From Guild Wars 2 Wiki
Double-click to prime the bottle for capturing an electric charge.
— In-game description
- Double-clicking the bottle will make it account-bound.
- A single capacitive bottle may be used continuously during the Bolt III: Zap collection
- Double-clicking the bottle will create an effect called Primed Bottle which lasts 15 minutes and allows capture of any collectible item without refreshing the effect.
- If creating the bottle does not add it to the Bolt III: Zap collection, you can manually add by right clicking on it and selecting "Add to Collection".
