To use a boost pack in Starfield, you need to do three things: unlock the Boost Pack Training skill, equip a boost‑enabled pack, and then double‑tap your jump button (space on PC, Y on Xbox) to activate it in mid‑air.

1. Unlocking Boost Pack Training

You can’t actually use the boost function at all until you spend at least one skill point in Boost Pack Training.

  1. Open the character/skills menu (Tab on PC, Menu on Xbox).
  1. Go to the Tech (or Science/Tech depending on UI labeling) skill tree.
  1. Find Boost Pack Training and spend one skill point to unlock Rank 1.
  1. Once Rank 1 is unlocked, boost packs become usable on any suit that actually has a boost pack module.

Ranks of Boost Pack Training give bonuses like reduced fuel use and faster fuel regen, and higher ranks double those bonuses, so it’s a very strong early skill.

2. Equipping a Boost Pack

Not every suit/pack you pick up is actually a boost pack, especially in the early game.

  • Open your inventory, go to the Packs or spacesuit section.
  • Equip an item that specifically lists Basic Boostpack , Power Boostpack , or another boost‑type in its description.
  • If it doesn’t say anything about a boost pack in the description, it won’t fire even if you have the skill.

Power Boostpacks are considered a big upgrade over basic ones thanks to better boost performance and are worth buying if you see them at vendors.

3. How to Actually Boost

Once you have the skill and a proper pack equipped, the inputs are simple but a bit hidden.

  • PC (keyboard/mouse):
    • Press Space to jump.
    • While in the air, press Space again to trigger the boost pack.
  • Xbox controller:
    • Press A (or Y, depending on your control layout) to jump.
* Press the jump button again while airborne to boost.

You’ll see a boost bar above your health bar that shows your remaining boost fuel; when it empties, you can’t boost again until it refills.

Movement Tips

  • You can boost in any direction you’re moving, which helps for crossing gaps or dodging in combat.
  • Basic packs give a modest height bump, while better packs let you hover longer or chain more directional bursts.
  • You can often cancel or reduce fall damage by triggering a boost just before you hit the ground.

4. Why Boost Packs Matter (Quick Scoop Style)

In 2023–2025 discussions, players frequently call boost packs a “game changer” for exploring harsh or vertical planets and fighting in open areas.

  • Great for climbing cliffs, reaching loot, and traversing low‑gravity environments.
  • Almost essential in zero‑G and ship interiors for quick maneuvering.
  • Often recommended as an early‑game priority skill on forums and guides.

“Press tab, go to skills, go to tech, and be sure that ‘boost pack training’ perk is enabled. Make sure to unlock it with skill points if you haven't done so.”

5. Mini FAQ & Forum‑style Notes

Q: I have a pack equipped but nothing happens when I double‑jump. Why?

  • You probably don’t have Boost Pack Training unlocked, or your pack isn’t actually a boost pack (check the description text).

Q: Is one rank of Boost Pack Training enough?

  • One rank lets you use it at all; higher ranks reduce fuel cost and speed up regen, which makes flying around feel much smoother.

Q: Is this still relevant now?

  • The basic requirement—have Boost Pack Training and a boost‑type pack, then double‑tap jump—has remained the same across guides and community posts since launch.
