   The iPhone 12/12 Pro and newer (except the 3rd generation iPhone SE and iPhone 16e) support Qi2 with iOS 17.4. [43] MagSafe Charging Case for AirPods (3rd generation) The wireless charging case for AirPods (4th generation) does not have magnets to automatically align with MagSafe chargers due to its smaller size.

3. Battery holder - Wikipedia

   en.wikipedia.org/wiki/Battery_holder

   Battery types such as the 9-volt have snap-on contacts. Battery holders for zinc-air batteries must not be completely air-tight since approximately 1 litre of air is required per ampere-hour of discharge per cell. The battery holder may include a valve integrated with the device power switch to allow air to be admitted when the device is ...

4. Battery pack - Wikipedia

   en.wikipedia.org/wiki/Battery_pack

   Battery cases are small power banks attached to the rear side of a mobile phone like a case. Power may be delivered through the USB charging ports, [18] or wirelessly. [19] Battery cases also exist in the form of a camera grip accessory, as was for the Nokia Lumia 1020. [20] For mobile phones with removable rear cover, extended batteries exist ...

5. Power management integrated circuit - Wikipedia

   en.wikipedia.org/wiki/Power_management...

   Many electrical devices use multiple internal voltages (e.g., 5 V, 3.3 V, 1.8 V, etc.) and sources of external power (e.g., wall outlet, battery, etc.), meaning that the power design of the device has multiple requirements for operation. A PMIC can refer to any chip that is an individual power related function, but generally refer to ICs that ...

6. Jumper (computing) - Wikipedia

   en.wikipedia.org/wiki/Jumper_(computing)

   Jumper pins (points to be connected by the jumper) are arranged in groups called jumper blocks, each group having at least one pair of contact points.An appropriately sized conductive sleeve itself called a jumper, or more technically, a shunt jumper, is slipped over the pins to complete the circuit.

7. Flexible battery - Wikipedia

   Carbon nanotube electrodes have been reported too: pristine, [7] and combined with Li 4 Ti 5 O 12, LiCoO 2, [8] or SnO 2. [9] Another development is the paper-thin flexible self-rechargeable battery that combines a thin-film organic solar cell with an extremely thin and highly flexible lithium-polymer battery. This recharges itself when exposed ...

8. Battery management system - Wikipedia

   en.wikipedia.org/wiki/Battery_management_system

   A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...

9. Electromagnetic shielding - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_shielding

   A laptop case with visible copper electromagnetic interference (EMI) coating shield on the inside. Such coatings are usually deposited by using electroless plating. It is applied both to home appliances and medical devices. [1] Typical materials used for electromagnetic shielding include thin layer of metal, sheet metal, metal screen, and metal ...
