Customized taste - RK-H81 three-mode wireless hot-swappable mechanical keyboard out of the box

RK is considered a small factory of mechanical keyboards, and its products mainly follow the low-end entry-level cost-effective route, but now RK products are increasingly playing with their own style. On the one hand, it is to develop the design language of the product, and on the other hand, it is to customize Elements are added to the keyboard products, allowing users to have more functional experience. RK-H81 three-mode wireless hot-swappable mechanical keyboard has three colors, White Night, Ruyin, and Evening Star. The keyboard out of the box of the article is the white night version with white and gray black.

RK-H81 mechanical keyboard is a three-mode mechanical keyboard with 75% layout and 81 keys. The overall size of the keyboard is 335*142*40mm. The keyboard has a full-key non-conflict function, which is definitely helpful for gamers. .

The keycap of the keyboard adopts the PBT two-color injection molding process, and the keyboard as a whole is matched with three colors: white, gray white, and gray black. The keyboard style with multi-color keycaps has replaced the traditional single-color light-transmitting keycaps, and has a good performance in terms of overall appearance. Although the keycaps are opaque, the keyboard still has 16.8 million color RGB lights and supports multiple lighting modes.

The keyboard has a built-in 3760mah lithium battery. The official battery life data is 150 hours with the light on in Bluetooth mode and 12 days with the light off, and 180 hours with the light on in 2.4G wireless mode and 15 days with the light off. I don't understand the official data. It takes hours to turn on the lights and days to turn off the lights. If the calculation is based on 24 hours a day, then the Bluetooth mode can be used for 288 hours, and the 2.4G mode can be used for 360 hours. In this way, the battery life of the keyboard is quite long. Regardless of the limit factor, the average use is 5 hours a day for about 2 months before it needs to be charged once.

There is no function identification of the key combination on the keycap, so the function table is attached for user reference.

In the upper right corner is a 5-position rotary switch, through which the keyboard is connected, and the OFF position is connected through a USB cable.

The front end of the space bar on the keyboard adopts an inclined opening design.

The keyboard has 2 USB-C ports, the port marked by the computer on the right is the charging and wired connection port, and the U disk mark on the left is an expansion port, which can be inserted into the wireless headphone receiver in the USB cable connection mode, and the USB- C interface U disk and other external devices.

The receiver storage compartment is fixed by magnetic attraction, which is a simple and ingenious design.

The gap on the edge of the keyboard is relatively neat, only the corner gap in the picture is slightly larger.

The keycap of the keyboard is made of PBT material and adopts a two-color injection molding process.

The surface of the keycap is fine and grainy, and the PBT material is more wear-resistant and not easy to oil.

The large key position adopts the satellite axis scheme.

The feel of the large keys is relatively well tuned, and the sensuality of the keys is almost imperceptible. From here, we can see that the positioning plate of the keyboard is made of PC plastic material, and an integrated sandwich silicone pad is added under the positioning plate. There is also a layer of silicone sound-absorbing pad between the PCB and the bottom case, which can reduce the internal space of the keyboard when hitting the shaft. The resulting cavity reverberates.

The keyboard is equipped with TTC's colorful red switch (white night), which is a linear switch body, with a total stroke of 4mm, a trigger stroke of 1.9mm, a trigger pressure of 41gf, and a lifespan of about 80 million times. The axis body is suitable for text chat or code word articles. Compared with Kuaiyin axis, this axis body triggers slightly slower. When used in a relaxed state, the rhythm is easy to control.

TTC’s Colorful Red Switch (White Night) has a red axis and a white upper case, with a built-in condenser to increase the brightness of the keyboard’s lighting. The axis is still the traditional MX axis solution, and there is no dust-proof wall design. The shaft is lubricated at the factory, the up and down movement of the shaft is very smooth, and the bottoming sound is very solid.

The keyboard supports hot-swappable switches, and supports 3-pin and 5-pin switches. The LED lamp beads are attached to the back of the PCB and adopt a hole-opening scheme to support all RGB mechanical switches.

Because the keycaps of the keyboard are opaque, the lighting effect is weak after turning on the light.

The RGB light effect can only be seen through the gap of the keycap, but the keycap with light-transmitting function can be replaced later.

Summarize

Compared with its early products, RK's products in the past year have greatly improved in design, quality, and function. The small factory has played a customized taste in mass-produced keyboards. With this DIY feature, the color matching of the keyboard and the switch is also very coordinated. The TTC colorful red switch is a switch with different colors, and it is also to coordinate with the keyboard color system. It can be understood as a switch customized by the switch factory for the keyboard. The overall color matching of the keyboard is excellent. From the function point of view, the three-mode connection mode, RGB lighting, and full-key conflict-free, basically meet the mainstream needs of current players. The only difference is that there is no hardware macro editing function, but this function is rarely available. used. The keyboard supports hot-swappable switch. It can be said that you can play any switch you want to play. The switch is no longer limited to a certain keyboard. Even if there is a problem with the switch, you can repair and replace it yourself. The keyboard has a built-in 3760mah lithium battery, and the overall battery life is longer. I am more used to turning off the lights all the time, after all, the battery life can be longer. TTC colorful red switch (white night) button life can reach 80 million times, the reliability of the button can be well guaranteed, but the life of the switch body will be greatly reduced when used in a humid and dusty environment. The slight disadvantage of the keyboard is that the gap between the upper and lower shells is slightly larger at one corner, and it can be done better by improving the mold precision later.
