Dayten just to help you out you just listed 4 chargers but one of them 4 has a built in Power Supply being the 16x7.If you already have a power supply for the other chargers then go the 16x5 or CDC charger(Same thing)without Integy's VESC technology.
I will say I like the Pitbull better than the Mill and Pulsar expecially if you have a discharger.
Goodluck with your purchases's guys.
