We raised the bar on the X4 and equipped it with a built-in AC power supply. Our new X4 AC Plus, has four-port computer controlled capability with a built-in 22 amp power supply which can be powered by a standard 120 volt AC household current. Simple to use and utterly reliable, this com- pact charger with battery management and integral balancer features four identical and indepen- dent 50-watt power outputs, for a total output power of 200 watts. Each port of the X4 AC Plus can handle up to a 6S Lithium pack, 15 NiCd/NiMH cells or 6-12 volt lead acid batteries. Four individual balancing ports eliminate the need for a separate balancer when charging Lithium batteries. Its twin fan cooling system with an internal sensor for controlling fan speed provides the utmost in efficiency and safety. The X4 AC Plus can accept a variety of power inputs including the option of attaching it to a 12-volt car battery or a 11–15 volt (20 amp minimum) DC power supply.
