Power Supply for Pedalboards

The BFKK JP-05 is a portable power supply built for guitarists who need to run multiple effect pedals away from a wall outlet. It integrates a 7.4V 4400mAh rechargeable lithium battery pack that charges in about 2.5hrs. The unit delivers eight DC outputs plus a 5V/1A USB port for charging phones or tablets. It suits players who want a self-contained power source for rehearsals or busking.

Battery Life and Output Options

A full charge lasts more than 10 hours when powering eight analog pedals, but only 2 hours with high-current digital effect pedals. Four jacks supply 9V at 100mA, three provide 9V at 500mA, and one adjustable jack switches between 9V, 12V, or 18V at a maximum of 100mA. The USB port adds convenience for personal devices. A bright LED illuminates the pedal board and indicates battery level, while charging stops automatically when full.

Simple Setup With Current Limits

Connect each pedal to a matching voltage and current jack using standard DC cables; no software or drivers are required. The adjustable output jack requires the user to select the correct voltage before plugging in a pedal. Problems usually arise when a digital pedal draws more current than its assigned jack allows, causing the supply to shut down or the pedal to malfunction. Builders who need more than eight outputs or higher current on the adjustable jack should look for a larger unit.

Questions about this item

How long will the built-in 4400mAh lithium battery last before it needs replacing?

The 7.4V 4400mAh rechargeable pack charges in about 2.5 hours and runs for 2 hours with high-current digital pedals or over 10 hours with eight analog pedals; lithium cells typically keep useful capacity for several hundred charge cycles.

Which output hits its current limit first when I run a full board all day?

The four 9V 100mA jacks and the adjustable 9V/12V/18V jack at 100mA will reach their ceiling before the three 9V 500mA outputs, so plan your digital pedals on the higher-current sockets.

How hot or noisy does the JP-05 get during an all-day session?

The unit has no fan, so it runs silently; the battery and regulation circuitry stay warm but not hot during continuous use, and charging stops automatically once the pack reaches full capacity.
