Description
Bass rigs eat power differently than guitar boards — heavier envelope filters, octave pedals, and compressors pull more current, and the last thing you need mid-set is a power supply that quits without warning. The Big Joe Li2 Power Box PB109 is a small-footprint rechargeable lithium battery unit built to handle that load, delivering up to 1 Amp of output to run multiple pedals or high current-draw effects off a single charge.
What sets it apart is the smart battery display: a 3-digit blue LED readout tells you battery charge percentage, time remaining, and current draw in real time, so you know exactly how much runtime you’ve got left under your actual pedal load before you ever step on stage. No guessing, no swapping batteries between sets.

Tough enough for the road, small enough to tuck into a corner of your board, and smart enough to keep you informed — the PB109 is a practical way to cut the cord and keep your low end powered up all night.
