I use the standard Samsung wall plugin in my bedroom for overnight charging, output is 5V & 2000 MA
I use a USB Power Adapter in my office, Model CT47U-USB that has dual ports, setup for one to have 500 MA and the other for Tablets at 2100 MA.
One thing that I've done that I believe helps more than anything else is to make sure that I have really good quality 'HEAVY' cables. I prefer the 'Blue' ones that you can buy from Amazon called the CITI Samsung Galaxy Nor 3.....
I also only use the USB 3.0 type cables. I even have an 18" (CITI Blue) version for my vehicle that goes with the 2.0 AMP charger for my car.
These are super heavy duty, and allow me to charge my Note 3 from 20% to fully charged in about 6 hours.
