Is there anyone in your research team with a high school level knowledge of physics? The USB port has the following parameters: 5 Volts 2.1 amperes, power 10.5 Watts. If you divide this voltage by the entire heated area, the heating effect will be zero. Carbon fiber has one significant drawback in the place where water enters, the electrical resistance changes greatly, and in this place the fiber burns out. If water gets inside the jacket while driving, and or under, the heating will burn out. A heated jacket becomes a regular jacket. A power bank designed for 12 Volts giving 54 Watts at the output is really good heating, but the message says it is necessary, it needs to be constantly removed and plugged in. The fact is that USB-C outputs only 12 volts at the output, and there are no power adjustment buttons on the Power Bank. The jackets use compact Power banks with a capacity of 6000 milliampere hours, which is about the same as the capacity of a conventional smartphone battery. In the preheating mode, such a powerbank will work for 15 minutes. Carbon fiber is not the most modern material. My company produces a flexible copper-based heater that works in saltwater. If you sweat, but the heater won't burn out. My company makes heated vests as a power bank, we use a power bank for a laptop with a 24 volt output, with a capacity of 180,000 (8X18650) this is enough for 4 hours in the cold of -30 degrees Celsius. In this power bank, the heating power can be adjusted from 5 volts to 24 volts. My heated vests are powered by a power bank, a car cigarette lighter, and a 220 Volt power supply.
