1. The power of the hair dryer is closely related to the air volume. Generally, the higher the power, the larger the air volume, and the faster the drying speed, but the price is higher than that of the hair dryer with low power. In addition, a hair dryer with high power has a large radiation, because its heating wire is thick, and the more heat energy is generated, the radiation will become larger. Therefore, when purchasing, it is not the better to choose a hair dryer with higher power, as long as it can meet your own needs, the power is not too low. Usually, the power of 22v for home use can already meet the demand.
2. Common hair dryer powers are 250 watts, 350 watts, 450 watts, 550 watts, 850 watts, 1000 watts, and 1200 watts. When purchasing, first understand the different power levels and the use effect of the hair dryer, so as not to buy the wrong one, resulting in the use effect that does not meet your expectations.
