MacBook Magnetic Charging Adapter

This USB-C to Magnetic 3 adapter brings MagSafe-style charging to compatible MacBook Pro 14 and 16 inch models from 2021 through 2025, plus MacBook Air M2 and M3. It supports up to 140W power delivery when paired with a suitable PD 3.1 charger and cable. The six foot length adds reach without extra bulk. Data transfer is not supported.

Zinc Alloy Build with LED Status

The connector shell uses zinc alloy with nickel-plated contacts for oxidation resistance and heat dissipation. A built-in PD smart chip manages the handshake. An LED ring shows orange while charging and green when complete, so status is visible at a glance. Magnetic alignment is strong enough to stay attached during normal desk use.

Replaces Lost or Damaged MagSafe Cables

This adapter upgrades a standard USB-C power brick into a magnetic charger, avoiding the cost of a full Apple cable replacement. The jump is worth it when the original cable frays or the brick remains but the MagSafe head fails. Buyers who need data throughput or want to charge non-Mac devices should look elsewhere.

Questions about this item

What USB-C Power Delivery standard does the 140W magnetic adapter use?

It requires a USB-C PD 3.1 cable and a 140W PD charger to reach the full 140W rate; a 20V/3.25A 65W or higher charger is the minimum for operation.

Which MacBook port does the magnetic tip fit?

The MagSafe 3 connector snaps onto MacBook Pro 14-inch and 16-inch models from 2021 through 2025 and MacBook Air M2/M3 models.

How do you set up the adapter for the first charge?

Plug a PD 3.1 cable into a 140W USB-C charger, attach the magnetic tip to the MacBook, and watch the LED turn orange then green — skipping the high-wattage charger is the common mistake.
