To use the boost pack in Starfield, you need to unlock a skill first, equip a suitable pack, and then trigger it with a second jump input while in the air.

Basic steps: how to use Boost Packs

  1. Unlock Boost Pack Training
    • Open the Skills menu and go to the Tech or Science section (depending on how the guide labels it in your version), then find Boost Pack Training.
 * Spend **1 skill point** to unlock Rank 1; without this, your boost pack will _not_ fire even if itā€™s equipped.
  1. Equip a Boost Pack
    • Open your Inventory , go to the Packs category, and equip an item that specifically says it is a Boost Pack or has ā€œboost packā€ in its type (for example, ā€œBasic Boost Packā€).
 * Some early-game backpacks are just armor with no boost function, so if you donā€™t see any boost when you try to use it, doubleā€‘check the item name and description.
  1. Use the Boost in-game
    • On PC : press Space to jump, then press Space again while in the air to activate the boost.
 * On **Xbox controller** : press **Y** to jump, then **Y again in midā€‘air** to start boosting.

 * Watch the **Boost Bar** next to your health; this is your fuel, and it drains as you hover or chain boosts.

Think of it like a double-jump: the first press is a normal jump, the second turns on the rocket pack.

Extra tips for moving well

  • Boost packs can:
    • Help you cross gaps or climb onto rooftops and high ledges.
* **Negate fall damage** by tapping the boost just before landing to slow your descent.

* Make traversal on big, vehicleā€‘free planets much faster, especially when youā€™re overā€‘encumbered.
  • Higher Boost Pack Training ranks :
    • Reduce fuel usage.
    • Make fuel regenerate faster.
    • Let you boost longer and more often.

Types of Boost Packs (quick scoop flavor)

There are several main Boost Pack styles that change how your jump feels.

[5] [9][5] [5]
Boost Pack type How it feels / plays
Basic Boost Pack Standard short boost; good allā€‘rounder for early game traversal.
Power Boost Pack Stronger, punchier vertical boost; good for reaching high places quickly.
Balanced / Tactical variants Tradeā€‘offs between fuel consumption, control, and jump profile; useful once you fineā€‘tune your playstyle.

Mini ā€œQuick Scoopā€ usage checklist

  • Do you have Boost Pack Training Rank 1? If not, grab it right away.
  • Is the item in your Pack slot actually labeled as a Boost Pack? If not, swap to one that is.
  • Are you doubleā€‘tapping jump (jump, then jump again in air) rather than holding it? Timing matters for consistent boosts.

Why it matters right now

Boost packs became one of the standout movement tools in Starfield at launch and remain a core part of most builds in 2024ā€“2026 discussions, especially for players who like exploration-heavy, ā€œparkour across the outpostsā€ styles of play. As Bethesda hasnā€™t added ground vehicles, a wellā€‘used boost pack is almost mandatory on large, lowā€‘gravity worlds.

TL;DR:
Unlock Boost Pack Training , equip a real Boost Pack in your Pack slot, then jump and tap jump again (Space on PC, Y on Xbox) while watching your fuel bar so you donā€™t run dry midā€‘air.
