JetKVM DC Power Control Extension, Remote DC Power On & Off for Jet KVM

If you're already using a JetKVM, this expansion is absolutely worth adding. It gives you the ability to remotely power on, power off, or force reboot a connected system without being physically present. I added it to one of my homelab systems, and installation was straightforward. It integrates cleanly with the JetKVM, and once configured, it's nice having both remote console access and power control in one place. That's especially useful when a machine locks up and software-based remote access isn't an option. Build quality matches the JetKVM itself, and the USB-C pass-through keeps cable clutter to a minimum. This obviously isn't a product for everyone, but if you're managing servers, lab equipment, or other unattended systems with a JetKVM, it's a worthwhile upgrade that adds a capability I was missing.

I misread the listing and thought this was a full KVM. It’s actually a remote DC power control module that works alongside a KVM over IP setup, letting you remotely power cycle devices like mini PCs or NAS units through the system. Because of that, I wasn’t able to really test its functionality in my setup. That said, the build quality is solid and it came well packaged. It feels like a well-made piece of hardware. It would be a great size for a mini-PC setup and has all the necessary ports for connecting. I would say it's a good value for the service it provides and it appears to be fully compatible with the JetKVM system. If this is something you specifically need for your setup, I wouldn’t hesitate to pick it up.

Does not work at all, should have returned it

I picked this up thinking it would be a simple way to remotely power cycle a device, but it’s important to understand that this is not a standalone product. This is actually an expansion module designed to work with a JetKVM system, so it requires additional hardware to function. On its own, it doesn’t provide remote power control unless it’s connected to that ecosystem. Once I realized that, the design made more sense. It appears well built and intended for more advanced setups where you already have a KVM-over-IP system in place and want to add power control as part of that environment. For someone running a lab, server rack, or remote system where full control is needed, this could be a useful add-on. For simpler use cases (like just wanting to reboot a single PC remotely), this is probably more than what’s needed and may not be the right tool on its own. Overall, it seems like a solid component for the right setup, but it’s definitely something to research beforehand to make sure it fits your specific use case.

If you’re running JetKVM with mini PCs or other DC-powered devices, this is one of those upgrades that just makes everything cleaner and more functional. Installation is quick and straightforward. It’s a simple setup, and if you’re already working with JetKVM gear, this will feel very familiar. Everything connects the way it should without any confusion. Functionality is excellent. Being able to control DC-powered devices in the 12V–20V range is a big plus, especially for mini PCs, routers, and similar hardware. It adds another level of control to your setup without needing external smart plugs or workarounds. The USB-C passthrough is a standout feature. Powering the JetKVM through the RJ-12 connection cable keeps everything internal and tidy. No extra cables hanging out, no clutter, just a clean and proper install. Build quality and design are solid. It feels like a well-thought-out accessory, not an afterthought. Everything fits cleanly and integrates nicely into a rack or compact setup. Value is very good. For what it adds in convenience, control, and cable management, it’s absolutely worth the price. Especially if you’re trying to keep a clean and efficient home lab. If you’re using JetKVM with DC-powered devices, this is a must-have. Easy install, clean setup, and reliable control. It does exactly what it’s supposed to and makes your whole setup better.

Easy to setup and use and wide compatibility. The DC power control box was everything I expected and more. I tested this using a 12v powered mini PC and had no issues. Setup is as easy as placing this box and included cable between your computer and the power supply. The DC power control box then hooks up to your JetKVM using the included RJ12 cable and when the DC power control box is connected to the 12v power source for the computer, it also receives power from this source, reducing the overall need for additional cables. In the JetKVM webUI, all you need to do is enable the module and its that easy to setup. Turning the system on and off via the DC Power Control box does take a few seconds. One important thing to note is that you will want to ensure wake after power loss is enabled in BIOS to get the best use of this box. Overall, this is a great value if you need remove power control for a 12v device.

This add-on makes managing remote machines a lot easier, especially for stuff like mini PCs or NAS units. Being able to turn power on and off through the same interface you already use for remote access is really convenient. Setup is pretty straightforward, just plug it into the right port and route the power through it. Once it’s running, it also helps reduce cable clutter since it can handle power delivery for the KVM setup itself. I like that it's easy to connect. Also, it’s a useful piece if you’re already using a remote KVM system and want simpler control without having to physically touch the device.

I’m already a big fan of my JetKVM, and this little module makes the setup even cleaner and more useful. The big win here is power control for DC devices. You route the device’s power through the module and then you can turn it on or off right from the JetKVM browser interface. That’s super handy for things like a mini PC, NAS, or other always-on gadget you may not actually want running 24/7. For me it’s useful in two ways: • Power savings – I can shut things down when I’m away instead of leaving gear humming along all week. • Security peace of mind – if something sketchy ever hit the network (looking at you, ransomware/crypto nonsense), being able to remotely kill power to a device is a nice “break glass” option. Another nice touch is that it powers the JetKVM itself through the RJ-12 connection, which reduces extra cables and wall adapters. The pass-through setup keeps things tidy and the included adapters cover the common DC barrel sizes. Overall it’s one of those accessories that seems simple but adds a lot of practical control to an already great tool. If you’re running a JetKVM and have any DC-powered gear nearby, this is a really handy upgrade.

This DC power control module is a specialized add-on for the JetKVM that allows for remote power management of mini PCs, NAS units, or other DC-powered hardware. It supports a wide voltage range from 12V to 20V and includes adapters for common 5.5mm barrel connectors. The unit is useful because it lets you toggle power directly from a browser, providing a way to save energy or remotely reboot a stuck device without being physically present. In my home lab, this is a great way to manage secondary nodes that do not have built-in power management. It also helps keep the workspace tidy by powering the JetKVM itself through the RJ12 connection, which removes the need for an extra USB power brick. It should be noted that the included RJ12 cable is quite short. While this limits how far the JetKVM can sit from the DC module, it is manageable since the board can be placed anywhere outside of a case. Overall, this is a useful accessory that adds a lot of control to a remote management setup. It is built well and the pass-through design makes the installation look clean. Even with the short cable length, the ability to remotely kill or restore power to DC gear makes it a strong addition to the JetKVM.

If you already have a JetKVM, this DC power control extension is a really useful add-on. It makes turning your machines on and off much easier, so you can power-cycle a mini PC or NAS from the dashboard rather than reaching for the device itself. That gives you a lot more control over a setup than you would otherwise have, especially for anything tucked away in a rack. The build quality is high and it feels well put together. The single-cable approach is a real plus, since it powers the target device and the KVM over the same connection and keeps the wiring tidy. For anyone running a JetKVM, it slots in neatly and makes remote management that bit smoother.
