This might be the best accessory for professional travelers – and it absolutely changed the way I work on the go

This might be one of the best accessories for travelers and business professionals working on the go that we’ve ever reviewed, and the ProtoArc XKM01 CaseUp is now just $100 on Amazon.

In the US, a bundle which includes the keyboard, case, and mouse (but no laptop stand) was $80, but is now $64 at Amazon – and in the UK, this version is currently priced at £57 on Amazon.

And either way, you get an awesome set of portable peripherals for the price. The bundle includes a full-sized foldable keyboard, mouse, collapsible laptop stand, USB cable, and a case – effectively, every essential a productive traveler needs, except the laptop itself.

The CaseUp comes in three styles – black, silver and black, and space grey. We recently tested out this set, with our reviewer declaring it changed the way he works at home and away – with its compact and minimalist style really standing out.

We were impressed with the overall performance of this bundle – and as far as I’m concerned, the best part about the set is the tri-fold keyboard.

Unlike many portable keyboards (and even a lot of laptops), it’s a full-sized model, so it includes a row of Fn keys and a numpad, which I feel absolutely essential for business professionals.

In use, this keyboard was surprisingly comfortable and easy to type on, even for extended writing sessions. Keycaps are sized at 16.5mm, scissor-switch style – so relatively quiet, but definitely not silent. Key depth travel is somewhat shallow at around 1.3 mm, which is in line with a laptop like the Acer Aspire 5 and deeper than a MacBook Pro.

The laptop stand is very practical, and we found it worked well for tablets and even larger laptops. It’s fair to say the mouse is a pretty standard office mouse. Sure, it feels good and it’s responsive, but if you’re coming from a higher-end model like the MX Master 3, you’ll notice the difference. However, it undeniably gets the job done.

I don’t know about you, but stashing a mouse is one of my biggest bug-bears when using a mobile office since they’re often too bulky to properly fit into my laptop case.

For me, that’s the real highlight here. Individually, every piece of the set is good, though not outstanding. But the fact that they all nestle nicely inside the case, offering serious portability and versatility, is an absolute game-changer for anyone looking for a quick way to create a comfortable mobile office and working on the go. We found it seriously helped elevate ergonomics and functionality.
