Logitech G613 vs Corsair K63 | Wireless Keyboard Review

Wireless keyboards have existed for a long time, since 1983 believe it or not. Mechanical wireless keyboards, on the other hand, are pretty new to the gaming market. Logitech and Corsair have taken the leap and have both released their own wireless mechanical keyboards. On this page, I’ll be comparing the Logitech G613 vs the Corsair K63. Both of these keyboards share the same goal but have ended up with fairly different outcomes.

Quick review: Logitech G613

In order to not release a mediocre product, Logitech waited until they had wireless technology mastered before creating the G613. This has clearly paid off as the keyboard is wireless, mechanical and has up to 18 months of battery life. Logitech have an amazing reputation for their gaming peripherals, their webcams, mice, and keyboards are extremely popular.

Both the wireless and Bluetooth connections from the keyboard are encrypted. Encryption is extremely important for wireless products in order to keep your information safe from hackers.

If you want a fully wireless setup, the Logitech G603 is a mouse that uses the same lightspeed wireless technology as the G613 keyboard.

Battery life

I first thought I had misread the specs when I saw the battery life was 18 months long, but it’s true, with only two AA batteries the battery should last up to 18 months. To achieve this long-lasting power, the Logitech G613 has no backlighting whatsoever. No backlighting could definitely be a deal-breaker for many people, when spending this much on a keyboard you kind of expect the usual lighting options.

Logitech have stated that having backlighting would decrease the battery life down from 18 months to 40 hours. I personally would rather have to never worry about battery life than have backlit keys.

Keyswitches: Romer G

The G613 uses Romer G tactile switches and claims they’re ideal for competitive gaming. These switches have a tactile bump and an actuation point of 1.5mm, this gives them a combination of speed and precision. The tactile bump on each key does make them louder than any linear key would be. While they may be sponsored, a lot of professional players do use keyboards with the Romer G tactile switches, this is a good sign of quality. If you don’t mind louder keys and enjoy having a tactile feedback to your keypresses, then these keys will suit you well.

Size and layout

The keyboard is pretty large which is strange for a wireless product. It has the standard full-size layout along with 6 extra buttons on the left of the keyboard, as well as a few media keys. The wrist rest at the bottom provides extra comfort while typing, unfortunately it cannot be removed which adds to the size and weight.

The G-KEYS on the left side are 6 quickly accessible keys which can be bound to any action you like. Having extra keys like this is great for MMO games that require tonnes of keybinds like World of Warcraft. Gaming aside, you could also bind these G-KEYS to useful shortcuts in editing programs like Photoshop.

You can find the media keys at the top right of the keyboard. There are volume controls including a button for muting your microphone. To the left of the media keys are the wireless options, including the lightspeed button and a Bluetooth button. Pressing the lightspeed button will enable Logitech’s lightspeed wireless mode, which will switch it to a super-fast 1ms report rate.

Bluetooth connectivity

You can connect the keyboard to other devices using the Bluetooth button to the left of the media keys. Using the Bluetooth button you could switch from typing on your computer to typing on your phone in a matter of seconds. Logitech even include a phone stand with the case to promote this idea.

Logitech Gaming Software

Using the Logitech Gaming Software you can set up and customize individual profiles for the keyboard. This is where you’ll be setting any extra keybinds and macros you may want. You can use this software to check the battery status, some people have complained that the way they display the remaining charge is not very precise.

Quick review: Corsair K63

After the success of the original K63, Corsair decided to release a wireless version. The keyboard is fully mechanical, wireless and has a TKL layout. Corsair keyboards are extremely popular amongst both casual and high-level players, the K63 definitely holds up to their usual standard.

As it’s a wireless keyboard it will cost you significantly more than the wired version. Although the keyboard is pretty expensive, combining the K63 with Corsair’s lapboard makes going wireless pretty tempting.

You don’t have to worry about any hackers tracking your keystrokes as both the wireless and Bluetooth connections have strong encryption. Knowing this you can use your keyboard out and about in peace.

