Comparison Bosch PHD 7961 vs Braun HD 780

The rated power of the device, in fact, is the power consumed by it when operating at maximum intensity.

The power of a hair dryer, particularly for hair dryers, is a crucial factor that determines the maximum intensity of the airflow and heating capabilities. When selecting a hair dryer based on this parameter, it's essential to consider the intended usage of the device. Models with a power below 1000 W may not be sufficient for proper hair drying, especially for long hair, and are more suitable for styling purposes. Some of these models, particularly inexpensive ones, can provide high heat with low airflow, requiring careful use. For versatile and effective use, both at home and in professional settings, it's recommended to choose a hair dryer with at least 1800 W, preferably 2000 W and higher. Higher power allows for intense airflow, effective hair drying even at lower temperatures, and provides a wide range of temperature and speed settings. Models with intermediate power levels, ranging from 1000 to 1800 W, are more suitable for travel and on-the-go use.

For curling irons, electric curlers, and similar devices, the heating intensity and speed depend directly on the power. The manufacturer carefully selects the heater's power to achieve specific performance characteristics, such as temperature and heating intensity. When choosing such devices, it's essential to focus on practical indicators and compare different mode...ls based on power, especially if specific characteristics are not clearly stated, as seen in some inexpensive curling irons with basic functionality. In these cases, users should consider the weaker and more delicate their hair, the lower the temperature and less intense the heating should be. If unsure, it's safer to opt for a less powerful device, as it may take more time to curl hair, but it significantly reduces the risk of damaging the hair.

— Joint. In models with joint adjustment of power and “degree” of air flow, the parameters change at the touch of a button. Hair dryers usually have several fixed values of blowing intensity and air temperature.

— Separate. Separate heat and temperature controls give you more freedom of choice when using your hair dryer and styler. The parameters of the flow force and temperature for hair dryers with separate adjustments change separately, which allows you to count on the optimal values of power and “degree” of blowing to avoid overdrying your hair.

The number of heating modes provided in the tool.

The presence of several temperature modes makes it possible to choose the best option for a particular situation. For example, for quick curling of "naughty" hair, when speed is more important than delicacy, you can set a strong heat, and if there are no problems over time, you can use a lower temperature. But the specific amount directly depends on the type of device (see "Device").

So, in hair dryers of one kind or another, there are usually few temperature modes — up to 3 in household models, and up to 8 – 9 (occasionally more) in professional ones. But curling irons and stylers, even relatively simple ones, can have several dozen levels of adjustment — their operating range is quite wide (for example, 130 – 200 °C), and the temperature in this range is often adjusted in steps of several degrees.

Also note that in hair dryers , temperature control and power control are carried out separately, and these parameters can have a different number of settings (for example, 2 power levels and 6 temperature levels). In curling irons, stylers, etc. the temperature only changes at the same time as the power, so the number of power modes may not be indicated at all — it corresponds to the number of temperature settings by definition.

— Turbo mode. A mode designed to dry wet hair as quickly as possible. At the same time, the speed of air movement through the hair dryer increases significantly, and the temperature remains the same. This allows you to quickly dry your hair without exposing it to high temperatures. Working in turbo mode usually involves an increased load on the device, so before using such a hair dryer, you should separately clarify in the instructions for what maximum time you can turn on turbo mode.

— Auto-rotation of the nozzle. The function of automatic rotation of a brush or other round nozzle (see "Nozzles"). Thus, the user gets rid of the need to turn the entire device when styling hair, which may not be very convenient. Note that with long hair this function should be used very carefully, as there is a risk of entangling them instead of styling.

— Cold air. The ability of the hair dryer to work without the use of a heating element — when the air flow has the same temperature as the surrounding air. This mode will be useful for drying weakened hair, especially sensitive to overheating. In addition, it can be useful during styling — in particular, cold air “fixes” the finished hairstyle.

— Ionization. An ionizer is a device for saturating the air with negatively charged oxygen ions. Optimizes styling, giving hair new posi...tive properties — for example, increased smoothness. Also, the hair is not electrified thanks to the ionizer.

— Steam humidifier. Some hair styling devices may be equipped with a container for liquid and a device that delivers hot steam to the hair. In this case, both ordinary water and a special styling liquid can be used. It is believed that the use of steam greatly facilitates the styling process, as the hair becomes more manageable. On the other hand, the high temperature of the steam can adversely affect the health of the hair, especially if the hair is weak or steam styling is used frequently.

— Alert timer. Devices with a built-in timer that makes audio signal after a set time. This function is relevant in stylers and curling irons, which allows the same time to curl curls. As a result, the hairstyle will have the same curls — there will be no imbalance in the curls when one turned out more and the other less.

— Automatic switch-off. A mechanism that ensures that the device turns off either after a specified period of time, or when a predetermined (or manufacturer-defined) temperature is reached. Prevents excessive heating of nozzles/plates, as well as overheating of the device in general.

— Key lock. The presence of a protective function of blocking the buttons allows you to avoid accidental pressing in the process of working with the device.

The ability to remove the protective grille of the hair dryer without special tools and skills, by the user himself.

The grill serves as a protective cover for the air intake of the hair dryer, located on its back side. It plays a crucial role in safeguarding the fan and heating element from foreign objects and preventing direct contact with the blades or heated coil, ensuring user safety. Additionally, the grill can accommodate an extra air purification filter, benefiting both the user and the device's internal components. The removable design of the grill greatly simplifies maintenance and repair tasks. Users can easily clean the grill and internal elements from dust and contaminants, replace or clean the filter, and fix minor issues. However, for more complex repair work, it is advisable to seek assistance from specialists.

The length of the cord for connecting to the network, provided in the design of the tool.

The long cord provides greater freedom of movement, which is particularly beneficial in hairdressing salons and beauty establishments where professionals need to move around their clients. However, for regular household use, excessive cord length can lead to inconvenience, as it may get underfoot or cause other issues. A cord length of 1 – 1.5 meters is generally sufficient for home use. On the other hand, for professional tasks, tools with a cord length of 1.8 meters or more are commonly available.
