[SBLOCK=OOC]I have an idea on how the device could work:
You have a device that work like that:
Boost [Shrinking and Morph] 8 [4pp/rank + 2 pp = 26pp]
extra: Total Fades
power feat: Slow Fade 2
With that, you have a power that can maintain Morph and Shrinking at power level 4 (in other word, cancel Carrion's Growth and giving him +20 disguise) for 1 hour (I rounded it for ease bookkeeping).
This device is on a battery with 80 energy point (Or any other amount you wish). The boost ask 8 Energy points on each use. Which mean, the battery can sustain boost for 10 hours. Cedric can feed the battery with his power. For every whole hour he sustain Electricity Control target on the battery, the battery recharge an amount equal to the rank at which it has been use. (Which would probably means 2 where I can't drain electricity, 10 where I can). If CPU use his array during that hour, the battery doesn't recharge.
Now, if CPU want to create a battery backup, he could create a battery that gives 10 Energy Point per PP spend on that device.
Finally, if you wish, CPU could also draw from that battery. Each use of his electricty control he use would cost the battery a number of energy point equal to the number of rank his flaw is applied. (Example, a Blast at rank 2 would cost 0 Energy point, at rank 10, it would cost 8.) You could also not allow it at all. The latest would be simplier, the first would be more close to the concept of CPU.
If it is all too complicated, you can also just do as you mind too
