Comparison Crown CMLS-121B vs Crown CMLC-530T

— Stand. Classic laptop stands include models that are not equipped with explicit additional supports — in other words, they are just platforms, without legs or other similar devices. In fact, this means that the height of the laptop on the stand depends mainly on the thickness of the platform itself. Such models are lighter, more compact and cheaper than tables, but not as versatile (although tilt adjustment is often found among this type).

— Table. A distinctive feature of the tables is the presence of rather high supports. In fact, this means that the height of the laptop depends not so much on the thickness of the platform, but on the height of these supports. In most models, they are made folding, which allows you to use the table also as a classic stand (see above); while the tables have more extensive functionality, it is in them that drawers, a place for a mouse, etc. are usually found. (See "Advanced"). Another convenience is associated with the use of laptops in the absence of tables — sitting in an armchair, lying in bed, etc.: if you have to hold the stand directly on your knees, then the table can be leaned on surrounding objects (for example, the surface of the bed). On the other hand, devices of this type are not as portable as coasters, and they are more expensive.

— Foldable Stand. Stands with folding o...r sliding elements in a design that can be adapted to a specific laptop. As a rule, holders for the device in such devices support adjustment for removal. Folding stands are compatible with many models of laptop computers, and their characteristics often indicate the range of the minimum and maximum allowable diagonal of the laptop screen. Another advantage of the foldable design is the compact size of the corresponding stands when folded, so they are easy to transport and take up minimal space in a bag or backpack.

In modern models, 1 or 2 fans are installed at a minimum, and in more advanced models this number can reach 4. It makes no sense to bet anymore, because. the area of the cooling system in this case may be larger than the area of the bottom surface of even the largest laptop. The more fans provided, the more intense the heat removal and the higher the efficiency of the cooling system (ceteris paribus, of course). On the other hand, the noise level increases noticeably, and there are “multi-fan” stands, respectively.

The diameter of the fans also plays an important role. The larger the fan, the more advanced it is considered: a large diameter allows you to create an intense airflow at relatively low speeds, which reduces the noise level compared to smaller options. On the other hand, the large size also affects the cost accordingly.

The highest rotational speed of the fans provided in the active cooling system of the stand (see above).

Rotation speed is one of the parameters that directly affects efficiency: the faster the fan, the more powerful airflow it creates and the more heat is removed. At the same time, only fans of the same diameter can be directly compared by speed. In addition, high rotation speed increases the noise level; therefore, comparatively slow but large fans are considered more advanced than small and fast ones with the same performance (see "Airflow").

The maximum airflow that a cooling fan can create; measured in CFM — cubic feet per minute.

The higher the CFM number, the more efficient the fan.

The maximum noise level produced by the stand during operation. This parameter is relevant only for models equipped with active cooling (see above) — in fact, this function is the only source of noise.

The lower this indicator, the more comfortable the use of the stand will be and the better it will be suitable for situations in which silence is important (for example, for working late at night when others are sleeping). At the same time, even in the loudest models, it usually does not exceed 40 dB — this is comparable to the noise of leaves on a tree in a light breeze; and cooling systems in many laptops can make more noise. Therefore, paying close attention to quiet laptop stands is only worth it if you are using an extremely quiet laptop and do not want to lose this advantage.

— Tilt adjustment. The ability to change the degree of inclination of the surface on which the laptop is installed. From a technical point of view, you can adjust the tilt in any stand — for example, by placing an object under one of its edges, or by holding it in your hands at the right angle; however, in this case, adjustment is implied solely due to the devices that are regularly provided for in the design — legs, folding supports, etc. This feature provides additional convenience — it allows you to adjust the location of the laptop keyboard at the most optimal angle, without using specific tricks for this.

— Height adjustment. The ability to change the height of the surface on which the laptop is installed. This function provides advanced customization options: you can set the optimal height (within certain limits, of course) right on the spot, without moving the structure to another surface and without placing additional objects under it. Height adjustment requires the use of special supports, and therefore is found mainly among tables (see "Type").

— Fan speed control. The ability to change the rotation speed of the fan installed in the stand with an active cooling system (see above). Due to the high speed, good airflow intensity is achieved, however, noise and power consumption increase accordingly, and it is far from always necessary to intensi...vely cool the laptop; at the same time, the "quiet" mode may not be effective enough for complex tasks with heavy loads on the system. Speed control allows you to adjust the operation of the fan depending on the current load. However, this must be done manually.

