Should you’ve ever toppled your cellphone, pill, or laptop computer by tripping over the ability cable, you most likely questioned why, oh why, the connector tip doesn’t have a magnetic security launch similar to what Apple has on its MacBooks and Microsoft on its Floor laptops.
However you’ve discovered an inexpensive answer: An $11 magnetic-tip adapter that attaches to any USB-C cable! Downside solved.
Sadly, whereas it looks like a no-name adapter off Amazon is a superb concept, there’s really loads of proof to counsel you’re placing your {hardware} in danger with them.
Among the many dangers cited by USB-C consultants are:
- The danger of static electrical energy discharge.
- Knowledge loss and efficiency degradation from digital magnetic interference from the uncovered POGO pins (the tiny steel pins that push out to make the contact).
- The danger {of electrical} arc harm throughout the pins in high-humidity environments.
- The potential for particles to brief out the uncovered magnetic pins.
- It’s not formally a part of the USB-C specification.
The final level could sound like a drunken sports-bar argument over an esoteric NFL rule, however it could really be the very best cause to not purchase a magnetic tip adapter.
Be careful for these magnetic connectors!
As USB-C was designed across the assumption {that a} USB-C cable can be plugged right into a USB-C port — not linked by a magnet — the engineers didn’t account for the unwanted effects. For instance, USB-C is designed to anticipate a laptop computer drawing 65 watts to all of the sudden have its cable unplugged and to reduce the danger of {an electrical} arc by reducing the ability in a set period of time.
All that engineering goes out the window while you connect a magnet to the tip of the cable, which could be indifferent far quicker. If energy continues to be flowing by means of the cable, the danger of an arc is elevated.
However, you say, “Apple and Microsoft use magnetic connectors on their laptops they usually’re completely secure.”
Sure they do (and Microsoft even has filed a patent on a USB-C magnetic connector that it hasn’t acted on but), however each machine makers have additionally presumably put the engineering work into their proprietary connectors and chargers to account for the danger of injury and knowledge loss from sudden disconnects — and have the cash to face behind the merchandise.

You might be unlikely to see that stage of engineering work from a tiny vendor cranking out $11 magnetic adapters. And when you’ll discover anecdotal stories of individuals saying they’ve had “no issues in any respect” utilizing these magnetic adapters, you can too discover loads of anecdotal stories of broken telephones and laptops from utilizing these adapters, too.
And people stories match the warnings of interference, and arcing to killed charging ports from steel particles sucked into the magnetized connectors.
Over on the Framework Laptop computer discussion board, one buyer posted their dangerous expertise with a magnetic tip adapter: “I purchased a type of magnetic USB-C cables and practically fried one thing in my laptop computer with static electrical energy on the uncovered plug. The laptop computer didn’t submit, and the blinking lights indicated a reminiscence failure with error code 00001110,” the particular person wrote. “The following day, it booted effective, which was odd. Reminiscence assessments point out no points. Warning signs that you’re about to fry one thing: The show will glitch or all of the sudden flip black throughout use.”
(The) answer is to take away the USB-C cable and its removable plug from the laptop computer,” the particular person wrote. “In fact, there are a couple of threads right here about magnetic USB-C cables and in them, they do warn you to not use them, however I didn’t understand it was a problem till it was too late.”
And over on the USBCHardware Reddit discussion board the place it’s been a pinned warning for greater than three years I discovered this report:
“I’ve a pocket book burned by an unintended magnetic connector detach being linked to a charger. Then I inspected the connector components with a magnifying glass to seek out out it was made superb method to stop such accidents. In truth, I can’t perceive how did it occur. However, however, the broken pocket book is the truth that can’t be denied. Since then I ended utilizing them and suggest the identical to my buddies.”
There are others to be discovered, as nicely, however we’ll cease our parental lecture. Finally it’s as much as everybody to resolve how comfy they’re with the danger of utilizing a magnetic adapter, and you must weigh the relative dangers of a broken port or laptop computer from tripping over the cable, towards killing your laptop computer, pill, or cellphone from utilizing an $11 magnetic adapter.
For me, I’ll move, however you’ll should resolve for your self the place you stand.
