I have a variety of chargers (wall plugs) and cables. The chargers I have include: iPhone, blackberry, Nexus 5 OEM, monoprice 2a, generic.
The highest mA charging combo I have found using max currentwidget value is the iPhone wall plug and the OEM nexus 5 cable. The monoprice cables are slightly lower than the OEM cables and the OEM Nexus 5 wall plug is slightly lower than the iPhone one. The monoprice wall plug was a huge disappointment and is close to the generic charger or USB charging.
I like to have wall chargers throughout the house so I can get the most charge quickly when I am running in and out of the house. I would like to find a consistent cable and wall plug manufacturer that provides a fast charging combo and just stick with it.
