With the development of science and technology, the performance of today's tablet computers has been catching up with that of notebook computers, coupled with its unparalleled portability, making more and more consumers regard tablet computers as the best choice for mobile office. Of course, before that we have to equip it with an external keyboard to make up for the disadvantages of touch screen typing.
How you connect is important
Bluetooth wireless transmission is a standard function of many tablet computers, and the Bluetooth function can be used to transmit data with other devices, and the external keyboard is no exception. Using Bluetooth as the connection method is the mainstream product on the market at present. It is not limited by data lines and various transmission interfaces. It can be connected with the Bluetooth hardware on the computer and has strong versatility.
Compatibility cannot be ignored
At present, the system programs used by tablet computers are divided into three types: Android system, windows system and IOS system. Different systems have different support protocols for external hardware.
There is a difference in battery life
External keyboards usually have a built-in battery to ensure daily use. The larger the battery capacity, the stronger the battery life. However, consumers are also reminded here that the increase in battery capacity will inevitably lead to an increase in the volume and weight of the product, which will affect the convenience of daily carrying. Looking at the mainstream products in the market, it is advisable to maintain the battery capacity at around 300~600mAH.
No need to deliberately pursue fancy design
In order to increase product competitiveness, many manufacturers will increase RGB button backlighting and multimedia control functions to attract consumers, but as an external device, its essential function is only to facilitate users to input content more conveniently, so some Fancy functions not only have no practical significance for actual operation, but will increase the cost of use, and are not very helpful to the actual use of users. On the contrary, some more practical functions, such as protective shells and support frames, are often more effective. When purchasing, users can consider it as appropriate.
