It also means that the board is a decent (if not ideal) option for PC gaming, something that Bluetooth-only boards can’t boast. Combined with an absolutely massive 4,800mAh battery, it should last for months with the RGB lights turned off—I couldn’t drain the battery completely during my testing period. Use the original charging cable to connect the USB port of the computer for charging, and the charging current should be less than 1A.Update: I upgraded this to 5 stars because the brass plate is now available for the purple and white keyboard. In addition they added the Box Taro Ice Cream switch. Although I prefer the delete key at the top, this keyboard is worthy of the 5 stars. Then again, if you want to go for a completely different switch type, it’s entirely possible as the NJ80 is fully hot-swappable! You can fit any 2-pin switch you want, so the customization potential of this keyboard is very good. Stabilizers
The full ABS plastic body of the Keydous NJ80 comes with one color option: off-white. This gives the keyboard a pretty distinct retro vibe that I’m very much a fan of. But I understand if not everyone is a fan of the yellow space bar, baby blue escape key, and gold volume knob. The 4400mAh batteries sounds large, but in actual it is mediocre to below expectation. Tested on two cycles, the battery on average only last around 40 hours of usage with 2.4G mode and lights off. While charging (Using Original USB-C cable to PC) need around 7 - 7.5 hours to fully charge. There is a set of retractable rubber foot attached to the bottom housing and the rubber feet are on four corners of the keyboard. 2.4G dongle is kept in a groove/cut-out on the bottom housing. The on/off switch is located at the right side of the bottom housing to turn on/off the keyboard when using the keyboard wirelessly. Right from the get go, the Keydous NJ80 feels like a true premium product. Essentially, it’s a relatively compact 75% wireless keyboard with a clean, minimalistic design. It has a unique milky colorway with a dash of blue and yellow that’s really pleasing to the eye and feels like a great fit for a warmer, retro setup. Besides the beautiful color, the keycaps are made from really high-quality PBT plastic and have sharp, minimalistic font, and a really comfortable, uniform profile. Microsoft for Business CouponExclusive: 20% off select Surface Pro 9 for Business + Type Cover BundleWhile you might be tempted to use the Keydous NJ80 without a USB connection to your PC, you actually need one, if you want to customize the keyboard via the software. The software is very limited, with most of the options available on the keyboard itself, but you can reassign all the keys on the Keydous NJ80, with the exception of the volume knob and Fn key. The volume knob can only adjust the volume and mute it with a press. Keydous did a pretty good job with the keycaps, with sharp, precisely-positioned legends. These are Dye-subbed PBT keycaps, which are actually doing the RGB underneath an injustice. Yes, the Keydous NJ80 does have RGB LEDs, but as the board is South-facing, the LEDs won’t do that great a job of illuminating your regular shine-through keycaps, which often have the legends on the upper portion of the keycaps. The Keydous NJ80-AP is a 75% compact keyboard with wireless capability as a baseline. The version I received has the brass plate and the Gateron Pro Milky Yello Switches. The other option available for the plate is a steel one, and the main difference between the two is brass will muffle sounds a bit more and have a slightly heavier weight. The plate can also be seen clearly between the keys and when the keys are removed, so there is an aesthetic aspect to the choice between the two. The typing experience on this with the gat milky yellows is very creamy. I decided I would need at least a few mods to make it sound more to my liking, but honestly, it is perfect the way it is already. If you are a fan of linear switches then the gateron milky yellow switches are a great option. I am able to connect to my MacBook and PC relatively fast via Bluetooth. No input lag when using Bluetooth for office use, and it shows the battery percentage on the Bluetooth section of your mac. The battery lasts a decent amount of time when used wirelessly, and I am able to switch to my two devices as needed. Love that it came with 2 colored knobs, gold and silver, and also extra keycaps to make my keyboard all white, which matches my aesthetic more. Keydous claims the NJ80’s 4800mAh battery offers up to 28 hours of battery life with RGB on, and up to 90 hours with the RGB lighting off. In my testing, I didn’t find any reason to refute Keydous’ claims, as I never had the NJ80 die on me when I was using it.
