MACHSWON Power Cable 3 m (9.84 ft) 1.35 mm x 3.5 mm DC USB to DC Power Cord
Product description
What it is
A USB to DC power cable designed for devices with a 1.35 mm x 3.5 mm DC input. It’s built to RoHS EU environmental standards and aims to deliver a stable power connection for everyday electronics such as desk lamps, small computers, power banks, and similar gear. This is not a power supply, but a cord intended to carry DC power from a USB source to a compatible device.
How it’s constructed
The cable uses a double-layer PVC sheath to resist pressure and provide durability, with a pure copper core advertised at up to 99.9% purity for low resistance and steady transmission. The outer jacket is described as elastic and environmentally friendly, with a soft PVC exterior that offers high rebound to mitigate core damage from bending. The plug is nickel plated to resist corrosion and rust, designed for repeated insertion and extraction, and the tail features reinforced three rings for added toughness.
Compatibility and use cases
This cable targets DC interfaces of 1.35 mm x 3.5 mm. It’s suitable for powering a range of small to medium devices including desk lamps, USB-powered lights, USB fans, small projectors, routers, and some notebook accessories that match the 1.35 x 3.5 mm connector. Before purchasing, it’s important to verify that the device’s power jack matches the 1.35 mm x 3.5 mm specification and that the USB source can supply the required current.
What stands out on paper
On paper, the combination of a high-purity copper core and a robust outer jacket suggests reliable, low-loss power transmission with reasonable durability. The three-ring reinforced tail and nickel-plated plugs are notable details for longevity in daily use and frequent plug-in cycling.
Limitations and caveats
No cable is universally compatible. The main limitation here is the connector size: 1.35 mm x 3.5 mm is not universal for all DC devices. The cable’s performance also hinges on the USB source’s ability to provide sufficient current—if a device requires more current than the USB port can supply, the device may not receive stable power. If you rely on high-power devices or need fast charging, this cable may not meet those demands.
Who this is for
This cable is likely suited to users needing a longer run (3 m) for a DC-powered device with the matching connector, such as a desk lamp or a compact peripheral that accepts a 1.35x3.5 mm input and is powered from a USB port.
Who should steer clear
If your device uses a different DC plug size or requires higher current than your USB source can provide, this cable would not be the best choice. It also isn’t a power supply or a kit that guarantees universal compatibility across all USB-powered devices.
When it makes sense to buy
Consider this cable if you specifically need a 3 m DC cord with a 1.35 mm x 3.5 mm plug, and you have a matching USB-powered device. The extra length can reduce clutter and give you flexibility in seating desks or workspaces.
What to check before buying
- Confirm the device’s DC input is 1.35 mm x 3.5 mm.
- Ensure your USB power source can deliver adequate current for the connected device.
- Consider the total length you actually need, 3 m is generous but may be unwieldy in compact setups.
Practical example of use
Imagine you have a USB-powered desk lamp placed away from the nearest power strip. A 3 m DC cable lets you position the lamp where you want without stretching or bending the cord, reducing strain on the connector and keeping the workspace tidy.
Brief comparison in context
If you’re weighing options, this cable sits between a basic short USB-to-DC lead and a higher-end, purpose-built power cord. It makes more sense when you need extra reach and the device shares the 1.35x3.5 mm connector. For high-current devices or different connector sizes, you’d likely look at alternatives with matching specs or a dedicated power adapter.
FAQ
- Is this a power supply? No. It’s a power cord designed to carry DC power from a USB source to a compatible device.
- Will it work with my device? Check that the device uses a 1.35 mm x 3.5 mm DC input and that your USB source can supply sufficient current.
- How long is the cable exactly? It measures 3 metres (9.84 feet).
Final thought
If you prioritise a longer, durable DC lead for a device with the exact connector size, this MACHSWON cable offers a pragmatic solution. It’s not the best fit for every device, but for the right pairing it reduces flexibility friction and keeps power transmission straightforward.
