The term 'phone charger feature' can be summarized as a device with prongs, which is a five-letter word. Prongs are two or more pointed projections that are used to hold an object in place. In the context of phone chargers, prongs are used to connect the charger to the wall outlet and provide power to the device. Prongs are also used to secure the charger to the device, ensuring that it does not become disconnected during use.
