140W PD Fast Charging – 60% in 30 Minutes

MacBook Pro 16" – up to 140W
MacBook Pro 14" – up to 100W (automatically negotiates safe power)
MacBook Air M2 – up to 67W
Charge your MacBook Pro to 60% in just 30 minutes. Perfect for busy professionals, students, and creators who need a quick top-up between meetings or classes.
Magnetic 3 Connector – Secure, Self-Guiding, Tangle-Free
The magnetic tip effortlessly snaps into your MacBook's MagSafe 3 port. No more fumbling in the dark or damaging the port from misalignment. The strong magnetic hold prevents accidental disconnection if you trip over the cable, saving your laptop from a fall.
5 gold-plated spring contacts – reliable power and data (if supported)
Self-aligning – connects on first try
LED indicators – red when charging, green when full
Built to Last – Braided & Tested
Braided nylon exterior – resists fraying, kinking, and everyday wear
Reinforced connector joints – withstand over 10,000 swing tests
Premium aluminum alloy housing – sleek, durable, and heat-dissipating
2-Meter Length – Freedom at Your Desk or Bedside
At 2 meters (≈6.6 feet), you have comfortable reach from wall outlets, power strips, or under-desk chargers. Long enough to work on the couch or in bed, but not so long that it becomes a tangled mess. Also available in 1M and 3M.
