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

With the included AC adapter, the S5 can charge at up to 2.1 amps or so. USB 3.0 maxes out at 1.0 amp, and wireless chargers are about 0.7 amp. The slowest is really USB 2.0, which is only like 0.45 amp.

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.

.

So if I plug my wireless charger into the white plug in adaptor that came on the charger that came with my Gs5 new that would give me maximum output voltage to my wireless charger?please correct me if Im wrong. Thanks In advance!!!
