Magtame USB4 Cable 240W (USB-C to USB-C) 3.3ft with magnetic self-winding and up to 8K@60Hz
Product description
What it is (and what it’s for)
This Magtame USB4 cable is designed to do more than just move charge from one USB-C plug to another. On paper, it targets two common needs at once: fast power delivery (claimed up to 240W with 5A/48V fast charging) and video/data performance for modern USB-C devices. It’s also built around a magnetic self-winding design, aimed at keeping your desk or bag organised instead of turning into a cable spaghetti situation.
If you’re shopping for a USB-C cable for a hub/dock setup or for connecting a laptop to a display, this is the kind of spec-led cable that tends to appeal to people who actually use their ports for more than slow charging. Still, it’s worth tempering expectations: high-end performance claims only hold if both your device and the display/output path support the same USB-C standards and modes.
Key takeaways at a glance
What makes this cable stand out isn’t just the headline numbers. It’s the combination of:
- A magnetic, auto-organising approach to winding and storing
- USB-C to USB-C connectivity, aimed at USB 4/USB4-class use
- Video support up to 8K@60Hz (with the usual caveat that your device must support Alt Mode)
- Data transfer speeds claimed up to 20Gbps
That said, the length (3.3ft) is short enough that it suits a desk or a nearby dock connection, but it may feel restrictive if you want cables reaching across a room.
What you’ll notice day to day
Using it in real life is mainly about convenience and reduced friction.
The magnetic self-winding mechanism is the headline for day-to-day satisfaction. Instead of manually wrapping a cable every time you pack it away, you get a more streamlined “grab it, wind it, go” flow. That can be genuinely useful if you travel with a laptop, use a monitor on a stand, or constantly switch between charging and docking.
Example: if you’ve got a laptop on a small desk and you connect it to a USB-C hub for a monitor and peripherals, you’ll typically end up with one cable that lives in the setup. A self-winding design won’t replace cable management entirely, but it can keep the storage side from becoming an afterthought.
One limitation to keep in mind: auto-coiling designs can be more sensitive to how the cable is handled (for example, sharp twists while loose). The spec won’t tell you how it will feel for your exact routine, so it’s sensible to check whether you prefer traditional braided cables over mechanical winding systems.
Video and data: where the claims matter
The cable is presented as supporting:
- Video output up to 8K@60Hz when using the USB-C port for video output
- 4K@144Hz
- Alt Mode is mentioned for video output compatibility
- Data transfer up to 20Gbps
The important bit here is compatibility. Even with a cable that supports high bandwidth on paper, your device must support the necessary Alt Mode and the display chain must be able to handle it. If you have an older laptop docking setup or a monitor that doesn’t accept the right USB-C video mode, you may not see the top-tier refresh rate/resolution advertised.
Also, if you’re buying mainly for “works with everything” reassurance, this is where you may want to double-check the specific capabilities of your phone/laptop and any dock/hub you plan to use with it.
Tech specs (from the provided details)
- Type: USB4 cable, USB-C to USB-C
- Power delivery: up to 240W (5A/48V fast charging claimed)
- Length: 3.3ft
- Video support: up to 8K@60Hz, 4K@144Hz mentioned
- Data transfer: up to 20Gbps
- Design: magnetic self-winding
- Material: nylon braided
There’s also a marketing claim about fast charging (charging a “15 up to 86% in 35 minutes”). That sort of statement is useful as direction, but it still depends heavily on the exact device, charger power, and whether the full charging negotiation is supported.
Who it’s for (and who should think twice)
It makes sense if:
You want a single USB-C cable for a USB-C hub/docking station workflow, and you care about tidier storage as much as performance. If your setup supports USB-C video output and you’re chasing higher refresh rates (where supported), this cable is built with that in mind.
It might not be the best choice if:
You only need a basic charge-and-go lead and don’t care about video/data throughput—because you’ll likely pay for features you won’t use. It may also not be a great match if your workspace needs longer reach than 3.3ft.
And if you’re expecting plug-and-play 8K/144Hz results across any device/monitor combo, it’s safer to assume the cable alone won’t guarantee those outcomes.
Compatibility, requirements, and what to verify before buying
Before you commit, it’s worth checking a few practical things—especially for video:
- Does your device support USB-C Alt Mode for display output?
- Does your dock/hub and monitor support the refresh rate/resolution you’re aiming for?
- Are you pairing it with a power source that can provide the claimed power levels (240W needs appropriate charging capability on the supply side too)?
The product listing mentions compatibility with iPhone 15 Pro/16 Pro Max and MacBooks. That helps, but it still doesn’t eliminate the need to verify your exact model’s port capabilities and what you’re connecting it to.
Pros
If you like a more “desk tidy” setup and want a cable that’s aimed at USB4-class charging, video, and fast data, the magnetic self-winding design plus the high bandwidth specs are the big reasons to consider it.
Final verdict
It’s a solid pick if you’re building a clean USB-C workspace and you want one cable that supports fast charging (claimed up to 240W) as well as high-end video/data capabilities like 8K@60Hz and up to 20Gbps. Worth considering if you regularly use a hub/dock and would genuinely benefit from less cable clutter.
Should you buy it? Yes, if your devices and display chain support the required modes (Alt Mode is specifically mentioned) and you’re comfortable with a shorter 3.3ft lead.
Better avoided if you just need a simple charging cable, need longer reach, or you expect the top refresh rate/resolution figures to appear automatically without checking your device and monitor compatibility.
Mini FAQ
Does it support video output?
The listing says video support is available up to 8K@60Hz and also mentions 4K@144Hz. It also notes that you should ensure your device supports Alt Mode for video output.
Is it USB-C to USB-C?
Yes. It’s described as a USB-C to USB-C cable.
How fast is the charging?
It’s claimed as “5A/48V type c fast charging” up to 240W, with an additional claim about a device charging up to 86% in 35 minutes. Exact results will depend on the phone/laptop and charger capabilities.
How is it stored?
It uses a magnetic self-winding design intended to keep the cable organised and reduce tangles.
How long is the cable?
The cable length is stated as 3.3ft, so it’s best suited to desk or nearby docking distances.
