Strengthens the active shield if powered. Multiple boosters stack in effectiveness.
— In-Game Description
The Shield Booster is a utility module that is used to increase the strength of a ship's shields.
The Shield Booster increases shield strength by a given percentage of the base shield automatically and continuously once installed. It will continue functioning as long as it is powered and unbroken. Note that the Shield Booster is not a substitute for a Shield Generator, and will provide no benefit if it is installed on a ship that does not already have an active Shield Generator. If multiple Shield Boosters are installed, the boost effect stacks additively.
The following modifications can be applied to this module by Engineers to enhance its abilities:
- The Shield Booster was added in the Wings Update (1.2) on March 10, 2015.
- The Elite Dangerous: Horizons 2.3 update was planned to include diminishing returns for stacking Shield Boosters, but these changes were rolled back shortly before release and never implemented. As seen in the 2.3 beta, the changes would have reduced the effectiveness of Shield Booster stacking after a cumulative 80% boost, with a hard cap at 150%.
