2. Voltage converter - Wikipedia

   en.wikipedia.org/wiki/Voltage_converter

   A simple voltage dropper can be used to reduce the voltage for low-power devices; if more than 12V is required, or for high-powered devices, a switched-mode power supply is used. The output will usually be DC in the range 1.5–24 V. Power supplies that output either 100–120 V AC or 210–240 V AC are available; they are called inverters ...

3. Catalytic heater - Wikipedia

   en.wikipedia.org/wiki/Catalytic_heater

   Catalytic space heaters generate infrared heat to raise the temperature in a given area. [2] In addition to the larger catalytic heaters there are also small hand warmer or pocket heaters that use a catalyst combustion unit. Current units use a glass fiber substrate coated with platinum. Cheaper units may use other catalysts that do not work as ...

4. Buck converter - Wikipedia

   en.wikipedia.org/wiki/Buck_converter

   A buck converter or step-down converter is a DC-to-DC converter which decreases voltage, while increasing current, from its input to its output . It is a class of switched-mode power supply . Switching converters (such as buck converters) provide much greater power efficiency as DC-to-DC converters than linear regulators , which are simpler ...

5. Self-regulating heater - Wikipedia

   en.wikipedia.org/wiki/Self-regulating_heater

   A positive-temperature-coefficient heating element (PTC heating element), or self-regulating heater, is an electrical resistance heater whose resistance increases significantly with temperature. The name self-regulating heater comes from the tendency of such heating elements to maintain a constant temperature when supplied by a given voltage.
