Why Choose This USB4 Magnetic Adapter
Key Features
- Blazing 40Gbps Data Transfer – USB4 standard delivers up to 40Gbps bidirectional bandwidth. Transfer a 4K movie in seconds or edit 8K video directly from an external SSD without lag. Compatible with Thunderbolt 3, USB 3.2, USB 2.0.
- 240W Power Delivery (PD) – Supports high-power charging up to 240W (48V/5A). Fast-charge your 16-inch MacBook Pro, gaming laptop, tablet, or smartphone at their maximum rated speed when paired with a compatible charger.
- 8K@60Hz Ultra HD Video – Drive the highest resolution displays. Supports 8K resolution at 60Hz, as well as 4K at higher refresh rates. Single-cable solution for docking stations and external monitors.
- Magnetic Breakaway Safety – The magnetic connector separates cleanly when the cable is pulled or tripped over. Prevents your laptop from being yanked off the desk, saves USB-C ports from physical damage, and reduces wear on charge ports.
- Thunderbolt 3 Compatible – Works seamlessly with Thunderbolt 3, USB4, and standard USB-C devices. Backward compatible with USB 3.2, USB 3.1, USB 3.0, and USB 2.0 at their respective speeds.
Compatibility and Best Use
- Laptops and Ultrabooks – Perfect for MacBook Pro, MacBook Air, Dell XPS, Lenovo ThinkPad, HP Spectre, Microsoft Surface, Asus ROG, and any laptop that charges via USB-C. The magnetic breakaway adds safety on crowded desks or high-traffic areas.
- External SSDs and Storage – Connect USB4 or Thunderbolt external SSDs at full 40Gbps speed. Edit video directly from external drives without lag or buffering.
- High-Resolution Monitors and Docks – Connect to 8K, 5K, or 4K displays through USB-C DisplayPort Alt Mode. Ideal for video editors, graphic designers, and gamers using high-refresh-rate monitors.
- Tablets and Smartphones – Charge and transfer data on iPad Pro, iPad Air, Samsung Galaxy Tab, and flagship Android phones that support USB-C fast charging and data transfer.
- Gaming Handhelds – Steam Deck, Asus ROG Ally, Lenovo Legion Go – add magnetic breakaway protection to your charge port to prevent damage during mobile gaming.
Usage and Installation Tips
- Keep both magnetic contacts clean – The magnetic connector works best when both the adapter and the cable tip are free of dust, lint, or debris. Wipe with a dry soft cloth if connection becomes intermittent.
- Insert fully for proper connection – The magnetic adapter requires a firm “click” to ensure metal-to-metal contact. A loose connection may result in slow charging or data errors.
- Use with high-quality cables – To achieve full 40Gbps and 240W performance, pair this adapter with a certified USB4 or Thunderbolt 3 cable (not included). Standard USB 2.0 or 3.0 cables will limit speed and power.
- Check power source compatibility – While the adapter supports 240W, your charger and cable must also support USB-C PD. Most laptop chargers are 65W-140W – the adapter will work at whatever wattage your charger provides.
- Remove before packing – When not in use, detach the magnetic tip from the cable or unplug the adapter from your device. The magnetic tip can fall off and get lost if left attached to the cable in a bag.

- Retail package (small box)
- Note: USB-C cable is NOT included – this is a magnetic adapter only
Warnings and Safety Notes
- Performance depends on your cable and devices – To achieve true 40Gbps, 240W, and 8K video, you MUST use a certified USB4 or Thunderbolt 3 cable (not included). A standard USB 3.0 cable will limit speeds to 5-10Gbps and power to 60-100W.
- Not certified by USB-IF – This adapter is not officially certified by the USB Implementers Forum or Intel for Thunderbolt. The claimed speeds are theoretical maximums. Actual performance may vary based on device, cable quality, and environmental factors.
- Magnetic strength – The magnetic connection is strong enough for desk use but may disconnect if bumped hard or if the cable is tugged. This is by design to protect ports, but do not use in high-vibration environments.
- Keep away from credit cards and magnetic media – The adapter contains strong neodymium magnets. Keep away from credit cards, hotel key cards, hard drives, mechanical watches, pacemakers, and other magnetic-sensitive devices.
- No data transfer while disconnected – When the magnetic connection is broken, data transfer stops immediately. Do not use for critical file transfers where interruption could cause data corruption.
- Check for proper fit – Some laptop cases or phone cases may be too thick for the magnetic tip to fully insert. Remove cases or use a short extension cable if the adapter cannot fully seat.
- Heat dissipation – The 240W power delivery can generate heat during extended high-wattage charging. The adapter may become warm to the touch. This is normal. If it becomes hot, disconnect and check your cable and charger.
- Not for medical or industrial equipment – This adapter is designed for consumer electronics only. Do not use with medical devices, life-support systems, or industrial control equipment.
- Keep contacts clean – Dust, lint, or corrosion on the magnetic contacts will increase electrical resistance. Clean with a dry soft cloth or electronic contact cleaner if performance degrades.
- Do not disassemble – The magnetic adapter contains sealed electronic components. Disassembly will void any warranty and may expose you to small magnets that pose a choking hazard.
