Comparison GamePro CP1450 vs GamePro CP870

The largest laptop screen size that the stand is guaranteed to be compatible with. For comparison: the smallest netbooks have a diagonal of 10 – 12 ", ultrabooks are somewhat larger — up to 14" ; among classic laptops, 13" corresponds to the most compact models, 15 — 16" — medium format, 17" — large, and 18.4" is actually the "ceiling" for modern laptops.

Usually, the maximum diagonal indicated in the characteristics corresponds to the size for which the stand was originally designed. However the vast majority of models are able to work with smaller laptops, but this point should be clarified separately. In addition, you should not buy a device that differs markedly in maximum diagonal from your laptop — for example, an 18" stand is unlikely to be convenient for a 12" netbook.

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").

Number of USB ports provided in the stand's design. For more details, see "Additional — USB Hub".

The more such ports the stand provides, the more peripheral devices can be simultaneously connected through it to the laptop. At the same time, it's worth considering that all the hub ports are powered by a single USB connector on the laptop and share the USB power equally. Thus, for "power-hungry" peripherals (like external hard drives without a separate power supply), there might not be enough power when connected through a hub with 3 – 4 ports.

Source of electricity for the functions of the stand that require power — primarily for the active cooling system (see above).

— From USB. Powered by computer USB port. The main advantages of this option can be called battery life and versatility. It is enough to connect the stand to the USB connector of the laptop installed on it — and it can be used regardless of the presence of sockets until the battery runs out, and if the laptop is powered by the network, then it is generally unlimited for a long time. Of course, you will need to use one USB port for use, but in many models this disadvantage is compensated by the presence of a USB hub (see "Additional"). But of the obvious shortcomings, one can only distinguish a decrease in the battery life of the laptop — after all, the stand also consumes battery power.

— From the network. Powered by a conventional household network 230 V. This option provides high power, which is more than enough even for the most high consumption cooling systems. On the other hand, it only works when there are outlets nearby and requires the use of a power cord, which creates inconvenience and limits mobility. Theoretically, the advantage of AC power is that it does not drain the battery of the laptop; however, in fact, this point can hardly be called significant, because. such coasters, by definition, are not designed for stand-alone use when you need to save battery. As a result of all this, mains power is very rare — mainl...y in the largest models.

Dimensions of the stand when folded. First of all, the convenience of transportation depends on this: if you plan to carry the product along with a laptop, you should pay attention to ensuring that the bag (case, backpack ...) has the right amount of space.

Note that the height of many models in the folded state is rather small, so manufacturers may not indicate it in the characteristics, limited only by the length and width.

The size of the surface intended for the direct placement of a laptop. This parameter allows you to fairly accurately assess how the stand is suitable for your device — after all, even laptops with the same diagonal can vary slightly in length / width.
