How to Charge and Refuel an Iron Jetpack

Charging From an Energy Source

A jetpack stores energy internally and must be charged before flight. With the jetpack equipped or held, connect it to any compatible energy source — a generator, energy cell, or charging block — using cables or by placing the jetpack in a charging slot. Energy transfers into the jetpack until its internal buffer is full. The charge bar on the jetpack's tooltip shows current stored energy.

Refueling Logic

If your jetpack uses a fuel slot, insert the accepted fuel item into that slot. The jetpack burns fuel to generate the energy it stores, so a full fuel slot keeps it topped up during long flights. Check the tooltip for the current fuel level and energy level separately — a jetpack can have fuel but no charge, or charge but no fuel, depending on its design.

Keeping It Ready

• Charge the jetpack fully before exploring far from your base.
• Carry spare fuel items in your inventory for mid-flight refueling.
• Place a charging station near your main exit so you can top up before every trip.

Higher-tier jetpacks built with Advanced Coil, Elite Coil, or Ultimate Coil hold more energy and burn fuel more efficiently, reducing how often you need to recharge. Build the next coil tier when you find yourself running dry too quickly.
