Keychron K3

Although you'll have to pay extra for Keychron's $25 travel bag (or find another way to preserve the keys), the Keychron K3 has a lot to offer for on-the-go typists. There's a lot to appreciate about the Keychrom K3 with its enticing appearance, beautiful backlighting, slim design, and swappable low-profile switches. In terms of comfort, appearance, and adaptability, it's the greatest portable low-profile mechanical/optical keyboard. It's remarkable that Keychron was able to keep things so minimal while yet keeping the flexibility to shift switches.

However, you'll have to sacrifice battery life and overall frame stiffness in order to get the small package. If you have room in your back for a taller device, the Keycrhon K3 has greater battery life, feels tougher, and has longer battery life. So, before you buy, think about how much mobility you'll need.
