A box of spark pads from The Resistor
A spark pad is a type of device that was sometimes carried by droids. In the year 9 ABY, the droid cantina known as "The Resistor" on the planet Plazir-15 was giving out spark pads branded with its name to its customers. This situation resulted in Mandalorians Din Djarin and Bo-Katan Kryze launching an investigation into the cantina, triggered by the fact that one of the patrons, a B2-series super battle droid, turned rogue and used a spark pad to attack the city. The Mandalorians were thus led to believe that "The Resistor" was the hideout of the rogue droids.
