You can channel divine energy more often.
Prerequisite: Channel energy class feature.
Benefit: You can channel energy two additional times per day.
Special: If a paladin with the ability to channel positive energy takes this feat, she can use lay on hands four additional times a day, but only to channel positive energy.
If I take Extra Channel and I have more than one class with the ability to channel energy, do I have to assign the extra uses to a particular class when I choose the feat?
No. In effect, the feat gives you two “floating” uses of channel energy per day, and you can use them with any appropriate class you have which grants the channel energy ability. For example, if you’re a cleric/necromancer, each day you could use 1 channel as a cleric and 1 as a necromancer, 2 as a cleric and 0 as a necromancer, or 0 as a cleric and 2 as a necromancer. Note that this does not give you an extra two uses of channel energy for *each* class that grants it—the feat gives you exactly two extra uses per day. [Source]
