2. Current clamp - Wikipedia

   en.wikipedia.org/wiki/Current_clamp

   An electrical meter with integral AC current clamp is known as a clamp meter, clamp-on ammeter, tong tester, or colloquially as an amp clamp. A clamp meter measures the vector sum of the currents flowing in all the conductors passing through the probe, which depends on the phase relationship of the currents. Only one conductor is normally ...

3. MagSafe - Wikipedia

   en.wikipedia.org/wiki/MagSafe

   The Apple MagSafe power adapter's 1-Wire communication chip is located inside the MagSafe connector itself; the cable does not carry the data line to the power adapter enclosure. [18] The maximum voltage supplied is as follows: 14.5 V DC for the 45 W units supplied with MacBook Air; 16.5 V DC for the 60 W units supplied with MacBook and 13 ...

4. Inductive charging - Wikipedia

   en.wikipedia.org/wiki/Inductive_charging

   Applications of inductive charging can be divided into two broad categories: Low power and high power: Low power applications are generally supportive of small consumer electronic devices such as cell phones, handheld devices, some computers, and similar devices which normally charge at power levels below 100 watts.

6. AC adapter - Wikipedia

   en.wikipedia.org/wiki/AC_adapter

   An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
