Description

🔌 Overview: What This Charger Is

The Japter 140W USB-C Mag-3 Cable Charger Power Adapter is a high-power, next-generation laptop charger designed to deliver fast, reliable charging to modern MacBook models and other USB-C PD-compatible devices. It combines a powerful 140-watt USB-C power adapter with a MagSafe 3 magnetic charging cable, allowing MagSafe-enabled MacBooks to snap on securely for efficient energy delivery.

It’s part of the class of PD (Power Delivery) 3.1 chargers, meaning it uses the latest USB-C charging protocols to intelligently negotiate power levels with the connected device for optimal speed and safety. Apple+1

⚡ Performance & Charging Capabilities

📈 High-Output Fast Charging

• Maximum Output: ~140 W (watts), which is the highest standard for USB-C PD chargers meant for large laptops.

• This high power output enables fast charging on compatible MacBooks — for example, Apple’s official 140 W USB-C adapter can recharge a 16-inch MacBook Pro from empty to ~50 % in about 30 minutes when paired with the correct cable. Apple

🔌 Power Delivery (PD) Protocol

• Supports USB-C PD 3.1, meaning the adapter and cable work together to communicate with your MacBook and deliver the right amount of power — scaling from lower levels for smaller devices up to the maximum safe 140 W for big laptops.

• PD 3.1 also ensures intelligent voltage and current negotiation, protecting against overcurrent and overheating.

🧲 MagSafe 3 Cable — Magnetic Smart Charging

📍 Magnetic Connection

• The Mag-Safe 3 cable has a magnetic connector that aligns with built-in MacBook charging ports. When the connector reaches the port, it snaps into place magnetically.

• This offers two main benefits:

  1. Secure connection during charging — your MacBook stays connected even if the cable gets jostled.

  2. Safety release — if someone trips on the cable accidentally, it detaches harmlessly instead of pulling your laptop off the desk.

📏 Cable Length & Build

• Many versions of this charger include a long (~6.6 ft / ~2 m) cable, giving you flexibility to use your device comfortably while charging.

• Cables are often nylon-braided or reinforced for durability, reduced tangling, and long life. Newegg

🔋 Charging Status LED

• Some MagSafe 3 cables include a small LED near the magnetic connector that shows charge status — amber during charging and green when fully charged. Ubuy Algeria

💻 Device Compatibility

This charger is designed for modern USB-C/MagSafe 3 devices, especially Apple laptops, such as:

🍏 MacBooks

Compatible with:

• MacBook Pro (14″, 16″) models from 2021 to 2023 with M1/M2 chips

• MacBook Air (13″, 15″) with M1/M2 chips from recent years

• Other USB-C/MagSafe 3 laptops that support PD (test locally) Ubuy Algeria+1

📱 Other Devices

• Works with many USB-C devices that use PD charging (phones, tablets, etc.), although full 140 W charging only applies to devices that support that power level via USB-C or MagSafe 3.

Important Note: Always verify your specific MacBook model supports 140 W charging via MagSafe 3; official Apple guidance shows that certain combos of adapter and cable are recommended to achieve fast charge. Apple Support

🔒 Safety & Protection Features

Good chargers in this class typically include a suite of protective technologies to keep both the adapter and your device safe:

• Over-current protection

• Over-voltage protection

• Short-circuit protection

• Thermal (over-heat) protection

These features help ensure stable performance and reduce the risks of damage from power surges or poor electrical conditions — especially important for high-wattage charging gear. Newegg

📦 What You Get in the Box (Typical)

While specific boxes vary by seller, a typical bundle will include:

• 140W USB-C power adapter (the main charging brick)

• MagSafe 3 magnetic charging cable (often ~2 m)

• Wall plug / prong adapter (depending on region)

Some versions may also include an additional USB-C cable for regular PD charging.

🧰 Practical Usage Tips

✔ Always check that your MacBook’s charging port and firmware support high-wattage PD charging.
✔ Use the magnetic cable firmly — the magnet ensures proper alignment every time.
✔ For fastest charging on big Pro models, this 140 W adapter is ideal.
✔ If charging smaller devices (phones/tablets), the adapter will automatically scale down power safely.
