Pressure cookers and electric pressure cookers are both cooking tools that utilize high pressure during the cooking process to shorten the cooking time and maintain the nutrients and taste of the ingredients. Here are their respective features:

1. Pressure cooker: Pressure cooker is a traditional pressure cooker that generates steam by heating, which raises the internal pressure, thus increasing the boiling point of water and speeding up cooking. Pressure cookers usually need to be heated using gas or induction cooktops.

Advantages:

Easy to use and relatively simple to operate.

Relatively low price.

Suitable for all types of stewing and cooking processes.

Disadvantages:

Requires manual adjustment of heat and time.

Temperature control is not as precise as an electric pressure cooker.

Needs to manually keep the pressure stable.

2. Electric Pressure Cooker: Electric Pressure Cooker is an upgraded version of pressure cooker, which integrates an electric heating element and an intelligent control system to automatically adjust the temperature and pressure, providing greater functionality and convenience.

Advantages:

The cooking process is fully automated, with intelligent control of temperature and pressure.

More precise temperature and pressure control.

More diverse functions, such as preset recipes and keep warm.

Disadvantages:

Relatively high price.

Requires access to a power source for use.

Some electric pressure cookers may have reliability or durability issues.

In summary, pressure cookers and electric pressure cookers each have their own characteristics and applicable scenarios. If you focus on convenience and intelligent cooking experience and are willing to invest more money, electric pressure cooker is a good choice. And if you are more focused on price and simple operation, while happy to manually adjust the heat and time, then a traditional pressure cooker can also meet your needs. The final choice depends on personal preference and practical needs.