The keycaps are high-quality PBT plastic, as seen on the best keyboards (and withheld from some of the stingier designs… Razer). In comparison, the case is a little underwhelming. It’s ABS plastic through and through, a rather dull white, and held in place with clips and very difficult to open. You could argue that it’s saving weight versus a more premium aluminum build, but this is already a pretty hefty board thanks to its premium interior components and a beefy battery. The original charging cable must be used to connect the USB port of the computer for charging, and the charging current should be less than 1A. While the PBT keycaps on the NJ80 are great, it doesn’t allow for any RGB shine-through if that’s your jam. The steel plate however does reflect the RGB well, resulting in an even glow throughout the keyboard. Switches Adjustable angle: Yes, with 1 step only (Flat: 4.2°, Raised: 6.2° - Measured manually by hand, might have slight error) Keep the Bluetooth receiver away from WIFI signal sources, handle the keyboard gently when inserting and removing the shaft body, and store the keyboard in a cool and dry environment when not in use.
One of the main reasons why I got the Keydous NJ80, aside from the fact that it had a volume knob, was the fact that it connected via 2.4GHz wireless. As we all know, Bluetooth is great for efficiency and pairing with multiple devices like smartphones, but 2.4GHz wireless has the upper hand when it comes to latency. I did test the Bluetooth connection on the Keydous NJ80, and while some Bluetooth 4.0 wireless keyboards I tested exhibited severe latency issues, to the point of being a whole word behind when I am typing furiously, the Keydous NJ80’s Bluetooth 5.0 played well with my ROG Crosshair VIII Hero (WiFi)’s built in Bluetooth, powered by the Intel Wi-Fi 6 AX200 adapter. WIFI signal interferes with Bluetooth signal to some extent, so bluetooth receiver cannot be too close to WIFI signal source. Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. I wasn’t sure how I would like the Gateron Pro Milkey Yellow switches at first because they seemed to have a lot more resistance than the ones I am used to. In use, they are smooth as butter. However, when writing long articles, I have a bit of finger fatigue from needing to press a bit harder than I normally do. However, these switches have quite a lot of springiness to them, making them feel good to use and increasing my typing speed a little bit. They are also incredibly quiet, which is an absolute requirement for me.
The fact that much more expensive, mass-market keyboards have worse feeling space bars shows the care Keydous put into perfecting each NJ80 they make. Software This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: If simply pressing down the volume knob to mute volume is getting too boring, you can also press Fn+10. In the same vein, you can press Fn+11 to decrease volume and Fn+12 to increase volume. The premium built-in Rogers INAOC Poron foams reduce unnecessary noise and hollow sound when typing on the mechanical switches. The foams are installed between the PCB and the plate, as well as at the bottom case, providing an enjoyable and sheer typing feel.Carefully selected PBT with 90% high concentration provides unique matte texture on the surface,like caressing soft sand. The high-end dye-sublimation printing technology produces sharp and clear legends that are not easy to fade or get oiled even with long-term use. The ergonomic Cherry Profile is not easy to cause fatigue with long time use. I do wish the volume knob was remappable as well, but alas it’s not. Being able to use the knob in applications like Photoshop or Premiere would give it a wide range of uses which would’ve turned the Keydous NJ80 into a productivity consideration. If you want to pair another device to the NJ80, follow the above steps; but when entering pairing mode, press and hold Fn + a different number from the one you initially used to pair the first device with. This lets you simultaneously pair multiple devices to the keyboard. You can then easily switch between paired devices by pressing Fn+1/2/3. 2.4Ghz Connection Most of the time I’ve been using the NJ80-AP, I’ve been switching between two Bluetooth devices and one on 2.4 G mode. The only issue I had with the switching was one time I forgot I had turned the keyboard off, so it took me a minute to realize why it wasn’t connecting. I had no issue with unexpected repeated letters while typing or any issue with using the WASD keys to move in games. Regardless of the connection type, everything was as good as when using a wired mechanical keyboard.
