MagSafe, a magnetic technology embedded into the internal engineering of iPhone 12 models, was originally created as a safety feature for MacBook charging cords. It creates a new ecosystem of accessories for easy attachment and faster wireless charging. The cost of a wireless power bank with Magsafe ranges from INR 5000 to INR 7000. Apart from being expensive, it is very difficult to procure one from the market.
This DIY design is of a wireless power bank with Magsafe, that can not only charge iPhones but also other compatible devices (including IoT devices). It offers the benefit of having a wireless powering system, MagSafe technology, and a USB charging system that is compatible with many devices.

The size of the battery is important to design the case. Both the battery and the charging module have to be fit inside the case. An area for input power charging (USB) and output power is cut out on the case. A cavity is also made on one wall of the case for the coil and MagSafe magnet to be placed, as shown in figure 3.
