The GraviChestPlate is an armour item added by the GraviSuite mod that is worn in the chest slot. It fulfills all of the roles that the Quantum Chestplate fulfills in addition to storing 10 times as much EU (10 million), allowing the player to fly as if the player were in Creative mode, and providing energy to electric tools such as the Mining Drill or the Chainsaw. This means that tools or armor that continually use power, such as Modular Powersuits, will continually be refilled by the GraviChestPlate regardless of the Gravitation Engines being on or off. The GraviChestPlate can receive power from the Solar Helmet or the Ultimate Solar Helmet. It can also be charged or discharged in an MFSU.
The GraviChestPlate also consumes power more quickly (as do the Quantum Leggings and the Quantum Boots) when the Boost key (default:
Ctrl) is pressed. This function only functions if the Gravitation Engines are turned on (toggleable with
F) This causes the EU consumption to triple, but flight becomes affected by the Quantum Leggings' sprinting abilities, more than tripling in speed.
If the Gravitation Engines are left running, the chestplate will consume EU regardless of whether or not the player is flying. The Gravitation Engines will run for 16 minutes and 15 seconds before the chestplate runs out of power. The Gravitation Engines consume 512 EU/t while active, allowing an Ultimate Solar Helmet to keep pace with the Gravitation Engines if it is daytime and the sun is visible. The Gravitation Engines consume ~1536 EU/t if the boost key is held.
The GraviChestplate has a maximum flying height of around 260; compared to an Electric Jetpack which has a maximum height of around 190.
