ASUS releases a new wired and wireless keyboard called ROG Falchion, this actually has a built-in battery. The keyboard is paired with CHERRY MX red switches.

The announcement dates back to July 2020, but not it's available. In addition to wired connection, it supports 2.4GHz RF connection with low latency. The main unit has a built-in 4,000mAh battery that can be used for up to 450 hours (when RGB is off). 

The "65% form factor in minimalist settings" incorporates arrows and navigation keys into a 65% keyboard layout for a 60% keyboard size finish. The length is 306 mm, the width is 101 mm, the height is 38 mm, and the English layout key is the CHERRY MX red axis 68 key. ROG PBT Double Shot Keycap suppresses wobbling, and by optimizing the mid-height keycap and short stem, it achieves both a superb touch feeling and high durability. The left side is equipped with an interactive touch panel. Volume control, application switching and shortcuts can be registered. It can also be used as a macro key to assist game operations. In addition, it is equipped with wireless Aura Sync RGB lighting, so you can enjoy the lighting effects.
