The 
BatPack / 
LapPack charge held tools. 
Electric Jetpack: hold space = thrust, WASD steers (sprint = faster), sneak+right-click = hover mode (sneak = descend). More battery and speed: 
Advanced Jetpack (1M EU, charges tools) and 
Nano Jetpack (3M EU, protects like the nano chestplate).
The 
Jetpack flies on fuel: sneak+right-click it in your hand to refuel with 
coalfuel cells.

1 × Coalfuel CellThe NanoSuit has no normal armor: it absorbs damage only while charged (full suit 90%, 5,000 EU per damage point, boots also falls) — empty it does not protect at all, so keep it charged. QuantumSuit (100%, 20,000 EU per point): helmet (air, cures poison, feeds with 
tin cans), chest (flight + fireproof), legs (sprint speed), boots (super jump, no fall damage).
