# Booster

A timed multiplier on credits, experience or crew training, activated by a player or by a clan for everyone online.

Also known as boosters, personal reserves, personal reserve, credit booster.

Boosters run for a set duration once activated, multiplying one kind of income. They stack with a [premium account](/glossary/premium-account.md), so a [session](/glossary/session.md) planned around them earns far more than the same [battles](/glossary/battles.md) played cold.

[Clans](/glossary/clan.md) have their own version: [Stronghold](/glossary/stronghold.md) reserves, which a [commander](/glossary/crew-role.md) activates for every member currently in the game, which is one of the practical reasons to be in an active clan.
