there are already a few threads about this Topic, i.e. :
[Q] How fast does it the charging dock actually charge?
Charging dock for $15.50
Xperia Z2 Dock and Car Dock
Aluminum Magnetic USB Charging
Now there is one more, with a Poll! Why?
I want a thread where people could post if they have problems of slow charging with their docks/magnetic plugs. Important is to mention what ROM/Kernel you use and where they bought the charger. Also don't forget to mention what wallcharger you use, as most dock/cable come with USB connector only.
i'll make the first step:
i bought this dock from Ebay for 9 bucks.
Using Stock .402 Firmware with some xposed modules and Doomkernel v09
Official 1.5A Sony Wallcharger for europe and the same Cable into the MicroUSB port!
it takes around 7hours to charge from 1% to 75% ! Way longer than via microUSB port on the phone.
here a few pictures from the inside of the dock.... it's just a magnetic plug placed right^^
