Surge protector manufacturer answers whether the ampere rating of laptops and desktops is the same, and whether the ampere rating is 12A, 13A, 15A, 20A or 30A.
Surge protector manufacturers ask if the amperes of laptops and desktops are the same.
The amperes (i.e. the size of the current) of laptops and desktops are usually different. Voltage protector manufacturers tell you that this is because there are significant differences in the power supply design, hardware configuration, and power consumption requirements. Here is a specific analysis:
Power supply design difference:
For portability, laptops usually use low-voltage power supply designs to reduce energy consumption and extend battery life. The current and voltage provided by their power adapters are carefully designed to meet the laptop’s power consumption requirements in a limited space.
Desktops focus more on performance and use standard voltage power supplies, and because they have independent hosts and larger spaces, their power supply design can be more flexible to support higher power consumption and stronger hardware configurations.
Different hardware configuration:
The hardware configuration of laptops (such as CPU, graphics card, memory, etc.) is usually more compact and integrated than that of desktops, so their power consumption and current requirements are relatively low.
The hardware configuration of desktops is more flexible and powerful and can be upgraded and expanded according to user needs, which also leads to an increase in their power consumption and current requirements.
Power consumption requirement differences:
Laptops typically have lower power consumption requirements and therefore smaller amperages due to portability and battery life limitations.
Desktops do not have these limitations and can support higher power consumption and current requirements to provide stronger performance and a better user experience.
Differences in the amperage of laptops and desktops
There are differences in the amperage of laptops and desktops. Laptops generally have lower currents, while desktops have higher currents.
For example, laptops generally have a current of about 100-300 mA (0.1-0.3 A) during normal operation. Some settings also consider that the current is about 1A, 2A, or 3A, which may be related to different models and loads.
Desktops generally have a current of 1.5A to 1.7A, but may also vary depending on the configuration and external devices. In some cases, desktops may have a higher current, such as some high-configuration or high-performance desktops, which may exceed this range.
Surge protector manufacturers tell you that due to differences in hardware configuration, power consumption requirements, and power supply design between laptops and desktops, their current amperages will also be different. Therefore, when selecting a power supply or performing power-related operations, it is necessary to determine the appropriate current amperage based on the specifications and requirements of the specific device.
The current amperage of laptops and desktop computers is not fixed at 12A, 13A, 15A, 20A, or 30A, but varies according to the specific model and configuration.
In general, the current amperage of laptops is smaller, most of which are around 3A.
This is because laptops usually use low-voltage power supply design for portability to reduce energy consumption and extend battery life.
The current amperage of desktop computers is relatively large, and there may be multiple different output currents, such as 15A, 30A, etc., depending on the specifications and configuration of the power supply. The power supply design of desktop computers is more flexible to support higher power consumption and stronger hardware configuration.
Due to the significant differences in power supply design, hardware configuration, and power consumption requirements between laptops and desktop computers, their current amperage is usually different.
Surge protector manufacturers tell you, when selecting a power supply or performing power-related operations, it is necessary to determine the appropriate current amperage based on the specifications and requirements of the specific device, rather than simply selecting a fixed value.
