Power
The rated power of a massager is more of a reference than a practical concern for most users. Generally, massagers consume less than 80 watts, with higher ratings, up to 400 watts, observed in specific chair cover models that heavily rely on extensive infrared heating. However, power consumption is usually not a significant factor, especially for models powered by a household outlet. Manufacturers carefully select power levels to ensure the effective performance of claimed functions and modes. When choosing a massager, it's more practical to focus on other relevant aspects rather than getting overly concerned about power ratings.
Number of programs
The number of individual operate programs provided for in the design of the massager.
It's important to distinguish this from massage modes (as discussed below). A single program can integrate multiple massage modes, such as vibration and infrared heating. Consequently, the count of programs may not necessarily align with the number of distinct massage types.
Anyway, the more modes, the more versatile the massager, the more ways it can be used. However such an abundance can affect the price.
