You can manifest powers that last longer than normal.
Benefit: To use this feat, you must expend your psionic focus. You can manifest an extended power. An extended power lasts twice as long as normal. A power with a duration of concentration, instantaneous, or permanent is not affected by this feat. Using this feat increases the power point cost of the power by 2. The power’s total cost cannot exceed your manifester level.
