Ancient power modulator

From The Stargate Omnipedia

Device deduced by the information in the Ancient repository of knowledge, allowing an incredible boost of power to the Stargate. Though not Ancient in materials, Jack O'Neill unintentionally designed the portable piece of technology from the new knowledge in his brain.

When connected to the power source from which the Stargate feeds (Main Breaker Quadrant B), the modulator allows the Stargate to siphon energy 10 times the maximum available amount, but preventing a dangerous overload long enough for the Stargate to activate.

This device is powered by liquid naquadah, which can be gathered from a Jaffa staff weapon.
