List and recommendation of low-priced wireless bluetooth thin film keyboards of mainstream brands

As a thrifty trash guy, the primary consideration when buying something is price. As long as the basic requirements are met, some extra things can be sacrificed, such as feel, appearance, etc. Another thing to consider is the brand, which often represents the quality, the length of product life, and the quality of after-sales service.

The keyboard is a necessity. In the process of purchasing, I listed and compared 19 models. Because the price of mechanical keyboards is generally higher, and the typing sound is generally louder, so I chose the membrane keyboard. In order to keep the desktop clean and orderly, I'm more inclined to go wireless. Listed below are low-priced wireless membrane keyboards from mainstream brands with high sales volume.

Logitech can be said to be a well-known brand, producing countless classic keyboards and mice.

The first is the three brothers who are very popular: k380, k480, and k580.

Among them, the k380 is the smallest, with a length of only 27.9 cm. It is also a very controversial keyboard. The advantage is that it is portable and there are many colors to choose from. The disadvantage is that the keys are too compact, which many people cannot adapt to.

The k480 is the heaviest of the three, weighing 820g, 2 cm longer than the k380, and 7 cm wider than the k380, mainly because it is too wide and bulky, but it has an integrated bracket that can meet most Tablets and phones.

The k580 has a numeric keypad, and in addition to Bluetooth, it also supports 2.4G connection, but the number of devices that can be connected at the same time is 2, while the k380 and k480 are 3. The k580 also has an integrated stand, but it is much shorter than the k480, and the tablet is almost unusable.

Overall, I recommend the k580. Its length is 37.35 cm, which is equivalent to the length of my 15.6-inch notebook. The portability is still acceptable, and it has a numeric keypad, which is also a plus.

Logitech K375s is a full-size keyboard with a numeric keypad, the length is 43.55 cm, the connection method is 2.4G and Bluetooth, it can connect 3 devices at the same time, and it has a universal bracket, if it is used at home or in the office, it will not be carried out , is also a good choice.

Logitech K400 plus is a keyboard with a touchpad. When the TV in the living room is connected to the computer, you can control the computer and TV while sitting on the sofa. The connection method is 2.4G.

Shuangfeiyan is also a relatively well-known domestic brand, and has produced many classic models.

There are five types of non-suitable wireless membrane keyboards sold by Shuangfeiyan, FBK11, FBK25, FBK30, FBX50C, and FBX51C.

The connection methods of these five models are all 2.4G+Bluetooth, and the number of devices that can be connected at the same time is 4.

Among them, FBX50C and FBX51C are two built-in lithium batteries with a capacity of 300mAh, claiming that they can be used for office work for 5 months when fully charged. And the charging ports are all type-c ports, which is better. The three models of FBK are powered by dry batteries, of which FBK11 is powered by two AA batteries, and the other two models are powered by one AA battery.

FBK25 and FBX50C have numeric keypads, and they are also the two longer models among the five models.

Among the five models, I prefer FBK25, which has a numeric keypad and an integrated stand. The length of the keyboard is 39.6 cm, which is 2.25 cm longer than the Logitech k580, but it can connect two more devices at the same time than the k580.

Rapoo's wireless membrane keyboard is mainly the Blade series, with many styles, and some of the same model can be divided into 2020 version and 2023 version. The specific parameters are distinguished as follows:

Among them, E9000G, E9000G-2023 version, and E9050G do not have a numeric keypad, and the other five models all have a numeric keypad.

E9050G and E9350G have a built-in lithium battery with a capacity of 300mAh, and the charging interface is Type-C. The other six models are powered by 2 AAA batteries.

The main feature of the Blade series is thinness. The thickness of the thinnest part of each model is shown in the figure below, and the parameters of E9050G and E9350G are not found.

Rapoo also has a lower price k800, 2.4G connection, powered by a AA battery, compact 78 keys, if you are looking for the ultimate low price, you can also consider it.

All of the above are thin-film keyboards with prices below 200 yuan, most of which are 2.4G+Bluetooth connection modes, and can connect to multiple devices at the same time. From the parameters, we can see that the model powered by dry batteries has better battery life, so I still recommend you to choose models powered by dry batteries. The numeric keypad can be selected according to your needs. The model without a numeric keypad is more compact and portable, and the model with a numeric keypad will bring greater convenience to input. I am more inclined to choose a model with a numeric keypad. I am currently using Shuangfeiyan FBK11 without a numeric keypad. It is very inconvenient to input numbers every time. The input is slow and painful.
