Bottle Station

From Teletraan I: The Transformers Wiki

The Bottle Station (sic) is a large trailer designed for the purpose of transporting vast quantities of Pepsi to any thirsty sentients Pepsi Convoy may encounter in his travels. It presumably is linked to Pepsi Convoy's CO2 gun.

Its combat effectiveness is unknown, but one would imagine that being made sticky from powerful jets of carbonated syrup beverage is certainly a detriment in battle, plus it can't be good if it gets into a Transformer's gas tank.
