The Palmer BATPACK4000 is a compact battery power supply for effect devices. Thanks to its 4000 mAh lithium polymer battery and active filter circuit, it supplies power to pedal boards for up to four hours without interference. Two 9 Volt outputs with 500 mA each are available for connection, while smartphones or tablets can also be charged via the USB-A port. Last but not least, a display consisting of five LEDs provides information about the charge level of the battery.
