Introducing the T-REX FuelTank Junior, a compact yet robust power supply unit that packs a serious punch for your pedalboard. With five isolated outputs, this lean and mean power supply delivers clean and quiet power to your 9-Volt effects pedals, making it a versatile solution for powering various pedal types. The FuelTank Junior boasts worldwide usability, featuring a switchable voltage selector for both 115V and 230V mains, allowing you to take your pedalboard on tour without limitations. Don't let its compact size deceive you – the FuelTank Junior is designed to fuel your pedalboard with unwavering power.

Understanding Your Pedal's Power Needs

Before connecting your pedals to the FuelTank Junior or any power supply, it's crucial to understand two vital aspects: the voltage your pedal requires and its power consumption. T-Rex pedals generally accept voltages between 9 and 12 volts. If your pedal gets less voltage than required, it might alter its sound or produce no sound at all, while higher voltage can potentially damage the pedal. Additionally, knowing your pedal's power consumption (measured in mA) is crucial. The FuelTank Junior, with its 5 isolated outputs delivering 120 mA each, is an ideal match for pedals that accept 9 volt DC and require less than 120 mA.
