Based on the information from industry insiders that ChargerLAB has acquired, Apple's recently released 40W charger represents a significant leap forward in terms of size. Its dimensions are roughly on par with those of the currently popular 20W charger. This new charger boasts a foldable plug design, which greatly boosts its convenience for storage and portability. Crucially, without any increase in its physical dimensions, there has been a substantial improvement in its power density. Power density is a vital parameter used to assess how well a charger balances its size with its performance capabilities.
