A Mongocharger is a device used by most fairy smugglers. It resembles a thin black box with a spike on the bottom. It is suckered on to a vehicle dashboard and the spike (the end of a retractable power cord) is plugged in to the vehicles power cable, connecting it into the mongochargers "clean nuclear battery", an omni sensor and "strong computer". Then hack in to the vehicles system (rapidly boosting its speed: "walking speed becomes "1/100 of 1% of the vehicles top speed" and that was with a toy car!) and an LCD screen and speaker relay information to the driver. One known user was Doodah Day, who used it to speed up Beau Paradizo's toy car in The Lost Colony.
