★★★Please note our battery DC port is inner Positive(+), outer Negative(-). But most guitar pedal input port is inner Negative(-), outer Positive(+). If you want to use this battery to power the guitar pedal, you must need a reversed polarity cable to connect the pedal with our battery, or will damage the guitar pedal. Our package not include this reversed polarity cable.
