Jetpacks were typically slower than rocket packs, though were lighter in weight and quieter in operation as a result.

Further, even under ideal flight conditions the turbines were vulnerable to debris, dust, and other factors - should the intake mechanism become damaged or clogged, the insufficient intake pressures would cause a sudden loss of altitude. While capable transportation, jetpacks had a number of limitations, most notable being that they required atmosphere to operate zero, low, or high atmosphere pressure caused numerous difficulties in operation. Though more advanced controls could be used through the use of a HUD. Stock jetpacks were typically worn on the back, and controlled through wrist and hand controls that adjusted the angle and pitch of intake and exhaust vanes. As such, while most jetpacks had a number of set "charges" and a minimum "cool down time" that varied across given models, the internal regulator's controlled release of these charges gave the impression of continuous operations and flight. The thrust produced by this single burst was then regulated by a series of internal regulators that distributed the energy over several seconds.

Jetpacks functioned by use of an intake that pulled surrounding atmosphere into an ignition chamber arrays of miniature turbines then combined minute amounts of fuel to produce a burst (or "charge") of thrust for lift and maneuvering.
