Ready-to-use mini PC stick

The Defendwe J4125 unit ships with Windows 10 Pro already installed on its 128 GB eMMC drive and 8 GB of LPDDR4 memory soldered in place. It is aimed at users who need a compact Windows device for digital signage, thin-client access or light office work without assembling parts.

Fanless aluminium chassis with versatile I/O

The stick measures 140 by 59 by 19 mm and weighs 137.2 g, using its metal body to dissipate heat silently. Daily connectivity relies on two USB 3.0 ports, one HDMI 2.0 output capable of 4K at 60 Hz, a 3.5 mm audio jack, a micro-card slot supporting cards up to 2 TB, and a Gigabit LAN jack alongside dual-band Wi-Fi and Bluetooth 4.2.

Celeron J4125 quad-core processor

The integrated J4125 runs at a base frequency of 2.0 GHz and can boost to 2.7 GHz across four cores, delivering enough throughput for 4K video playback and basic multitasking. Buyers who need higher sustained compute performance or discrete graphics should consider a larger mini PC instead.

Questions about this item

Does the HDMI 2.0 port on this J4125 stick PC actually deliver 4K at 60 Hz?

Yes. The HDMI 2.0 output on the J4125 model supports 4K resolution at 60 Hz, unlike the J3455 variant which is limited to 4K at 30 Hz via HDMI 1.4.

What are the exact dimensions of the PCG02 stick so I can confirm it fits behind my display?

The unit measures 140 mm long, 59 mm wide and 19 mm thick, weighing 137.2 g, so it tucks directly behind a monitor or TV without a separate mount.

How do I perform the one-step BIOS reset if the stick won't boot after a settings change?

Power off the stick, then press the BIOS reset button (usually a small pinhole near the Kensington slot) for a few seconds; the firmware will revert to defaults and auto-power on.
