There is an unfiltered DC extension on either side. The extensions are unfiltered to preserve battery life, since the filters account for most of the power consumption. + +## Fact-finding results + +I did some experiments to validate if the concept of ZGP filters with the myVolts USB adapter would work. + +- myvolts connected to 7 ZGPs first (no pedals), then connect myvolts to battery + - doesn't work (ZGPs flicker on and turn off immediately), probably due to inrush protection in the myvolts + - plugging USB in and out repeatedly doesn't work +- myvolts connected to battery first, then connect myvolts to daisy chain with 7 ZGPs (no pedals) + - doesn't work at first (ZGPs flicker on and turn off immediately), probably due to inrush protection in the myvolts + - plugging DC jack in and out then works (ZGP caps are charged -> able to power on) +- myvolts connected to battery first, then connect myvolts to daisy chain with 7 ZGPs and 5 pedals + - doesn't work at first (ZGPs flicker on and turn off immediately), probably due to inrush protection in the myvolts + - plugging DC jack in and out then works (ZGP caps are charged -> able to power on) + +- myvolts connected to battery, no load + - after 15 minutes, battery powers off + - connecting pedals does not wake it up + - pressing battery power button does not wake it up + - only way is to unplug/replug myvolts |
