Deal context and Prime Day timing

Amazon Prime Day 2026 runs from Tuesday, June 23 to Friday, June 26, a schedule shifted earlier than the usual July window. The XKM01 Pro is discounted by 25%, dropping from its regular price of $99 to $75, a notable saving for remote workers. ZDNET applies a sliding‑scale rating system based on discount percentage, reviewer expertise and product recognition to curate Prime Day offers.

Product specifications and ergonomics

When folded, the keyboard measures 8.46 inches by 4.68 inches and features aluminum hinges that snap open for full‑size use, with rubberized stops that keep it flat on any surface. It includes a full numeric keypad, function row and a backlight that replaces the laptop stand found on the more expensive CaseUp Combo. The accompanying case is the same size as the CaseUp Combo, housing the keyboard, a small mouse, a smartphone stand and a USB‑A to USB‑C charging cable.

Compatibility and connectivity options

The XKM01 Pro works with Windows, macOS, Chrome OS, iPadOS and Android, allowing seamless switching between devices via a single keypress on Bluetooth 5.1 or through the included USB‑A dongle for 2.4G connectivity. The mouse offers adjustable DPI settings of 1000, 1600 and 2400 and provides silent clicks, making it suitable for quiet environments such as coffee shops or hotel rooms.

Battery performance and charging convenience

ProtoArc advertises up to 150 days of standby for the keyboard and 200 days for the mouse, meaning a single charge can last through multiple business trips. The devices charge via USB‑C, and users typically charge them once after each journey, reducing the need for frequent top‑ups while traveling.

Market positioning and competitor comparison

Compared with the pricier CaseUp Combo, the XKM01 Pro offers a more affordable entry point while retaining a full‑size layout and essential travel features. Although the 25% discount is not the lowest price seen, the limited‑time Prime Day availability creates urgency for digital nomads and frequent travelers. ZDNET continues to monitor the deal to ensure it remains live and updates readers on any stock changes.