Battery life

The keyboard will last 15 hours with full lighting, 25 hours with minimal lighting and up to 3 days with no lighting. This is a drastic difference to Logitech’s 18-month charge… and it makes you wonder how there could be such a difference. The short battery life comes down to the backlighting on the keys. Logitech even stated that for their G613, adding lights would have cut the battery life from 18 months to just 40 hours.

Corsair’s K63 is charged by cable rather than using batteries, this means it can be used both wireless and wired which is a great bonus. One problem with Logitech’s G613 is that if you run out of charge and can’t find batteries you’ll be out of options.


All of the keys are fully mechanical with Cherry MX Red switches. The Cherry MX Reds are one of the most popular mechanical switches for gaming keyboards. These switches are linear which means there is no tactile bump when pressing down the key, unlike Cherry MX Blues for example. Having no tactile bump is perfect for people who are looking for a quieter keyboard. The keys are expected to last for up to 50 million presses so you won’t have to worry about them wearing out.

Size and layout

The keyboard has a TKL layout which stands for tenkeyless, this is essentially a keyboard without the numpad on the right. TKL keyboards are cool because they’re compact and practical, most people have no use for the numpad so removing it makes a lot of sense.

There are extra buttons on both the top right and left of the keyboard including media keys and volume controls. You will also find a button to change the lighting and next to it a windows lock key, this key disables the windows button to negate misclicks. Due to Corsair aiming to create a compact keyboard, there are no extra mechanical keys on the keyboard, unlike the Logitech G613 which has the G-KEYS on the left.

The keyboard comes with a detachable wrist rest which can be attached to the bottom. It’s rubberized and should help with wrist comfort while typing or gaming for long hours. It’s nice that you can detach it as people may already own a wrist rest they like.

Corsair CUE software

Using the CUE software (Corsair Utility Engine) you can customize all of the usual things like keybinds and lighting. There’s an impressive number of lighting effects to choose from which you can freely switch in between. You can customize and set multiple profiles for different purposes whether they’re for gaming or other things like editing.

Corsair lapboard (sold separately)

The Corsair K63 has been designed to go perfectly with their gaming lapboard. If you’re looking for the ultimate living room setup then the K63 combined with the Corsair lapboard could be the combo for you. The lapboard is lightweight and comes with a built-in mousepad, the bottom is cushioned with memory foam for extra comfort. If your goal is to play PC games from your sofa then it could be worth the extra cost.

Reviewing the reviews (Amazon & Reddit)

Logitech G613 reviews


The Romer G switches have received a lot of great feedback, one person said they are a dream to type with and he loves the tactile clicks they provide. Everyone seems impressed with the wireless connectivity with no signs of glitches or disconnects. Although a bit strange, the free phone stand seems to be a fun surprise for a lot of people who bought the keyboard.


A few people were not impressed with the character quality on the keys, instead of printing the characters Logitech used stickers which was seen as lazy. The keyboard is pretty heavy and that combined with the non-removable wrist rest makes it a pain to carry around. Of Course, there were some complaints about there being no lighting, although I would brush this off as it’s the reason for the 18-month battery life.

Corsair K63 reviews


Buyers who bought both the keyboard and the lapboard love the combination for lazy gaming. One person said the keyboard has lasted for weeks without having to charge, although we don’t know how many hours they used it for. The backlighting gets an overall positive response, one reviewer on Amazon said it’s his keyboard of choice for the lighting alone.


The complaints about connectivity issues are hard to ignore, a worrying amount of people are very disappointed with the wireless performance of the K63. There is no responsive light for the caps lock key so you may unintentionally type in all caps. An Amazon review claimed the keycaps pop off easily and they have found that frustrating.


Both keyboards share the same goal but execute the challenge differently. Logitech have clearly spent more time focusing on the wireless technology as well as the battery life of the keyboard. On the other hand, Corsair have recognized the value of a wireless keyboard being compact and fit for laid back gaming. If you want perfect performance and to never worry about battery life, the Logitech G613 is the choice for you. If the size and weight of the G613 bothers you and you want to lay back and game from your sofa, the Corsair K63 may be a better choice.
