Apple Macbook Charger- 85W Power Adapter MagSafe -compatible

1

Power Output

85 watts, sufficient to charge 15‑ and 17‑inch MacBook Pros.

2

Connector Type

MagSafe (original / MagSafe 1) magnetic DC connector (L‑tip style for many units).

3

LED Indicator

The tip has an LED: amber/orange when charging, green when fully charged.

4

Input Voltage / Current

AC input of 100‑240V, ~1.5A, 50‑60 Hz. Works worldwide with the proper plug.

5

DC Output Voltage / Current

Typical output for many 85W MagSafe adapters is ~ 18.5V at ~ 4.6A for L‑style (non‑Retina) versions.

6

Compatibility

Works with 15‑inch and 17‑inch MacBook Pro models (pre‑Retina & some Retina depending on MagSafe version).

7

Polarity / Safety Design

Magnetic connector helps avoid damage: if cable is tugged, it detaches rather than pulling the laptop. This reduces strain on cord & port.

8

Charge / Sleep / Off Behavior

Adapter charges the battery even when the MacBook is off or in sleep mode.

9

Cord / AC Cable

Comes with AC cable; often includes either a wall plug or extension “duckhead” and cord for length. The DC cable is permanently attached to the brick.

10

Portability / Design

The adapter brick is compact relative to its power; designed for travel. The cord is long enough to be practical. Sometimes includes cable wrapping design.

11

Durability Concerns

Common weak points are the cable near the DC connector and fraying at stress points. Using genuine Apple versions helps.

12

Warranty

Apple offers a 1‑year manufacturer warranty for genuine adapters.

13

Safety Features

Built‑in protections: against overcurrent, overvoltage, overheating. The magnetic connector reduces mechanical strain.

14

Original vs Compatible / Counterfeits

There are many “compatible” / third‑party options; quality and reliability vary. Genuine ones are more trusted. Fakes can have safety issues.

15

Usage Tips / Best Practices

— Avoid wrapping cord tightly around brick to reduce stress.
— Keep vent holes (if any) clear.
— Don’t let the connector or cable experience lots of bending or tension.
— If LED doesn’t light, check cable & connector contact.
— Use correct version (MagSafe 1 vs MagSafe 2) or adapter if needed. (General good practice.)
