SURGKET 85W Mag 2 MacBook Charger – 85W T-tip Adapter

The SURGKET 85W Mag 2 Power Adapter is a magnetic T-tip replacement charger that provides full-speed 85W charging for compatible MacBook Pro 15" Retina and backward-compatible 13" MacBook Pro/Air models (2012–2018).

Whether you lost your original brick or need a spare for travel, this SURGKET 85W adapter mirrors the output and protections of Apple-style adapters while adding a compact foldable plug and a safety-release magnetic connector. It supplies DC 20V at 4.25A, includes a smart protection chip, and shows charging status via an LED so you always know if your MacBook is charging or fully charged.

Which MacBook models will this adapter safely power?

This adapter is engineered for MacBook Pro 15-inch Retina models from mid-2012 through 2017 (including A1398 and A1424) and also works with older 13-inch Retina MacBook Pro and 13" MacBook Air models that use the magnetic T-tip connector. It replicates the charging behavior of the original 85W supply for supported machines.

• Full compatibility: MacBook Pro 15" Retina Mid 2012–2017 (A1398, A1424).
• Backward support: MacBook Pro 13" Retina and MacBook Air 13" models using T-tip connectors (2012–2017).
• Not compatible with Apple Silicon Macs (M1–M4 series) or pre‑Mid‑2012 models.
• Provides the same 85W output to maintain expected charging rates and power management.

How does the magnetic T-tip protect my laptop and cable?

The magnetic connector detaches when stressed, lowering the chance of your laptop being yanked off a desk and reducing strain on the cable termination. That breakaway behavior also helps preserve the adapter’s connector and your MacBook’s charging port over time.

• Safe disconnect: magnet releases under tension to prevent sudden pulls.
• Durable cable: less mechanical stress at the connector extends cable life.
• Polarity and fit: T-tip design matches original-style Mag 2 plugs for secure contact.

What built-in protections and indicators does the charger include?

The adapter incorporates a smart chip that monitors for over-current, over-voltage, and short circuits to protect both the charger and your MacBook. A two-color LED gives a clear, immediate readout of charge state so you can tell at a glance if the MacBook is charging or fully topped up.

• Smart protection: built-in circuitry for over-voltage, over-current, and short-circuit defense.
• LED status: amber when charging, green when fully charged.
• Worldwide input: AC 100–240V, ideal for travel with appropriate adapters.

What’s included, and how does SURGKET support customers after purchase?

The package contains one 85W magnetic T-tip power adapter with the attached cable and plug; every unit undergoes quality checks before it ships. SURGKET provides 24-hour online customer support to help troubleshoot issues and offers follow-up service if a problem arises.

• Package contents: 1 x 85W magnetic T-tip adapter with cable included.
• Quality control: each charger is tested before shipment.
• Support: online customer service available 24/7 for assistance and replacements.

Who is this for? This SURGKET 85W Mag 2 adapter is aimed at owners of mid‑2012 to 2017 MacBook Pro 15" Retina users who need a reliable, full‑power replacement or spare charger, and for users of older 13" Retina MacBook Pro or 13" MacBook Air models that still use the magnetic T-tip. It’s a practical choice for students, professionals, and travelers who want a compact foldable plug, clear LED charging status, and the safety benefits of a magnetic breakaway cable. Note: do not use this adapter with 2021–2025 Apple Silicon (M1–M4) Macs or pre‑mid‑2012 models.
