Connection points are the electrical connections between electrical equipment and between them and busbars or cables. Overheating of the connection point is an old problem of the power system, but with the increase of the equipment load, the user's progress on the reliability of the power supply has become an increasingly prominent problem in the management of equipment defects, which deserves our attention. The reason for its development is to solve it completely.
1. Electrical equipment fever source. When the electrical equipment is working, due to the action of current and voltage, there will be three kinds of thermal faults such as resistance loss, fever, dielectric loss, and iron loss.
2. Thermal failure of electrical equipment. Thermal faults in electrical equipment can be classified into external faults and internal faults. Poor contact is an external fault of electrical equipment; various electrical bare joints exposed to the atmosphere for a long time often cause overheating faults due to poor contact.
3. Internal faults in electrical equipment. This refers to faults caused by electrical circuit failures and deterioration of insulating media that are blocked in solid insulation, oil insulation, and inside the equipment housing. According to the internal structure and operating state of various electrical equipment, according to the theory of heat transfer, the conduction and convection caused by the metal conductive circuit, insulating oil and gas, and the thermal profile of the temperature distribution appearing from the outside of the electrical equipment can be determined. An internal fault.

The 85W Macbook Charger MagSafe 1 or MagSafe 2 Power Adapter features a magnetic DC connector so if someone should trip over it, the cord disconnects harmlessly and your MacBook Pro stays put safely. It also helps prevent fraying or weakening of the cables over time. In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection.
When the connection is secure, an LED located at the head of the DC connector lights up; an amber light lets you know that your notebook is charging, while a green light tells you that you have a full charge. An AC cord is provided with the adapter for maximum cord length, while the AC wall adapter (also provided) gives you an even easier and more compact way to travel.
Designed to be the perfect traveling companion, the adapter has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage.
This power adapter recharges the lithium polymer battery while the system is off, on, or in sleep mode. It also powers the system if you choose to operate without a battery.
Compatible with MacBook Pro with Retina display.