— USB hub. The presence of a USB hub in the design of the stand — a set of additional USB ports. This feature can be quite relevant given that USB is the most popular modern standard for connecting peripherals, and even one dedicated to powering the cradle can significantly limit the laptop's ability. The hub (splitter) helps to correct the situation. There are models with both one outlet and more advanced ones with four.

— Place for the mouse. The presence in the design of the stand space for placing a computer mouse; it can be either a separate additional shelf next to the main platform (often removable), or a part of the platform / tabletop that is not intended for a laptop. Anyway, this function will save you from having to look for a suitable flat surface to work with the mouse; and in some models it is even possible to choose the side for placing the shelf — under the right or under the left hand. Most mouse pads are tables (see "Type").

— Laptop holders. The presence in the design of the stand mounts for fixing the laptop. Thanks to such mounts, the reliability and safety of use are increased: the laptop will not fall off the platform even with a fairly strong shock, and in some models even when the structure is overturned. At the same time, when buying a model with this function, you should clarify the compatibility of the latches with your laptop model, especially if its size does not match the maximum diagonal stated in the specifications (see above).

— Built-in speakers. The presence in the design of its own built-in speakers; thanks to them, the stand can also play the role of an external audio system. However the quality of such columns in most cases is not very high; however, they sound louder than most built-in speakers, while not taking up extra space or creating unnecessary hassle during transportation (unlike traditional portable acoustics, not to mention full-sized ones).

— Drawer. The presence of a drawer at the stand — like those used in desks. The dimensions of such a box are usually small; however, it may well come in handy for storing various small things, such as personal records or external laptop media.

— Illumination of the case. The presence of a lighting system in the design of the stand. Usually, this function is purely decorative: it does not affect the functionality, but it gives the product a stylish appearance.

The colour of the illumination provided in the stand with the corresponding function (see "Options"). This nuance is useful for those who want to choose a stand for the design of a laptop or for the design of a computer desk.

Note that the ability to change the colour in this case is usually not provided. So if the characteristics indicate several options at once — for example, blue / green / red — this means that this model is available in several versions that differ in the colour of the backlight.

The number of USB inputs provided in the design of the stand. See "Optional — USB hub " for details on this feature.

The more such ports are provided in the stand, the more peripheral devices can be simultaneously connected through it to the laptop. At the same time, note that all ports of the hub are powered by one laptop USB connector and share the USB power equally. Thus, for high consumption peripherals (like external hard drives without a separate power supply) there may not be enough power when connected through a hub with 3-4 ports.

The material from which the main element of the stand is made is the platform where the laptop is placed. The material of the legs (if any, see "Type") may vary, but this is quite rare.

— Plastic. The advantages of plastic are low cost, low weight, an abundance of possible shapes and colours, as well as strength that is quite sufficient for most cases. At the same time, it loses to metal both in terms of reliability and thermal conductivity — in other words, it removes heat less efficiently. As a result, this option is found mainly among inexpensive coasters.

— Metal. Most metal models are usually made from aluminium alloys. Such alloys are quite light, while they are significantly superior to plastic both in strength and in the quality of heat removal. The main disadvantage of the metal is a rather high cost, so it is found mainly in models of the middle and upper price range.

— Metal / plastic. Platforms that combine both materials described above in the design at once. Mostly these are models with active cooling (see above): a metal grill is made in them, on which the laptop directly stands and under which fans are placed, and the platform frame is made of plastic. This makes it possible to somewhat reduce the cost, while retaining the main advantage of metal platforms — the high efficiency of heat dissipation.

— Tree. This m...aterial for laptop stands can be attributed to the "designer" options. Wood has an attractive appearance, and is also considered more pleasant to the touch than other materials. At the same time, from a practical point of view, it has no noticeable advantages over plastic, it costs significantly more, and loses to metal in terms of heat removal efficiency. Therefore, it is worth paying attention to wooden coasters if style and aesthetics are in the first place for you, and the quality of cooling does not play a decisive role.

— Textile. A rather non-standard material for laptop stands, which, nevertheless, has its own advantages. So, some fabric coasters look like soft rugs, which can be compactly folded for easy storage and transportation during non-working hours. Such material passes air and heat well (manufacturers select the appropriate types of fabric), is quite pleasant to the touch, and looks good. Among the shortcomings of the fabric, it is worth noting the difficulty in cleaning — if it is enough to wipe the plastic or metal surface with a damp cloth, then the fabric stand will have to be washed (if such a procedure is generally allowed for this model).
