Max. screen size
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.
Noise level
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.
USB A interface
The USB port interface allows you to understand what speed the connectors have when connecting drives to them. So USB 2.0 is considered the most traditional option — an already outdated format, which nevertheless easily handles with connecting a mouse, adapters (Bluetooth, Wi-Fi) and other peripherals. Its transmission speed is up to 480 Mbps, which is not enough in today's realities. The more advanced
USB 3.2 gen1 has a similar connector format with improved bandwidth — up to 4.8 Gbps.
Table top/platform size
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.
Weight
The total weight of the stand. You should pay attention to this parameter first of all if you plan to constantly carry the stand with you, along with a laptop — here light weight can be a noticeable advantage. But if you are looking for an option purely for home use, there is most often no need to pursue low weight: other things being equal, it can be a sign of a small thickness of materials and, as a result, relatively low reliability. In addition, a more massive stand is more stable, it is more difficult to budge or knock over by accidental touch.
