply power with an adjustable power supply to the heater.

A good adjustable power supply should display volts and amps, with a cheep adjustable power supply you can use a meter to find the volts and amps.

Start at the lowest power and raise the volts and amps until the glove is 110 degrees. A thermometer is needed here.

That is your max power.

Then use a thermostat to regulate the heat in your glove.

Now you might want to just jump to a thermostat and you can do that but it won't tell you the power needs of the gloves.

If the gloves need 12 volts at 2 amps for 4 hours to maintain 110 degrees, you need a 12 volt battery good for over 10 amp hours.

Depends on the gauge of the Nicrome wire. best fit a temperature controller i.e. a thermostat.
