Palmer (press release May 9, 2016)
Portable power supply
The Palmer BATPACK is a portable power pack that works like a power bank and is especially designed for powering effect devices on the pedalboard. Available in two models: BATPACK 4000 (4000 mAh battery capacity) and BATPACK 8000 (8000 mAhbattery capacity). Both power packs are optimized for use with Palmer Pedalbays. But these light-aluminum, full-metal devices also contain twelve mounting openings so that they can be used with other boards.
Two insulated 9-volt DC outlets each provide 500 mAh. The long-life 7.4-volt lithium-polymer cells take four hours to charge in the BATBACK 4000 or eight hours in the case of the BATBACK 8000. When fully charged and depending on the power consumption of the connected pedals, the power supply will last for four (BATPACK 4000) or eight (BATPACK 8000) hours.
Remaining battery life is conveniently displayed on the five-segment LED. The BATPACK is also fully functional while being charged. Devices such as smartphones and tablets can also be charged via the 5-volt (1 A) type-A USB outlet.
