Even accounting for USB PD 3.0 requirements mentioned above, no system will ever be 100% efficient. Even if we ignored the industry specifications and built a 15W adapter for the 15W wireless charger, it wouldn't meet the minimum requirements to charge at full speed. If this stops you from reading further, here's the takeaway: if you don't want to buy Apple's USB-C AC adapter, any USB-PD 3.0 one with equivalent specs will do to get that faster charging speed, and a lesser one, won't. - PD Power Delivery is a new universal multi-voltage charging standard that dynamically negotiates power output over a PD Type-C connection to safely and efficiently recharge a wide range of compatible devices. Apple recommends using a 20W adapter, but doesn't specify what spec is needed. No system is inherently perfect, and every system will lose efficiency in charging based on multiple factors: These characteristics affect regular charging over a cable plugged directly to a device, so a 15W adapter connected to a suitable cable will still only charge less than 15W due to efficiency losses.

USB cable with a USB-C plug and a USB-C port on an laptop Main article: USB-C Developed at roughly the same time as the USB 3.1 specification, but distinct from it, the USB-C Specification 1.0 was finalized in August 2014 [26] and defines a new small reversible-plug connector for USB devices. This is why it defaults to the 5V x 2A supply when using the 18W adapter, and will do the same with most but not all existing 60W USB-C power adapters. On the surface, it may look like any other USB So while Apple could have gone with an older spec for its 15W charging requirements, it decided to engineer a safer and more efficient solution by relying on the newer spec. Will the power supply say: Oh, Im missing a signal on 3 or more wires, so it must be a primitive device, so Ill only send 5V at 2.4A But not every USB-C port is the same, and not every USB-C cable you can buy works the same way. Purchasing the Apple 20W adapter with the demanded specs for the full 15W charging from quality manufacturers will get you the desired results. The USB Type-C Specification 1.0 was published by the USB Implementers Forum (USB-IF) and was finalized in August 2014. With USB PD, USB Type-C ports can be either a source, sink or both. Tests show around 10W or less when used with adapters below 20W. USB-C (formally known as USB Type-C) is a 24-pin USB connector system with a rotationally symmetrical connector..
