The buying question

Which setup fits your routine: a folding keyboard with a charging plan, or a fixed cradle keyboard with replacement cells?

XK01 folds for packing but needs suitable charging equipment. K780 keeps a device cradle attached to its fixed body and needs replacement batteries.

Quick verdict

When the recommendation changes
  • If your travel power kit has only USB-C-to-C cables, resolve XK01 charging before buying.
  • If the keyboard stays on one desk, folding storage may matter less than where your phone or tablet will sit.

The differences that matter

Mobile Setup Geometry

ProtoArc XK01 (Black)

Three-section folding keyboard body.[1]

Logitech K780 (920-008025, Dark Grey/Speckled White)

Fixed keyboard body with an integrated rubber phone/tablet cradle.[3]

What this changes: Choose the XK01 when folding the keyboard for packing is central to your setup. Choose K780 when a built-in place to prop your device matters more than folding storage. Check bag space and device support separately; this does not establish carrying comfort or that the XK01 lacks a stand.[1, 3]

The better fit depends on your priorities

Power Replenishment Workflow

ProtoArc XK01 (Black)

Rechargeable battery; ProtoArc specifies a USB-A-to-USB-C charging cable.[1, 2]

Logitech K780 (920-008025, Dark Grey/Speckled White)

Two replaceable AAA cells, accessed under the battery cover.[4]

What this changes: Plan a compatible charging cable and power source for XK01, or replacement cells for K780. A USB-C-only travel kit needs an extra check before choosing XK01; neither power method establishes longer endurance.[1, 2, 4]

The better fit depends on your priorities

Limitations

  • No hands-on comparison establishes typing feel, noise, connection reliability, battery endurance or hinge durability.
  • XK01 advice covers the standard Black number-pad model, not XK01 TP, Plus, UK-layout versions or mouse bundles. K780 advice covers English US part 920-008025, not plain-white part 920-008149.
  • Exact bag fit and XK01 stand arrangements remain unverified. Check your intended device-and-case fit before relying on the K780 cradle.

Questions shoppers ask

Will I give up the number pad or a third device channel by choosing the folding model?

No. Both provide a number pad and switching among three devices; those shared features leave packing and power preparation as the more useful deciding factors.

Can I assume my USB-C laptop charging cable will charge the XK01?

No. ProtoArc specifies USB-A-to-USB-C charging for XK01. Verify the cable and power source you plan to carry rather than relying on the connector shape.
