I've never owned a wireless charger. But from what I saw from looking in the forum for my nexus 5. They take much longer to charger. In fact it goes usb 3.0 (fastest now) at like 1 1/2 hours or so, then micro USB at like (3 hours), then wireless charging supposed to take double the time of micro USB. It more for over night use not a quick charge. Hope it helps
A good and essentially correct summary. But there are exceptions and cavets.
While most USB 2 ports are rated at ~ 0.5A it varies and newer notebooks in particular may have USB 2 ports capable of 1A +.
Most AC adapters (aka travel adapters ) are typically, either 0.7 or 1A. But a decent full size AC adapter will be ~ 2A.
Also note that the phone will limit it's current draw when using a standard data cable so as not to overtax an USB port. To maintain a maximal charging rate when connected to a high capacity USB 2 port or USB jack on an AC adapter, a "charging" or power cable should be used. A charging cable has the two data lines shorted, to let the phone know that you are (ostensibly) connected to a high current source, rather than a standard USB 2 port.
And wireless chargers vary substantially in maximum output current from ~ 0.3 to ~ 0.9A. Most are also sensitive to ideal positioning. A randomly placed phone may charge at a substantially reduced rate, due to the reduced coupling efficiency of a random orientation.
